Hello! Wednesday is our day for learning.

Collagen powders promise smoother skin, stronger joints and better recovery from exercise. When one supplement is supposed to help with so many things, a natural question arises: how much of this is actually proven? Food and biotechnology student Anette Auväärt reviewed the research on skin, joints, muscles and tendons separately.

One fact to take away

The collagen you consume does not travel unchanged straight to your facial skin or knee cartilage. During digestion, it is broken down into amino acids and short peptides. Some peptides do reach the bloodstream, but whether they benefit the skin or joints needs to be demonstrated in separate studies.

What did the higher-quality skin studies conducted independently of manufacturers show? Is collagen better than whey protein for muscle growth? And which five questions should you ask yourself before adding a tub of collagen to your shopping basket? You will find the answers on the blog, and at the end of the article you can earn one knowledge point by answering review questions.
