Collagen is a protein found in animal tissue such as muscle, skin, bones and tendons. It’s main function is to provide structure and support for tissues. Collagen provides structural strength without adding bulk or weight to the body. While it does not contain any amino acids, it does have other nutrients like vitamins and minerals that are beneficial for health.
Whey proteins are milk products containing both casein (milk protein) and whey (protein). They are made from two different types of milk: whole, skimmed or low fat. Whey contains all the essential amino acids needed for growth and repair.
Casein is used to increase the volume of milk solids so that they can be absorbed into the body better. Both whey and casein are very useful in making supplements because they do not require refrigeration, heat or other processing methods that may affect their nutritional value.
The composition of these proteins differ. Whey contains more leucine than casein, which is responsible for stimulating muscle protein synthesis. Casein has less glutamine than whey, which promotes recovery after exercise.
Whey contains more glycine than casein, which stimulates insulin secretion to promote energy storage during periods of starvation and prolonged fasting. Casein has a higher concentration of cysteines and threonine compared to whey. Cysteines are effective antioxidants that may protect the cells from oxidative stress and reduce the risk of heart disease.
When whey is separated from casein, it’s easier to digest and absorb. Whey also has a greater ability to promote muscle growth, while casein is more efficient at promoting muscle recovery and repair.
Why not take advantage of both by supplementing them into a single supplement?
