Why Choose Isotonix Vitamin C?
Isotonix Vitamin C is an isotonic-capable food supplement made with a combination of vitamin C, beta-carotene and potassium in a delicious natural orange flavour. 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. Isotonix Vitamin C contains 500 mg of vitamin C to contribute to the normal function of the immune system and to protect cells from oxidative stress.
Isotonic, which means “same pressure,” bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state.
Isotonix food supplements are delivered in an isotonic solution. This means that the body has less work to do to in obtaining maximum absorption. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.

Ingredients
Vitamin C (Ascorbic Acid)
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 contributes to the protection of cell constituents from oxidative stress, in addition to increasing iron absorption. Vitamin C contributes to normal collagen formation and the normal function of bones, teeth, cartilage, gums, skin and blood vessels. Vitamin C contributes to the normal function of both the immune and nervous systems. Vitamin C contributes to normal energy-yielding metabolism and it may contribute to the reduction of tiredness and fatigue. Vitamin C contributes to the regeneration of the reduced form of Vitamin E, and it also contributes to normal psychological functions.
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. The best sources of vitamin A include organ meats (such as liver and kidney) egg yolks, butter, carrot juice, squash, sweet potatoes, spinach, peaches, fortified dairy products (such as milk and some margarines) and cod liver oil. Vitamin A contributes to the maintenance of vision, skin, and mucous membranes. It contributes to the normal function of the immune system, normal cell differentiation and it has a role in the process of cell specialisation.
Potassium (Bicarbonate)
Potassium is an electrolyte and essential macromineral that helps maintain fluid balance in the body. Foods rich in potassium include bananas, oranges, cantaloupe, avocado, raw spinach, cabbage and celery. It contributes to normal functioning of the nervous system, normal muscle function, and to the maintenance of normal blood pressure.
FAQs
What is the RDI of Vitamin C? Does Isotonix Vitamin C provide the RDI?
The RDI for the average adult male and female is 45 mg a day. Yes, Isotonix Vitamin C contains 500 mg of vitamin C per serving, which is an optimal amount for immune system maintenance. In times of illness or distress it may be helpful to supplement with a higher serving size of vitamin C.
Who needs to supplement with Isotonix Vitamin C Formula?
Basically, everyone over 18 should use Isotonix Vitamin C because our bodies do not make Vitamin C and very few of us get the recommended servings of fruits and vegetables in our daily diets. 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 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 1000mg/day), some people can experience gastrointestinal side effects such as stomach cramps, nausea, and diarrhoea. It is recommended that you take Vitamin C supplements in gradual servings throughout the day to achieve maximum benefits.
How do I take Isotonix Vitamin C?
Pour one level, white bottle capful of powder into the overcap. Add water to the line on the overcap (2 fl. oz./60 mL) and stir. As a food supplement, take once daily. Maximum absorption occurs when taken on an empty stomach. This product is isotonic only if the specified amounts of powder and water are used.
Are there any warnings or contraindications for Isotonix Vitamin C?
If you are currently using prescription drugs, have an ongoing medical condition, or if you are pregnant or breastfeeding, consult your healthcare provider before using this product.
Are there any allergens with Isotonix Vitamin C?
This is a vegetarian product and contains no added wheat, soy, yeast, gluten, artificial flavour, starch, salt, preservatives or milk.
