Spirulina and cancer:
A study in India evaluated the use of Spirulina at a dose of 1 gram oral daily for one year in the treatment of oral leukoplakia on 44 tobacco chewers. It was determined that complete regression of the condition was seen in 45% of the Spirulina group compared to 7% of the placebo group. (9)
Safety data of Spirulina:
Spirulina supplementation has a promising application in allergic disease (especially allergic rhinitis), treatment of hyperlipidemia, and for use in oral leukoplakia. The information below supports the need to have a pure standardized Spirulina product to be free of microcystins, heavy metals, bacteria, and anatoxin-a. A basic online search by Preventive Health Advisor has not located a Spirulina product which meets these requirements. If a product with these standards is able to be located, it would be the most suitable for use by patients.
