Chlorella and Spirulina

January 6, 2010 Written by JP       [Font too small?]

In the world of high fashion models there are certain physical traits that you expect to find in the men and women strutting down the catwalk. But every once in a while an unlikely superstar emerges. These individuals generally don’t possess the typical characteristics found in other “supermodels”. They may be heavier, shorter or just downright “unique” in appearance. A similar phenomenon is found in the field of naturopathic medicine. There are plenty of remedies derived from beautiful sources such as echinacea flowers, lavender buds and milk thistle. However other popular supplements are extracted from decidedly unattractive reservoirs.

In the eyes of many people, algae such as Chlorella and Spirulina are nothing more than common pond scum. Alternative medicine buffs and research scientists vehemently disagree with that point of view. Both perspectives have a basis in reality. Certain varieties of algae can, in fact, be toxic and virtually all algae have an unpleasant aroma and taste. Naturally, these attributes lend themselves to giving algae a bad reputation. But under a microscope or in the context of medical studies, these very same outcasts are often found to have very promising health promoting features.(1,2,3)

Here’s a bullet point overview of some of the most recent data relating to both of these blue-green supermodels:

  • Chlorella and Pregnancy - A group of 70 women with pregnancy anemia and pregnancy induced hypertension (PIH) were given either 6 grams/daily of Chlorella or a placebo from the 12th week of gestation until delivery. Those receiving the Chlorella supplements demonstrated improvements in anemia in their second and third trimesters – as measured by hemoglobin levels. Two key signs of pregnancy induced hypertension (edema and proteinuria) also declined in the Chlorella users during the third trimester. The Japanese scientists conducting the trial noted that Chlorella contains organic sources of folic acid, iron and Vitamin B12 which probably contributed to some of the health benefits exhibited in this study. (4)
  • Chlorella and Smokers - A study published in the August 2009 edition of the journal Nutrition examined the effects of Chlorella supplementation in a group of male smokers. A group of participants with ages ranging from 20 to 65 were asked to take 6.3 grams of Chlorella vulgaris or a placebo over the course of 6 weeks. Blood samples were taken pre and post trial. The results of the testing revealed that the Chlorella users showed increased levels of select antioxidants such as Vitamins C (44% higher) and Vitamin E (16% higher). There were also indications of greater systemic antioxidant enzymes (erythrocyte catalase and superoxide dismutase) and a reduction in DNA damage resulting from tobacco use. The researchers concluded that “Chlorella is an important whole-food supplement that should be included as a key component of a healthy diet”. (5)
  • Chlorella and Animal Studies - Several recent animal trials also shed light on potential future applications for Chlorella. An October 2009 study in the journal Neuroscience Letters describes how Chlorella supplementation can decrease age-related oxidative stress and prevent cognitive decline in older mice. That same month, another trial in the Journal of Medicinal Food reports that adding Chlorella to an unhealthy diet “may prevent insulin resistance” in diabetes-prone rats. In addition, a Taiwanese study determined that Chlorella is as effective as milk thistle in protecting the liver of lab rats against chemically induced damage. This is noteworthy because milk thistle is considered the number one natural remedy for supporting liver health. (6,7,8)
  • Spirulina and Athletic Performance - Adding 6 grams daily of Spirulina to the diets of “moderately trained males” for 4 weeks was shown to improve exercise performance and stamina, increase fat burning and systemic antioxidant levels (glutathione/GSH) and reduce exercise induced oxidative stress (lipid peroxidation). (9)
  • Spirulina + Chlorella and Heavy Metals - A new experiment conducted at the Department of Pharmacology at the Mymensingh Medical College in Bangladesh discovered that Spirulina extracts can effectively remove arsenic from the livers of mice suffering from arsenic poisoning (arsenicosis). In September 2009, a group of Japanese researchers also reported that Chlorella could “contribute to the prevention of gastrointestinal absorption of lead and the promotion of the excretion of lead” in mice. In many parts of the world, heavy metal exposure is a leading cause of developmental disorders and illness. Medicinal algae may be a safe and viable strategy to mitigate such a risk in regions where arsenic or lead exposure is common. (10,11)
  • Spirulina and Diabetes - 30 days worth of Spirulina supplementation provoked positive changes in diabetic rats according to an Indian study from Pondicherry University in Kalapet. Improvements in blood glucose, body weight, insulin and pancreatic health were noted. Yet another Indian trial determined that combining Spirulina with a common anti-diabetic medication (Rosiglitazone or Avandia) could reduce the risk of drug related bone loss in a group of insulin resistant rats. The authors theorized that the calcium and phosphorous in Spirulina may account for the bone strengthening effect noted. I would personally add that Vitamin K and Vitamin K2 may also be at work here. In addition, improvements in “fasting serum glucose, HDL, LDL and triglycerides” were found in the rats receiving the Spirulina/drug combination. (12,13)
Spirulina May Improve Athletic Performance
Source: Medicine & Science in Sports & Exercise: January 2010 (a)

While searching through the scientific literature I wasn’t surprised to find numerous studies emanating from Asian countries such as China, Japan and Korea. But what I found particularly interesting was the rather impressive number of algae experiments conducted in India. I simply wasn’t aware of the commercial or traditional use of therapeutic algae in that country. Apparently, I wasn’t the only one who was taken aback by this news. A scientific review of traditional Indian plants in the September 2009 edition of the Journal of Ethnopharmacology includes Chlorella vulgaris in it’s evaluation of this topic. The authors describe Chlorella and 12 plant species as “reported for the first time for the treatment of inflammation related diseases” in the Indian healing tradition. (14)

Future prospects also look particularly bright for medicinal algae. An eye drop consisting of an extract of Spirulina platensis is currently being evaluated for corneal diseases of the eye such as macular degeneration. Preliminary evidence suggests that this natural eye drop may one day offer a more affordable and safer option to currently available drugs including Avastin and Lucentis. (15)

The human studies I’ve referenced today have utilized encapsulated or tableted forms of Chlorella and Spirulina. Both algae have a somewhat aquatic flavor and odor. Therefore, most people prefer swallowing a handful of algae pills rather than sprinkling it into their morning cereal or yogurt. However, it is often possible to mask the taste quite well in a protein shake or smoothie. At the moment, I’m taking a “green food” supplement that comes in a capsule form. In the past I have also used a mixed greens formula that provided both Chlorella and Spirulina in a delicious powder form – no joke! This is one type of supplement that can largely be influenced by your taste. If you have a sensitive palate, I would suggest opting for capsules, tablets or naturally flavored powdered forms. Be sure to choose a form that suits your needs. If you can’t stand the taste, it’s unlikely that you’ll take it consistently.

Be well!

    Morning JP,

    nice topic. on my desk lie a few product samples of chlorella and spirulina. i read that some dentists use those to detox after a amalgam filling removal (toghether with cilantro and wild ramsons or wild garlic). the producer is greenvalley (thats the brand, they produce in japan, india and usa all organic). i read on a few sites that algae can also remove radioactive minerals off the body like uranium from water and therefore clean the kidneys and the liver, cleanse from mercury and lead and so on.

    hubby and i lived 3 years in bavaria and drinking water there is often contaminated with uranium – very high levels. for bottlet water theres a limit of 2 mcg/l but the drinking water out of the water tap contains there in some places more than 18-32 mcg/l! bad for babys! i didn’t know that for a long time :-( so i think im contaminated ;-)

    the only bad thing about algae is that their vitamin b12 is an analog to the form that our body can use. so if taken to much from algae our vitamin b12 receptors are blocked with a for us non working vitamin b12. thats a little bit a problem. read about vegetarian ladies which had supplemented during pregnancy with algae and their offsprings are handicapped because of vitamin b12 deficiency. this point should be considered.

    however beyond that is a good way to alkalize blood and detox and clean body (my opinion :-) ) so for now i have to overcome the taste and try my samples ;-)

    bon appetite!

    Dear JP,
    You have made all these complex information so easy to understand for the reader. Your work and rasearch are wonderful. Thanks for created a wonderful health resource center.

  3. JP Says:

    Good day, Nina! :)

    I’ve also been in contact with some alt-med doctors who include chlorella to manage established or suspected heavy metal exposure (mercury is often cited).

    I’m sorry to hear of the contaminated water in your home land. It seems none of us can entirely escape one type of health hazard or another. The best we can do is avoid what we can and protect against any unknown insults via diet, lifestyle and the judicious use of supplements. Apart from that, we can keep our fingers crossed or pray! :)

    Your point about Vitamin B12 is a good one. In fact, I wouldn’t take algae along with most other supplements. Taking Chlorella and Spirulina on an empty stomach may be best for this reason (B12) and others such as it’s ability to bind to metals.

    I hope the taste of your sample supplements is better than you imagine! Good luck! :)

    Be well!

    Hi JP! Happy new year! A great article on the wonders of pond scum! I am also hoping that algae may prove to be valuable as an energy source one day, but I guess that is another topic :)

    As always, I must stress the importance of taking a QUALITY greens supplement. Beware the powered greens “miracle” packets at the grocery checkout! They may taste delicious but most of the time contain very little nutrients that can be readily absorbed by the body.

    Best wishes, Bill

  6. JP Says:

    Happy New Year, Bill! :)

    I’m not sure if algae will ever come into it’s own with regard to global energy but I think it can play a role presently in individual energy! ;)

    We agree that quality is important when considering “greens” or any supplement. It’s not just what you put in your body but also what impurities you keep out of it. Low quality algae supplements that lack purity and that include lots of fillers and questionable ingredients should definitely be avoided. Thank you for pointing out that important factor!

    Be well!

    Hello JP!

    I am having the amazing grass superfood which has both these algae as a bed-time drink as i see your well written and researched article.I also wanted to ask your thoughts on carb blockers and their effect on blood sugar! Since having this superfood my uric acid levels (which is always in 8 or 9 range has come to 7.8 and getting better. Thanks again for all your useful and informative postings.

    Best Regards

    Sai

  8. JP Says:

    Good day, Sai! :)

    I’m thrilled to hear about the decline in your uric acid levels.

    re: starch blockers

    Do you eat many carbs in your daily diet? The reason I ask is because alpha amylase inhibitors (such as white kidney bean extract) are mainly/possibly effective in diets rich in carbohydrates.

    Please check out this abstract:

    http://www.ncbi.nlm.nih.gov/pubmed/17658120

    Some studies have found reasonably positive results:

    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1796956/?tool=pubmed

    The latest study isn’t very promising though – based on the typical dosage used:

    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2776021/?tool=pubmed

    More studies can be found via the manufacturer’s web site (all PDF files): http://www.phase2info.com/clinical-studies

    Bottomline: I suspect that this variety of supplement wouldn’t be very useful … unless your diet is higher in carbs. If it is, I think it would be worth trying.

    PS – I’m beginning to see a new variety of supplements containing sucrase inhibitors (such as L-arabinose) on the market. I’ve yet to see any clinical studies that support their use. Hopefully some evidence will come to light soon.

    I hope this helps!

    Be well!

    I was only able to find animal studies re: spirulina and pregnancy:

    “Spirulina appears to be effective in improving the iron status of rats during pregnancy and lactation.”

    http://www.springerlink.com/content/n8117726156t658u/

    “Treatment was not associated with any adverse effect on any measure of reproductive performance, including male and female fertility and duration of gestation.

    Please tell me what brand has the best quality of chlorella. Thank you..

  14. JP Says:

    Silvia,

    There are quite a few high quality brands currently available. Here are a few I’d personally consider:

    Chlorenergy Chlorella

    Sun Chlorella

    Swanson Vitamins Kyoto Chlorella

    Yaeyama Chlorella (contained in several brands such as Jarrow Formulas and Source Naturals)

    I hope this helps!

  15. Morgan Says:

    Please explain again about B12 analogues. Does this mean that B12 from other sources (eg red meant) will also not get taken up or is it just the B12 from the chlorella?

    I am an athlete and B12 uptake is crucial for me. If chlorella reduces or prevents B12 uptake, I should stop taking it!

    Thanks.

  16. JP Says:

    Morgan,

    What’s important to understand is that some foods such as chlorella and red meat contain “true Vitamin B12″. On the other hand, spirulina mostly contains “psuedo-Vitamin B12″ which isn’t active in animals and humans. Only the former satisfies Vitamin B12 requirements in the body.

    http://www.ncbi.nlm.nih.gov/pubmed/12656203

    http://www.nrjournal.com/article/S0271-5317%2810%2900099-0/abstract

    Be well!

    JP

  17. Morgan Says:

    Thank you very much, JP. I understand that you are saying that chlorella is better than spirulina for B12, but my question is, having read that chlorella may contain B12 analogues, which block the uptake of B12, do people taking chlorella run the risk of failing to take up B12, whatever the B12 source may be? Thank you.

  18. JP Says:

    Morgan,

    The first link in my last reply explains that chlorella primarily contains “true Vitamin B12″. B12 analogues are also referred to as “psuedo Vitamin B12″. Spirulina is rich in this form of B12 but chlorella is not.

    One of the studies I cited in this columns suggests that chlorella is unlikely to interfere with B12 uptake. In fact, the pregnant women in the study showed improvements in anemia and hemoglobin status. Vitamin B12 intake plays a positive role in managing anemia and the production of hemoglobin.

    http://www.springerlink.com/content/671736k33wj23008/

    I personally wouldn’t be concerned about chlorella affecting my B12 status in a negative manner.

    Be well!

    Always enjoy reading your blog and I appreciate all the valuable information in an easy to read format.

    I bought some Now Chlorella a long time ago, and had some bad side effects even with only a half teaspoon dose. The first time I used it, I had nausea, chills, sweats and ran a low grade fever.

    After leaving it alone for a long time, I took it again and experienced just nausea. Now I’ve lowered my dose to around 1/4 tsp. and have no bad effects. I plan to use this daily, along with a Kelp supplement a few times per week.

    Thanks for everything you do, keep up the great work :)

  20. JP Says:

    Thank you, K2C!

    It sure sounds like dosage is the issue. When I’ve used chlorella in the past, I’ve always opted for the capsules or tablets. The powders are a better deal and contain fewer added ingredients (binding & flowing agents, gelatin, etc.) but I found the taste of both chlorella and spirulina to be unappealing.

    I’m happy you’ve found a way to use the chlorella that suits your body well. I hope you find very positive results with it!

    Be well!

    Thank you for your blog.

    I was wandering if chlorella and spirulina would help me with my thinning hair.I am on a protein diet and I think that’s the cause of my hair problem. Thank you.Regards.
    L.

  22. JP Says:

    Lidka,

    If I were you, I would try to determine what nutrients you may be missing in your diet. Hair loss associated with restrictive diets can often be remedied by the judicious use of supplements and/or eating specific foods that address (nutrient) deficiencies. I would look into that first before relying on chlorella and spirulina.

    Be well!

    Gwen,

    In most cases, it’s unnecessary to stop using a multivitamin/mineral while taking supplemental “greens”.

    Hello jp! Should children be takinh chlorella and spirulina and if so at what age should they start?

  26. JP Says:

    Janet,

    I think the majority of children don’t require supplements such as chlorella and spirulina. For the most, kids just need to eat a healthy, whole food-based diet and take an age-appropriate multivitamin/mineral.

  28. JP Says:

    Renee,

    I wish I could give you a definitive response. But there simply isn’t any specific data that I can use to answer that question. The best I can say is that it’s possible that the antioxidants and nutrients in Sun Chlorella will assist with the healing process.

    BTW, I recently updated this column. I included a paragraph (at the end of the column) with some new research that may be of interest:

    Hello JP!

    I’ve been hearing a lot from friends and family about the benefits of chlorella and spirulina, so it aroused my interest and I looked up these products on Amazon and saw a new brand called FEBICO. Do you know anything of this brand? I think this is a company from Taiwan, do you know anything about the quality of their products?

    Thanks for your help on this.

  30. JP Says:

    Hello, Darrin.

    I’m sorry but I’m not familiar with this manufacturer. I’ve visited their website. However it’s difficult to determine quality based on a web site alone.

  31. Rob Says:

    Would you recommend taking chlorells and spirulina together and is it better for them to taken away from other supplements?

  32. JP Says:

    Hi, Rob.

    I wouldn’t hesitate to take chlorella and spirulina together. Ideally, I think they’re best taken with food (a meal or snack) and apart from other supplemental nutrients (multivitamins, etc.).

    Be well!

  33. Sanjay Says:

    Hi JP,
    In one of the discussions, the outcome is suggesting that consuming chlorella alone will not inhibit vit b12 absorption, but having it with spirulina may inhibit the same. Does it not suggest that one should only consume chlorella? My next question is the disparity in the recommended dosage on the net. What is the dosage of both these suppliments
    Sanjay

  34. JP Says:

    Hi, Sanjay.

    Chlorella and spirulina have the own unique attributes. They both possess various health promoting properties, but they’re not exactly interchangeable. In terms of dosage, I would try to stick closely to dosages that have been validated in controlled clinical studies. Also, dose varies based on the condition being addressed. Having said that, a 6 gram/day dosage is frequently cited in the medical literature.

    Be well!

    JP

  35. Sanjay Says:

    Hi JP,

    Thanks for the reply. If I have both spirulina and chlorella, i will get over with the problem of Vit B 12 absorption….is that right? Also 6 gm/ day of both or 3g spirulina and 3 gm chlorella?

    regards,
    Sanjay

  36. JP Says:

    Hi, Sanjay.

    I wouldn’t anticipate any problem with B12 if you used both supplements. Most of the studies have used one supplement or the other – not both combined. That’s what I was referring to when mentioning the 6 gram/day dosage. Exactly what dosage you use ought to be based on your reason for using chlorella and spirulina.

    Be well!

    JP

  37. Sanjay Says:

    Hi JP,

    My problem is that though my body is easily able to absorb spirulina, same is not the case with chlorella. I go into passing plenty of stools whenever i take chlorella this makes me weak. Sticking on to spirulina alone poses the risk of vit b12 deficiency. Could you please advise

    regards
    Sanjay

  38. Sanjay Says:

    Hi JP,

    Is 6 gm per day a combination of spirulina and chlorella or you need to take 6 gm each. Also, I eat lot of poultry in my diet. If I continue to take spirulina alone will i have vit b 12 deficiency.Like i wrote earlier, I cant seem to absorb chlorella well
    regards
    Sanjay

  39. JP Says:

    Hi, Sanjay.

    Some studies have used 6 grams a day of spirulina. I doubt a deficiency would occur if you eat a nutrient dense diet. A high-potency multivitamin can offer additional protection in this regard. However, I think it would be wise to consume spirulina apart from supplements containing B12.

    Be well!

    JP

  40. Sanjay Says:

    Hi JP,

    I am consuming 6 gms of spirulina and 3 gms of chlorella daily. I am not keen on taking Vit B 12 suppliments..Has there been a known case of someone who got into a Vit B 12 deficiency due to spirulina? Another doubt is that I do not feel that hungry now and if I eat the food as much as i used to do earlier, I feel i am bloated…

    regards,
    Sanjay

  41. JP Says:

    Hi, Sanjay.

    I’m not aware of any documented cases in the medical literature. To be on the safe side, I would just try to eat plenty of foods rich in B12 (salmon, sardines, yogurt, etc.) in addition to supplementing with spirulina.

    Based on your previous reply, it may be worthwhile discontinuing the chlorella temporarily to determine if it’s the cause of the bloating. If you decide to reintroduce it at some point, I would consider doing so gradually.

    Be well!

  42. Shabana Says:

    Hi JP,
    I read this report”Superfoods For Optimum Health: Chlorella and Spirulina
    by Mike Adams, the Consumer Wellness Research Center”where he swears by this super food as a cure for almost anything. But reading your blog gave me a slightly different view. I am also a little confused about the dosage issue-Mike Adams says to take 5gms with each meal and it is only half the dosage and since its not a drug or medicine, there is no upper limit to taking it. A GNC shop here has only 500mg caps of only Spirulina.
    Is this available in India and whats the best brand? Any pointers will help me get it from India. Thanks.

    hi,,my father-in-law as been takeing cholera an spirulina to get rid of heavy metals from scans mri ct,gandolinium and others lots scans over the last few years ,my question is is he ok with the b12 uptake , he takes b12 just 2 1000mg tabs, in a week,,main question,,,the spirulina and cholera that he takes is about half a teaspoon of powder a day, 1 drink bedtime 1 drink morning,,i am worried because he does have liver diesease ,,fibrosis,,,caused from a virus,,,which he is a sustained response from treatment for over 6 years, he got damage to his liver they found with biopsy,,,,he as only just started the cholera spirulina,,should i tell him to quit ,,hes on about useing a clay for cleaning also and a cheolator or something sound like that ,,,:::?/???

  44. JP Says:

    Hi, Shabana.

    I’m sorry for the delay in my response. I didn’t see your question until just now.

    I don’t know what evidence Mike is using to make such a recommendation. However, I disagree with the philosophy that all natural foods and supplements are safe no matter what the dosage. This is a generalization that may be hazardous to one’s health, IMO.

    Unfortunately, I’m not familiar with the availability of chlorella and spirulina in India. I know that some US-based, online supplement vendors do ship internationally. Although, I checked two major US sites (IHerb and Vitacost) and they do not appear to deliver to India. Have you tried searching under terms such as, “Where to buy chlorella in India” and “Where to buy spirulina in India”? I know that’s an obvious suggestion. But, it just may be the most practical one as well. :)

    Be well!

  45. JP Says:

    Hi, Shar.

    There is some preliminary evidence that chlorella and spirulina *may* protect the liver under experimental conditions. However, the findings have been mixed – some negative, some positive. Whether or not it’s appropriate for your father-in-law is difficult to say. This is a decision that he should make with his doctor, IMO – who knows all the details about his current health status and medical history.

    Chlorella Update:

    http://www.nutritionj.com/content/pdf/1475-2891-13-57.pdf

    Nutr J. 2014 Jun 11;13(1):57. [Epub ahead of print]

    Impact of daily Chlorella consumption on serum lipid and carotenoid profiles in mildly hypercholesterolemic adults: a double-blinded, randomized, placebo-controlled study.

    Ryu NH, Lim Y, Park JE, Kim J, Kim JY, Kwon SW, Kwon O.

    BACKGROUND:

    High level of serum cholesterol is considered to be a major risk factor for cardiovascular disease (CVD). A double-blinded, randomized, placebo-controlled trial was performed to test the hypothesis that a daily intake of Chlorella may improve serum lipid profile through enhancement of serum carotenoid concentration in mildly hypercholesterolemic subjects.

    METHODS:

    Eligible subjects (n = 63) were randomized to either Chlorella (5 g/day) or placebo for a double-blinded trial with a 2-week lead-in period and a 4-week intervention period. Serum triglycerides, total cholesterol, lipoproteins, apolipoproteins and carotenoids were assessed at the beginning and the end of the trial.

    RESULTS:

    Compared with the control group, the Chlorella group exhibited remarkable changes in total cholesterol (Chlorella -1.6%; placebo 0.03%; P = 0.036), triglycerides (Chlorella -10.3%; placebo 11.9%; P = 0.002), lutein/zeaxanthin (Chlorella 89.6%; placebo -1.7%; P < 0.0001), and alpha-carotene (Chlorella 163.6%; placebo 15%; P < 0.0001). Improvement of serum lipids was supported by significant reductions of very low-density lipoprotein cholesterol (Chlorella -11%; placebo 11.8%; P = 0.006), apolipoprotein B (Chlorella -1.5%; placebo 1.7%; P = 0.044), non high-density lipoprotein (Chlorella -2.6%; placebo -0.5%; P = 0.032), and high-density lipoprotein/triglycerides (Chlorella 4.0%; placebo -9.5%; P = 0.023), suggesting an inhibitory effect of Chlorella on the intestinal absorption of dietary and endogenous lipids. Further, the changes of serum lipids appeared to be associated with the changes of serum carotenoids.

    CONCLUSION:

    Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol, in mildly hypercholesterolemic subjects. The effect was related to carotenoid consumption.

    The Effect of Chlorella vulgaris Supplementation on Liver En-zymes, Serum Glucose and Lipid Profile in Patients with Non-Alcoholic Fatty Liver Disease.

    BACKGROUND:

    Non-alcoholic fatty liver disease (NAFLD) is becoming a public health problem worldwide and using microalgae is a new approach on its treatment. The aim of this study was to investigate the effect of Chlorella vulgaris supplementation on liver enzymes, serum glucose and lipid profile in patients with NAFLD.

    METHODS:

    This double-blind randomized placebo-controlled clinical trial was conducted on 60 NAFLD patients from specialized clinics of Tabriz University of Medical Sciences from December 2011 to July 2012. The subjects were randomly allocated into 2 groups: 1) “intervention” (n=30) received 400 mg/day vitamin E plus four 300 mg tablets of Chlorella vulgaris and, 2) “placebo” (n=30) received 400 mg/day vitamin E and four placebo tablets per day for 8 weeks. Weight, liver enzymes and metabolic factors were assessed in fasting serum and dietary data was collected at baseline and end of the study.

    RESULTS:

    Weight, liver enzymes, fasting blood sugar (FBS) and lipid profile decreased significantly in both groups (P<0.05). The differences in weight, ALP and FBS between the two groups were statistically significant (P=0.01, P=0.04 and P=0.02, respectively).

    CONCLUSION:

    C. vulgaris seems to improve FBS and lipid profile and therefore could be considered as an effective complementary treatment in NAFLD.

    Be well!
