Astaxanthin — Food & Nutrition

What is Astaxanthin?

A carotenoid super-antioxidant more potent than vitamin E

The natural pigment that gives salmon and shrimp their red color, extracted from microalgae. Gaining attention in UV defense and anti-aging skin research.

Characteristics & nutrition facts

Astaxanthin is a red carotenoid produced by the Haematococcus microalga, and it is the natural pigment that gives salmon and shrimp their red color. Because it sits spanning the inside and outside of cell membranes, it is known to respond to oxidative stress in a way different from other carotenoids, and it is frequently mentioned in the context of UV and environmental oxidation. Being fat-soluble, its absorption is influenced by fat.

How to manage

Being fat-soluble, taking it with a meal that includes fat can help with absorption, and it is best to check the labeled content (mg) and the source (whether it is microalgae-derived). Given the nature of the pigment, taking it consistently within the recommended amount is generally recommended, and if you have a seafood or algae allergy, it is best to check the source.

Good to know alongside

It is sometimes compared with other carotenoids such as beta-carotene and lutein, and with vitamin E, in the antioxidant context. In environments with a lot of UV exposure, sunscreen use is recommended as basic.

Everyday care tips

Taking it with an oily meal is favorable for absorption, and apart from supplements, adding salmon and shrimp to your diet can contribute to natural intake.
