The two important factors when searching for quality nutritional supplements are absorption and benefits. Isotonix supplements, when mixed with water, have similar osmotic pressure as the body’s fluids, such as tears, plasma and blood. Isotonix Vitamin C can provide absorption and delivery of the nutrients within the product in an efficient way.

Individual response varies.



Vitamin C
The best food sources of vitamin C include all citrus fruits (oranges, grapefruit, lemons and tangerines), strawberries, tomatoes, broccoli, Brussels sprouts, peppers and cantaloupe. Vitamin C is a "fragile" vitamin and can be easily destroyed by cooking or exposure to oxygen.

Vitamin C is a cofactor or helper in the metabolism of some amino acids and hormones. It is a co-factor in the synthesis of collagen and helps support newly forming collagen. Vitamin C supports cardiovascular health and the immune system. Some of Vitamin C’s benefits appear to be due to its antioxidant properties. Vitamin C also plays a role in maintaining healthy connective tissues, including collagen.

Vitamin C is necessary for humans as humans are incapable of producing vitamin C in their bodies. Vitamin C is known for its antioxidant properties. Since it is water-soluble, vitamin C is flushed from the body each day. As humans may not always eat foods containing an adequate amount of vitamin C, taking a supplement can help in supplementing diet.

Beta Carotene (Vitamin A Precursor)

Vitamin A is a fat-soluble vitamin that is part of a family of compounds including retinol, retinal and beta-carotene. Beta-carotene is also known as pro-vitamin A because it can be converted into vitamin A. Vitamin A helps to maintain healthy eyes and immune system.

Foods rich in potassium include fresh vegetables and fruits, such as bananas, oranges, cantaloupe, avocado, raw spinach, cabbage and celery. Potassium is an essential mineral that helps to keep fluid balance. It also plays a role in a wide variety of biochemical and physiological processes. It supports nerve and muscles health.
