Proline is an amino acid, or a building block for protein, that is consumed in the diet or made by the body. It is involved in numerous body processes, including building muscle tissue, promoting collagen production, repairing skin damage, supporting the immune system, healing joints, improving antioxidant status, improving gut health, and protecting the cardiovascular system. Proline is primarily found in many animal-sourced foods, such as meat, fish, and dairy. It can also be taken as a supplement, which may be beneficial for those with a low-protein diet, chronic injuries, or mild to severe illnesses. Additionally, proline can be added to baked goods and smoothies to increase their protein content. While proline has many health benefits, some studies suggest that higher intake may be linked to depression.

What You'll Learn
Eat foods rich in protein
Proline is an amino acid, or a building block for protein. The body can make proline on its own, but it is also consumed in the diet. A typical diet contains about 5 grams of proline daily. The primary sources are protein-rich foods, including meat, fish, and dairy.
Proline is helpful for repairing damage to the skin, supporting the immune system, healing joints, improving antioxidant status, improving gut health and nutrient absorption, supporting the metabolism, and protecting the cardiovascular system. It is also used for skin healing, especially in people who have problems keeping enough proline in the body.
You can increase your proline intake by eating foods rich in protein, such as:
- Meat
- Fish
- Dairy
- Bone broth
- Chicken wings (with the skin)
- Pork rinds
- Gelatin
Proline is also found in collagen-rich foods, and collagen is made up of about 10% proline. You can add collagen powder to smoothies, desserts, or recipes with a gel-like texture, similar to how you would use gelatin.
In addition to eating protein-rich foods, you can also boost your proline absorption by eating foods that serve as "collagen cofactors". These include:
- Fresh vegetables
- Fresh fruits (especially those rich in vitamin C, such as oranges, lemons, and kiwis)
- Fresh herbs and spices
- Foods high in vitamin A, copper, and other amino acids like L-lysine

Consume vitamin C-rich foods
Consuming vitamin C-rich foods is essential, as our bodies cannot produce or store this vitamin. Vitamin C is necessary for normal growth and development and has protective qualities for our immune system and heart health. It also increases iron absorption and aids in wound healing.
To boost your vitamin C intake, focus on incorporating a variety of raw or uncooked fruits and vegetables into your diet. Some excellent sources of vitamin C include citrus fruits like oranges and strawberries, tomatoes, peppers, broccoli, and other vitamin C-packed produce available during the summer and early fall seasons.
You can also enhance your vitamin C intake by combining certain foods, such as pairing an orange with fortified breakfast cereal or enjoying strawberries with cashews or cashew butter. Additionally, some cereals and beverages are fortified with vitamin C, so be sure to check product labels to see how much vitamin C they contain.
While mild deficiencies in vitamin C are rare due to the wide availability of vitamin C-rich foods, it is still important to ensure adequate intake. Aim for a balanced diet that includes a variety of fruits and vegetables to meet your daily vitamin C needs and support overall health.

Eat healthy fats
Proline is an amino acid, or a building block for protein. The body can make proline on its own, but it is also consumed in the diet. A typical diet contains about 5 grams of proline daily. The primary sources are protein-rich foods, including meat, fish, and dairy.
When it comes to eating healthy fats to increase proline in the body, it is important to note that proline is not considered a nutritionally essential amino acid for humans who are otherwise healthy. However, it plays a crucial role in protein synthesis and structure, metabolism, and nutrition, as well as wound healing, antioxidative reactions, and immune responses.
To increase your proline intake through healthy fats, focus on consuming collagen-rich foods, as proline constitutes about 10% of the total amino acids in collagen. Bone broth, chicken wings (with the skin), pork rinds, and gelatin are excellent sources of collagen and, by extension, proline.
In addition to animal-based sources, you can also obtain proline from plant-based sources. For example, soy protein isolate is a good source of proline and can be incorporated into your diet in various ways, such as adding it to smoothies or using it as a meat substitute in recipes.
Another way to boost your proline intake is to consume foods rich in vitamin C, as this vitamin is necessary for the synthesis of collagen. Vitamin C-rich foods include peppers, cabbage, parsley, citrus fruits (oranges, lemons, grapefruit, etc.), and other fruits like bananas, mangoes, and melons.
By including a variety of healthy fats and vitamin C-rich foods in your diet, you can effectively increase your proline intake and reap the associated health benefits.

Eat essential nutrients
While the body can produce proline independently, it is also consumed in the diet. Proline is an amino acid, or a building block for protein. The body uses proline to make proteins, such as collagen, which is the most abundant protein in the body, making up about one-third of all the body's protein. Collagen is found in the skin, bones, and joints. It helps provide the structure for our skin, intestines, arteries, and all soft tissues in the body.
Proline is helpful for repairing damage to the skin, supporting the immune system, healing joints, improving antioxidant status, improving gut health and nutrient absorption, supporting the metabolism, and protecting the cardiovascular system. Proline is primarily found in many animal-sourced foods. The most important sources of proline are gelatin and the skins of animals. Other sources include meat, fish, and dairy.
You can also use collagen powder just like gelatin to thicken smoothies, desserts, or recipes with a gel-like texture. Make sure to purchase collagen powder derived from grass-fed or pasture-raised, healthy animals. You can boost the amount of proline you absorb by eating foods that serve as "collagen cofactors," such as plenty of fresh vegetables, fruits, herbs, and spices, various sources of "clean" protein, and foods high in vitamins C and A, copper, and vitamin B6.
Proline is likely safe when taken by mouth in food amounts. However, there is not enough information to know if proline is safe when used in larger amounts as medicine or applied to the skin.

Use progeline-based skincare products
Progeline is a powerful peptide that can help increase collagen production in the body, reducing wrinkles and improving skin elasticity. While there is limited independent research on the effectiveness of progeline-based skincare products, many sources claim that they can help combat signs of ageing, such as wrinkles, dullness, dryness, and loose skin.
Progeline-based skincare products, such as creams, serums, and lotions, are designed to be applied topically to the skin. These products are typically suitable for most skin types and can be purchased from various retailers, including online stores, cosmetics stores, department stores, and beauty shops.
When choosing a progeline-based skincare product, it is recommended to opt for higher-concentration formulas, as these are more likely to provide noticeable results. Additionally, some products may be more cost-effective than others, such as creating your own concentrated formula by adding progeline to an existing skincare product or purchasing inexpensive drugstore formulas.
While some experts argue that the effects of progeline in skincare products may not be significantly better than those of a good moisturiser, others claim that it can help uncover younger, brighter, and more supple-looking skin.
It is worth noting that, while progeline-based skincare products may provide anti-ageing benefits, a well-rounded approach to skin health should also include a healthy diet. Eating foods rich in antioxidants, healthy fats, and essential nutrients can help support skin health and protect against oxidative stress, a main cause of skin ageing.
