Overview
A 60-capsule astaxanthin formula sold as a 30-day supply, marketed for endurance, skin and visual health with heart health support listed as a benefit. It is labeled vegan and unflavored.
Astaxanthin is the active ingredient the title leans on, with the brand describing it as many times more potent than vitamin C as an antioxidant, a comparison specific to astaxanthin's chemical antioxidant activity rather than a claim about overall health outcomes. Buyers should treat that multiplier as the seller's own framing rather than a guaranteed benefit.
- 60 capsules, 30-day supply
- Astaxanthin-based antioxidant formula
- Vegan, unflavored
- Heart health support listed
Who it's for
Fits buyers already interested in astaxanthin specifically for its antioxidant profile, rather than someone new to supplements looking for a general multivitamin.
