Are Health Supplements For You?

The past two decades has seen a dramatic increase in the number of people wanting to take responsibility for their own health, and greater interest in the role played by diet in maintaining good health. It has also seen an increase in the number of health supplements available in the UK as well as a growing awareness of the benefits of health supplements for many people.

However the increase in products now widely available, as well as the publication of information on health supplements that is often conflicting, has inevitably resulted in some confusion amongst consumers.

The Health Supplements Information Service was set up in 1999 to provide up-to-date information about vitamins, minerals and food supplements and this information has been produced to answer some of the most common questions asked about these products.

It is clear that many of us can benefit from supplements at certain times in our lives and I hope that after reading this booklet you will be able to make more confident decisions about your own nutritional requirements.

Question

Does everybody get enough nutrients from their diet?
Many people do get enough nutrients from their diet - as defined by the Recommended Daily Allowance [RDA] - but there will always be some people who are either deficient in one or more nutrients or who have special nutritional or medical needs for particular nutrients at certain times in their lives. Such people include young children and adolescents, pregnant and breastfeeding women, immobile, housebound or institutionalised elderly people, vegans and some vegetarians, smokers, heavy* drinkers, people who are chronically ill, including those with immune deficiency disorders, and anybody on a restrictive diet, including long term slimmers.

Nutrients can be lost from food as a result of poor methods of storage, preparation and cooking. In addition, busy lifestyles mean that people are more inclined to skip meals and grab individual snacks without giving thought to putting together properly balanced meals which would provide the right mix of nutrients. To obtain optimal nutrient intake, people have to decide whether to change their diet or lifestyle or whether to take food supplements. In all cases, they should obtain up to date information on the recommended amounts required for a specific health benefit.

Finally, there are also some nutrients which may be difficult to obtain in adequate quantities from food, and therefore can be taken as a supplement. For example, cod liver oil as a source of vitamin D and essential fatty acids, or folic acid for development of a healthy neural tube during pre-conception and through the first 12 weeks of pregnancy.
