Want firmer-looking skin, better elasticity, and healthier connective tissue? Collagen plays a major role in all of them—but your body does not make the same amount of collagen forever.
The amount of collagen your body produces can decline over time, and factors such as sun exposure, diet, lifestyle habits, and skincare can influence how quickly collagen is produced and broken down.
The goal isn’t to chase exaggerated “collagen-boosting” claims. Instead, here are practical, evidence-based ways to support your body’s natural collagen production.
What Is Collagen?
Collagen is the body’s main structural protein, helping give tissues such as skin, bones, tendons, ligaments, and cartilage their strength and structure. There are many types of collagen, with types I, II, and III among the most abundant.
- Type I: Found mainly in skin, bones, teeth, tendons, ligaments, and blood vessels.
- Type II: The main type of collagen found in cartilage.
- Type III: Found in muscles and blood vessels, where it often works alongside type I collagen.
As you age, collagen production decreases and existing collagen becomes more fragmented, contributing to changes such as thinner, less resilient skin and the formation of wrinkles.
How to Increase Collagen Production Naturally
Your body cannot simply switch collagen production back to its younger levels, but it still has the machinery to make collagen. Giving it the amino acids and nutrients involved in collagen synthesis—and reducing factors that accelerate collagen breakdown—can help support this process.
1. Eat Enough Protein
Collagen is a protein, so your body needs amino acids to build it, particularly glycine and proline, which are abundant in collagen.
Getting enough protein from your diet provides the building blocks your body uses to produce collagen and maintain other tissues. This does not mean you need to eat large amounts of protein, but consistently falling short of your protein needs can make it harder for your body to maintain tissues properly.
Good protein sources include:
- Eggs
- Fish
- Chicken and other lean meats
- Greek yogurt and other dairy foods
- Soy and tofu
- Beans and lentils
- Nuts and seeds
Try to include a protein source in your main meals rather than relying on one high-protein meal at the end of the day.
2. Eat More Vitamin C-Rich Foods
Vitamin C is essential for collagen production. It may also help protect existing collagen from breaking down.
You don’t need an expensive supplement to get enough vitamin C. Many fruits and vegetables can provide plenty of this nutrient.
Good food sources include:
- Guava
- Oranges and other citrus fruits
- Kiwi
- Strawberries
- Bell peppers
- Broccoli
- Tomatoes
- Indian gooseberry (amla)
Adding a vitamin C-rich food to your meals is a simple way to get this nutrient as part of a balanced diet.
3. Include Foods That Provide Zinc and Copper
Collagen production involves more than protein and vitamin C. Several minerals also contribute to normal connective-tissue formation.
Zinc and copper support collagen production, but they may do more than help your body make collagen. Zinc may also help protect collagen from breakdown by inhibiting enzymes called matrix metalloproteinases (MMPs) that can degrade it.
Moreover, zinc plays a role in tissue repair, while copper helps strengthen collagen and elastin by supporting the cross-linking that helps stabilize these proteins.
You can find these nutrients in foods such as:
Zinc: Meat, shellfish, dairy products, beans, nuts, and seeds.
Copper: Shellfish, nuts, seeds, whole grains, beans, and dark chocolate.
Rather than focusing on one “collagen-boosting” food, aim for a varied diet that provides a broad range of vitamins and minerals.
4. Eat Foods That Naturally Contain Collagen
Some animal foods contain collagen because they contain connective tissue. Bone broth, gelatin, chicken skin, fish skin, and cuts of meat containing connective tissue can provide collagen or collagen-derived proteins.
However, eating collagen does not mean that the collagen travels directly to your skin.
Your digestive system breaks dietary collagen down into amino acids and smaller peptides, which your body can then use in different ways.
So, collagen-containing foods can contribute to your overall protein intake, but they don’t automatically tell your skin to produce more collagen.
5. Protect Your Skin from Excessive Sun Exposure
If you are serious about maintaining collagen, sun protection deserves just as much attention as what you eat.
Ultraviolet radiation can damage collagen and contribute to its breakdown in the skin. Over time, repeated UV exposure can contribute to wrinkles, loss of elasticity, uneven skin texture, and other signs of premature skin aging.
You can reduce unnecessary UV exposure by:
- Using broad-spectrum sunscreen
- Wearing protective clothing
- Seeking shade when the sun is strongest
- Wearing a hat and sunglasses outdoors
- Avoiding intentional tanning
You cannot stop UV exposure completely, but reducing cumulative damage can help protect the collagen you already have.

6. Don’t Smoke
Smoking is another habit that can work against healthy collagen.
Chemicals in cigarette smoke can increase oxidative stress and interfere with collagen production and repair. Smoking can also slow wound healing and accelerate visible signs of skin aging.
In fact, a study comparing smokers and nonsmokers found that smokers had 18% lower type I collagen production and 22% lower type III collagen production. They also had higher MMP-8 levels, suggesting smoking can reduce collagen production and disrupt normal collagen turnover in skin.
If you smoke, quitting can benefit far more than your skin. It can improve your overall health while removing one of the factors that can work against healthy collagen.
7. Consider Retinoids for Skin Collagen
If your goal is specifically to support collagen in your skin, skincare can also play a role.
Retinoids, including retinol and prescription retinoids, have been widely studied for photoaged skin. They can stimulate collagen production and improve signs of photoaging.
For instance, a review of seven trials found that topical tretinoin can stimulate new collagen formation and improve wrinkles, uneven pigmentation, sallowness, and age spots, with benefits reported from one month through 24 months.
While retinoids can also increase collagen and elastic fibers in the skin, stronger prescription retinoids may cause dryness, peeling, redness, and burning or stinging.
If you’re new to retinoids, starting gradually can help your skin adjust. Prescription retinoids should be used according to medical guidance.
8. Eat a Diet Rich in Antioxidant-Rich Foods
Oxidative stress can contribute to damage to skin structures, including collagen.
You cannot completely eliminate oxidative stress—and you do not need to. Instead, focus on regularly eating a variety of foods that provide antioxidants and other protective compounds.
Colorful fruits and vegetables are especially useful. Berries, citrus fruits, leafy greens, tomatoes, peppers, carrots, and other plant foods provide different combinations of vitamins, minerals, and plant compounds.
Think variety rather than searching for one “best” antioxidant food.
9. Limit Excessive Alcohol
A few drinks now and then aren’t the same as regularly drinking heavily. The concern is what happens when high alcohol intake becomes a habit: it can interfere with nutrition and contribute to deficiencies in important vitamins and minerals.
Your skin also has to repair and maintain its tissues constantly. Heavy alcohol exposure can interfere with processes involved in tissue injury and repair, including matrix regeneration.
Over time, heavy alcohol use has also been linked with oxidative stress, inflammation, and changes associated with premature skin aging.
So, rather than trying to offset heavy drinking with collagen supplements, focus on keeping alcohol intake moderate and giving your body the nutrients it needs to support healthy skin.
10. Consider Collagen Peptide Supplements
Collagen peptides are one of the most popular ways people try to support collagen-related skin benefits.
Unlike whole collagen, collagen peptides are broken into smaller chains of amino acids and peptides that can be digested more easily.
A 2023 meta-analysis of 26 studies found that hydrolyzed collagen supplementation improved measures of skin hydration and elasticity.
However, the evidence is not completely consistent. A 2025 meta-analysis found that these benefits were not significant when researchers focused on higher-quality studies or studies without pharmaceutical-company funding.
So, collagen supplements may be worth considering, but they should not replace the basics. A balanced diet, adequate protein, sun protection, and appropriate skincare remain important for maintaining healthy skin.
Can You Increase Collagen Production After 30?
Yes, your body continues to produce collagen throughout adulthood.
However, collagen production naturally declines with age, and collagen breakdown can increase due to factors such as UV exposure and other forms of environmental stress.
You cannot completely restore collagen production to the levels you had when you were younger, but you can support the collagen your body continues to make.
Protecting your skin from UV radiation, eating enough protein and vitamin C, avoiding smoking, and using evidence-based skincare can all help maintain the structure and appearance of your skin over time.
Does Drinking Collagen Increase Collagen Production?
Collagen drinks and supplements provide collagen peptides rather than sending intact collagen directly to your skin.
Some studies suggest that consuming hydrolyzed collagen may influence skin hydration and elasticity, potentially through the absorption of collagen-derived peptides and the availability of amino acids.
But the evidence is still evolving, and not everyone will experience noticeable results.
If you decide to use a collagen supplement, look for a product that clearly states the type and amount of collagen it contains. Consistent use matters more than taking it at a particular time of day.
Takeaways
You cannot completely stop the natural decline in collagen that happens with age, but you can support your body’s ability to make and maintain it.
Start with the basics: eat enough protein, get plenty of vitamin C-rich foods, protect your skin from UV exposure, don’t smoke, and take care of your skin. If you are interested in collagen supplements, understand that the research is promising in some areas but still mixed.
The goal is not to chase a single “collagen-boosting” food or product. It is to create the conditions your body needs to maintain healthy skin and connective tissue for as long as possible.
