Researchers have developed a form of Spirulina that contains biologically active vitamin B12 at levels similar to beef, addressing a significant nutritional gap in plant-based diets.

By manipulating the light conditions during cultivation, they enhanced the algae's ability to produce usable forms of B12, overcoming a key limitation of traditional Spirulina.

This breakthrough offers a sustainable and carbon-neutral alternative for essential vitamin intake, potentially benefiting millions globally who rely on plant-based foods.
