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.
Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
