Dietary supplements, including vitamins, minerals, herbal extracts, and amino acids, can provide essential nutrients that may be lacking in a regular diet. Nutritionist Diksha Dayal advises that while these supplements can support health, they should not replace a balanced diet. It is essential to consult a healthcare professional before starting any new supplement regimen, as improper use can lead to adverse effects. Supplements like multivitamins, omega-3 fatty acids, and probiotics are common, but their safety depends on factors such as dosage, quality, and potential interactions with other medications. Dayal emphasizes the importance of choosing trusted brands that adhere to quality standards and have their products independently tested. Users should be cautious of supplements that make exaggerated claims and should always monitor their body's reactions after starting a new product. Overall, while dietary supplements can be beneficial, they must be used wisely to avoid risks associated with nutrient overdoses and harmful ingredients.
