Whether you're an amateur or experienced athlete, you know it: gaining muscle mass and losing fat can impact your performance. It's no wonder you're paying attention to your diet and wondering if you might gain weight while taking a collagen supplement.

Indeed, collagen is a natural protein that provides structure to our bodies. Very abundant in the human body, collagen plays an essential role in the construction of connective tissues, including skin , tendons, ligaments, and cartilage. It is responsible for the strength and elasticity of these tissues, making it a key element for joint health and injury prevention during regular sports practice.

“Collagen peptides do not cause weight gain or mass gain. Therefore, it is best to combine your exercise with the intake of proteins from the AimeFit range, which boost performance and recovery ,” advises Claire Borwin, dietician and nutritionist. “On the other hand, collagen helps nourish tendons and ligaments, which maintains muscle resistance, strength, and mobility.”

The role of collagen in muscle mass gain

Better collagen quality can increase joint stability, allowing for heavier, more intense movements.

Stronger, more flexible tendons and ligaments can better anchor muscles to bones.

Taking collagen promotes recovery by helping to repair micro muscle tears caused by exertion.

Good idea: taking collagen from the age of 25, to compensate for the natural loss of 1% of collagen per year, can have real benefits in your sports practice.

Collagen and Weight Gain: What Should We Think?

Let's be clear, collagen doesn't make you fat. And remember, weight gain in itself isn't serious and can occur at any time in life following excesses, a change of pace, or a hormonal imbalance.

On the other hand, when you exercise, especially when you're weight training, you sometimes want to turn fat mass into muscle mass. This is what taking collagen in the form of dietary supplements allows you to do, helping to improve osteomuscular resistance and promoting recovery between sessions.

In addition to a course of marine collagen peptide powder, you can also include foods rich in collagen and nutrients that promote its natural production in your menu, as balanced and varied as possible.
