Overview
Nutricost isolates astaxanthin into a single 12mg softgel, packaged 120 to a bottle for roughly a four-month supply. Gluten-free and non-GMO, it suits anyone adding this specific antioxidant carotenoid to their routine rather than getting it through a multivitamin blend.
Astaxanthin is the sole ingredient here rather than one item in a broader antioxidant blend, so the dose per softgel is easy to track. At 120 softgels for a listed four-month supply, the count works out to roughly one softgel a day. The capsule is unflavored, standard for a softgel meant to be swallowed whole.
- 12mg astaxanthin per softgel
- 120 softgels, about a 4-month supply
- Gluten-free, non-GMO
- Single-ingredient antioxidant formula
Who it's for
Suited to people who specifically want astaxanthin at a set 12mg dose and prefer not to guess at the amount buried in a multi-ingredient antioxidant blend. Not the pick for someone wanting several antioxidants combined in one pill.
