Researchers have produced a form of Spirulina that contains biologically active vitamin B12 at levels comparable to beef by carefully controlling the light as it was grown. Conventional Spirulina mainly contains a form of B12 the human body cannot use. The new system, which is carbon-neutral, could provide a more sustainable source of B12 in the future, say researchers.

The research was published in Discover Food and led by Dr. Asaf Tzachor, Founder and Academic Director of the Aviram Sustainability and Climate Program at Reichman University, together with researchers from Iceland, Denmark and Austria.
