Vitamin C, One of the World's Most Popular Vitamins
Vitamin C (ascorbic acid) is one of the most powerful antioxidants and immune-supporting nutrients available today. Vitamin C is a hard-working water-soluble antioxidant that protects the body at a cellular level. It combats oxidative stress in the bloodstream and within cells, helps restore and promote antioxidant levels, like vitamin E, and supports immune response and cardiovascular function.

Frequently Asked Questions
Who needs to supplement with Isotonix Vitamin C Formula?
Anyone over 18 can use Isotonix Vitamin C Formula to add vitamin C to their diet because very few of us get the recommended five servings of fruits and vegetables in our daily diets.
Is it possible to take too much Isotonix Vitamin C Formula?
Ascorbic acid is extremely safe, even at relatively high levels (because most of the excess is excreted in the urine). At high doses (over 1000 milligrams/day), some people can experience gastrointestinal side effects, such as stomach cramps, nausea and diarrhea. It is recommended that you take vitamin C supplements in gradual servings throughout the day to achieve maximum benefits.*
How does Isotonix Vitamin C Formula aid in cardiovascular health?
It helps maintain healthy cholesterol and triglyceride levels, promoting healthy arterial walls and helping maintain normal blood pressure. It helps the body maintain vitamin E levels, which has known benefits for the cardiovascular system. Finally, vitamin C supports normal platelet activity.*
What is the best way to store this product?
Keep Isotonix in a dry, cool place. If Isotonix are stored in the kitchen, keep them away from the stove, sink, any heat-generating appliances or window ledges. If you live in a very humid area, you may store Isotonix products in the refrigerator, but not in the fruit and vegetables area.

Dear Valued Customer,
Thank you for your valuable feedback regarding Isotonix® Vitamin C! We appreciate your input. It's worth noting that Isotonix products may occasionally clump when exposed to moisture and heat. While this clumping doesn't compromise the product's potency or effectiveness, this can make it more difficult to use. We would recommend storing the Isotonix® Vitamin C in the refrigerator to help reduce this from happening.
Thank you again!
