What makes BioAstin so special?
More BioAstin informationAstaxanthin is a carotenoid, which are pigment colors in nature. Astaxanthin is the red pigment color found in salmon, shrimp, crab and it's even the pink color in flamingos. The astaxanthin in BioAstin is derived from microalgae called Haematococcus pluvialis. It is grown on land in Kona, Hawaii, in controlled, fresh water ponds and contains no fish or shellfish bi-products.

How much BioAstin should I take?
Shop products best for youDosing is flexible based on your own personal antioxidant needs. Starting with 12mg/day helps optimize levels quickly, especially for skin, eyes, joints, exercise recovery, and UV protection. After a month, some people choose to reduce to 4-8 mg/day for maintenance, balancing benefits with cost. However, staying at 12mg is safe, effective, and preferred by many, including our BioAstin scientific team, for full benefits.
