Overview
NOW Foods Astaxanthin 4 mg uses the branded Zanthin astaxanthin source in a 60-count veg softgel formula positioned to support eye health, suitable for vegan and vegetarian diets.
Astaxanthin is a carotenoid antioxidant most often associated with eye and skin support claims, and NOW ties this formula to its Zanthin-branded source rather than a generic extract. The listing's own supplement-type field says multivitamin, which does not match the title or ingredient, so that detail looks like a data mismatch and is not something to rely on when comparing products.
- 4 mg astaxanthin dose
- Zanthin branded source
- Vegan/vegetarian softgels
- Eye health focus
Who it's for
Fits anyone specifically looking for an astaxanthin supplement, particularly vegans or vegetarians since the softgels are labeled for both diets. Not for anyone wanting a general multivitamin, despite what a stray spec field on this listing suggests, since the product itself is a single-ingredient astaxanthin softgel.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4 mg Zanthin-brand astaxanthin per softgel
- Vegan and vegetarian formula
- 60-count bottle is a shorter supply
- Listing's own spec data mislabels the supplement type
Performance notes
Each softgel delivers 4 milligrams of astaxanthin from the Zanthin source, formulated as vegan and vegetarian softgels rather than gelatin capsules. The 60-count bottle sets the pace for how long a single-daily routine would last before reordering.
