Doses typically range from 2- 12 milligrams per day for two weeks to six months. BioAstin® has been used for carpal tunnel syndrome, rheumatoid arthritis, musculoskeletal injury, and sunburn. For male infertility, 16 milligrams (AstaCarox®) by mouth daily for three months has been used. No dose has been proven safe or effective.
Various seafoods contain the astaxanthin pigment. A standard serving portion of 4 ounces of Atlantic salmon contains from 0.5- 1.1 milligrams of astaxanthin, whereas the same amount of sockeye salmon may contain 4.5 milligrams of astaxanthin.
Children (younger than 18 years)
There is currently a lack of available scientific evidence to recommend the use of astaxanthin in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with a known allergy or hypersensitivity to astaxanthin or related carotenoids, including canthaxanthin, or hypersensitivity to an astaxanthin algal source, such as Haematococcus pluvialis.
Side Effects and Warnings
According to the Code of Federal Regulations, astaxanthin is generally recognized as safe (GRAS) when used as a color additive in salmon foods. Astaxanthin is likely safe when used as an antioxidant and as adjunctive support in cancer treatment, cardiovascular disease treatment and ocular (eye) health promotion.
Side effects of astaxanthin use may include decreased blood pressure, increased skin pigmentation and hair growth, hormonal changes, lowered calcium levels in the blood, altered blood counts, decreased libido, and enlargement of the breasts (in men).
Astaxanthin should be used cautiously in patients with hypertension (high blood pressure), asthma, parathyroid disorders, or osteoporosis. Avoid use in patients with known allergies to astaxanthin, hormone- sensitive conditions or immune disorders.
