Prime™ Astaxanthin Cardio & Visual Vitality Formula uses AstaREAL® astaxanthin. With high quality and stability, AstaREAL astaxanthin ranks among the purest and most powerful antioxidants available. AstaREAL uses precision cultivation techniques in state-of the-art facilities, producing only 100 percent natural astaxanthin in a purified, sterile environment. *Prime Astaxanthin Cardio & Visual Vitality Formula delivers a 6 mg serving of this high-grade astaxanthin in a single serving, providing the optimal amount in every pill. This makes Prime Astaxanthin a giant step forward in the longevity revolution through its unequaled ability to combat free radicals at the cellular level. *The power of Prime Astaxanthin to fight free radicals is of critical importance, but it must also be delivered to the body in sufficient amounts to be truly effective. Typical astaxanthin formulations contain only 2-4 mg per serving — an amount which falls short in delivering all possible benefits for the heart, eyes, skin and muscles. Prime Astaxanthin Cardio & Visual Vitality Formula is made exclusively in a 6 mg serving, which is superior for promoting optimal cardiovascular function, supporting healthy vision and skin, blood flow and muscular endurance. * Together, the quantity and the quality delivered by Prime Astaxanthin yields anti-aging benefits second to none.Daily exposure to free radicals — c ontained within the air we breathe and the food we eat — results in ongoing, long-term physical stress. The widespread oxidative stress they cause to all systems of the body is also believed to be a primary contributor to what we call the aging process. Prime Astaxanthin works against free radicals by providing powerful antioxidant defense to help protect the entire body on a cellular level.
