A '''gainer''' is a [[bodybuilding supplement]] usually composed of both high and low [[glycemic]] [[carbohydrates]] and [[protein]] (usually in the form of calcium caseinate, milk and [[whey protein]]) and often other [[nutrient]]s such as certain [[vitamin]]s and [[mineral]]s.

==History==
Gainers are used by [[bodybuilding]] and strength athletes, both amateur and professional alike, as a weight gain supplement.

When performing intensive exercise the stress can cause the release of [[hormone]]s such as [[cortisol]] in order to quickly make available energy to the body. Cortisol forces [[Glycogenolysis|breakdown of glycogen]], protein (muscle) and fat deposits which are used in [[gluconeogenesis]]. Gainers seek to combat this effect after (and sometimes during) an exercise routine.

Higher glycemic carbohydrates will prompt a steep rise in blood glucose, forcing an equal release of [[insulin]] by the body to counter the longterm [[Hyperglycemia|negative effects of high blood sugar]], inhibiting the effects of cortisol. Some of the carbohydrates are immediately absorbed by the muscles without insulin. The rest is stored as [[glycogen]] in the liver and muscles.
