Supplements should never be looked at as an alternative to eating a good diet, but can help to fill the gaps in your diet. For example, in the UK there are certain things such as Selenium, Magnesium and Zinc that are hard to obtain from our diets.
Vitamin D is usually made by the action of sunlight on our skin, but during cloudy periods and the winter months it’s hard to make enough. People with restrictive diets can miss out on certain nutrients. In all these cases supplements can be very useful. Supplements can also be used to maintain health and assist various health conditions.
