Examining the evidence Can the intake of collagen result in an increase in body weight?

Collagen is a collection of proteins that act as a crucial fundamental element of the organism, utilized for various functions ranging from the maintenance of dermal and pilous health to the improvement of joint and ligament pliability.

Our diet does not supply much collagen because it is mainly present in plant and animal parts that are not commonly ingested, and its disintegration and assimilation into the body are arduous. As a consequence, individuals consume collagen supplements or incorporate collagen adjuncts into their diet to enhance their collagen ingestion.

Nevertheless, a widespread misapprehension is that heightening collagen intake may instigate an upsurge in body mass. Contrarily, this is not factual, and in point of fact, it might obliquely facilitate weight reduction.

Facilitating the development of lean muscle mass

Collagen development of lean muscle mass

Augmenting the quantity of collagen in your system elevates your capacity to foster lean muscle tissue. However, merely ingesting collagen would not suffice in building muscle, but it could amplify the outcome of your physical exertion.

Fabricating more muscle tissue facilitates weight loss since muscular tissue necessitates more calories to sustain compared to adipose tissue. Therefore, your physique could incinerate a larger amount of calories ingested and convert body fat to calories. In some instances, constructing muscle could result in weight gain as muscular tissue outweighs fat. Nevertheless, this is not an unwholesome form of weight gain.


Collagen is a protein variant. Protein consumption yields a feeling of fullness after ingestion and sustains satiety for a prolonged period after a meal. Therefore, collagen supplementation can deter overindulging by curbing your hunger pangs amid mealtimes.



Collagen constitutes a crucial element of the cartilage and ligaments within our joints. Collagen supplementation can enhance your flexibility and alleviate joint aches by assisting in the mending of these tissues.

Albeit promoting joint mobility does not explicitly support weight loss, joint stiffness or pain could serve as a significant hindrance to exercising for numerous individuals. Addressing these concerns could enable you to partake in more physical activities, thereby facilitating weight management and bolstering overall well-being.


Collagen is a significant component that helps maintain the toughness and density of your bones. As one ages, their innate collagen synthesis declines, causing their bones to become less dense and lighter in weight. Ingesting collagen supplements can replenish your bone density, which can result in weight gain due to denser and subsequently heavier bones.

Are there any adverse effects associated with the consumption of collagen?

One of the most common effects of consuming collagen is a reduction in appetite or a feeling of increased fullness after meals, although this can vary depending on the individual.

It is important to note that those with food allergies must be cautious about the source of the collagen, as it is frequently derived from allergenic foods like shellfish, fish, and eggs. Ingesting collagen supplements made from these sources can trigger an allergic reaction in individuals with corresponding allergies.

What are some effective ways to enhance my body’s innate production of collagen?

Here are some foods that can increase your collagen intake and boost collagen production:

  • Bone broth: Made by boiling bones and connective tissues, bone broth is rich in collagen and other beneficial compounds.
  • Meat: Beef, chicken, and fish contain high amounts of collagen.
  • Egg whites: Egg whites are a good source of proline and glycine, two amino acids that are important for collagen production.
  • Citrus fruits: Citrus fruits such as oranges and lemons contain high levels of vitamin C, which is essential for collagen production.
  • Berries: Berries such as strawberries, blueberries, and raspberries are rich in antioxidants that can help protect your skin from damage and promote collagen production.
  • Leafy greens: Leafy greens such as kale, spinach, and collard greens contain high levels of vitamin C and other nutrients that are important for collagen synthesis.
  • Garlic: Garlic contains sulfur, which is important for collagen production.
  • Avocado: Avocado is a good source of vitamin E, which can help protect your skin from damage and promote collagen production.
  • Nuts: Nuts such as almonds and cashews contain high levels of copper, which is important for collagen synthesis.
  • Beans: Beans such as black beans and kidney beans contain high levels of hyaluronic acid, which can help improve skin hydration and promote collagen production.


Chicken is a good source of collagen due to its high content. The stringy connective tissues that you see when you cut up raw chicken are primarily made up of collagen. Because of its high collagen content, chicken is often used as a source of collagen for supplements.


Eggs themselves do not contain collagen

Eggs themselves do not contain collagen, but egg whites are a good source of the amino acid proline. Proline is a building block that the body uses to produce collagen. Therefore, increasing your intake of proline can help boost your body’s natural production of collagen.


Consuming sources of vitamin C, such as citrus fruits like oranges, lemons, and grapefruit, can boost your body’s collagen production. Vitamin C plays a crucial role in the production of pro-collagen, which is a precursor to collagen that the body produces and later converts to collagen.


Garlic is a good source of sulfur, which the body uses to produce new collagen and help prevent the breakdown of existing collagen in the body. However, consuming too much garlic can cause an upset stomach or heartburn. Incorporating garlic into your regular diet in moderate amounts can provide health benefits, including maintaining your body’s collagen levels.


Beans are a great source of amino acids that are important for collagen production, such as proline and glycine. Additionally, beans also contain copper, which is a mineral that plays a key role in collagen synthesis.


bone broth is not a significant source of collagen

Contrary to popular belief, bone broth is not a significant source of collagen. While boiling animal bones can extract many nutrients, including some collagen, research shows that this process is not very effective in extracting collagen. However, bone broth is still a nutritious and healthy food.

It is important to note that even though some foods may contain collagen, they may not necessarily increase collagen levels in the body. This is because the body cannot use collagen directly from food. The collagen must first be broken down into amino acids that the body can use to produce its own collagen. Due to the difficulty of breaking down collagen, most of it passes through the digestive system without being absorbed.

What is the proper method of consuming collagen supplements?

Collagen hydrolysate, also known as collagen peptides, is a form of collagen that has been broken down into smaller, more easily digestible molecules. It is often used in collagen supplements as it is believed to be more bioavailable and effective than regular collagen. Gelatin is also a form of collagen that has been partially hydrolyzed and is commonly used in food products such as gummies and desserts.

Is it possible to mitigate the natural decline of collagen?

As we progress in age, our body’s capacity to produce collagen diminishes significantly. This inevitably leads to a reduction in collagen replacement ability, resulting in an inability to repair damaged collagen. To circumvent this situation, one must avoid certain practices that exacerbate collagen degradation and minimize collagen production, such as the following:

Overconsumption of saccharides and processed carbohydrates.

Consuming excessive amounts of sugar can impede your body’s natural process of repairing collagen. It’s crucial to monitor your intake of added sugar products and refined carbohydrates, which have the tendency to rapidly break down into sugar and raise blood sugar levels. This elevation in blood sugar levels can have a detrimental impact on collagen repair mechanisms.


Ultraviolet (UV) radiation can significantly decrease the production of collagen. This is particularly noticeable on the skin, leading to wrinkles and a decrease in elasticity. However, certain UV rays can penetrate the skin and affect deeper tissues, resulting in widespread damage to collagen production and other associated issues.


Smoking has numerous detrimental effects, one of which is a decrease in collagen production throughout the body. This can result in impaired wound healing and premature ageing of the skin.

Consuming collagen is a catalyst for enhancing one’s overall well-being.

Collagen supplements have a multitude of benefits beyond just enhancing skin health. These supplements can help to decrease body fat percentage when paired with regular exercise, although it may lead to a slight numerical increase in weight due to the development of lean muscle tissue and bone density, which is a positive outcome for overall health.


In conclusion, collagen plays a crucial role in maintaining the body’s health, and the reduction of collagen production can have a significant impact on our overall well-being. Avoiding certain practices such as consuming excessive amounts of sugar, exposing ourselves to ultraviolet radiation, and smoking can help to preserve collagen production. Collagen supplements are also beneficial and can contribute to the development of lean muscle tissue and bone density, leading to better overall health.
