Why Choose Isotonix Vitamin C?

Why Choose Isotonix Vitamin C?

Fuel your immunity with the world’s most popular vitamin – vitamin C! Vitamin C is an antioxidant that reduces free radicals formed in the body and plays a significant role in a variety of metabolic functions. It strengthens the immune system, prevents vitamin C nutritional deficiencies, and helps decrease common cold duration. It also helps with skin and eye health. Only Isotonix offers Vitamin C using isotonic delivery, providing maximum nutrient absorption. 

Isotonix Vitamin C is an isotonic-capable dietary supplement made with a combination of vitamin c, beta-carotene and potassium in a delicious natural orange flavour. 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 help with your immune system to give your body that added boost during cold season. One serving supplies 500 mg of vitamin C, the equivalent of 7 oranges, 16 lemons, or 6 grapefruits. It is great for helping with allergies and the common cold, is to be used for the prevention of vitamin C deficiencies, and to improve the general wellbeing among others. 

The two most important factors when searching for quality nutritional supplements are potency and absorption. Our Isotonix Vitamin C sets itself apart from other products on the market by providing you with the maximum nutrient absorption in the shortest amount of time via our patented Isotonix delivery system. The liquid composition of Isotonix Vitamin C places vitamins and minerals like Vitamin C in an optimal position for absorption, ensuring a superior delivery to the body’s systems to support a healthy immune system and provide antioxidant protection to the body.

Isotonix Delivery System

Isotonix Delivery System

Isotonix - the World's Most Advanced Nutraceuticals
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 dietary supplements are delivered in an isotonic solution. This means that the body has less work to do 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, brussels sprouts, capsicums 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. 


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 1 level, white bottle capful (3.3g) of powder into the clear overcap. Add water to the line on the overcap (60 mL) and stir for one dose. Drink immediately after mixing is complete. 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. 

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.

最好喝最有效的维他命C

之前用过很多牌子的维他命C，因为知道它是提高免疫力最好的产品。但是从味道到效果来讲都不是我很喜欢的。知道遇到等渗压系列的维他命C，味道超级好喝，而且去年一个冬天都没有发烧，感冒过两次但两天就好了，以前都要两个礼拜才可以好。而且我意外的发现我生完孩子脸上的色斑也淡了很多。非常开心，会一直用下去。
