The muscle mass increase was statistically significant but modest - averaging 0. Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost relative to meat and fish products , ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats.

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; [19] [20] [21] [22] [23] [24] [25] however there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance.

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. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:.

In addition, recent studies have also shown that creatine improves brain function. Creatine increases what is known as cell volumization by drawing water into muscle cells, making them larger. Creatine is sold in a variety of forms, including creatine monohydrate and creatine ethyl ester , amongst others.

Though all types of creatine are sold for the same purposes, there are subtle differences between them, such as price and necessary dosage. 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. Some studies have suggested that consumption of creatine with protein and carbohydrates can have a greater effect than creatine combined with either protein or carbohydrates alone.
