What is astaxanthin and how may it support skin health?

Astaxanthin is a carotenoid pigment with potent antioxidant properties, reported to be significantly stronger than vitamin E. Clinical studies show oral astaxanthin may reduce UV-induced skin damage, improve skin elasticity, reduce wrinkle depth, and decrease age spots. It works by quenching singlet oxygen and neutralizing free radicals in skin.

What dosage of astaxanthin has been studied for skin benefits?

Clinical trials have used 4–12 mg of astaxanthin per day for skin outcomes. Improvements in skin elasticity, moisture, and wrinkle reduction were observed at 6 mg daily after 6–8 weeks. The most studied form is derived from Haematococcus pluvialis microalgae. It is fat-soluble and should be taken with meals.

What are the potential side effects of astaxanthin?

Astaxanthin is generally well tolerated. At very high doses, it may cause a slight reddish skin pigmentation. Mild digestive discomfort has been reported. As a carotenoid, it may affect blood sugar and blood pressure. There are no known significant drug interactions, but long-term safety studies beyond 12 weeks are limited.
