Vitamin D3 (Cholecalciferol)
Vitamin D is a fat-soluble vitamin that plays an essential role in the body. It is required to regulate the levels of calcium and phosphorous in the blood.
Vitamin D is commonly used to promote healthy bones and strengthen teeth.
Our bodies produce Vitamin D in response to exposure to sunlight
Spending a short period of time in the sun each day supplies the Vitamin D your body needs, but people who do not get outdoors, or who are darker skinned, may not be generating enough Vitamin D.
Generally around 30 minutes of early morning or late afternoon sun on the face, hands and arms, two to three time a week will generate sufficient Vitamin D.
Vitamin D is present in only a few foods.
Vitamin D only occurs naturally in foods such as fatty fish, whole egg, and liver.
Mild Vitamin D deficiency is not uncommon and can harm the bones, and also cause diarrhoea, insomnia, nervousness and muscle twitches.
