Pure product.
Verified Purchase
I came across a review stating that this particular spirulina is cyanide-free, which is impossible to control in the wild, unlike cultivated spirulina. The California desert is an isolated, relatively clean place. Thank you for writing this review. I really like the oral disinfectant tablets, as they can be dissolved for a long time. And the results are almost immediate.

A good supplement with a good composition, convenient packaging. No strong taste. I bought it for a detox. I didn't find any traces of it.

Excellent!
Verified Purchase
Good spirulina. There is no taste, it just stains the tongue. I can’t say anything about the benefits. But it is recommended for women over forty.
