Bodybuilding supplement - Wikipedia. Bodybuilding supplements are dietary supplements specifically marketed to those involved in bodybuilding, weightlifting and athletics. Among the most widely used are vitamins, protein, 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 . While many bodybuilding supplements are also consumed by the general public, their salience and frequency of use may differ when used specifically by bodybuilders. ![]() They may be marketed as a product to replace meals, enhance weight gain, promote weight loss or improve athletic performance. Annual sales of sport nutrition products in the US is over $2. US) according to Consumer Reports. 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. Later, bodybuilder Earle Liederman advocated the use of . In 1. 95. 0s with recreational and competitive bodybuilding becoming increasingly popular Irvin P. Johnson began to popularize and market egg- based protein powders marketed specifically at bodybuilders and physical athletes. The 1. 97. 0s and 1. In October 1. 99. Dietary Supplement Health and Education Act (DSHEA) was signed into law in the USA. Under DSHEA, responsibility for determining the safety of the dietary supplements changed from government to the manufacturer and supplements no longer required approval from the U. S. Food and Drug Administration (FDA) before distributing product. 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. It is widely believed that the 1. DSHEA further consolidated the position of the supplement industry and lead to additional product sales. In addition, ingredients listed have been found at times to be different from the contents.

In 2. 01. 5, Consumer Reports reported unsafe levels of arsenic, cadmium, lead and mercury in several of the protein powders that were tested. This resulted in liver transplants and, in some cases, death to the patient. Some have argued that the liver damage is more often caused by prescription drugs rather than supplements. In addition, some argue that bodybuilders, by virtue of their unique training and goals, require higher- than- average quantities of protein to support maximal muscle growth. Protein powders are the most popular and may have flavoring added for palatability. The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. ![]() Possible side effects Click on a question below to reveal an answer. I notice a tendency towards bad breath. Why is this? The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility: Whey protein contains high levels of all the essential amino acids and branched- chain amino acids. It also has the highest content of the amino acid cysteine, which aids in the biosynthesis of glutathione. For bodybuilders whey protein provides amino acids used to aid in muscle recovery. There are three types of whey protein: whey concentrate, whey isolate, and whey hydrolysate. Whey concentrate is 2. Whey hydrolysate is enzymatically predigested and therefore has the highest rate of digestion of all protein types. Whey protein is usually taken immediately before and after a workout . Casein is usually taken before going to bed. Since rice protein is low in the amino acid lysine, it is often combined with pea protein powder to achieve a superior amino acid profile. ![]() Pea protein is a hypoallergenic protein with a lighter texture than most other protein powders. Pea protein has an amino acid profile similar to that of soy, but pea protein does not elicit concerns about unknown effects of phytoestrogens. Pea protein is also less allergenic than soy. Pea protein has high fiber content and has no allergic ingredients and therefore is easy for digestion as compared to whey protein. Pea protein is a slow digesting protein and is able to keep you full longer. Often has mesh or a metal whisk inside to breakdown lumps in the mixture. Some nutritionists claim that osteoporosis may occur from excessive protein intake because protein can put pressure on the kidneys and lead to bone loss due to calcium leaching. Amino acids have been used by some companies to artificially inflate and falsify protein values in their product (protein spiking). Many protein supplements explicitly indicate on the label that no protein spiking has occurred. Amino acids. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen. To deal with this, many supplements also have aromatase inhibitors and DHT blockers such as chrysin and 4- androstene- 3,6,1. To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown. Although initially available over the counter, their purchase was made illegal without a prescription in the US in 2. They remain legal, however, in the United Kingdom and the wider European Union. Their use is prohibited by most sporting bodies. Creatine. A number of scientific studies have shown that creatine can improve strength. In addition, recent studies have also shown that creatine improves brain function. Though all types of creatine are sold for the same purposes, there are subtle differences between them, such as price and necessary dosage. In The New Encyclopedia of Modern Bodybuilding, 2nd ed., author Arnold Schwarzenegger states: Creatine monohydrate is regarded as a necessity by most bodybuilders. Creatine monohydrate is the most cost- effective dietary supplement in terms of muscle size and strength gains. This can be accomplished by mixing powdered creatine with grape juice, lemonade, or many high glycemic index drinks. MRPs are generally high in protein, low in fat, have a low to moderate amount of carbohydrates, and contain a wide array of vitamins and minerals. The majority of MRPs use whey protein, casein (often listed as calcium caseinate or micellar casein), soy protein, and/or egg albumin as protein sources. Carbohydrates are typically derived from maltodextrin, oat fiber, brown rice, and/or wheat flour. Some MRPs also contain flax oil powder as a source of essential fatty acids. MRPs can also contain other ingredients, such as creatine monohydrate, glutamine peptides, L- glutamine, calcium alpha- ketoglutarate, additional amino acids, lactoferrin, conjugated linoleic acid, and medium- chain triglycerides. A sub- class of MRPs are called 'weight gainers' and have a high ratio of carbohydrates: protein. Where a MRP would have a 0. Carbohydrates: Protein a weight gainer would have in the order of between 3- 5: 1 ratios. Until 2. 00. 4 almost every product found in this supplement category comprised the .

In conclusion, HMB treatment clearly appears to be a safe potent strategy against sarcopenia, and more generally against muscle wasting, because HMB improves muscle mass, muscle strength, and physical performance. It seems that HMB is able to act on three of the four major mechanisms involved in muscle deconditioning (protein turnover, apoptosis, and the regenerative process), whereas it is hypothesized to strongly affect the fourth (mitochondrial dynamics and functions). Moreover, HMB is cheap (~3. US dollars per month at 3 g per day) and may prevent osteopenia (Bruckbauer and Zemel, 2. Tatara, 2. 00. 9; Tatara et al., 2.
