Pre-workout is a generic term for a range of bodybuilding supplement products used by athletes and weightlifters to enhance athletic performance. Supplements are taken to increase endurance, energy, and focus during a workout. Pre-workout supplements contain a variety of ingredients such as caffeine and creatine, differing by capsule or powder products. The first pre-workout product entered the market in 1982, and since then the category has grown in use. Some pre-workout products contain ingredients linked to adverse effects. Although these products are not regulated, the Food and Drug Administration (FDA) warns consumers to be cautious when consuming them.
History In 1982, Dan Duchaine formulated the first pre-workout, called Ultimate Orange, in Venice, California. Ultimate Orange was commonly used among bodybuilders. Between the late 1990s and early 2000s, consumers alleged that an active ingredient in Ultimate Orange, called Ephedra, caused high blood pressure, strokes, seizures, cardiac arrhythmia, and heart attacks. The risk of using Ephedra gave rise to creatine. Creatine is a supplement that was used by a lot of athletes in the 1992 Olympics where it gained most of its popularity from. Creatine was considered a form of pre-workout in the late 1990s until the early 2000s where it was then later used with a mixture of other supplements. Creatine was negatively received when it was first introduced to the public until the last decade where it is now one of the most used supplements. In the early 2000s, supplement companies created more potent forms of pre-workout that caused the blood flow in muscles to increase temporarily, giving lifters a better "pump." These more potent supplements are called Arginine AKG, Arginine Malate, and Citrulline. In 2005, chemist Patrick Arnold formulated a pre-workout which contained a new ingredient called DMAA (dimethylamylamine). The product Jack3d gained notoriety for its potency, but its high concentrations of DMAA were suspected of causing shortness of breath, chest pain, and an elevated risk of heart attacks. Jack3d was banned in 2012 by the FDA.
Ingredients Pre-workout supplements are available in different forms, including tablets, capsules, liquids, powders, and bars. A number of common ingredients are used. There is considerable overlap between the ingredients used in pre-workout blends and other supplements intended for weight loss, improving mood, life extension, or as purported nootropics or aphrodisiacs, although certain ingredients tend to be found only in products intended to assist in bodybuilding or athletic training. Some ingredients such as caffeine, creatine and β-alanine are found in nearly all pre-workout blends, but each branded product is a "proprietary blend" with an average of 18 different ingredients, the exact composition and proportions of which can vary widely between different products.
