Nutrition Guide

MET-Rx is a brand name of nutritional supplements. The brand is best known as the product to pioneer a new category of bodybuilding supplements known as Meal Replacement Powders or MRPs.

Bodybuilding supplements are substances taken by athletes involved in weight training or other sports to aid in the building of lean muscle mass or to cause fat loss. Bodybuilding supplements may also be used to improve sports performance and improve recovery from events and training. One important distinction exists in many weight training groups between supplements and anabolic steroids. There is a common misconception among non-supplement-users that supplementation for muscle-building purposes is the same as steroid use or, at the very least, leads to steroid use.[citation needed] However, this charge is often challenged by supplement users on the grounds that supplements

From Wikipedia, the free encyclopedia Not to be confused with insure. Not to be confused with inshore. Ensure can mean: To make sure or certain of something: see wiktionary:ensure A food and beverage brand owned by Abbott Laboratories. The most well known of these products is the Ensure Shake, intended to be served as a snack or meal replacement.

A thermogenic is a broad term for any supplement that the manufacturer claims will cause thermogenesis, resulting in an increased metabolic rate, increased body temperature and consequently an increased rate in the burning of body fat. Until recently almost every product found in this supplement category comprised the "ECA stack": ephedrine, caffeine and aspirin. However, on February 6, 2004 the Food and Drug Administration (FDA) banned the sale of ephedra and its alkaloid, ephedrine, for use in weight loss formulas. Several manufacturers replaced the ephedra component of the "ECA" stack with bitter orange or citrus aurantium (containing synephrine) instead of

There are several naturally occurring plants and vitamins as well as synthetic chemicals that supplement companies claim may produce an increase in testosterone levels. However, the validity of many of these products is questionable due to a lack of valid scientific research showing their effectiveness at this time. Some commonly taken supplements of this type are ZMA and Tribulus terrestris. The relatively new drug 4-androstene-3,6,17-trione may increase the testosterone-estrogen ratio.[citation needed] Excess testosterone can cause undesirable side effects, such as hair loss and acne,[citation needed] and may be converted into estrogens,[11] which can have undesirable effects on males.[12]

Metabolife was founded in the early 1990's by Michael Ellis, a former police officer on probation for charges relating to his involvement with a methamphetamine lab.[3][4] Ellis and a boyhood friend, Michael Blevins, were arrested in 1989 for producing and distributing methamphetamine. Both Ellis and Blevins cooperated with federal authorities in return for lighter sentences. Following Blevins' release from prison, the two formed Metabolife to market ephedra, an herbal supplement containing compounds chemically related to methamphetamine.[4] Metabolife's ephedra supplement was initially marketed as a bodybuilding supplement, but in 1995 was rebranded as an aid for dieting. The product became highly successful

A gainer is a bodybuilding supplement usually comprised of both high and low glycemic carbohydrates and protein (usually in the form of calcium caseinate, milk and whey protein) and often other nutrients such as certain vitamins and minerals. Gainers are used by bodybuilding and strength athletes, both amateur and professional alike. When performing intensive exercise the stress can cause the release of hormones such as cortisol in order to quickly make available energy to the body. Cortisol forces breakdown of glycogen, protein (muscle) and fat deposits which are used in gluconeogenesis. Gainers seek to combat this effect after (and sometimes during)

ZMA (Zinc monomethionine aspartate and Magnesium Aspartate) is a supplement used by bodybuilders and athletes. It was developed by Victor Conte (founder of BALCO Laboratories in Burlingame, California) and is a combination of zinc, magnesium and vitamin B6. The formula is "patent pending" and the name "ZMA" trademarked by SNAC System Inc, also founded by Victor Conte. ZMA is claimed to raise testosterone and IGF-1 levels which may aid in gaining muscle size and strength. ZMA is a combination of two minerals, zinc and magnesium, and Vitamin B-6 or pyridoxine. All three of these compounds are important in biological processes, and

Glutamine is the most abundant amino acid found in human muscle and is supplemented because supplement manufacturers claim the body's natural glutamine levels are depleted during anaerobic exercise. It is argued that bodybuilders should supplement with glutamine, as deficiency may lead to a weakened immune system and wasting of muscle tissue.[citation needed] It is sold as a micronized, instantly soluble powder. Some studies [2] [3] have shown there to be no significant effect of glutamine on bench press strength, knee-extension torque or lean muscle mass when compared to controls taking a placebo, though another study found that glutamine is beneficial

Bodybuilders often take a powdered form of protein, the essential building blocks for muscle. Protein powder is generally consumed immediately before and after exercising, or in place of a meal. Having sufficient protein intake allows for efficient growth and repair of muscle tissue. Whey protein is the most commonly used type of protein. It contains high levels of all the essential amino acids not produced by the human body, and is absorbed by the body very quickly. Casein protein (or Milk protein) is the richest in glutamine, an amino acid that aids in recovery, and has casomorphin which helps the body to

The activity of boldenone is mainly anabolic, with a low androgenic potency. It has a very long half-life, and can show up on a steroid test for up to 1.5 years, due to the long undecylenate ester attached to the parent steroid. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys. The drug is commonly used in doping within bodybuilding, even though this use is illegal. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like

The original MET-Rx meal replacement product came in two canisters - one labeled MET-Rx "base" and the other MET-Rx "plus." The instructions were to take two scoops of the base and one scoop of the plus and mix them in milk or water. As the product grew more popular, it was released combining the "base" and "plus" into one formula while removing the micellar casein component.
