Quick Health Scoop

  • Collagen is an abundant protein that the body naturally produces
  • Since collagen makes up about 90% of your hair, skin, and nails, collagen benefits may include helping to support healthy hair, skin, and nails
  • Starting in your 20s, your body produces less collagen
  • With no known side effects, the benefits of taking collagen supplements might be worth considering, especially as you age
  • Verisol® collagen peptides was clinically studied to help reduce fine lines and wrinkles around the eye in as little as 4 weeks and support healthy skin and elasticity§†

Did you know that collagen (types I and III to be exact) makes up about 90% of your hair, skin and nails? Type I collagen is characterized by being extremely strong and able to stretch without breaking. Type III collagen is found alongside type I collagen in the skin and is important for the development of skin.

Besides being a key building block of your hair, skin and nails, the collagen in your body plays other vital roles. It also serves as one of the primary building blocks of bones, connective tissue, fibrous cartilage, ligaments, organs, skin, teeth, tendons—and even the gastrointestinal system.[2] Collagen benefits also include protecting your joints and maintaining the health of arteries, organs, and muscles.[2]

Even though collagen is one of the most plentiful proteins in the body, as you get older, your body makes less collagen, which can lead to loss of elasticity, dry skin, and wrinkles.[3,4]

Your body produces collagen, but you can also consume food sources of collagen. As a quick rule, think of foods with high protein content, such as chicken, pork, beef, or fish: collagen is primarily in their bones and skin. However, if you avoid those foods, you might consider a collagen supplement. But what's all the fuss about? What exactly does collagen do?

Let’s find out.

What Are The Benefits Of Taking Collagen?

If you've seen any ads for beauty supplements, or strolled down your local supermarket supplement aisle, you might already know that collagen is an ingredient in many supplements. But is collagen good for you?

Collagen, as a dietary supplement, is often paired with key nutrients that support healthy hair, skin, and nails, including:

  • Vitamin C, an antioxidant that helps neutralize free radicals in the body and plays an integral part in collagen synthesis
  • Biotin, may help support healthy hair, skin and nails for those low in biotin
  • Zinc, which helps support healthy skin

Be sure to read the supplement label to see what ingredients are in the supplement, and what benefits you can expect.

How Does Vitamin C Help with Collagen Production?

Vitamin C helps your body produce collagen—an essential process for supporting skin health. How? Fibroblasts are cells that produce collagen, and vitamin C interacts with key enzymes to support collagen synthesis and help these cells maintain collagen density in the skin.[5] Since Vitamin C is a key nutrient for anyone looking to support their body’s natural collagen production, it is often added to collagen supplements.

Does Taking Collagen Really Work?

Nature Made Collagen Peptides + C Gummies use Verisol®, which is a clinically studied ingredient. A double-blind study evaluated these collagen peptides, concluding that they helped reduce fine lines and wrinkles around the eye in as little as 4 weeks and supported healthy skin and elasticity in women.[1]

But when it comes to supplements, what should you look for? Most collagen supplements are made from animal sources like cartilage, skin and bones, and through a process called hydrolysis are broken into peptides or amino acids. Certain peptides from hydrolyzed collagen are absorbed in the body.[6]

You can find collagen in a variety of forms, including collagen gummies, powders, and pills. Nature Made offers two collagen gummy supplements, our Collagen Peptides + C Gummies and our Collagen Gummies, which include a daily source of collagen, along with skin health nutrients vitamin C and zinc in one delicious lemon-flavored gummy.

Are there any side effects to taking collagen? For instance, can collagen cause weight gain? Collagen supplements are considered safe with no known side effects—including weight gain.

What are the Benefits of Taking Collagen Peptides with Biotin?

Why does Nature Made's Collagen Peptides Drink Mix Powder include biotin? Biotin is an essential nutrient that supports healthy hair, skin, and nails. The clinically studied collagen peptides in this nondairy, soy-free, sugar free, and keto friendly drink mix powder support healthy joints and joint comfort.❖◾️️ Support an active lifestyle with clinically studied collagen and promote beauty from within with a daily source of biotin in one daily supplement.

What Age Does Collagen Stop Being Produced By the Body?

Once you hit your 20s, your collagen production begins to slow—roughly one percent every year.[3] Additionally, women can lose up to 30% of collagen production in the first five years of the onset of menopause.[7] Slowed collagen production can result in dry skin, loss of skin elasticity, and wrinkles. Nature Made Verisol® Collagen Peptides benefits for women include helping to reduce fine lines and wrinkles around the eye in as little as 4 weeks and supporting healthy skin and elasticity.

Besides age, environment and lifestyle also play a role in collagen production. Factors such as cigarette smoke, pollution, excess alcohol, sun exposure, and lack of sleep and exercise all contribute to the decrease in collagen production.[8] Here are some tips on how to support your body’s collagen production:

  • Avoid smoking and avoid being around secondhand smoke
  • Wear sunscreen when you spend time outdoors
  • Don’t overdo it when it comes to drinking alcohol: for women that's 1 drink per day (or less), and for men that's 2 per day (or less)
  • Get adequate sleep each night—seven to nine hours for most people

When Should You Start Taking Collagen? 

Collagen production naturally begins to decline in your 20s, and that’s when many people consider adding collagen to their diet or taking collagen supplements. Nature Made Collagen Peptides + C Gummies for healthy skin support include clinically studied collagen peptides to support healthy skin.

The Bottom Line

Collagen is an important protein that supports healthy skin, as well as playing an essential role in connective tissue and cartilage, among more collagen benefits. While our body produces collagen, our production slows with age, and supporting our body with a balanced diet and healthy habits can help us support our skin health at any age.

Taking a collagen supplement, like our Collagen Peptides + C Gummies, is a convenient, tasty way to get a daily dose of collagen to supplement your body's natural skin collagen production.
