Vitamins and Minerals
Vitamins and minerals are normally obtained through a healthy diet, and are absolutely crucial to intake for optimal human functioning.
Ingesting optimal levels results in optimal human functioning and having lesser than optimal intake results in non-optimal states.
Each vitamin or mineral has a recommended intake range which should be aimed for through diet first and supplementation afterwards.
People as vegans, young children, older people, pre-pregnant and pregnant women, alcohol consumers, lactating women, smokers, people with absorbsion problems etc. are highly adviced to use vitamin and mineral suplements.
Minerals also help your body function. Some minerals, like iodine and fluoride, are only needed in very small quantities. Others, such as calcium, magnesium, and potassium, are needed in larger amounts.
