Collagen is the most plentiful protein in the body. It has important roles, including providing structure to your skin and helping your blood clot. In recent years, collagen serum has gained popularity and collagen recognized as an important nutritional supplement and ingredient in shampoos and body lotions.

What is Collagen

Collagen is the most abundant protein in your body, accounting for about a third of its protein composition. It helps give structure to our hair, skin, nails, bones, ligaments and tendons in our body. Thanks to collagen, we’re better able to move, bend and stretch. Collagen is also behind helping hair shine, skin glow and nails stay strong.  It’s one of the major building blocks of bones, skin, muscles, tendons and ligaments. Collagen is also found in many other body parts, including blood vessels, corneas and teeth. You can think of it as the “glue” that holds all these things together. In fact, the word comes from the Greek word “kólla,” which means glue.

Types of Collagen

Collagen types contain different proteins which serve separate purposes within the body. Types 1 & 3 can be taken together and may support skin, muscles, bone health, and hair and nail growth and maintenance. Collagen Type 2 protein makes up the fluids and function in the cartilage and joints. Type 2 collagen supplements should be taken separately from Types 1 & 3 to ensure adequate absorption.

There are 19 amino acids (proteins) found in Collagen Types 1 & 3 – each essential to functions and maintenance within skin, muscles, and bones. These types are produced by fibroblasts (cells in connective tissues) and osteoblasts (cells that make bones).

Over 90 percent of collagen in the body is comprised of Type 1 & 3 Collagen. Proteins in these types include glycine, proline, alanine, and hydroxyproline.

  • Glycine: The amino acid found at the highest levels in collagen, requires more serine than our bodies can naturally produce. Studies suggest the need for glycine supplementation to achieve ideal metabolic processes
  • Proline: A non-essential amino acid synthesized from glycine and important in function of joints and tendons
  • Hydroxyproline: Amino acid that plays an essential role in the stability of collagen
  • Alanine: Amino acid used in the biosynthesis of proteins

Collagen Type 2 is produced by chondrocytes (the non-cellular matrix of cartilage) – a liquid-like filling within the cartilage.

Collagen Benefits

  1. Improves Health of Skin and Hair

As we age, collagen production declines. You’ll notice it physically: looser skin, more wrinkles and less elasticity. Increasing collagen levels can help your skin look firmer, increase smoothness, and help your skin cells keep renewing and repairing normally.

Double-blind, placebo-controlled studies investigating the anti-aging properties of collagen have found that 2.5–5 grams of collagen hydrolysate used among women aged 35–55 once daily for eight weeks significantly improved skin elasticity, skin moisture, transepidermal water loss (dryness) and skin roughness, all with little to no side effects. This makes collagen one of the best natural skin care ingredients available.

Collagen also reduces cellulite and stretch marks. When skin loses its elasticity as a result of decreased collagen, there’s another side effect: more visible cellulite. Because your skin is now thinner, cellulite becomes more evident — no more hiding what’s happening below the surface. Improving your skin’s elasticity through collagen helps reduce that dimpling on your skin.

  1. Reduces Joint Pains and Degeneration

With its gel-like, smooth structure that covers and holds our bones together, collagen allows us to glide and move without pain. Think of ingesting more collagen like greasing a creaky door hinge: It helps your joints move more easily, reduces pain often associated with aging and even reduces the risk of joint deterioration. It’s no surprise then that a recent study even found that collagen is an effective treatment for treating osteoarthritis and other joint pain and disorders.

  1. Helps Heal Leaky Gut

If you suffer from leaky gut syndrome, a condition where bad-for-you toxins are able to pass through your digestive tract, collagen can be super-helpful. It helps break down proteins and soothes your gut’s lining, healing damaged cell walls and infusing it with healing amino acids.

The biggest digestive benefit of consuming more collagen is that it helps form connective tissue and therefore “seals and heals” the protective lining of the gastrointestinal tract. Today, we know that many illnesses can actually be traced back to inflammation or irritation stemming from an unhealthy gut. Poor gut health — including changes in the gut microbiome and permeability in the gut lining — allows particles to pass into the bloodstream where they can kick off an inflammatory cascade (hence the name leaky gut syndrome).

Studies have found that in patients with inflammatory bowel disease, serum concentrations of collagen are decreased. Because the amino acids in collagen build the tissue that lines the colon and GI tract, supplementing with collagen can help treat gastrointestinal symptoms and disorders, including leaky gut syndrome, IBS, acid reflux, Crohn’s disease and ulcerative colitis. In addition to helping heal leaky gut, collagen also helps with the absorption of water within the intestines, keeping things moving more freely out of body.

  1. Boosts Metabolism, Muscle Mass and Energy Output

A boost in collagen may help increase your metabolism by adding lean muscle mass to your frame and helping with the conversion of essential nutrients. One of glycine’s most important roles is helping form muscle tissue by converting glucose into energy that feeds muscle cells. And remember that retaining muscle mass is crucial as you age, since it helps support posture, bone health and burns more calories than fat. When consuming collagen, you can benefit from also consuming vitamin C to ensure your body can convert the collagen into a useable protein. This can begin to restore the source or your energy and vitality.

That’s not all that glycine can do for your metabolism. Research shows glycine also has important roles in both functions of the digestive and central nervous systems, which play big roles in maintaining a healthy, youthful body. Glycine seems to help slow the effects of aging by improving the body’s use of antioxidants and is also used in the process of constructing healthy cells from DNA and RNA.

In addition, it’s been found that arginine boosts the body’s ability to make protein from other amino acids, which is important for repairing muscle tissue, healing wounds, sparing tissue wasting, boosting the metabolism, and aiding in proper growth and development. And glutamine also helps maintain adequate energy by facilitating the synthesizing of many chemicals. This amino acid provides “fuel” to our cells, including carbon and nitrogen.

  1. Strengthens Nails, Hair and Teeth

Collagen protein is the building block of your fingernails, hair and teeth. Adding collagen into your diet regimen can help keep your nails strong and possibly reverse signs of hair loss.

  1. Improves Liver Health

If you’re looking to detox your body of harmful substances, improve blood flow and keep your heart young, collagen is extremely helpful. That’s because glycine helps minimize damage your liver experiences when it absorbs foreign substances, toxins or alcohol that shouldn’t be passing through it.

One of the easiest ways to cleanse your liver is with a bone broth fast. This may help your body rid itself of chemicals and “reset” your gut, improving overall immune function. Studies have even found that glycine can be used to help reduce alcohol-induced liver damage and other forms of acute or chronic liver injury.

  1. Protects Cardiovascular Health

The amino acid proline helps your artery walls release fat buildup in the bloodstream, shrinking the fat in the arteries and minimizing fat accumulation. Proline is needed for tissue repair within the joints and arteries, plus it helps control blood pressure. As part of collagen found within joints, it buffers our bodies from the effects of vibration or shock and helps us hold on to valuable cartilage as we get older.  It’s also linked with the prevention of arteriosclerosis (hardening of the arteries) since it helps our arteries stay clear of dangerous plaque buildup.

Top Ways to Consume More Collagen

  1. Making and drinking real bone broth.
  2. Using bone broth protein in recipes. You can consume bone broth on its own or use it in all sorts of sweet and savory recipes depending on the type of product.
  3. Taking collagen supplements.
  4. And lastly, eating a well-rounded diet that helps increase absorption of the collagen you consume.
