The two most important factors when searching for the best quality nutritional supplements are absorption and potency. Isotonix supplements, when mixed with water, have the same pH and osmotic pressure as the body’s fluids, such as tears, plasma and blood. In order for meaningful absorption of nutritional content to take place, all food must be converted into an isotonic state. This process could take up to three hours. This time-consuming process limits the amount of nutrients absorbed by the body. However, our Isotonix Vitamin C Powder Drink sets itself apart from other products on the market providing you with the maximum absorption of the nutrients within the product in the shortest amount of time.  

Isotonix Vitamin C Powder Drink provides superior delivery of the nutrients your body needs in the most effective way. According to researchers at the University of Leeds, Guy’s Hospital in London, Baylor University and the Mayo Clinic, among others, have shown that not only do isotonic solutions leave the stomach faster, but also that the osmotic pressure of the stomach contents is one of the controlling mechanisms for the rate at which the stomach empties leading to more efficient assimilation by all of the body’s systems. Give your immune system the support it needs with Isotonix Vitamin C Powder Drink.

For most of us, it's just not practical to consume the recommended five servings of fruits and vegetables needed on a daily basis to achieve the RDA of 75-90 milligrams of vitamin C from diet alone. Incorporating Isotonix Vitamin C Powder Drink into your daily routine, will ensure you are getting the amount you need. Those who may especially need supplemental vitamin C include the elderly, those with weakened immune systems, smokers, those under heavy amounts of stress, those with cardiovascular conditions and athletes.

Isotonix Delivery System

Isotonix products offer one of the most efficient delivery systems in dietary supplements.  Formulated using scientifically proven ingredients, Isotonix products provide both rapid delivery and good results.  
Isotonix products are isotonic because they match the fluids in the body, which have an almost constant concentration of dissolved particles like salts, sugars and minerals.  At this concentration, nutrients and molecules essential for cell metabolism are efficiently transported through cell membranes.  Isotonix products are formulated with the proper balance of fructose, glucose, citric acid, potassium bicarbonate and other key ingredients to assure that they are isotonic when properly prepared. 
Isotonix products deliver nutrients at the right rate and concentration for complete absorption of the nutrient-dense solution.  Isotonix is one of the most scientifically advanced nutrient delivery systems on the market.

Vitamin C
The best food sources of vitamin C include all citrus fruits (oranges, grapefruit, lemons and tangerines), strawberries, tomatoes, broccoli, brussel sprouts, peppers and cantaloupe. Vitamin C is a "fragile" vitamin and can be easily destroyed by cooking or exposure of food to oxygen.
Vitamin C promotes a vitamin "sparing" effect, allowing your body to better utilise multiple vitamins and minerals such as thiamin, riboflavin, pantothenic acid, biotin, folic acid, B12, vitamin E and the mineral calcium. It's also a cofactor or helper in the metabolism of folic acid, some amino acids and hormones. It is a co-factor in the synthesis of collagen and helps strengthen newly forming collagen. Vitamin C supports cardiovascular health and supports the immune system. Part of the protective action of vitamin C appears to be due to its antioxidant properties.   

Vitamin C helps supports cardiovascular health in a few different ways. It may assist in stabilizing cholesterol, blood lipids. It also helps to maintain endothelial cell function by promoting the synthesis of nitric oxide. By helping to maintain nitric oxide levels, vitamin C supports nitric oxide’s ability to preserve the integrity of the blood vessels. *

Vitamin C plays a crucial role in maintaining healthy connective tissues including collagen, elastin, fibronectin, proteoglycans, bone matrix and elastin-associated fibrillin.  

Vitamin C has become the world's most popular vitamin. The most convincing evidence suggesting the need for vitamin C supplementation is based on the fact that humans are incapable of producing vitamin C in their bodies. Vitamin C is best known for its antioxidant properties and it may be the most important water-soluble antioxidant in the body. Since it is water-soluble, vitamin C is flushed from the body each day. As humans don't always eat foods containing an adequate amount of vitamin C it often is beneficial to take a supplement.

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 has exhibited antioxidant activities. Vitamin A helps to maintain vision. It promotes normal bone growth and also contributes to a healthy immune system. Vitamin A supports normal epithelial differentiation, growth, reproduction, pattern formation during embryogenesis, bone development, hematopoiesis and brain development.  


What is the recommend daily allowance of Vitamin C? 
The RDA for the average adult male is 90 mg a day and for adult females it is 75 mg a day.

Does Isotonix Vitamin C Powder Drink provide the recommended daily allowance? 
Yes, Isotonix Vitamin C contains 500 mg of vitamin C per serving. In times of illness or distress, it may be helpful to supplement with a higher serving size of vitamin C.

Can Isotonix Vitamin C Powder Drink support my immune system?
Yes. Vitamin C has been heralded for quite possibly being the best immune system supporter and antioxidant available today. Vitamin C supports the immune system by protecting the body from free radical damage. As a water-soluble vitamin, ascorbic acid performs its antioxidant functions within the aqueous compartments of the blood and inside cells and can help restore the antioxidant potential of vitamin E (a fat-soluble antioxidant).*

Who needs to supplement with Isotonix Vitamin C Powder Drink?
Everyone over 18 should use Isotonix Vitamin C. Those who may especially need supplemental vitamin C include the elderly, those with weakened immune systems, smokers, those under heavy amounts of stress, those with cardiovascular conditions and athletes. 

Is it possible to take too much Isotonix Vitamin C Powder Drink?
Ascorbic acid is extremely safe even at relatively high levels (because most of the excess is excreted in the urine). At high doses (over 1000mg/day), some people can experience gastrointestinal side effects such as stomach cramps, nausea, and diarrhea.  

How does Isotonix Vitamin C Powder Drink aid in cardiovascular health? 
It  may assist in stabilizing cholesterol and blood lipids. It helps promote strong arterial walls. It helps the body maintain vitamin E, which has known benefits for the cardiovascular system. *

How should I take Isotonix Vitamin C Powder Drink?
Pour 1 level, white bottle capful of powder into the overcap. Add water to the line on the overcap (2. oz./60 mL) and stir. As a dietary supplement, take once daily or as directed by your healthcare provider. Maximum absorption occurs when taken on an empty stomach. This product is isotonic only if the specified amounts of powder and water are used.
