Supplements are products that provide nutrients like vitamins, minerals, amino acids, or herbal extracts to add to what you get from food. They come in forms such as pills, capsules, powders, liquids, and gummies, and are meant to support health in specific ways. People use them to correct nutrient deficiencies, support particular life stages, or try to improve overall well-being. Unlike prescription medicines, supplements are usually available over the counter, but that doesn’t mean they are without risks. Because they are not regulated as strictly as drugs, the quality and strength can vary widely between brands. It matters to know that supplements can interact with medications or cause side effects, so checking with a healthcare provider is important before starting anything new. They are most helpful when they fill a real gap — for example, a diagnosed deficiency or increased need during pregnancy or aging — rather than as a substitute for a healthy diet. Look for products that have third-party testing or clear labels listing ingredients and amounts to reduce the chance of contamination or misleading claims. Pay attention to dosage instructions and avoid taking multiple products that provide the same nutrient, which can lead to excessive intake. When used carefully and informedly, supplements can be a useful part of a health plan, but they work best alongside good eating habits and regular medical advice.
