Overview
NOW Foods' Certified Organic Spirulina tablets are formulated at 1000 mg per tablet, described as double strength, and naturally contain beta-carotene, vitamin B-12 and GLA rather than being a synthetically fortified blend.
Spirulina is a blue-green algae valued for its naturally occurring nutrient content, and the organic certification points to how the raw algae was grown rather than an added processing step. The 1000 mg per-tablet dose sits at the higher end for a spirulina tablet, since many spirulina products use lower per-tablet doses and require more tablets per serving.
- Certified Organic Spirulina, 1000 mg double strength per tablet
- Naturally occurring beta-carotene (vitamin A) and B-12
- Contains naturally occurring GLA
- 120 tablets per bottle
Who it's for
People looking for an organic, naturally sourced spirulina supplement at a higher per-tablet dose, valued for its natural beta-carotene, B-12 and GLA content. Not the choice for anyone who prefers spirulina powder mixed into drinks over tablets.
