Astaxanthin Supplements May Help Protect Against Skin Deterioration
Repeated exposure to UV radiation can result in premature aging of the skin, including dryness, wrinkles, sagging and loss of elasticity. A recent study suggests that taking an astaxanthin supplement may help protect skin from harmful UV radiation.
Participants in the study included 65 women between the ages of 35 and 60. Over the course of 16 weeks, they were given either 6 mg of astaxanthin, 12 mg of astaxanthin, or a placebo daily. At the beginning of the study, the wrinkle grades on the lower and outer angle eyelids were evaluated by a trained expert. Measurements were performed at week 0, week 8 and week 16.
At the conclusion of the study, the researchers noted a worsening of wrinkles and skin moisture in the placebo group. Both the 6 mg and the 12 mg dose groups did not experience these effects. The placebo and low dose groups also had increases in the pro-inflammatory interleukin-1alpha, but the same increases were not noted in the higher dose group.
Researchers from AstaReal Co. in Japan led the study. It was published in the July 2017 issue of the Journal of Clinical Biochemical Nutrition.
Astaxanthin has been shown to improve eye, skin and joint health and boost cognitive function. If you’re looking to increase your dietary intake of astaxanthin, consider consuming more salmon, rainbow trout, krill, and red-pigmented vegetables and fruits.
