✔️ANTIOXIDANT RICH. To give you an idea of the antioxidant power of Astaxanthin, it is over 500 times stronger than vitamin E, and nearly 6,000 times stronger than vitamin C. Astaxanthin is a natural carotenoid produced from Haematococcus Pluvialis microalgae, because of its unique structure, provides a wide range of antioxidant benefits for the eyes, skin and brain.
✔️OPTIMAL 7MG DOSE OF PURE ASTAXANTHIN PER CAPSULE, NOT WEAK 5% OIL. Many oil based astaxanthin supplements contain very small amount of astaxanthin blended with oil, typically providing less than 1mg of astaxanthin per capsule, our capsules contain 7mg pure astaxanthin. At Time Health we always keep up to date with new credible research on the products we supply. Top scientific supplement website Examine now suggests that taking between 6mg to 8mg of Astaxanthin per day is the optimal dose.
