Collagen and weight gain: is there a link?

---

Collagen is the most abundant protein in the human body, accounting for approximately 30% of the body's total protein. It plays a key role in the structure of skin, bones, joints, and tendons. Contrary to popular belief, collagen consumption does not lead to weight gain: it is a protein naturally low in carbohydrates and fats, with no impact on fat mass. However, as a protein, it contributes to satiety and supports the structure of muscle tissue when combined with regular physical activity. Marine collagen, extracted from fish skin and scales, is particularly valued for its high bioavailability. Vitamin C contributes to the normal formation of collagen in the body — combining the two optimizes the benefits of the treatment. A daily dose of 5 to 10 grams, integrated into a balanced diet, is generally recommended for visible long-term effects.

"Take collagen? I'd love to, but it makes you gain weight, right?". If this phrase resonates with you... You are not alone! Today, collagen is an integral part of the beauty and wellness routines of pregnant women, new mothers, or those simply concerned about their bodies. But one question persists and comes up regularly: does collagen really lead to weight gain or is it a pure myth? In this article, we'll separate fact from fiction and help you finally see clearly so you can use this star protein without guilt.

What is collagen?

Let's start at the beginning: collagen is the most abundant protein in the human body. And we mean it! Because it represents nearly 30% of the total proteins present in the body.

Its role is not insignificant, as it helps ensure the cohesion, firmness, and elasticity of connective tissues. That is:

• skin;
• bones;
• joints;
• tendons;
• blood vessels;
• and ligaments.

Several types of collagen are distinguished. But types I, II, and III collagens are the most common:

• Type I collagen is particularly beneficial for the skin.
• Type II primarily affects articular cartilage.
• Type III, meanwhile, is often present alongside type I, especially in internal organs.

When we talk about collagen, it's hard not to think about marine collagen, which has been very popular for several years. Mainly extracted from fish (from their skin and scales), it is highly appreciated. Why? Because its high bioavailability allows for optimal absorption by the human body. Thus, it is an excellent alternative to naturally stimulate collagen production.

During certain important periods in a woman's life (such as pregnancy and postpartum), natural collagen production slows down. This results in the appearance of stretch marks or sagging skin after childbirth. An external intake of collagen can be fantastic for preserving beautiful skin and contributing to improved joint comfort.

Collagen and weight gain: is there a real link or is it a myth?

While the benefits of collagen for skin and joints are known, many question its potential impact on weight. So, can collagen really influence body shape? Let's clarify.

Does taking collagen make you gain weight?

Let's debunk the myth right away: no, taking collagen does not directly cause body weight gain (contrary to some misconceptions). Simply because collagen is a pure protein, naturally low in caloric intake. Therefore, it contains neither carbohydrates nor lipids in significant quantities. So, there is no physiological reason for its consumption to lead to an increase in fat mass!

So, where does this confusion come from? Probably from certain food supplements enriched with sugars or additives to improve their taste or texture. In this specific case, the additional caloric intake could lead to rapid weight gain and fat accumulation. But, let's be clear: this remains independent of the collagen itself.

Collagen is therefore appreciated for its role in supporting skin suppleness and joint comfort without side effects on weight. On the contrary, those who seek to regulate themselves should take a closer look at this molecule!

Collagen and weight gain: does collagen facilitate muscle mass gain?

Yes, collagen can contribute to muscle mass gain, but indirectly. It must be combined with regular physical activity to unleash its full potential. Why? Because it is a structural protein, meaning it plays a key role in the maintenance, resistance, and regeneration of muscle fibers.

Specifically, collagen aids in post-exercise recovery, which can promote performance and muscle growth in the long term. However, it does not cause rapid muscle hypertrophy, as other more targeted proteins, such as whey protein, can.

This is particularly relevant for athletes. Or for postpartum recovery for women looking to regain muscle tone and strength!

Does collagen help with weight loss?

In itself, collagen does not have direct fat-burning or slimming properties. However, its role in the overall process of weight loss should not be overlooked! Because it can be complementary, particularly thanks to its satiating effect. And yes, again... It's a protein. And a good protein intake encourages a feeling of fullness. So, when consumed:

• it naturally regulates appetite;
• it reduces cravings for snacks between meals;
• it limits calorie absorption.

Furthermore, collagen can play an indirect role in weight loss because it contributes to the structure of body tissues. By maintaining their structure and good tissue support, it helps prevent skin sagging, a common phenomenon after significant weight loss. Particularly beneficial for women after pregnancy who wish to regain firm and toned skin!

However, don't expect miracles by consuming "just" a little collagen every day. If you want results, you'll need to combine your collagen intake with a healthy diet and regular physical activity. Because it can support and boost the beneficial effects of a healthy lifestyle.

Recommendations to follow when taking collagen

Want to start a collagen treatment? Great news! To fully benefit from collagen without fear of weight gain or unwanted side effects... Follow our recommendations!

Choose an appropriate form of collagen

First, we advise you to choose a form of collagen adapted to your needs. For example, by opting for marine collagen. Sourced from fish bones and scales, it's our favorite at Boome and the one we've carefully selected for our Beauty Potion! Our marine collagen powder is ethically sourced, made in France, and very well assimilated thanks to its low molecular weight.

Prioritize (good) food supplements

Next, make sure to choose a high-quality collagen supplement. Prefer natural formulations, without added sugars or superfluous additives. It should also have a low molecular weight. If you can, also check the purity labels as well as the origin and extraction method of the collagen.

Take the (right) daily dose of collagen

To obtain visible (and lasting!) results, a daily intake of between 5 and 10 grams is recommended. However, regularity will remain your best ally: beneficial effects generally appear after several weeks of regular intake.

Pamper your diet

We repeat: your collagen treatment will only be optimal if you integrate it into a balanced diet. And especially if you add foods rich in vitamin C to your plates. Because it facilitates its assimilation and naturally stimulates its production by the body. This is the time to indulge in:

• red fruits;
• fresh vegetables;
• citrus fruits.

Conversely, eliminate unbalanced diets and ultra-processed foods!

In summary, there is no direct link between collagen intake and undesirable weight gain. On the contrary, if you integrate this protein into an appropriate wellness routine, all you risk... is regaining beautiful skin and amazing muscles. Not bad, right? The essential, however, remains to choose quality collagen. And, of course, to respect the usage recommendations to maximize its benefits. So, go for it!
