Photosynthetically Controlled Spirulina Products With Enhanced Content And/Or Bioavailability Of Unopposed, Active Vitamin B12

Abstract: Spirulina products, biomass, extracts, various food products, nutritional supplements, and methods of preparing and using the spirulina products are provided. The spirulina products are prepared from Arthrospira spp. biomass that is cultivated under controlled, ultra-high- density conditions with strong UV illumination and strong continuous mixing. The spirulina products may be made of the algal biomass and/or wet/dry extracts thereof, and are characterized by high levels of unopposed B12, providing more bioavailable B12 than pseudo-B12. Spirulina products may have more bioavailable B12 than pseudo-B12 (e.g., at least two or three times more bioavailable B12 than pseudo-B12, and up to thousands of times more), providing a large portion of the required daily B12 intake in a broad range of food products.
