Consuming dietary supplements became a part of our lifestyle as many nutrients are lacking in our new dietary practices in this fast-paced world. But, there is a not-so-familiar dimension for this. For example, if you think, you are taking enough supplements to better your health, sometimes you might be wrong. Consider, you are taking a Vitamin-A supplement in B-carotene form and if your body has reduced capacity to convert B-carotene to Vitamin-A, you still possess the risk of deficiency of vitamin-A. Thanks to the advancement in medical science, now it is easier to find which nutrients you need in supplement form by doing a metabolic assessment using various advanced techniques. Also, it is crucial to find out the right brand. The purity, efficacy and bioavailability of the supplements play a vital role, as this market is flooded with products and some of them are sham, too. Consuming a lot of supplements won’t make you healthy but the right choice of them as per your need and its efficacy are the keys.<br />Keywords: dietary supplements, lifestyle,diet
