Vegan and vegetarian diets

Seagreens® are also a natural source of the B-vitamin group including bioavailable vitamin B12. Recent research using the Lactobacillus delbruekii microbiological assay method clarified the bioavailablity of algal vitamin B12, where true vitamin B12 was found to be the predominant cobalamide.

Feeding the algæ to B12-deficient rats significantly improved their vitamin B12 status. The results suggest that algal vitamin B12 is a bioavailable source for mammals, of special value to vegans and vegetarians because the normal dietary sources of B12 are fish, meat and dairy products.

In spirulina the pseudovitamin B12 predominated. This is an inactive corrinoid and is not suitable for use as a vitamin B12 source (91). Seagreens® also improves the metabolism and absorption of all the dietary nutrients on a daily basis, especially where malabsorption is a result of gut dysbiosis or nutritional imbalance (1, 81).

Seagreens® has a significantly more balanced and complete nutritional profile than other algæ particularly kelp as well as the green and red seaweeds.
