More recently, the prevalence of designer steroids with unknown safety and pharmacological effects has increased. In 2013, one-third of the supplements tested were adulterated with unlisted steroids. As a result, the incidence of products adulterated with illegal ingredients has continued to rise. In the United States, the manufacturers of dietary supplements do not need to provide the Food and Drug Administration with evidence of product safety prior to marketing. In 2015, Consumer Reports reported unsafe levels of arsenic, cadmium, lead and mercury in several of the protein powders that were tested. In addition, ingredients listed have been found at times to be different from the contents. While many of the claims are based on scientifically-based physiological or biochemical processes, their use in bodybuilding parlance is often heavily colored by bodybuilding lore and industry marketing and, as such, may deviate considerably from traditional scientific usages of the terms. Quality standards, event notability guideline, or encyclopedic content policy.

The greatest reduction in skeletal muscle damage from a single bout of exercise appears to occur when calcium HMB is ingested 1–2 hours prior to exercise. The inhibition of exercise-induced skeletal muscle damage by HMB is affected by the time that it is used relative to exercise. HMB is believed to produce these effects by increasing muscle protein synthesis and decreasing muscle protein breakdown by various mechanisms, including activation of the mechanistic target of rapamycin (mTOR) and inhibition of the proteasome in skeletal muscles. When combined with an appropriate exercise program, dietary supplementation with β-hydroxy β-methylbutyrate (HMB) has been shown to dose-dependently augment gains in muscle hypertrophy (i.e., the size of a muscle), muscle strength, and lean body mass, reduce exercise-induced skeletal muscle damage, and expedite recovery from high-intensity exercise. Main article: Beta-Hydroxy beta-methylbutyric acid It is widely believed that the 1994 DSHEA further consolidated the position of the supplement industry and lead to additional product sales. Since that time, manufacturers did not have to provide FDA with the evidence to substantiate safety or effectiveness unless a new dietary ingredient was added. Food and Drug Administration (FDA) before distributing the products. Under DSHEA, responsibility for determining the safety of the dietary supplements changed from the government to the manufacturer, and supplements no longer required approval from the U.S. In October 1994, the Dietary Supplement Health and Education Act (DSHEA) was signed into law in the USA. The 1970s and 1980s marked a dramatic increase in the growth of the bodybuilding supplement industry, fueled by the widespread use of modern marketing techniques and a marked increase in recreational bodybuilding. Johnson began to popularize and market egg-based protein powders marketed specifically at bodybuilders and physical athletes. In the 1950s, with recreational and competitive bodybuilding becoming increasingly popular, Irvin P. Later, bodybuilder Earle Liederman advocated the use of "beef juice" or "beef extract" (basically, consomme) as a way to enhance muscle recovery. In the 1910s, Eugen Sandow, widely considered to be the first modern bodybuilder in the West, advocated the use of dietary control to enhance muscle growth. A number of herbal concoctions and tonics have been used by strong men and athletes since ancient times across cultures to try to increase their strength and stamina. Supplements are sold either as single ingredient preparations or in the form of "stacks" – proprietary blends of various supplements marketed as offering synergistic advantages.Īthletes in ancient Greece were advised to consume large quantities of meat and wine. Among the most widely used are high protein drinks, pre-workout blends, branched-chain amino acids (BCAA), glutamine, arginine, essential fatty acids, creatine, HMB, whey protein, ZMA, and weight loss products. Bodybuilding supplements may contain ingredients that are advertised to increase a person's muscle, body weight, athletic performance, and decrease a person's percent body fat for desired muscle definition. Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding, weightlifting, mixed martial arts, and athletics for the purpose of facilitating an increase in lean body mass.
