Spirulina I know for 9 years now, rich in protein, iron and beta carotene, normally it is 100% natural with no pesticides at least in this one I trust. Spirulina has a cleansing and protective role of the agency is involved in immune function of the body. Also, touts the years from October I make a course of 3 months.
The first 2 days I take 1 tablet / day then the third and fourth day 2 tablets / day, then every 2 days a tablet and more. Personally for me the desired dose is 6 tablets / day, this does not effect immediately, but after 15 days to see three weeks you start to see the effects especially on fatigue, we feel boosted in great shape, despite the gray weather in the winter ... For small decreases morale, and / or tone, I recommend ;-)
