Vitamin C
Vitamin C is the highest selling supplement in New Zealand.

Vitamin C is a water-soluble vitamin that must be obtained from diet or supplements.
It has been linked to many impressive health benefits, such as boosting antioxidant levels, reducing blood pressure, reducing heart disease risk, protecting against gout attacks, improving iron absorption, boosting immunity and reducing dementia risk.
It is found in many fruits and vegetables, including oranges, strawberries, kiwi fruit, bell peppers, tomatoes, broccoli, cabbage, kale and spinach. Overall, vitamin C supplements are a great and simple way to boost your vitamin C intake if you struggle to get enough from your diet.
Antioxidant and anti-inflammatory
Vitamin C is a strong antioxidant that can strengthen your body’s natural defences against the inflammatory effects of free radicals molecules. These are produced when your body breaks down food or is exposed to tobacco smoke and radiation. Free radicals might play a role in heart disease, cancer and other diseases.
Vitamin C has been found to be an important co-factor in 70-80 key enzyme processes in the body, which cover a whole raft of biological activities, from the growth of blood vessels through to the regulation of our genetic code. Vitamin C is at the hub of almost every biological function that we know.
Immune boost
One of the main reasons people take vitamin C supplements is to boost their immunity.
Vitamin C is involved in many parts of the immune system. It helps encourage the production of white blood cells, which help protect the body against infections.
By helping white blood cells function more effectively vitamin C can strengthen your skin’s defence system and help wounds to heal faster.
Dosage
Because vitamin C is water soluble it is quickly excreted from the body. Therefore to maintain high levels of vitamin C in the body you should take repeated doses several times a day.
While the minimum daily dose required to prevent a deficiency disease like scurvy is small (just 50mg per day) many people take a daily dose of 1000mg and use this dose two or three times per day to boost their body’s immune system.
