Do dietary supplements prevent AMD?
There is no that dietary supplements can prevent age-related macular degeneration (AMD). But certain 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 various forms, including tablets, capsules, powder or liquids. You can buy them without a prescription and in different kinds of shops – not just in pharmacies.
