Vitamin C is the most unstable of all vitamins
Vitamin C is a water soluble vitamin. It is very unstable and cannot be stored in our body for a long period of time. Normally, we can obtain vitamin C from citrus fruits and leafy vegetables. However due to instability, it can easily be destroyed by heat, light and exposure to air. Although vitamin C can be absorbed through diet, it is also excreted in a short period of time.[1- 3] Therefore, most vitamin C supplements on the market are unable to provide optimal benefit to us.
Characteristics of Vitamin C time release formula
Vitamin C time release tablets slowly releases vitamin C throughout an eight hours period and help enhancing absorption of the vitamin. This supplement is specially formulated to maintain steady level of vitamin C in our blood. It also helps to provide vitamin C to our body constantly during the day and protect us against damage by sunlight and pollutants.[1- 5]
Why do we need to take Vitamin C time release tablets?
Vitamin C is essential for the formation and maintenance of collagen. It helps to bind connective tissue cells together. Vitamin C also promotes iron movement and absorption, enhances folic acid, fat and lipids metabolism, strengthens our bones and teeth, and keeps the capillaries and blood vessels healthy.[1-7] Vitamin C is an antioxidant which neutralizes free radicals and prevents their oxidative damage. This effect can help to prevent wrinkles and other health problems. [1-5]
Efficacy of Vitamin C with Vitamin P
Vitamin P (bioflavonoid) can be extracted from citrus fruits and added to this formulation. It synergistically enhances the effect of vitamin C and protects us against free radical damage caused by smoking and pollution. This formulation helps to boost our immune system and slow down the aging process.
Importance of Vitamin C
- Help to reduce fatigue induced by flu[1-4,6,9]
- Help to control skin, rhino and bronchial allergy caused by susceptible allergens[1-5]
- Protect and strengthen capillaries and connective tissues, prevent gum bleeding and skin bruise[1-4]
- Promote healthy bone growth in children, enhance their immune system and learning ability[1-4,9]
- Involve in collagen synthesis which promote wound healing especially aftercosmetic surgery and burn[1-5,9]
- Act as an antioxidant and help to prevent damage from sunlight (UV radiation) and free radical oxidation which may lead to acceleration of the aging process
- Maintain good appetite and healthy gastrointestinal and digestion system 
- Promote the metabolism of tyrosine and tryptophan in amino acids 
Recommended daily dose:
For adults and children age of 12 years and up take 1 tablet daily or as recommended by physicians.
