|Dietary supplements are those food materials which provide the nutrients that are not consumed in sufficient amount from food or else which completes the diet. These include vitamins, minerals, fiber, fatty acids, or amino acids, among other substances. There are nearly about 50,000 dietary supplements available at present. These products are not designed to prevent or treat any disease but only to fulfill the need of a complete diet.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
