If you’re trying to shed a few extra pounds, you may have heard that increasing protein in your diet can help you stay full and reduce cravings. But, what about collagen? Collagen is a type of protein as well, but does it have the same effects as other types of protein? Learn more about this protein and how collagen supplementation may help.

What Is Collagen?

Collagen is a protein found in the connective tissue of mammals. As we age, we start to lose the protein as our collagen production slows down. The loss of this structural protein can result in loss of skin elasticity, wrinkles, and creaky, achy joints.

Collagen peptide supplements come in powdered or capsule form and can be used to help slow the decline of collagen protein in the body. Supplementing collagen peptides may help improve the appearance of skin and keep joints healthy. But since collagen peptides are a type of protein, they may have other health benefits as well.

Will Collagen Help You Lose Weight?

Besides the benefits of collagen intake on skin elasticity and joint health, a collagen peptide supplement may also have an effect on weight loss. Although there haven’t been many studies on collagen peptides and weight loss, some emerging research indicates they might help you lose weight in a number of ways. In a small 2019 study, 90 volunteers with an average body mass index of 25.6 were given either 2,000 mg per day of collagen or a placebo. After 12 weeks, those who received the collagen peptide supplements showed significant improvements in body fat percentage and body fat mass.

A 2018 animal study found similar results. Mice were fed a high-fat diet and supplemented with various amounts of collagen peptides. Those that received the collagen peptides were found to have improved fat metabolism and less stored body fat overall.

A 2008 study provided 24 adults with different types of protein supplements at two breakfast meals. The first meal consisted of either alpha-lactalbumin, gelatin or gelatin with tryptophan. The second meal had soy, casein and whey or whey with glucagon-like peptide. They found that after the first breakfast, those who consumed the meal high in gelatin — a less broken down version of collagen — reported a 40% increase in satiety, or feeling of fullness. The subjects that received the gelatin also ended up consuming fewer calories for lunch. This research suggests that eating meals that include collagen may help you eat less overall, helping you lose weight.

Collagen protein may also help you maintain healthy weight indirectly, by increasing lean muscle mass and keeping the joints fluid and flexible. So, how does collagen build muscle? Collagen has been found to boost lean body mass and strength in older adults. More muscle speeds up metabolism, so you burn more calories even at rest. Additionally, if you have pain-free joints, you are more likely to exercise, which could help you maintain a healthy weight.

Although there haven’t been many direct studies on the relation of collagen levels, collagen supplements and weight loss, there are several potential ways it could help you maintain a healthy weight.

How to Use Collagen For Weight Loss

At this time, there is no specific recommended dosage for how much collagen is needed to lose weight. Collagen supplements, such as collagen powder and liquid collagen,  can be added to your diet just like any other protein supplement. Taking a collagen supplement is a simple way to boost protein intake, in addition to eating other high-protein foods, to help you eat fewer calories.

Other Benefits of Collagen

Beyond supporting your weight loss journey, adding a collagen supplement to your diet can have many other benefits. Consuming collagen helps to preserve healthy hair, skin, and nails since it is an essential factor in skin composition, giving it elasticity and resilience. Additionally, collagen plays a vital role in the function and structure of cartilage, the tissue that surrounds joints, and decreases joint pain and rigidity. Increased collagen consumption can help to support and alleviate joint pain and discomfort. This study in 2022 even found that collagen may improve gut health and digestive symptoms.
