Overview
O Nature Ziran Astaxanthin Supplements deliver 24 mg of astaxanthin per softgel in a 120-count bottle sized as a 4 month supply. Astaxanthin is a carotenoid antioxidant, and this listing positions it for eye, joint and skin support.
At 24 mg per softgel, this sits well above the more common 4 to 12 mg astaxanthin doses found in many supplements, so anyone new to astaxanthin should be aware this is a higher-potency serving. The 120-softgel count divided across a stated 4 month supply implies roughly one softgel a day, which lines up with typical once-daily astaxanthin dosing.
- 24 mg astaxanthin per softgel
- 120 softgels, 4 month supply
- Positioned for eye, joint and skin health
- Fat-soluble softgel format
Who it's for
Suits people looking for a higher-dose astaxanthin softgel for antioxidant, eye, joint or skin support who want a long supply on hand. Less suited to anyone who has not taken astaxanthin before and wants to start at a lower, more common dose before working up.

Performance notes
Astaxanthin is a carotenoid antioxidant found naturally in algae and the seafood that eats it, and it is typically taken as a softgel since it is fat-soluble, which this format matches. The 24 mg dose and once-daily implied serving size set this apart from lower-dose astaxanthin products on the market.
