AI Insight

Researchers have developed a method to produce Spirulina algae containing biologically active vitamin B12 at concentrations comparable to beef by manipulating the light conditions during cultivation. Conventional Spirulina primarily contains pseudovitamin B12, an analog that humans cannot metabolize effectively. This carbon-neutral production system addresses a significant limitation of plant-based B12 sources.


This breakthrough could provide a sustainable alternative to animal-based vitamin B12 sources, particularly important for vegetarians, vegans, and populations at risk of B12 deficiency. The carbon-neutral production method offers environmental advantages over conventional livestock farming while delivering an essential nutrient that is typically difficult to obtain from non-animal sources.

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.
