Astaxanthin is a fat-soluble, oxygenated pigment called a xanthophyll and a member of the carotenoid family. It has a unique molecular structure that gives it powerful antioxidant function. It is extracted from salmon, microalgae, and Pfaffia, a yeast. Current research shows that due to astaxanthin’s potent antioxidant activity, it may be beneficial in cardiovascular, immune, anti-inflammatory, and neurodegenerative diseases. Specifically it inhibits lipid peroxidation at the cell level; crosses the blood-brain barrier, effecting treatment of ocular, and neurodegenerative diseases such as glaucoma and Alzheimer's; provides significantly more antioxidant capacity than other carotenoids and antioxidants such as beta-carotene and Vitamin E; entraps free radicals by adding them to its long, double-bonded chain rather than donating an electron; stabilizes the cell membrane like a bridge because its polar end groups span the cell membrane, thus increasing its rigidity and mechanical strength; neutralizes singlet and triplet oxygen (de-charges) generated by UVA and UVB radiation and other sources; binds to a lipoprotein, an efficient transport vehicle, making it more bioavailable; increases immune system function including heightened production of antibody-secreting cells and Interleukin 2 and suppression of Interferon-gamma; inhibits reactive oxygen species that cause inflammation; enhances the antioxidant actions of Vitamin E and Vitamin C and encourages the release of Vitamin A from the liver when needed. Astaxanthin has 100-500 times the antioxidant capacity of Vitamin E and 10 times the antioxidant capacity of beta-carotene. Many laboratory studies also indicate astaxanthin is a stronger antioxidant than lutein, lycopene and tocotrienols. I personally take 3 x 4mg per day.

After few weeks of using this I felt my eyesight dramatically improve. I also feel more energetic overall. Still waiting for the summer to test its effect against sunburn.

This is the first time I have tried this brand. It's much better priced then what I have been ordering and it has the exact ingredients. I will continue to order this brand. Thanks iHerb for caring this product and for your excellent service.

This astaxanthin has helped my eyes, and both my husband and I noticed that we don't get even the slightest sunburn anymore!

...I have been taking this for about two weeks - can't say i've noticed anything but I give 1 tiny drop to each cat (muscle tested FIRST!!) and they are crazy over it. will continue to use for several months to see if it helps.
