Evidence reviews

Dietary supplements for established atopic eczema in adults and children

Eczema is a skin condition characterised by an itchy, red rash, which affects 5% to 20% of people worldwide. There is no cure, but many treatments can help improve the skin's condition, making life easier. In those for whom these treatments do not work well or who fear their long‐term effects, there is often a belief that either something in their diet, or something missing in their diet, is making their eczema worse.

Zinc supplements for preventing middle ear infections

Middle ear infections are common, especially among young children, usually causing earache and some temporary (occasionally permanent) hearing loss. Zinc is an essential micronutrient, which has a role in the optimal functioning of the immune system and resistance to infection. It must be consumed regularly as it cannot be stored in the body. Some people, especially children in low‐ and middle‐income countries, may not have adequate zinc intake from food alone. Researchers have examined the potential role of zinc supplements in preventing infective illnesses. Therefore we wanted to discover whether zinc supplements have any role in preventing middle ear infections.

Dietary supplements for treating age-related macular degeneration (AMD)

There is no evidence that dietary supplements can prevent age-related macular degeneration (AMD). But some combinations of vitamins and minerals may help delay the development of late-stage AMD.Dietary supplements contain nutrients that also occur naturally in our food, such as vitamins and minerals, but in a concentrated form and often at a higher dose. They may contain herbal substances like St. John's wort (hypericum) or garlic, or animal products such as fish oil. Dietary supplements are available in many different forms, including tablets, capsules, powder or liquids. They do not require a prescription and are also available outside of pharmacies.

What are dietary supplements?

“Vitamins strengthen our immune system,” and “Omega 3 is good for your heart”: Dietary supplements are often marketed using a number of different promises, and they are available everywhere, from pharmacies and supermarkets to the internet. But do we really need all of these tablets, powders and capsules? What makes dietary supplements different from medicine and can they also be harmful?
