Dietary protein supplementation

"Dietary protein supplementation" is **not** a molecular target such as a receptor, enzyme, transporter, or gene. Instead, it refers broadly to the practice of increasing dietary protein intake through supplements—such as powders or bars—derived from animal or plant sources. These supplements are used primarily for nutritional purposes: supporting muscle growth and repair during resistance exercise training, aiding recovery after injury or illness, and helping meet increased protein needs in older adults or those with restricted diets[1][5][6]. Common forms include whey (from milk), casein (also from milk), soy, pea, hemp seed proteins among others[2][5]. Protein supplements are not drugs nor do they act via specific molecular mechanisms typical for therapeutic targets. Their effects are systemic and nutritional rather than pharmacological—they provide essential amino acids required by the body but do not interact directly with cellular receptors or enzymes like traditional drug targets. While beneficial for certain populations—such as athletes undergoing resistance training where they can enhance gains in lean mass and strength—the use of dietary protein supplements is generally unnecessary for healthy adults who can meet their needs through food alone. Safety concerns include potential contamination due to limited regulatory oversight and possible adverse effects in people with severe kidney impairment[1][3]. In summary: "Dietary protein supplementation" is **not** an appropriate entry for a therapeutic target database focused on molecules such as receptors/enzymes/transporters; it describes an intervention strategy rather than a discrete biological molecule.[1][2][3]
