"Vitamins are substances that your body needs to grow and develop normally. There are 13 vitamins your body needs. They are vitamins A, C, D, E, K and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate). You can usually get all your vitamins from the foods you eat. Your body can also make vitamins D and K. People who eat a vegetarian diet may need to take a vitamin B12 supplement.
Each vitamin has specific jobs. If you have low levels of certain vitamins, you may develop a deficiency disease. For example, if you don't get enough vitamin D, you could develop rickets. Some vitamins may help prevent medical problems. Vitamin A prevents night blindness.
The best way to get enough vitamins is to eat a balanced diet with a variety of foods. In some cases, you may need to take a daily multivitamin for optimal health. However, high doses of some vitamins can make you sick."
The relationship between vitamin C and calcium is an important — if not tricky — one. Vitamin C can support calcium absorption, but excess amounts of vitamin C can have a detrimental effect on calcium stores. Finding the right balance between vitamin C and calcium can be a step in the right direction for people who want to increase calcium absorption, protect themselves against tissue calcification, prevent diseases and get the most out of their supplements.
