Due to the large range of protein supplements available, it’s easy to get confused when choosing the most appropriate protein powder to help you achieve your goals. To clear up the confusion, let us give you an overview of the main differences between each protein powder and provide advice on the best time to take them.
Different protein sources have different rates of absorption
Once a protein shake is ingested, the protein molecule is broken down into amino acids or small peptides in a process called “proteolysis”. After proteolysis, the amino acids and the small peptides are able to enter the bloodstream and become available for muscle protein synthesis.
This whole process takes a certain amount of time which varies according to the protein source. Some proteins are absorbed quickly by the body and others take longer to enter the bloodstream. Whey protein powders have the fastest absorption rate known to man which makes them especially useful for post-workout, when your body is hungry for nutrients (especially protein).
On the other hand, casein is known for its slow digestion and is therefore a great protein to have before you go to bed. Casein provides a gradual release of amino acids into the bloodstream (up to 7 hours), preventing muscle catabolism and increasing protein synthesis.
Other advantages of different protein sources
There is more to choosing protein sources than just the rate of absorption. Some people simply can’t take certain protein supplements due to allergies or intolerances. Whilst some are partially or completely allergic to milk proteins (lactose), others struggle to tolerate soy proteins. Naturally, these people must choose an alternative protein source such as egg protein as a replacement for whey protein.
For those who prefer non-animal protein sources, we also provide a wide range of high quality of protein powders such as Pea Protein, Brown Rice Protein or Hemp Protein. These protein powders have a quality amino acid profile and can help you meet your daily protein requirements.
