Dietary supplements

dietary supplements

Dietary supplements are products people take to add nutrients or other biologically active compounds to their regular diet, such as vitamins, minerals, herbs, amino acids, and antioxidants. They come in many forms, including tablets, capsules, powders, liquids, and gummies, and are usually intended to support overall health rather than to treat or cure a disease. Some supplements correct genuine dietary deficiencies, while others aim to support specific systems like joints, immunity, or nerve health. The evidence supporting different supplements varies widely: some are well studied and useful, while others have limited or mixed proof of benefit. The quality and strength of supplements can also vary between brands and batches. Because regulation is typically less strict than for prescription drugs, it is important to choose reputable manufacturers and look for products tested by independent labs. Supplements can be helpful when used appropriately, but they can also interact with medications or cause side effects, so consulting a healthcare provider before starting new products is recommended. In areas such as nerve protection or eye health, supplements may be one part of a broader plan that includes diet, lifestyle changes, and medical care. Knowing how supplements work, what evidence supports them, and their limits helps people make safer, more informed choices about using them to support health.
