Astaxanthin Usage

Written by FoundHealth.

Therapeutic Uses

Many health claims for astaxanthin are based on the fact that it is a strong antioxidant. However, in recent years, scientific confidence in the medical benefits of antioxidants has waned; study after gigantic study of antioxidants such as vitamin E and beta-carotene have failed to find the hoped-for benefits.

Other proposed uses of astaxanthin have at least marginal supporting evidence from double-blind studies . In one such study, 30 men with infertility were given either placebo or 16 mg of astaxanthin daily, for a period three months. 1 The results showed possible small benefits on laboratory measures of fertility.

Another study tested astaxanthin combined with the carotenoid lutein as a possible supplement for enhancing recovery from exercise . In this small trial, 20 body-builders were given either placebo or the carotenoid combination for three weeks. 2 Participants then engaged in intense exercise. The results failed to show that use of the astaxanthin/lutein combination reduced muscle soreness or signs of muscle injury.

Weak evidence additionally hints that astaxanthin might reduce blood pressure , help prevent heart disease , lower cholesterol , protect the lens of the eye against cataracts , protect the stomach against ulcers , and reduce risk of macular degeneration . 3 However, for none of these uses (or any other) can astaxanthin yet be remotely called a proven treatment.

Two studies failed to find astaxanthin significantly more effective than placebo for treating stomach irritation in people with dyspepsia (nonspecific stomach pain). 4
