What Is Whey?

Whey protein is the benchmark standard for those wanting to consume more protein and build muscle. Whey is a milk-based product with a large amount of protein and minimal amounts of fat, carbs, and lactose.

Why Do People Take Protein?

Protein supplements can be beneficial for almost everyone. Protein powders are commonly used by athletes, gym goers, anyone to improve their health and well-being. Protein can help with meeting your daily dietary requirement. It can help build muscle, lose weight, recover faster, and it's convenient to consume before or after a workout.

Why Choose Whey Concentrate?

Whey typically comes in three versions: concentrate, isolate, and hydrolyzed. Whey concentrate is the least processed and contains around 80% protein with the remaining consisting of carbs and fats. It also contains more bioactive compounds such as growth factors (IGF-1), which are hormone-like peptides that stimulate cell growth and repair; peptides, which are short chains of amino acids that help breakdown of whey proteins; and immunoglobulins, which are antibodies help with immune function.

Whey isolate is more processed, contains around 90% protein content, and generally costs more. Isolate is for those who are looking for less carbs and fat in their protein or have an intolerance to lactose.

Hydrolyzed contains the same protein content as isolate but is even more processed and therefore even more expensive. Hydrolyzation pre-digests the protein into smaller peptides to help athletes digest and absorb protein faster. This protein is designed for those who need protein as quickly as possible.

Many athletes choose a whey protein over soy, casein, or pea protein because it is faster absorbing, quicker digesting, and it produces a more rapid response on protein synthesis.[1] Whey protein is a complete protein with high levels of the essential and branched chain amino acids that can be readily used by the body. Whey has the highest per gram/hour absorption rate with 9 grams as opposed to casein with 6 grams, soy with 4 grams, and cooked eggs with 3 grams.[2] This quick absorption can lead to higher amino acid availability and therefore greater ability for protein synthesis and overall muscle growth.[3]

Why Choose Signature Whey?

Bodybuilding.com Signature 100% Whey combines all three types of whey: concentrate, isolate, and hydrolyzed. This gives you the benefits each has to offer. It has 25 grams of protein, 2 grams of carbohydrates, and 1 grams of fat per 32 gram scoop. It also has 11.9g of essential amino acids (EEAs) and 5.5g of branched chain amino acids (BCAAs), as well as digestive enzymes to help break down and absorb the protein more efficiently.

Why Take Protein After a Workout

The post-workout consumption of whey has been extensively shown to increase muscle strength, size, performance while also helping decrease muscle soreness and body fat.[5] The rationale behind its effectiveness is the high amount of leucine, which has specifically shown to greatly impact protein synthesis and muscle growth.[6] One 30-gram scoop of whey protein has approximately 3 grams of leucine which has shown to trigger an anabolic response.
