What Are The Benefits Of Astaxanthin Powder For Eye Health?

Mar 31, 2022

Astaxanthin powder, extracted from natural haematococcus pluvialis, is a strong product of Xi an Sost Biotech Co,. Ltd. Lutein and zeaxanthin are antioxidants that can be found in eyes. They are well-known nutrients for eye health and have been shown to help prevent age-related macular degeneration and other degenerative conditions. As a stronger antioxidant, has astaxanthin been found in eyes? What are the benefits of astaxanthin for eyes?

Dr Mark Tso in the University of Illinois did a research by testing astaxanthin levels in the eyes of rats. He found no astaxanthin in rat eyes first time, then he retested the rats that had been fed with astaxanthin, and this time, astaxanthin was detected in rat retinas. Mark verified that astaxanthin can cross the blood-brain barrier into the brain, and then it travels through the blood-retina barrier to the retina and macula. After a series of extensive tests, Mark further demonstrated that astaxanthin can protect eyes from light damage, photoreceptor cell damage, nervous ganglion cell damage, neuronal damage and inflammatory damage when it enters the eye.

So how does astaxanthin protect the eyes?

High levels of oxidation can lead to free radicals being abundant in our eyes. A condition called ischemia, which prevents our eyes from getting nutrients and oxygen, is a common cause of increased oxidation in the eyes. Normal enzymatic processes lead to an increase in free radicals and singlet forms of oxygen such as hydrogen peroxide, peroxides and hydroxides in the eye. Free radicals and singlet oxygen will oxidize the polyunsaturated fatty acids in the retina, which will damage the membrane function of the retina, and eventually cause temporary or permanent damage to the retinal cells. Once the retina is damaged, it cannot be repaired. Therefore, astaxanthin, the superior antioxidant, which can penetrate the blood-brain barrier and the blood-retina barrier, can protect the eye from such damage.

That’s not all astaxanthin does!

A double-blind study which focused on the effects of astaxanthin on eye fatigue and visual regulation was done in Japan. After taking 5 mg of astaxanthin extracted from haematococcus pluvialis for four weeks, 46 % of the participants had reduced their eyestrain. By dividing 40 participants into two groups and one group took astaxanthin at a dose of 6 mg per day for four weeks, another group of Japanese clinical studies found the astaxanthin group showed significant improvement in three separate visual parameter values. Other studies have also tested this work and found similar results. It suggests that intake 6 mg of astaxanthin per day for four weeks can relieve eyestrain such as eye soreness, eye dryness, eye fatigue and blurred eyes.

Why astaxanthin can relieve eyestrain?

Clinical trials have shown that astaxanthin improves capillary blood flow in the retina, making blood flow easier. with better blood flow, the lens adjustment is more flexible and simple, which relieves eyestrain and improves the ability of eyes to focus.

As a powerful antioxidant, that’s the benefits astaxanthin powder can do for eyes.
