9 Best Collagen-Rich Foods
This article explores the best dietary sources of collagen, including animal and plant-based options. Learn how to incorporate these foods into your diet for improved skin health, stronger bones, and better joint function.

Collagen is an essential structural protein found in the tissue [1]. It is a key component of the bone, tendon, ligament, and skin. Collagen strengthens and structures connective tissue in the body.
In addition, it is useful for skin health and bone mineral and helps reduce joint pain. Collagen is produced when we consume protein-rich foods like fish, chicken, broth, and meat.
However, as we begin to age, our body produces a lower amount of collagen, hence the need to eat more collagen-rich food and collagen supplements.
If you have been looking to add food high in collagen to your diet, this article is for you. This article will explore different foods that are natural collagen sources.
What are Collagen-Rich Foods?
These are foods that are a rich source of collagen. They are mostly protein-rich foods that aid the production of collagen in the body.
These collagen-rich foods come in two types- Animal-based and Plant-based. In addition, foods that are rich in zinc also help with collagen production in the body. Examples of these foods are nuts, seeds, whole grains, leafy greens, and many more.
9 Natural Collagen Food Sources
Animal-Based Collagen-Rich Foods
Bone Broth
Bone broth is a nutrient-rich soup made from cooking animal bones, connective tissue, and certain meat. It has been available since the pre-historic times . The bones are simmered for an extended period for a greater concentration of collagen.
Some chefs use gravies, sauces, and soups as a base for the broth. There are different types of bone broth, namely chicken bone broth, beef bone broth, and pork bone broth.
Chicken bone broth is the most popular in the United States and contains a higher amino-acid content than beef broth.
Chicken
Collagen from chickens is derived from the bones, cartilage, and skin. Chickens are rich in Type II collagen; therefore, they are useful for joint health.
According to a 2021 study on adults aged 40–65 years to investigate the efficiency of hydrolyzed chicken collagen type II (HCII).
It was concluded that HCII can help reduce joint pain stiffness and also improve joint function in healthy adults.
Fish and Shellfish
Fish and Shellfish are a rich source of collagen. They are commonly referred to as marine-based collagen . This collagen source is gaining more attention as it is unique when compared with animal-based sources.
Marine collagen has a low molecular weight, no religious limit, and no disease transmission. The process of extracting marine collagen is cost-effective compared to other sources. In addition, this collagen is easy for the body to absorb.
Eggs
Eggs are a rich source of protein, and they aid in the body's collagen production. There are two types of collagens found in the two layers of an egg, Type I and V .
Collagen is found in the thin inner and the thick outer membrane of an egg. In addition, collagen is present in the yolk of chicken eggs. More than 90% of the collagen found in the body is Type I. Type V is equally important for the body. This means eggs are a great source of collagen.
In addition, eggshell membranes also aid collagen production and increase cellular activity in the body.
Plant-Based Collagen-Boosting Foods
Leafy Greens
Leafy Greens serve as a source of vitamins and nutrients that aid the production of collagen in the body. Examples of leafy greens include Collard greens, kale, Spinach, Swiss chard, and Mustard green.
These leafy greens are known to contain nutrients that help to reduce the degradation of collagen and the production of collagen in the body.
For example, a clinical study conducted by Meinke et al. (2017), where volunteers were supplemented with a carotenoid-rich natural kale extract, concluded that kale may prevent the degradation of collagen caused by aging .
Citrus Fruits
Citrus fruits like orange, lime, lemon, and grapefruits help aid the production of collagen in your body. This is because they are rich in vitamin C.
According to a preclinical study, vitamin C is concluded to exhibit the potential to aid bone healing and increase the production of type I collagen . Aside from helping with collagen synthesis, vitamin C also helps stabilize mRNA to increase collagen synthesis for skin repair.
Berries
These are also a good source of vitamin C; therefore, they help in collagen synthesis. Berries like strawberries, blueberries, raspberries, blackberries, and cranberries are good sources of vitamin C, so they can aid collagen production in the body.
According to research published in the National Library of Medicine, berry extracts contain bioactive compounds that have positive effects on tissue regeneration, promote wound healing, and also stimulate collagen synthesis.
Garlic
Garlic is also a plant-based collagen-boosting food that is known to help improve skin health. This is a result of its sulfur content, which can help with collagen synthesis and prevent collagen degradation.
In addition, research published by the National Library of Medicine also concludes that garlic contains anti-oxidant effects that may help reduce the degradation of dermal collagen.
Nuts and Seeds
Nuts and seeds contain essential nutrients. They are packed with nutrients like amino acids, healthy fats, selenium, and zinc, which are important for collagen synthesis. Most especially, zinc helps to regenerate and repair the skin.
Examples of nuts and seeds are almonds, chestnuts, peanuts, walnuts, hazelnuts, sunflower seeds, and many more.
Almonds are a rich source of vitamin E. This vitamin E has the potential to prevent collagen degradation. Therefore, adequate consumption of almonds can prevent signs of skin aging like facial pigmentation and wrinkles.
How much Collagen do High-collagen Foods Contain?
Source | Serving size | Amount of collagen |
---|---|---|
Bone broth | 1 cup | 5 – 12 g |
Chicken | 1 chicken drumstick | 107 mg |
Fish and Shellfish | 50g | 0.1 - 0.7 g |
Meat | 100g | 1 – 3g |
Gelatin | 50g | 50g |
Collagen-rich Foods vs. Collagen Supplements
As discussed above, collagen-rich foods are essential for the production of collagen in the body. In addition, these foods contain different nutrients that are associated with the synthesis of collagen in the body. So, as you begin to age, these foods will help ensure you maintain a healthy collagen level in your body.
Are collagen supplements a better option?
It is very improtnant to know how much collagen to take? & collagen supplements are also a reliable resource to help maintain collagen levels in the body. They are mostly in hydrolyzed form, so the body easily absorbs them.
It has gained popularity over the years because it is convenient to use. In addition, it is easier to keep up with collagen supplements in your routine than collagen-rich foods in your diet.
Collagen-rich Foods
These are foods containing collagen. Consuming this food will help improve collagen levels in your body. Examples of these foods are chicken, bone broth, beef, pork, and fish. However, some foods are not a direct source of collagen; they contain nutrients that can aid the synthesis of collagen.
Few of these foods contain vitamins, zinc, amino acids, and healthy fats that help collagen production. One of the best things about collagen-rich food is bioavailability. They are mostly rich in collagen form that the body can use immediately.
Collagen Supplements
Collagen supplements are an easy and quick way to maintain your collagen level. These supplements are a component of collagen that has been broken down so it can be absorbable by the body. They are known as hydrolyzed collagen. These collagen supplements are available in powder or pill form. The powder form can be mixed with smoothies, beverages, shakes, food, or sauces.
They do not only contain collagen; these supplements also contain short chains of amino acids known as peptides and keratin. In addition, they can be added to cosmetic products in the form of powder or cream. These supplements are also useful for improving skin, bone, and joint health.
Final Thoughts
Since aging reduces collagen levels in the body, there is a need to focus more on collagen-rich foods to maintain collagen levels. Animal sources are mostly the richest in collagen since they are mostly a direct source of collagen.
Also, marine collagen is the safest since there is no risk of disease transmission. Some plant-based foods are not a direct source of collagen; however, they contain nutrients that help with collagen synthesis.
Irrespective of the collagen source you prefer, they will all help aid collagen production and also prevent its deficiencies. Lastly, collagen-rich foods are more important than supplements; however, there is an increased demand for collagen supplements because they are easily accessible.
