Mostly yes: Spirulina and chlorella from good sources can be very good for your health. Always find out the source. Try to get products from companies that are willing to show testing results of purity. Never buy products from china (some may be ok but there is a lot of contamination).

Supplement store: These are dried algae promoted as "detoxifying agents." for example, supposedly they remove heavy metals from the body and even destroy polychlorinated biphenyls, as reported in one journal of which i'd never heard. Claims that sound much too good to be true almost always turn out not to be true, but of course the decision is yours.

Unclear: Rich in protein, vitamins, minerals, and antioxidants that may help protect cells from damage. It contains b complex vitamins, beta-carotene, vitamin e, manganese, zinc, copper, iron, selenium, and gamma linolenic acid. Can be contaminated with toxic substances called microcystins and absorb heavy metals from water source. Yet, no studies definitively proving health benefits so best to avoid.

Can someone with renal failure have spirulina?

May be helpful but..: Little research has been done on this. Studies on rats suggest that spirulina protects kidneys from various toxins such as mercury & the drug cisplatin. On the other hand, there is evidence that spirulina can sometimes worsen autoimmune disease, so one should be cautious if the cause is autoimmune. There are other useful supplements for renal failure including cordyceps and coq10. See comments:.

None: Spirulina is a dietary supplement that has no legitimate studies showing that it is of value in people with thyroid disease.

No: This is a supplement and it is not essential to maintaining health. It is little used so why is it essential.
