Vitamin is an organic compound required by an organism as a vital nutrient in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when it cannot be synthesized in sufficient quantities by an organism and must be obtained from the diet.
Thus, the term is conditional both on the circumstances and on the particular organism. For example, ascorbic acid (vitamin C) is a vitamin for humans, but not for most other animals.
Supplementation is important for the treatment of certain health problems but there is little evidence of benefit when used by those who are otherwise healthy!
Dietary elements, commonly called “dietary minerals” or “minerals”, are the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen present in common organic molecules.
The term “dietary mineral” is archaic, as the substances it refers to are chemical elements rather than actual minerals.
Herbal medicine is the use of plants for medicinal purposes. Plants have been the basis for medical treatments through much of human history, and such traditional medicine is still widely practiced today.
Modern medicine recognizes herbalism as a form of alternative medicine, as the practice of herbalism is not strictly based on evidence gathered using the scientific method.
Modern medicine, does, however, make use of many plant-derived compounds as the basis for evidence-tested pharmaceutical drugs, and phytotherapy works to apply modern standards of effectiveness testing to herbs and medicines that are derived from natural sources.
The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells, and certain animal parts.
Amino acids are biologically important organic compounds composed of amine (-NH2) and carboxylic acid (-COOH) functional groups, along with a side-chain specific to each amino acid.
The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino acids.
Amino acids can be divided into three categories: essential amino acids, non-essential amino acids, and conditional amino acids.
Essential amino acids cannot be made by the body and must be supplied by food. Non-essential amino acids are made by the body from essential amino acids or in the normal breakdown of proteins.
Conditional amino acids are usually not essential, except in times of illness, stress, or for someone challenged with a lifelong medical condition
Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them.
The term “essential fatty acid” refers to fatty acids required for biological processes but does not include the fats that only act as fuel.
Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding and athletics. Bodybuilding supplements may be used to replace meals, enhance weight gain, promote weight loss, or improve athletic performance.
Among the most widely used are vitamin supplements, protein drinks, branched-chain amino acids (BCAA), glutamine, essential fatty acids, meal replacement products, creatine, weight loss products, and testosterone boosters.
Supplements are sold either as single ingredient preparations or in the form of “stacks” – proprietary blends of various supplements marketed as offering synergistic advantages.
While many bodybuilding supplements are also consumed by the general public their salience and frequency of use may differ when used specifically by bodybuilders.
