Overview
NOW Foods' Astaxanthin softgels supply 10 mg of extra-strength astaxanthin per softgel, sourced from non-GMO Haematococcus pluvialis microalgae, in a 60-softgel, gluten-free bottle.
Astaxanthin is a carotenoid pigment extracted from microalgae, and this product sits at the higher end of over-the-counter dosing at 10 mg, above the 4-6 mg found in many entry-level astaxanthin products. The listing notes the softgels naturally carry small amounts of lutein, canthaxanthin and beta-carotene alongside the astaxanthin, since these compounds occur together in the source algae.
- 10 mg astaxanthin per softgel
- 60 softgels per bottle
- Sourced from Haematococcus pluvialis microalgae
- Gluten-free, contains soy
Who it's for
Fits buyers who specifically want a higher 10 mg astaxanthin dose rather than a lower-strength starter product, and who are comfortable with a soy-containing softgel. Anyone with a soy allergy needs to check the allergen note before buying.
Strengths and trade-offs

- 10 mg extra-strength dose

Performance notes
At 10 mg, this sits at the higher end of astaxanthin dosing, and the natural presence of lutein, canthaxanthin and beta-carotene reflects the whole-algae source rather than added ingredients.
