Astaxanthin is a naturally occurring keto-carotenoid found in various species, including certain bacteria and microalgae¹. It is recognized for its strong antioxidant properties and has demonstrated multiple health benefits, especially in skin health and cardiovascular protection¹².

Key benefits of astaxanthin include:

1. Antioxidant and Skin Health: Astaxanthin exhibits powerful antioxidant effects, providing photoprotective, DNA repair, and anti-inflammatory benefits. It has been shown to improve skin texture, reduce wrinkles, and enhance moisture content. Additionally, it helps protect skin against UV-induced damage³⁴.

2. Cardiovascular Health: Astaxanthin can help lower cholesterol levels and reduce markers of cardiovascular risk, particularly in individuals with conditions like prediabetes and dyslipidemia².

3. Neurological Protection: Due to its ability to cross the blood-brain barrier, astaxanthin may offer protective effects against various neurological disorders, including Alzheimer's disease, Parkinson's disease, and other traumatic brain injuries. Its antioxidative, anti-inflammatory, and anti-apoptotic properties contribute to its potential neuroprotective abilities⁵.

These benefits make astaxanthin an attractive supplement option in various nutraceutical and cosmeceutical applications, though many studies recommend a dosage range of 3 to 6 mg per day for effective results³⁴.
