The information we constantly receive about the qualities of collagen supplements has meant that this protein has many followers but also many detractors. It is therefore common to hear the phrase "taking collagen is useless".

This statement, which we have even heard from health professionals, has sparked debate about the effectiveness of collagen supplements despite the fact that they are backed by clinical trials.

The widespread belief that collagen supplements are useless is based on a lack of understanding of the mechanism of action of these compounds in our bodies.  There is a misperception that these supplements contain collagen protein directly, ready to be absorbed and generate instant benefits. In reality, collagen supplements rely on the action of peptides during digestion, which may lead to the hasty conclusion that collagen itself has no effect.

Collagen peptides: the key to the process

Collagen protein is too large to be easily absorbed by the body. Collagen peptides are fragments of this protein, obtained by the process of hydrolysis. It is precisely these peptides that are responsible for promoting collagen synthesis in the body, which in turn benefits the health of the skin, joints and connective tissues. Collagen does not work, it is its peptides that do, and certainly not automatically. The benefits of these products manifest themselves over the long term and are closely linked to a healthy lifestyle, which includes a balanced diet and healthy living. 

Collagen supplements for overall well-being

As we age, natural collagen production declines, which can lead to problems such as wrinkles, sagging skin and joint deterioration. It is in this context that collagen supplements are needed to provide the necessary elements for this internal synthesis.

The key to properly assessing the efficacy of collagen supplements lies in understanding their mechanism of action and their contribution to overall well-being. While it is true that taking collagen directly does not produce the desired effects, the option of ingesting collagen peptides, especially in hydrolysed form, will help to maintain skin health in the short to medium term and joints and connective tissues in the long term.

Once you understand how collagen protein and its peptides work, you can make the most of their benefits to promote optimal long-term health and wellness. But not everything goes when it comes to collagen supplements.

Understanding how peptides work is only the first step in selecting truly beneficial supplements. It is very important to look at the composition, the active ingredients and it is very important that it is backed by clinical trials.

Nutricosmetics is at a point of constant innovation, and collagen supplements are booming. Keeping yourself informed and knowing how they work will be the key to your choice and, therefore, to their effectiveness.
