Overview
Astaxanthin softgels from Nutricost at 6mg per softgel, 120 softgels per bottle, labeled a 4 month supply, non-GMO and gluten free.
Astaxanthin is a carotenoid antioxidant typically taken as a softgel since it is fat soluble, and the 6mg dose here sits toward the higher end of common astaxanthin serving sizes. The 4 month supply framing, roughly one softgel a day, makes this a lower frequency reorder than many daily supplements.
- 6mg astaxanthin per softgel
- 120 softgels, a 4 month supply
- Non-GMO
- Gluten free
Who it's for
Suits buyers who want a straightforward, single ingredient astaxanthin softgel at a defined dose rather than a blended antioxidant formula. Not for anyone wanting astaxanthin bundled with other antioxidants in one softgel.
Strengths and trade-offs
Drawn from this product's published specifications.
- 6mg astaxanthin per softgel
- 120 count bottle sized as a 4 month supply
- Gluten free, non-GMO
- Single ingredient formula, no added absorption boosters mentioned
- 4 month framing assumes one softgel daily, which may not match every buyer's intended dose
Performance notes
Astaxanthin is fat soluble, which is why it is packaged as a softgel rather than a tablet; taking it alongside a meal containing some fat is the common approach for absorption, though this listing does not spell out that instruction itself.
