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

  • 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.

  • 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.*

  • 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.*

  • 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.

Clumping

I have been using this product for over 30 yrs & have been very happy with it. However, for the last 4-5 I have ordered it, it has turned clumpy after it was opened. It sticks to the top & makes it very hard to open & close the container. And lately, the B vitamin complex has been doing the same thing. I thought maybe the sugar content was higher in these 2 products. However, upon reading the labels, I found that it's the same as other products in the line.

Response from Customer Service:

Thank you for sharing your honest feedback about Isotonix® Vitamin C. We’re sorry to hear about your experience with clumping, difficulty dissolving, and the taste. Your comments are important to us and we appreciate you taking the time to let us know.

Clumping can sometimes occur when the product is exposed to heat or moisture, as certain ingredients are hygroscopic and readily absorb moisture from their environment, especially during high temperatures or humidity. While we understand this can be inconvenient, please rest assured that it does not affect the efficacy or potency of the product.

Thank you again for your feedback. If you’d like further assistance or have questions about your order, a customer service representative will reach out to you soon.
