Can Collagen Cause Weight Gain?

We're often asked here at Absolute Collagen if taking additional collagen can make you gain weight - so we've put together a blog post to bust the myths and set the record straight!

One of the questions we often receive at Absolute Collagen is: can collagen cause weight gain? After all, since collagen is the most abundant protein in the human body, found in bones, hair, nails and more, surely adding more collagen to your body will cause you to gain weight?

Well, the short answer is no, collagen does not cause weight gain. The only way to gain weight is if you’re taking in more calories than you are burning, and collagen does not contain excessive calories. In fact, each Absolute Collagen sachet contains only 32 calories per 10ml serving.


Collagen is essentially a glue that holds the body together - in fact, its name comes from the Greek “kolla”, which literally means glue. It is found all across the body, including bones, skin, joint cartilage, nails and more.

But as well as acting like a glue, collagen also keeps your metabolism healthy to burn fat. And, as we get older, collagen levels naturally begin to deplete, with side effects including wrinkled skin, weight gain, and painful joints.

So, how does collagen relate to these side effects, and, in particular, what is the relationship between collagen and weight?

Does Collagen Help Build Muscle?

Collagen is a nifty little protein because it does so many things, but one of the main properties it has is the ability to build lean muscle. This, in turn, helps prevent excess fat and weight gain.

Absolute Collagen is a great post-workout boost, and lots of our Absoluters take it after their gym sessions to support their overall fitness routine, as it aids with the development and strengthening of muscle. So, while collagen cannot burn fat by itself, it plays a significant role in weight loss through building lean muscle when paired with regular exercise and a healthy diet.

As the glue of the body, collagen contributes to maintaining healthy, pain-free joints, which are essential for maintaining good levels of mobility and exercise. Joint pain can be a huge barrier to people wanting to work out and exercise more, and can contribute to unwanted weight gain as a result.

Absolute Collagen and Weight Gain

Taking Absolute Collagen will not make you gain weight, and in fact could support a healthy metabolism as part of a healthy weight-loss journey. Collagen is a protein, and has been scientifically proven to keep people feeling fuller and more satiated for longer. In a study of diabetic and overweight participants, hydrolysed collagen in the form of gelatin was proven to stimulate the release of satiating hormones into the bloodstream, helping the patients feel fuller for longer and reducing their appetite.

So rather than causing you to gain weight, collagen supplements have been shown to act as an appetite suppressant which helps reduce snacking and support healthy weight loss.

Plus, unlike some specifically weight-loss-promoting products, Absolute Collagen contains no fillers, binders, hormones, acids, forms of harsh processing or chemical sweeteners, and so it doesn’t interfere with the body’s natural rhythms and processes.

Absolute Collagen also has the added benefit of being cholesterol free! This is because we hydrolyse the raw material; essentially, this means it undergoes lots of filtration, which breaks down the molecules so we’re only left with collagen peptides and nothing else.

Does Collagen Help Reduce Cellulite?

Another aspect of weight gain Absolute Collagen can help with is the visible appearance of natural skin dimples, known as cellulite. This dimpled skin is often seen around the thighs, and although it’s a very normal feature of the human body, many people want to minimise its appearance and keep their skin looking as smooth as possible.

As part of a healthy weight loss process, Absolute Collagen can help with the smoothing of skin from the inside out, which can reduce the appearance of cellulite, as well as potentially helping to firm excess skin left behind after weight loss. This leaves skin smooth and more toned in appearance. This is because collagen contributes to the thickening and regeneration of skin, so it works on reducing cellulite the same way it works on reducing fine lines and wrinkles.

In conclusion, there is no need to worry about getting fat or gaining weight from taking collagen. And in fact, it In fact, collagen has several benefits that can even help with weight loss.

With just 32 calories per sachet, Absolute Collagen contributes to a healthy metabolism, builds lean muscle, supports joints to allow more exercise, and helps you feel fuller for longer, and can also help reduce the appearance of cellulite. These combined benefits help to support healthy weight loss and an overall level of wellbeing. Why not start taking Absolute Collagen today and let us know what benefits you notice?
