More Changes in Dr. Kioni Dudley

I take ZanthoSyn for life extension. In many ways it restores abilities I had in the past. In recent weeks, I am seeing new, controlled movement, and, everday, increasing movement, in my foot, which has been quite dead for a couple of years.

Kioni D. | August 16, 2022

Can’t walk without it

It’s a part of our daily routine. Knee acted up when I was unable to purchase for several months. Hope it’s always available

Clay K. | July 28, 2022

Excellent product

I’ve tried others and they don’t compare.

Chris W. | June 28, 2022

Clean product but not sure of the results!

I've been taking it for several months. I haven't notice a major change. I'm going to continue for a bit longer to see if it makes a difference. It's not cheap so hopefully will work in a long run.

Nikta H. | June 25, 2022

Exceptional Product and Customer Service!

My monthly order was late due to shipping delays. I contacted customer service and got a call from CEO Mr. Dave Watumull. Dave was kind enough to offer me another bottle to hold me over until our order arrived, and he even offered to personally deliver it to my residence! Our order arrived along with our complimentary bottle. I want to say that I was very grateful to Dave and his team for providing us with exceptional customer service! Zanthosyn is a wonderful product that we take daily for our joints and aches. Mahalo!

Zanthosyn over Lyrica

After starting Zanthosyn I’ve been able to get off of Lyrica for my fibromylagia. Now I don’t have to try and operate off of a slow mind that forgets a lot of things. Thank you Zanthosyn!

PMR

i am suffering from PMR. it is a auto-immune disorder. i am taking two capsules daily now. getting some results but not out of the woods yet.

DAVID R. | May 18, 2022

A solid product

Have used astaxanthin, bilberry, lutein, fish oil, zeathanxin and others. I can rely on a liberal dose of zanthosyn, 12 milligrams, 90 ct bottle, to create a sense of protection against computer screen radiation during work hours as well as a sense of increased flexibility in motion.

Barnaby B. | May 16, 2022

Great service

Ordering is easy and fast. The product is good for me.

Van M. | May 11, 2022

Retired

I have used Zanthosyn more than 3 years. It helps for my back pain induced from hip injury, would definitely continue to use it.

HENG X. | April 26, 2022

Undecided

I am still not sure what this product is doing for me. I continue to take it because a friend said it worked for them.

Clyde H. | April 21, 2022

Not sure

Been using it for about a year and I’m not really sure. At the beginning it felt like an improvement. I have swollen hands so it somewhat easier to tell so I have decided to take a week off and then start again to see if I notice any changes

Jack C. | April 13, 2022

Good service good product

Excellent in every way

M D. | April 6, 2022

I can actually feel the difference

I am totally blown away by how quickly I could tell that ZanthoSyn was working on my joints. I was having really growing pain in my knees from walking 4 miles a day. However, since using ZanthoSyn, I have noticed that the pain was easing daily. I am so happy that I have starting using the product. Wish I started sooner. I highly recommend ZanthoSyn to anyone expriencing joint pain.

Alfred C. | March 19, 2022

Less Joint Pain

Without Zanthosyn, my knees have pain. Taking Zanthosyn regularly, twice a day with food, has shown a remarkable improvement. My knees don't bother me even when I walk 10k a day. I experimented after taking it for 2 years...I stopped for a month...and within a few weeks, my knees started hurting. I now incorporate Zanthosyn in my daily meds.

Patti L. | February 26, 2022

Amazing

I was having problems with my knee. I was sent to Physical therapy but it didn’t help. I went to Hawaii and to GNC. A worker over there introduced this medicine to me. I took I took the 60, 2 bottles after that my knee went away never came back. My mom also came with back pain. So I just introduced it to her it is really helping her. This medicine worked like in magic. I really recommend it for information.

Matilda M. | February 11, 2022

Less Joint Pain

I used ZanthoSyn in a clinical trial for 3 years...and noticed that I rarely felt knee joint pain which I used to feel daily. I stopped for 3 months after running out and to see what would happen. Knee pain came back within 2 months. I'm so glad I found this online to continue...and within a couple of weeks, no knee pain. Thank you!

Patti L. | January 19, 2022

Always excellent

Jean T. | January 19, 2022

So Far..So Good!

I recently started taking ZanthoSyn ..about a month and a half ago..and it seems to be working for me..for some minor aches and pains in my legs and it seems to be helping me with some back ache spasms I was having before I started on this product. Hopefully..this ZanthoSyn will continue to help me to stay in Good Health...

ZanthoSyn review

I use this to help keep me healthy. I've been using astaxanthin for awhile and find this version makes me feel better overall. I find, as I'm aging, taking the right supplements makes a difference. Zanthosyn is for me.

PMR

i am suffering from PMR and i am using Zanthosyn to help me lower and stop using prednisone . i think it is making a difference.

DAVID R. | December 4, 2021

Less Joint Pain

I was in the clinical trial...supposed to be for 2 years but the week that I ended it, COVID happened. Continued to use ZanthoSyn for another year and a half until supply stopped. In the 2 years, my knee joints stopped aching. My knees had been bothering me over 10 years prior to this clinical trial. I stopped taking ZanthoSyn to see what would happen. About a month later, my knees started acting up again, pain happening when walking more than 5k a day. I decided to order it and take it twice a day as I had during the clinical trial. After a few weeks, no pain again.

Patti L. | November 27, 2021

Review

I'm taking this for my arthritic knees. I think I've had some benefit, but not dramatic. I'll keep taking it.

Roger E. | November 20, 2021

A Key To Sustainability

I grew up playing all kinds of sports, but my favorite was always tennis. After 55 years of tennis, including 15 years as a tennis (teaching) professional, I estimate that I've run after and hit literally millions of tennis balls. The net effect (pardon the pun) is that my joints have taken a toll. Decades ago, I'd take aspirin, then switched to ibuprofen, just to cope with the pain I'd experience after playing tennis. After learning about the long-term side effects associated with taking NSAID's regularly, and researching the benefits of astaxanthin, though, I began taking Zanthosyn daily, about 15 years ago, at the advice of a long-time friend (and worthy tennis opponent).

I had knee surgery in 2006, while I was still coaching tennis part-time, and I believe astaxanthin aided my rehab process. I still play competitive tennis 3 times per week, and Zanthosyn helps me recover. I'm skeptical about any single product being a "silver bullet", so I'm not saying that Zanthosyn is a cure-all, but it definitely works. I'm a believer in a holistic approach to health, which is why I am careful about my eating, drinking, and sleeping habits, as well as my mindset. I also stretch every day, use sunscreen, and cultivate my relationship with God, which affects well-being in so many ways. Zanthosyn has been an integral component to the lifestyle I seek to maintain, and as such, I consider it a key to long-term health, in a sustainable fashion. It's well worth the price.

Jerry H. | November 19, 2021

Heading for 100

I'm 82 years old. I've been taking ZanthoSyn for longevity since reading an article in 2017 telling how it activated the FOXO3 gene in mice, causing them to live the equivalent of 100 years.

I believe that ZanthoSyn has activated my FOXO3 genes...and done so much more.

I started with one a day, then moved to two several months later, and four a year later. I noticed little anti-inflammatory effect until I reached four, and then it was only mild. I did begin growing hair on my arms again at four a day.

In January 2021, I moved to eight pills a day, 96MG, equivalent to the amount given to the mice. This was life-changing.

I couldn't lift my right arm up parallel to my shoulder. Now I stick it straight up, from both front and side, with no pain.

I had neuropathy in both feet and could feel nothing. Today feeling has returned 100%.

I had fallen more than twenty times, so fortunate to only gash skin and break a few fingers. I have my balance back, and haven't fallen for nearly a year.

Hair continues to grow on my arms, and now on my chest, which, like my arms, was hairless for several years. There's more hair on my head.

A year ago, I developed sciatica in my left leg, with excruciating pain from my butt-cheek to my toes. I started hot-laser treatments about the same time I increased my ZanthoSyn dose to eight. Today I only rarely have pain, and only in my lower leg.

I'm gaining muscle. My mind is clear.

Life is good.

I owe most of this to ZanthoSyn.

#1 in Inflammatory Pain Relief

As a psychiatric mental healthcare provider, I can't say enough positive things about Zanthosyn. For 3 years I've used it for neck/head pain, from advanced cervical arthritis (in the neck). I get complete pain relief at 5 caps daily. After taking naprosyn for a decade and beginning to get cardiac side effects and disabling pain if I missed a dose. Now, my heart is stable and pain is non-existent. I've also lost 15 pounds and haven't had my annual upper respiratory illness in the past 3 years. My cholesterol and my BP has normalized. I teach my patients about astaxanthin's benefits and encourage them to use it to target metabolic syndrome, a complication of psychiatric medications as well as the pain from inflammation. One of my female patients who has Fibromyalgia was able to come off pregabalin once she started taking Zanthosyn and her pain relief is superior without any side effects (which was the reason she wanted to get off pregabalin, e.g., mental fog, forgetfulness, sedation and dizziness). One of my male patients with Type 1 diabetes was able to reduce his daily insulin requirement by 75% and come off an insulin pump. The tremendous benefits of astaxanthin you can read about on this website, I won't go into them here. Without Zanthosyn, I would not be able to work and I might have died of a heart attack had I continued to use naprosyn for my pain relief. I am very very grateful to have Zanthosyn in my life.

Great service

The product helps me so much. I highly recommend it.

Linda W. | September 29, 2021

Endorsed by Dr. Terry Shintani, MD, JD, MPH

My confidence in Zanthosyn from Kardax stems from Dr. Shintani's finding that it is much better absorbed by the body than the BioAstin brand. He also cautioned against from purchasing Zanthosyn from GNC after that retailer was acquired by an entity from China. I take several supplements daily and am unable to isolate the effects of any single supplement.

Claire N. | September 19, 2021

Good!

Love it, been using for a number of years.

However, I miss my bottle of 90!

It reduced the swelling of my injury greatly. I was able to reduce the intake of Rx on pills. My only gripe now is that because of a recent financial fallout, I had to switch to a cash payment, which has either delayed or stopped the recent order.

I've been taking ZanthoSyn for 12 months now. I noticed my blood test is improving gradually. My A1C was at 8.6 about a year ago. After I started ZanthoSyn is improved to 7.3. My next test it was 6.7 and the most recent test it dropped to 6.1. If my next test gets below 6.0 maybe my doctor will get me off the pills.

Excellent product

My cholesterol was very high several months ago. I restarted taking ZanthoSyn and had my cholesterol checked again in May. My doctor was astounded at how the number came way down. I believe the ZanthoSyn was a big factor in those good results. No need for statins I was told! My husband and I will be taking ZanthoSyn for a long time! I can't tolerate anti inflammatory drugs and so ZanthoSyn has been my savior because I have arthritis and that's why I started taking it a couple years ago. It has really helped with pain and inflammation. We are very grateful for this product and will use it the rest of our lives! Thank you!

THE MOST AMAZING ASTHAXANTHIN!

This must be the purest form of natural Astaxanthin! I felt the Zanthosyn in my system almpost immediately! Amazing

V E. | April 16, 2020

ZanthoSyn is a great supplement for Seniors and/or Athletes

As a senior (over 60 years old), I use ZanthoSyn as a ""preventative"" (for arthritis and joint aging) and also for faster recovery after vigorous activities or exercise. I know for a fact that many marathon and triathlon athletes use astaxanthin for recovery and that's how I was introduced to it. ZanthoSyn is a pure form of astaxanthin, which is a great anti-inflammatory without the negative side effects of drug store products and that is why it is part of my daily regimen.

ARNOLD K. | February 28, 2020

Zanthosyn

Unfortunately I had to stop taking it as I was breaking out in purpura on my arms and face. When I stopped taking ZanthoSyn the bruising stopped.

Aloha,

I have recently started using this product. I am on a 4 capsule regiment and have not seen any results that i can notice. I am my 2nd bottle. I know that the results are not going to happen overnight. I just want to know when i can expect some results. I'll have to order another 2 bottles to keep up with the regiment i am on.Thanks

Clyde H. | December 1, 2019

My husband falls a lot. I noticed that his bruises and scrapes heals so much faster. He seems to have more energy too.

Katherine K. | October 31, 2019

Great dietary supplement

My A1C was down almost 1 point from 7.0 to 6.0. Even if I changed my diet by eating less carbs and less sugar the number was a welcome change.

I felt that taking this

I felt that taking this supplement helped me recover much quicker from my intense workouts and I also noticed a difference when stooping down to lift up pots and pans from the lower cabinets..... less stiffness in my knee joints.

cheryl t. | July 29, 2019

Amazing!

I never write reviews but am totally happy! I have been to physical therapy and acupuncturists and chiropractic and massage therapy and the gym and stretching but nothing helped very much with my rotator cuff tendinitis. I began taking zanthosyn 3 weeks ago and the pain is barely noticeable. So so very happy GNC recommended this for inflammation.

Briana H. | July 24, 2019

IT WORKS!

AMAZING AFTER A FEW DAYS OF USE THE INFLAMMATION IS GONE!!

Francis H. | July 22, 2019

INFLAMATION

ITS AMAZING! I am an athlete and always have issues with inflammation this product has reduced by 80%! After a week or so it really kicks in. I take two per day with a little healthy fat. I ran out last month and after a few days the old pains and inflammation returned. Its a great product and I will not be without my ZANTHSYN!!!!!!! Thank you CARDAX CORP

Anti inflammatory

I believe that due to ZanthoSyn I have decreased my inflammation markers.

Antonia L. | February 23, 2019

Amazing anti-inflammatory

I was having difficulty with pain in my ankles when I awakened in am, it would improve during the day but no resolved. After taking ZanthoSyn for 1 week I noticed when I awakened, and had to take the dog out, walking down the 1.5 flights, was no longer painful. I also noticed that the pain in my right shoulder post rotator cuff repair was no longer there. I am amazed. I have started my husband on this once daily and he has less c/o pain. He is a retired firefighter, and continues to work construction with less joint discomfort.

Mary M. | January 16, 2019

Mark B. | November 9, 2018

Ended NSAID meds and feeling great!!

A year after shoulder surgery, I'd had enough of my NSAIDs (non-steroidal anti-inflammatory drugs). Stomach aches and bloating got worse and it was inevitable I'd be prescribed yet ANOTHER drug....aka vicious cycle. So I was fortunate to read (Midweek mag) about your astaxanthin and the science done at JABSOM. And with the resent volcanic eruptions, the idea of taking a more controlled pollutant-free anti-inflammatory supplement made all the sense in the world. I now take Zanthosyn daily, usually with some buttered toast or with a couple tablespoons of cottage cheese. The bonus is that I don't get sunburned and my wrinkles have faded better than any cream I might've spent a week's pay on. (Oh btw, thanks for that too.) All my best to the Zanthosyn team and keep up the great work!

Lianne I. | October 19, 2018

Amazing product

We take 8-10 Zanthosyn a day and recommend it tour patients. We are finding Zanthosyn is excellent for reducing and eliminating opioid dependence.

So far, so Good!!

My son, husband, and I are all using the ZanthoSyn for healing liver, lowering cholesterol, and keeping down inflammation. We've started using this product recently, but, so far, my joint and muscle pain has been greatly reduced! Looking forward to my next blood test to see how the cholesterol looks. My son's fatty liver and thyroid levels are returning to normal, and I'm sure the ZanthoSyn has helped! Great product! I've been recommending to friends and family! Thank you!

Waiting

After 2 weeks, I can't be sure of the effect on me. I'm hoping it will reduce my osteoarthritis pain. My current dosing is low, and I'll increase it if I see no significant improvements.

No noticeable difference

I did not notice any changes in the pain or swelling in my hands.

Excellent, I believe in the research and also in my own body which has less chronic inflammation symptoms.

ZanthoSyn is a great product!!

Being a former professional athlete and taking anti-inflammatory medication to help with pain throughout my career I didn't realize the potential side effects, especially long term effects of anti-inflammatory medication. I now can honestly say that I am very fortunate to have been introduced to ZanthoSyn. I have definitely noticed a difference in joint pains in my knees, feet, hands, and hip areas from the long term effects of playing ball. Inflammation is what leads to a lot of serious issues as we age. ZanthoSyn as been a game changer for me!

Matt A. | October 10, 2017

While I like the product,

While I like the product, it is a bit indigestible. Despite the fact I eat it with plenty fatty food, I keep "repeating" the product.

Bernardo V. | September 26, 2017

Four capsules a day and my wife's arthritis pain in her knees and legs is simply gone.

Going to bed at night with arthritis pain, then waking up in the morning to the same issue was demoralizing. We learned about ZanthoSyn, first from friends who had experienced wonderful results, then from a bit of independent study. We quickly figured out that one 12 mg capsule a day was an arbitrary dosage limit attached to countless over-the-counter dietary supplements by the FDA. We were absolutely convinced of ZanthoSyn's safety at higher dosages. After allowing some time to get the product into her system, my wife started some experimentation. She found that two capsules in the morning and two at night combined to be the dosage she needed. For all intents and purposes, she's been pain free ever since. No side effects. She's 70 and a bit of a human dynamo. She was just starting a new professional career. She didn't need arthritis inflammation screwing things up. Thank you, Cardax!

zanthosyn: nutrient for the gods

my experience with zanthosyn started out well, with your special operator named JANICE providing excellent service. this woman's performance was a tour de force in professionalism, politeness and good business etiquette. it was certainly a pleasure to come across such a well-trained representative like JANICE in today's often shabby business world. if she doesn't win the trip to hawaii as top employee of the 2nd quarter, then an injustice has occurred. realize the 5 star nature of this woman JANICE and begin the series of pay boosts to make her compensation approach her tremendous value to your company. thank you JANICE for your superb service!

Elizabeth S. | June 3, 2017

No Side Effects! Great results.

I have been using ZanthoSyn for several months now to address chronic lower back and hip pain. I am allergic to NSAIDs. I have no issues with the Zanthosyn and have found it to be very effective for the hip and back pain. It also helps with minor shoulder pain after swimming. I have not had any detectable side effects. I take 60mg daily at night after dinner.

Excellent, in terms of its ability to aid recovery from intense workouts. It now looks like it has the added benefit of activating FOXO3 as well!

richard a. | April 11, 2017

This stuff works!

I've tried different types of astaxanthyn over the years, and Zanthosyn is at least as effective, and without any of the ""side effects"" I experienced with the others.

Helps against the aches and pains

My first time writing a review like this. Began talking to treat some pain in one of my feet. Much to my amazement, it worked almost immediately.

Also experienced a sense of well being from time to time. Now on my second bottle and have recommended the product to others.

HELPS for the aches and pains of us guys in their 60's.

Good. Helped me reduce my pain level.

Douglas M. | February 1, 2017

Hopeful but not sure

I do not know what signs to look for to see if the product is helping me especially since I am taking several new supplements. I take it as prescribed as I believe in the content.

Claire F. | January 28, 2017

Excellent product!

This supplement has really done wonders for me. I use it for pain and inflammation in my knees, hips and ankles brought on from a lot of hiking and it really works. No more Aleve or Advil for me, this stuff does the trick. I recommend it highly!

Brad M. | January 28, 2017

40 year old Gym Rat

Wanted to try something different from fish oil because it seemed to give more pain in the wrists. Started taking ZanthoSyn about three months ago. In the past I would suffer from soreness/inflammation in the joints after heavy lifting and would persist throughout the days. I figured this was something I would have to get used to because i wasn't going to stop lifting heavy, so I started wearing braces on heavy lifting days. There was a 3 month break from the gym before taking ZanthoSyn. I started ZanthSyn and going back to the gym at the same time. I haven't worn any braces and lifting heavier than before, and I haven't felt any pain or soreness like in the past. It's kind of amazing but I'm going to stop taking it for a while to make sure it's not anything else and will leave another review later.

kevin r. | January 7, 2017

Total pain relief after 10+ years of daily NSAIDS

I'm in my 4th month of Zanthosyn and take 4 caps a day now for a month. For over a decade I have suffered from arthritis in my neck and required 600 mg of Naproxen daily to be able to function. If I missed one day of the Naproxen, I was disabled with intense headache, neck ache and nausea. I would no longer be able to function. I no longer take Naproxen and my neck pain has not returned. What a blessing. I've also lost weight slowly, now 10 pounds lighter. I never want to stop using Zanthosyn!

Wailua B | January 2, 2017

Feedback on ZanthoSyn

I feel its alright. I was taking Bioastin and I really can't tell the difference. Perhaps, if I stop taking it, I may feel the differnce, however, I dont' want to stop it for I may develop some aches and pains. Overall, I feel good.

Katherine K. | January 2, 2017

ZanthoSyn

great product, no fishy aftertaste. Much greater absorption rate for effective use

richard r. | December 26, 2016

too early

only one month of use so can't really see measurable effects yet but certainly hasn't caused me any harm. Maybe feeling a bit more energy and less aches after my 2 mile runs but really need another month to know what is real and what is placebo. Went from one pill to 2 a day a week ago and think I'm feeling more energy from that.

thomas e. | December 22, 2016

great product

I am now a 4 month user of ZanthoSyn. I suffer from osteo-arthritis in both knees and require total knee replacements. I can walk down stairs normally (not one step and a time). I am looking forward to the results at 6 months! And, plan to postpone surgery.

faith l. | December 19, 2016

BioAstin vs. ZanthoSyn

I used BioAstin for over 5 years before switching to ZanthoSyn, and wondered if my experience (which had been good with BioAstin) would be as good. I've had no ill effects whatsoever, and have found that I can take less with comparable benefits.

Jerry H. | December 19, 2016

May take more time for effecacy?

Haven't experience any noticeable improvement yet

John K. | December 16, 2016

ZanthoSyn Works!

ZanthoSyn is an excellent supplement for overall health and well-being. In addition, I am experiencing improvement in my vision and skin condition and a reduction in joint inflammation. I strongly recommend it to all my friends.

Fred J. | November 25, 2016

Possibly Effective

I am not sure if it is working but I continue to take it because I know that it has an essential ingredient. I believe I shall know more in about 2 to 3 months.

Claire F. | November 24, 2016

What this baby boomer needed

I am 60 and have played tennis competitively for over 45 years, half on hard courts. I've also done various martial arts, and have more recently added serious weight training and cardio work 5-6x a week. Having read the medical literature on astaxanthin, I started taking it - I like the complete anti-inflammatory properties with no side effects. When Zanthosyn came out, I switched due to the better bio-availability which makes the cost per absorbed milligram the best around. I am taking two with each meal - important to take with food for best absorption. The results are so good that I bought around 8 bottles to give to friends who are also exceptional athletes. Hopefully those of you who begin using the product will not expect it to reverse years of wear and tear in your body overnight. I look at it as protecting me on a large scale and cellular level. It is good stuff. If people only knew how important inflammation is to so many diseases, I think zanthosyn would be on the kitchen table of every family. I find it sad that just today, a study came out on Celebrex, saying it really is just as safe as ibuprofen and naproxen - saying it is good news for people taking anti-inflammatory medicines. The fine print is that naproxen is linked to gastrointestinal bleeding and ibuprofen is also linked to high blood pressure and kidney problems. I am one who has done my own homework and have not left the decision up to big pharma.

Taking 2a day. . Paresthisiae

Taking 2a day. . Paresthisiae and leg pain disappeared. I am suggesting for selected patients, based on their tendency to favor natural supplements and aversion to pain Medication and .nsaids. I direct to website for info and to order.

Howard K. | November 5, 2016

Hopeful

After several weeks of using ZanthoSyn I decided that it is helping me. As I was experimenting with several new supplements I was not sure which one was effective. So I stopped Turmeric because of side effects and decided that ZanthoSyn did help me with my pain and joints. I did increase it to 2 capsules but went back to 1 because it was affordable that way. I recently started an autoship with your company--1 bottle every 2 months--as it fit my budget.

Now that I've taken Zanthosyn for more than a month, I have noticed improvement. When I get up in the am I am able to move quicker and better!!! I expect that I will feel even better after two months (cross your fingers)

faith l. | October 19, 2016

No changes

So far haven't noticed any improvement using this for knee tendinitis and low back pain

James B. | October 17, 2016

High purity allow higher dose per capsule

The high purity permits a high dose to be in a single capsule. Much better than taking multiple capsules of lower purity, lose dose alternatives. Would have liked it if the web site showed a picture of a capsule to know what I should expect to see in the clear capsule since there is a non-uniform appearance of the contents.

George W. | October 17, 2016

The Power of Synthesis!

My wife and I were both taking another brand of astaxanthin. The idea of an anti-inflammatory with no side effects was almost too good to be true, especially for my wife who suffers from arthritis and doesn't easily tolerate stomach pains and the like. Then I learned that you folks were about to introduce a new form of

Bradley B. | October 12, 2016

Terrific product

This product represents a major breakthrough: They have identified and isolated the relevant anti-inflamatory compounds from the thousands of compounds that exist in "natural" astaxanthin, and therefore increased the bio-availability of the active compounds by 3x-6x. Much better and safer than NSAIDs or other anti-inflamatory products.

Robert R. | October 11, 2016

No real change

Again not a discernible change in my joint pain...

James B. | October 11, 2016

Lowered heart rate. Excellent!

I've been taking one capsule in the morning and one at night. It's only been a month, and my heart rate is at least 10 point lower, and the only change is I am now taking ZanthoSyn. I am going to stop for a week and see what happens. My wife has been taking it and her joint pains have gone away. My wife wants her own bottle. I am upping the monthly bottle subscription to 2 per month. ZanthoSyn is awesome! Love it.

Ian K. | October 10, 2016

Enhances endurance and performance

I've been using Zanthosyn 1 capsule twice a day for about a month. Just finished running a half marathon, finishing time was faster than I've run in years and was 1 in my age category. Use of Zanthosyn was the main variable compared to my usual routine, I'll continue to use as part of my training regimen.

Jon R. | October 8, 2016

Want to know more about all the benefits it has.

The small capsules are easy to swallow. I am treating sciatica with it. I am taking 4 capsules twice a day, at least trying to. But I also use a homeopathic product parallel.

Holger G. | October 5, 2016

ZanthoSyn

Probably better absorption and serum blood levels of astaxanthin compared to the standard formulations. I'm taking ZanthoSyn at slightly less than 50% of the dose of the another widely used formulation and my impression is that I am getting more of an effect. Hopefully Cardax will do more studies comparing the equivalent doses of Astaxanthin with other formulations.

Fred S. | October 4, 2016

I just started using this

I just started using this product 3 days ago not long enough yet to determine any results

Virtual immediate joint pain relief, no kidding! Also, no longer having leg cramps.

I have had persistent pain in my right hip for more than 30 years since injuring myself in a fall. The pain has prevented me from sleeping on my right side. After the first dose of ZanthoSyn, I noticed a difference in the pain and after two weeks have essentially no pain and can sleep on my right side without problems. I've also been bothered by leg cramps almost every morning. Since starting ZanthoSyn, I have had NO leg cramps. Very pleased with the results.
