Overview

Nutricost's astaxanthin softgel provides 4mg per serving in a gluten-free, non-GMO formula. The 120-softgel bottle is sized as a four-month supply at one capsule daily.

Astaxanthin is a less common supplement than fish oil or vitamin D, so the model number and gluten-free labeling here matter more for buyers cross-checking Nutricost's wider catalog. No reviews or seller copy accompany this listing yet.

  • 4mg astaxanthin per softgel
  • 120 softgels, four-month supply
  • Gluten free and non-GMO
  • Unflavored capsule

Who it's for

Aimed at buyers specifically seeking an astaxanthin supplement rather than a general antioxidant blend. Not for anyone needing a multi-ingredient formula in one softgel.
