Researchers unveil sustainable spirulina solution to vitamin B12 deficiency
Filed by Dr. Iris Vale
Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow the algae, they overcame a major problem with conventional Spirulina, which mainly contains a form of B12 the human body cannot use. The carbon-neutral system could provide a more sustainable source of the essential vitamin.
