Spirulina Testimonials from the United States

Note: The testimonials on this website are not intended to imply that Spirulina can cure or prevent any disease, nor are they intended as an aid in diagnosing or treating any disease.

People taking Spirulina report finding relief from arthritis and other painful conditions, seeing improvement in skin conditions, feeling more energetic, losing weight, and generally experiencing an increased sense of well-being.

Here are some excerpts from letters that were sent to the offices of the manufacturer, Cyanotech in Hawaii. While these are not scientific studies, they do show how people feel a difference in their health when using Spirulina.

Arthritic Condition: Reiter's Syndrome

I just wanted to let you know how Spirulina changed my life. Two and a half years ago, when I was 29, I developed a painful arthritic condition known as Reiter's Syndrome. My doctor gave me a prescription drug which only upset my stomach and gave me vertigo. By this time, I was finding it difficult to sleep, let alone walk, and I was forced to quit my job. Then my doctor gave me another prescription drug which brought me some relief during the acute stage. The main drawback, besides its exorbitant price, was that it was very hard on my stomach. I spent the next six months in a state of nausea. I was able to walk short distances but it still hurt like hell.

Then one day a friend gave me some Spirulina; after a few days something wonderful happened – I realized I had no pain. I didn't attribute it to the Spirulina, however – I thought it was a natural occurrence. After a few weeks, I ran out of Spirulina, and sure enough, those nagging aches began to return. After a few painful days, I finally hit myself on the head and said, "It was the Spirulina!"

Since that day, about 6 months ago, I've never been without Spirulina. Not only has my arthritis disappeared, my overall mental and physical state is better. Thanks to Spirulina, I wake up each morning feeling fine and able to do things I was afraid I would never be able to do again. What can I say? Spirulina is the greatest! (M. Simon, Fullerton, CA)

Chronic Fatigue Syndrome

These wonderful tablets gave me back my strength. I suffered from Chronic Fatigue Syndrome. I will never quit taking your tablets. (H. Nowak,Helen, GA)

Energy/Resistance to Illness

I seem to be more energetic. I have better resistance to illness—it boosts my immune system. (Carlene Kreetlove, Mazomani, WI)

Eyesight/Skin/Menstrual Pains

Spirulina in tablets and powder has helped me and my family a lot. My eyesight has recovered from blurred vision. I have very tight sleep. Most of my pimples are gone and my face became more beautiful, not only because of smooth skin, but my eyes sparkle and dark spots around my eyes are gone. My menstruation pains are totally gone also. I feel really better. Thanks to Spirulina and God for such a wonderful discovery. (Ellen Dimabayao, Los Angeles, CA)

Energy/Appetite Suppressant/Mental & Cognitive

I am a Nutritional Health Advisor, Chef, Yoga Practitioner and Teacher, 50 Drummer and Writer. In over ten years of veganism I have tried many brands of Spirulina and Nutrex [Hawaiian] is by far the freshest and most potent form available on the market today. This has been confirmed by many nutritionist and scientist colleagues of mine. As a raw and living foodist, I consume Spirulina almost every day and it is one of my main sources of protein. I will never forget the first time I tried Nutrex Hawaiian Spirulina; I had boundless energy, my appetite decreased and I finally felt like my brain was functioning adequately. This product has increased my mental and cognitive capacities remarkably! If you want to understand what is meant by the statement “we use less than 2% of our brain,” try this product and you will feel yourself accessing the remaining 98%. (Shanti Devi Michal, New York City)

Dark Spots on Face

A couple of months before I started taking Spirulina, my doctor warned me to watch a couple of dark spots on my face. These spots were presumably caused by sun exposure damaging my skin. After my wife saw Spirulina recommended by a news letter, we both added it to our diet. To my delight the spots on my face got smaller and disappeared after just a few months. (Emil Eastburn, Westford, MA)

Leg Pain

I am seventy years of age. At the time [I started taking Spirulina tablets] I was having severe pain in my knees and legs, which became much worse when I would lay down. I couldn't kneel and had difficulty even bending my knees. Now I am able to bend my knees and even do knee bends. I am very happy to say I no longer have the pains in my knees. I am so happy to have discovered these miracle tablets. I feel so much better, not only with my knees and legs, but also in my general health. (N. Behling, Palm Bay, FL)

Internal Haemorrhoids

My husband has internal haemorrhoids and Spirulina has controlled them remarkably. (Paula Cramer, Salt Lake City, UT)

Energy/Mental Acuity/Immune System

I have a higher level of energy and mental acuity. It appears to strengthen my immune system. (Pete Bauer, Mazomani, WI)

Neck Pain

Several years ago, I took [a prescription drug] for severe neck pain. I stopped taking it when my sister told me about Spirulina. I seldom have any discomfort in this area now. [The prescription drug] was not nearly as effective as Spirulina. (N. Hawkins, Indio, CA)

Pre-Menstrual Syndrome/Appetite Suppressant

Nutrex Spirulina [Hawaiian] has been like a miracle cure for the severe PMS symptoms I suffered with for years. It’s helped to ease tension and insomnia. Also it has acted as an appetite suppressant. I am very grateful. Thanks. (Victoria Yiannatsis, Rehoboth Beach, DE)


I am a 63 year old woman, have always been very active, and still have a cleaning service where I do a lot of the work myself. I've known for several years that I have the telltale signs of arthritis, the swollen joints in my fingers and a very tender lump on one of my knuckles. I was beginning to think I would have to give up my business as I was in so much pain, especially in my hands. Also, my ankles made a cracking noise when I walked. A friend of mine told me about Spirulina and I thought, well I might as well give it a try. After taking Spirulina for three weeks, the first thing I noticed was that all the soreness and pain were gone from my hands and that my ankles didn't make a noise when I walked. After my second bottle, I could work eight and ten hours straight and still no pain. I was out of Spirulina after my third bottle and after two weeks the soreness and pain had returned. After starting back on Spirulina, within four days all the swelling and pain are gone. I have more energy and just feel better all over. I've stopped taking all my other vitamins. moning and three at bedtime works best for me. I've recommended Spirulina to several of my friends and family members who are now taking it with positive results. I know for myself I don't want to be without Spirulina again. (A. Walls, Melbourne, FL)


I wish to tell you how much I appreciate the introduction to your Spirulina. I first became aware of the product when I asked a neighbor what her secret was in keeping in such good shape and how she gets so much energy. She told me that she had eaten your Spirulina for one year, and gets the energy from this product. I was at that time in the process of moving, and was afraid, by doing all the work myself, I would hurt myself again, especially my shoulders (bursitis), and back (old age, I guess). I am 59 years old. I started to eat 6 Spirulina tablets daily, two weeks before moving. Needless to say, I got through all with flying colors, experienced strength I had not known for a long time. Thank you for making this product available to me. I feel younger, better, stronger, can work better with more energy. I am recommending your Spirulina to my friends, and for a good deed, I get them started with a first supply. (E. Corderoy, Hilo, HI)

Resistance to Colds/Energy/Pain

I have been taking Spirulina for six months. Mostly six tablets a day, sometimes more. I started taking your Spirulina when I had a painful condition in my right knee from what I thought was arthritis. Within two weeks, I had no pain left. It also gave me so much energy. I have not been hungry between meals. I also noticed that I do not get colds and that during the flu season, even though I was in contact with my family who did have the flu, I did not get it. I know that when I forget to take Spirulina my symptoms returned. I know this natural product is from God. I recommend it to anyone. Thank you. (C.B. Lang, lndiatlantic, FL)


I am 64 years of age and have had a bone density test. They determined I have arthritis in two vertebrae, pelvic bone, and knee joint. I was in so much pain it was hard to walk any distance and had trouble sleeping, as I would wake with severe pain in my entire right leg. When I first heard about Spirulina I did not think it would work but I was willing to give it a try. After three weeks, I can now walk two miles without pain. I thank God for Spirulina and for Clara who told me about it. (L. Enmon,Ontario, Canada)


I feel better in the mornings and have more stamina and energy. (D. Waki, Wailuku, HI)

Spirulina Testimonials from Around the World


I have a 7:30 to 5 PM job. When I come home I still do my household chores, and still have time to spend with my three children aged 22, 19 and 17. Thanks to Spirulina I have so much more patience from not feeling exhausted anymore. I feel wonderful, energized, I feel l can handle anything; I just take four tablets in the morning and four in the afternoon. If it can help me in my serious condition, I am sure it can help others with all their complaints. Once again thank you Spirulina by Marcus Rohrer [Hawaiian]. (Mrs. Latiff, Johannesburg, South Africa)

Sports Training

I use Spirulina simply because it works and it is 100% natural. I feel fitter, have a better resistance and recover more quickly after exertion, whether it is a heavy training session or a match. My last condition test showed clearly that I had more stamina than last year. (Erwin Koeman, Dutch National Soccer Team, Holland)


Over the past year I have been taking Hawaiian Spirulina to neutralize ome serious health problems. About four years ago I contracted acute and aggressive Ulcerative Colitis, necessitating the complete removal of my large intestine. In my particular case, this played havoc with my digestive system, especially in the area of essential nutrients. During these last four years I have tried many health products and supplements and have had few permanent benefits. Most of these products helped for a short term, but were unable to sustain that on a continuing basis. Since discovering Hawaiian Spirulina, I have appreciated its benefits over an entire year. Its effects have not diminished, and I have found this to be a major source of my nutritional intake. Since taking Hawaiian Spirulina, I have felt myself being able to increase my energy levels and feel it has helped in my general lifestyle. (Marie Cleanthous, St. Georges, South Australia)

Feel Younger/Hair, Skin and Nails

I am 78 years of age and have been on Spirulina for over a year and find it highly beneficial. Since being on Marcus Rohrer Spirulina [Hawaiian], I have had no flu, my hair has stopped falling out and it is shiny and healthy. My nails are not cracking and they are healthy. My complexion, which was sallow, has become radiant. The tablets are pleasant to take. I am very active with lots of energy and feel like a man 20 years younger. I feel that this is largely due to Spirulina and I can highly recommend it. Thank you Spirulina! (Bob Lipman, Cape Town, South Africa)

Recovery from Operation

Last year I had to have a back operation. A big operation at my age, because at 62 you are not young any more. My surgeon advised me to take Marcus Rohrer Spirulina [Hawaiian] to help me get my strength back quickly. I must say – it was a golden tip! (Mr. Verheyen, Lille, Belgium)

Zest for Life

It was six months ago that my husband and I started taking the little green pills every morning, while the ongoing reaction from friends included remarks like “It’s psychological” – “It’s all in the mind” – “Impossible” – imagination." Now, these same friends are also experiencing the same zest for life thanks to Spirulina Marcus Rohrer (S. Kotze, Kraaifontein, South Africa)

“Physical Enrichment Without Being Rich”

Weight Loss

Taking Spirulina by Marcus Rohrer, I easily managed to lose 15 pounds and I feel a lot fitter. I have a busy job as a representative and often felt tired and was overweight. I had tried everything, also homeopathic remedies, but nothing helped. I will certainly continue to use Spirulina. (Mrs. Van Arendonk, Haarlem, The Netherlands)

Spirulina Worked a Miracle for Me

I am an 83-year old lady living in my own in a flat. Last year I landed up in hospital after I fell one night and became very ill with bronchitis. When I was discharged I was very weak and frail. I was able to shuffle around with the aid of two crutches and only with extreme difficulty; I was so weak I wished that I would die. My daughter-in-law works in a pharmacy and she had heard all about Spirulina by Marcus Rohrer [Hawaiian]. She bought me a little bottle and after a few days I was truly amazed at the change in my condition. I have become more mobile and hardly need to use the crutches anymore. My blood pressure has never been so stable and I am certainly more alert. Several people have remarked on the improvement in my condition and are amazed at the change in me. I can only attribute this to the Spirulina and I want to thank you for this excellent product which has truly worked a miracle for me. (Mrs. Stevens, Durban, South Africa)


I am a national level swimmer currently in the Australian Telstra Dolphins Swim Team. I have been selected in the Australian Under 18 Team that competed in the Sydney Youth Olympics 2001. I have only been using Spirulina for a short time but believe it has helped greatly with training and recovery. It gives me more energy and endurance. I recently swam a 2 km time trial with a 30 second personal best. (David Cox, Beechboro, West Australia)

Sports Training/Energy

I have been taking Marcus Rohrer Spirulina for over four years now. I have been participating in sports since I was 8. At age 12 I was training for football 5 times a week. I have been skateboarding for the past two years and I train very intensively. After being on my board for 5 to 6 hours I can feel every bone and muscle in my body. I then often take almost 20 Spirulina tablets and quickly feel energetic again. Spirulina has helped me a lot: Injuries like bruising and grazes heal really quickly and I am never troubled by growing pains. Before I go to school in the orning I often just drink water and take a handful of Spirulina. That keeps me fit all morning. (Felix Nissen, 14 years old, Aurich, Germany)

Appetite Suppressant/Healing after Operation

I think Spirulina by Marcus Rohrer is the miracle pill in the dark blue bottle. I had to have breast surgery in July and I wanted to be strong and healthy beforehand, so I took 6 pills a day. A week after my operation I had to go back to the plastic surgeon to see how I was healing. Well you would not believe what he said. He said that in all the years he has been in practice he has never seen anyone heal so quickly after an operation. My scars had closed completely and there were no complications. I put it all down to the effects Spirulina had on my body. I never get colds or flu and I have also got my husband on them. He was never a man for pills or vitamins and he swears by them. He tells all his friends about them. Another reason why I use Spirulina is the fact that it actually reduces my appetite the natural way. I seldom feel hungry between meals. (Mrs. J. Joaquim, Durban, South Africa)


I study, work as a photo model and take part in sports often. Combining all this takes a lot of energy. Since I have been taking Spirulina by Marcus Rohrer, I have been able to cope easily with my active lifestyle. To keep my energy level up I started to search for a supplement. Preferably something that was 100% natural. Friends advised me to try Marcus Rohrer Spirulina. A golden tip! You do not notice the effects of Spirulina immediately. You must use it for a couple of weeks. Then you really notice the effects. For 18 months now I have been bursting with energy and can concentrate really well. Also, following a busy day modelling or studying I still have enough energy left to enjoy sport. Spirulina fits in perfectly with my lifestyle: Easy, natural and very effective. Really great! (Charlotte van Zomeren, Amsterdam, Holland)

Chronic Fatigue Syndrome

Hawaiian Spirulina! Have you heard of it? I would like to inform every person out there of this wonderful natural health food that comes in powder or tablet form. Some years ago after running my swimwear shop alone for 13 years, I was completely exhausted and had chronic fatigue syndrome. I had to sell up and take two years out of my life trying to get better. Doctors can do nothing for you. My son had heard about Hawaiian Spirulina and bought some. As each week went by I became stronger and happier and got into life again, my dark hair became shiny again, my nails grew stronger. I SWEAR BY SPIRULINA and have been taking it for 6 years now. I look at the cost as a wonderful way to eat healthy. As I am now 61 years of age and want to always do the most with my life, I will always take Spirulina. I have introduced it to all my family and friends and have watched them all sparkle with health and energy. Why don’t you do yourself a favour also? (Carol Prowse, Holloways Beach, Cairns, Australia)

Olympic Swimmer

Spirulina gave me the recovery between sets to push even harder, improving my focus and boosting my immunity. It enabled me to fulfil the ultimate dream in any sportsman’s life…The Olympics! I am greatly impressed with Spirulina and from my experience there is no equal. Thank you Marcus Rohrer. (Theo Verster, Olympic Swimmer, South Africa)

Spirulina Brings Sunshine into my Life

When I take Marcus Rohrer Spirulina I notice that everything seems to become easier for me. I have more energy and life moves smoothly along. I am more cheerful and feel more optimistic about life.

Spirulina really brings sunshine into my life. (Heidi G, 32 years old, Hoogstaten, Belgium)

Real fitness is not about training – it’s the speed of recovery after exercise that counts and determines one’s level of fitness.

(Nick Bester, professional Ultra Marathon and Triathlon athlete, South Africa)
