What are Whey Peptides?

Whey peptides are short chains of amino acids derived from whey protein.

Whey peptides are commonly found in various sports nutrition supplements, including protein powders, protein bars, and ready-to-drink shakes.

How are Whey Peptides obtained?

Whey peptides are a component of hydrolyzed whey – the pre-digested form of whey, and are obtained through enzymatic hydrolysis, a process that breaks down the larger protein molecules into smaller peptides. These peptides are often touted for their faster absorption rates compared to intact proteins, making them popular among athletes and fitness enthusiasts for post-workout recovery.

What are the Benefits of Whey Peptides?

Over 70 percent of nitrogen found in the bloodstream is in peptide form. When the body breaks down proteins, it breaks them down into peptides, which in turn creates nitrogen in the bloodstream.

Peptides are absorbed over 200 percent faster than free-form amino acids or whole protein molecules, and are over 65 percent better at retaining nitrogen than regular whey. The faster protein is absorbed in the body, the more it promotes protein synthesis – a key component in muscle development.

Other valuable characteristics of Whey Peptides

Enhanced Immune Function: Some studies suggest that whey peptides may boost the immune system and help to protect against infections.
Improved Blood Pressure: Whey peptides may help to lower blood pressure in people with high blood pressure.
Weight Management: Whey peptides may help to promote feelings of fullness and reduce appetite, which could lead to weight loss.
Muscle Development: Peptides stimulate Insulin Growth Factors, which develop muscle tissue.
Gastrointestinal Function: Whey peptides may act as prebiotics and nourish the good bacteria in your gut, and are also recommended for individuals with lactose intolerance and very sensitive digestive systems.
Liver Function: Whey peptides may help to improve the liver’s ability to detoxify the body by increasing the production of glutathione, an important antioxidant.
