Give Your Body the Protection it Deserves
Isotonix® Astaxanthin contains powerful antioxidants that synergistically work to protect both sides of the cell membrane—TWO being fat soluble and the other being water soluble. These three ingredients enhance the power of their partners; together the three can quench a varied number of free radical types while effectively recycling one another for maximum protection.* Unlike many competitors, Isotonix® Astaxanthin is cold water-soluble and in a powdered form, a temperature-controlled extraction that offers a higher concentration of astaxanthin by weight while also dispersing well water without clumping or sticking.

Frequently Asked Questions
What is astaxanthin?
Astaxanthin is a carotenoid that gives the reddish pigment to some algae, salmon, crab, krill and lobster. Isotonix® Astaxanthin Powder Drink Packets uses a fully sustainable source of red pigmented algae. Because it is from algae it allows the Isotonix® Astaxanthin Powder Drink Packets to be suitable for a vegetarian or vegan diet. Astaxanthin is a powerful antioxidant and it does not become a pro-oxidant. This means, even under tremendous oxidative stress, astaxanthin does not create free radicals from itself or its metabolism. Other carotenoids like vitamin A, lycopene and zeaxanthin, on the other hand, may become free radicals when taken in supraphysiologic amounts.
Where is the astaxanthin in Isotonix® Astaxanthin Powder Drink Packets sourced?
This product uses only AstaReal®† Astaxanthin, which is manufactured from carefully cultivated microalgae (Haematococcus pluvialis) in state-of-the-art facilities.
