As popular eye protection ingredients, which one has more advantages, astaxanthin or bilberry extract?
Bilberry Extract Powder: The main raw material is Bilberry, which is extracted and purified. It is rich in active substances anthocyanins.
Astaxanthin: A ketocarotenoid, fat-soluble hemoglobin, naturally produced by Haematococcus pluvialis and the yeast Xanthomonas spp.
In terms of the principle of eye protection, the anthocyanins in lingonberry have the function of eye protection. Experiments have shown that anthocyanins have a relaxing effect on ciliary muscles, can promote the regeneration of rhodopsin, and improve night vision; astaxanthin has antioxidant activity, can neutralize oxygen-free radical molecules, and provide protection for the eyes.
Due to the special structure of astaxanthin and the fact that it is a fat-soluble component, it metabolizes slowly in the body and can remain in the body for a longer period of time. Anthocyanins are water-soluble components, generally responsible for removing free radicals in the water environment, and are relatively easy to metabolize.
