Vitamin D deficiency becomes very common throughout winter due to lack of sunlight, which we need to make vitamin D. Although diet can provide small amounts of vitamin D this is not enough to ensure adequate vitamin D levels and that is why vitamin D supplements are very important.

Vitamin D from cod liver oil was unknowingly used to treat infections long before the arrival of antibiotics and it is now known that your immune system’s ability to fight infection is dependent on adequate vitamin D.  Studies have shown vitamin D has a protective effect against respiratory tract infections.

Current recommendations for vitamin D intake from supplements are a minimum of 400 IU daily for children and at least 600 IU daily for adults.

If you are pregnant, older age, have darker skin, are overweight or work indoors your risk of vitamin D deficiency is particularly high. Vitamin D is extremely safe and no cases of harm have ever been reported at commonly recommended doses.

Vitamin C is known to be a potent immune stimulating nutrient. It has been shown to inhibit viral replication and can reduce the severity of the common cold.

The human body cannot produce or store vitamin C. Therefore, it’s essential to consume it regularly in sufficient amounts.

Vitamin C supplementation may prevent the common cold and shorten the duration of symptoms. Clinical assessment has demonstrated that 2000mg of vitamin C per day for two weeks reduced blood histamine concentrations by 30-40% in adult subjects.

Vitamin C can be consumed through diet or a good quality liposphereic vitamin supplement.
