Overview
NatureBell Maximum Strength Astaxanthin provides 12 mg per softgel, sourced from Haematococcus pluvialis microalgae, in a 240-count bottle sized as a four-month supply.
Astaxanthin from Haematococcus pluvialis is the natural microalgae-derived form typically favored over synthetic versions, and 12 mg is a higher per-softgel dose than many standard astaxanthin products on the market. The 240-count bottle is built around daily single-softgel use over four months rather than a shorter trial size.
- 12 mg astaxanthin per softgel
- Sourced from Haematococcus pluvialis microalgae
- 240 softgels, a 4-month supply
- Non-GMO, gluten free
Who it's for
People wanting a higher-dose, microalgae-sourced astaxanthin for ongoing daily use, particularly for eye health support. Not for someone wanting a lower dose or a smaller trial-size bottle.
