The 12 Best Collagen Supplements for Better Skin

Collagen is a type of protein found throughout your body, including in your skin, bones, joints, ligaments, tendons, connective tissue, and teeth (1).

Because collagen production starts to decline as you age, many people use supplements to help increase collagen levels naturally (2).

Sun exposure also contributes to collagen breakdown and can lead to unwanted wrinkles (3).

People often use collagen supplements to promote skin health, as this protein has shown benefits for skin elasticity, hydration, and texture (4, 5, 6).

However, not all collagen supplements are created equal, and collagen is available in several forms.

Collagen is most commonly derived from bovine, porcine, or marine sources. It can also be produced synthetically from insect, yeast, and plant or mammal cultures, resulting in a lower risk of allergic reactions (3).

Though bovine collagen is more widely found in supplements, marine collagen is believed to be better absorbed and less inflammatory and to contain fewer toxins (3).

We selected the products featured in this article based on the following criteria:

• Type of supplement: We included collagen supplements in various forms, including powders and capsules.
• Ingredients: We selected collagen supplements made with high quality ingredients, all of which are free of fillers and unnecessary additives.
• Third-party testing or certifications: Many of the products on our list have been tested or certified by a third-party organization to ensure safety and quality.
• Dosage: Most studies have evaluated the effects of collagen at doses of 2.5–10 grams (g) per day. We selected collagen supplements available in a wide range of doses, so you can adjust based on your needs (6).

When selecting a collagen supplement, there are several factors to consider.

First, it’s important to consider the type of supplement.

While some people prefer the ease and convenience of capsules, others enjoy the versatility of collagen powders, which can easily be mixed into beverages and baked goods.

You should also check the label to determine the dosage.

Although there are no established guidelines for how much collagen you should take, studies show that doses of 2.5–15 g of collagen peptides per day are considered safe and effective (13).

You may also want to read the ingredients label, as some products may contain additional ingredients to support skin health, such as silica, hyaluronic acid, and vitamin C.

Finally, be sure to opt for high quality supplements purchased from a reputable retailer and look for products that have undergone third-party testing to ensure quality and safety.

How long does it take for collagen supplements to start working?

The amount of time it takes to experience noticeable benefits after taking collagen supplements can vary. However, some research suggests that collagen supplements could improve skin elasticity and hydration within just 4–12 weeks (6).

What is the difference between regular and hydrolyzed collagen?

Hydrolyzed collagen has been broken down into smaller molecules. It may be easier for your body to digest and absorb than regular collagen (2).

Are collagen supplements safe?

Collagen supplements are generally considered safe and are associated with few negative side effects when used as directed (6).

However, to ensure safety, it’s important to purchase products that have been tested by an independent lab whenever possible. Additionally, be sure to consult a healthcare professional before adding any new supplements to your routine.

Are collagen supplements good for reducing wrinkles?

Some research suggests that collagen could help slow down signs of aging.

In fact, one review of 19 studies concluded that hydrolyzed collagen supplements could reduce skin aging, decrease wrinkles, and improve skin elasticity after 90 days (14).

Can collagen supplements help tighten saggy skin?

There is limited research on whether collagen can tighten skin. However, some studies have found that collagen supplements may improve skin elasticity, hydration, and texture, which could potentially improve the appearance of saggy skin (4).

Is there a vegan source of collagen?

Because collagen is derived from animal products, there are no vegan-friendly sources of collagen.

Some older research suggests that vegan collagen could be produced using genetically modified yeast and bacteria. However, more studies are needed and vegan collagen supplements are not yet readily available (15).

However, several vegan-friendly collagen-boosting supplements are already on the market. These usually contain ingredients that support collagen production, such as vitamin C.

Alternatively, you can consume more vitamin C-rich foods, such as fruits and vegetables, to help naturally promote collagen synthesis (12).

Is collagen keto-friendly?

Collagen can fit into a ketogenic diet, as it is typically low in carbs and high in protein. However, to keep your carb intake low, be sure to check the ingredients label carefully and opt for products without added sugar.

Taking a collagen supplement can be an easy and effective way to help promote better skin.

Plenty of products are available, containing a range of dosages and a variety of ingredients.

When deciding which supplement is right for you, consider the type of supplement, any additional ingredients, the dosage, and whether the product has undergone third-party testing.

As with any supplement, consult a healthcare professional before adding collagen to your treatment regimen, especially if you have any underlying health conditions.
