Gelatin vs Collagen: What Is the Difference?

Gelatin and collagen are both nutritious substances that are praised for their wonderful benefits for joint, bone, skin, and gut health. Like many people, you may be unsure what is the difference between the two and if one is better than the other.

Collagen is the most abundant protein found in your body. It’s the primary substance of connectives tissues that provides structural support holding your body together and is essential for the health of your skin, gut, joints, ligaments, bones hair, nails, teeth, heart, and liver.

However, as you age, your body’s natural collagen production slows down and requires outside help. Fortunately, through diet and lifestyle, you can improve your collagen levels and boost your health.  This is where collagen peptides and gelatin comes into the picture.

Collagen and Gelatin

Collagen peptides and gelatin are both important proteins rich in amino acids derived from the collagen protein molecule found in animal connective tissues. While both are beneficial for your health, they require a different method of preparation, have a different texture, and have different culinary and nutritional applications.

In this article, you will learn what collagen and gelatin are, their benefits, and the difference between the two. You will learn some natural ways to boost collagen production, my favorite collagen-filled and gelatin-rich recipes, and collagen-boosting supplements I recommend.

gelatin, Gelatin vs Collagen:  What is the Difference?What Is Collagen?

Collagen is a structural protein that is also the most abundant protein in most animals. Collagen is the main component of connective fibers in tissues, such as your skin, cartilage, ligaments, bones, and teeth. It makes up about a quarter of your entire body’s protein content and about 70 percent protein content of your skin (1).

It is a structural protein that is found in your skin, hair, blood vessels, cartilage, ligaments, bones, intervertebral discs, teeth, and digestive tract. It gives bulk, shape, and support to your blood vessels, bones, and organs, such as your liver, kidneys, and heart.

Collagen practically serves as an intracellular ‘glue’ that holds your body together. It provides cushioning for your joints and tendons to stay healthy and active. It allows your body to move better, stretch, and bend. It supports your skins elasticity, strength, and integrity, hence the lack of collagen is responsible for visible signs of aging, such as wrinkles.

gelatin, Gelatin vs Collagen:  What is the Difference?What Is Collagen Made Of?

Collagen is a complex protein that is made up of 18 different amino-acids that serves as building blocks for your body.

The most abundant amino acids in collagen include:

  • Proline: Proline makes up about 15 percent of collagen. It protects your blood vessels, supports cardiovascular health, and provides joint cushioning.
  • Glutamine: Glutamine helps to reduce anxiety, brain fog, insomnia, low energy, compromised immunity, and weakened digestive function.
  • Glycine: Glycin takes up about a third of all collagen. It helps the production of DNA strands, creatine formation, muscle growth, and energy regeneration.
  • Arginine: Arginine helps to create nitric oxide in your body, which is important for your immune system and cardiovascular function.

Other amino acids found in collagen include Alanine, Hydroxyproline, Glutamic acid, Aspartic acid, Serine, Lysine, Leucine, Valine, Threonine, Phenylalanine, Isoleucine, Hydroxylysine, Methionine, Histidine, Tyrosine, Cysteine.

Symptoms of Poor Collagen Production

Collagen is incredibly important for your body’s healthy functioning and overall health. Poor collagen production may lead to a variety of health issues, including:

    • Joint pain
    • Skin blemishes
    • Weakened nails
    • Osteomalacia
    • Increased frequency of injuries
    • Osteoarthritis
    • Repetitive injuries
    • Tight Muscles and Joints
    • Wrinkles
    • Osteoporosis
    • Hair thinning

Collagen offers many benefits for your health, including a healthy metabolism, better digestion, healthier skin, and stronger hair. Let’s look at each benefit one by one.

Supports a Healthy Metabolism

Glycine, one of the amino acids in collagen helps to form muscle tissue by converting glucose into energy to feed your muscle cells. Two other amino acids in collagen, arginine, and glutamine help to boost your body’s ability to make protein and fuel your cells to maintain energy. As a result, collagen supports healthy metabolism and may help your weight loss efforts (2, 3).

Helps Repair and Heal Leaky Gut

Leaky gut, or intestinal hyperpermeability, is a condition in which tight junctions in your gut lining become too large and allow undigested food particles and toxins into your bloodstream leading to chronic inflammation, gut problems, and health issues. Glycine and glutamine in collagen help to repair damaged cells, rebuilding new tissue, and improve gut health problems.

Strengthen Bones, Teeth, and Nails

About one-third of your bones are made up of collagen. Healthy collagen levels are essential for strong bones, strong jaw, healthy teeth, and healthy gum tissues. It also supports nail growth and healthy nails (4, 5).

Improves Skin and Hair Quality

The protein of your skin is about 70 percent collagen. Collagen is an essential building block of your skin. It’s important for skin elasticity and moisture. Collagen is essential for reducing wrinkles and maintaining a youthful skin tone. It is also important for healthy and strong hair, and for preventing hair loss (6).

Reduces Cellulite and Stretch Marks

Collagen is essential for your skin’s elasticity, thinnest, and appearance. Hence it may help reducing cellulite and stretch marks (7)

Protects the Heart

Collagen provides a structural framework for cardiac muscle cells. It provides the necessary stiffness to your heart wall, keeps your blood vessels strong, and helps repair tissue in the arteries (8, 9)

Supports the Liver and Detoxification

Your liver is your largest organ inside your body and is essential for detoxification. Glycine in collagen may help to reduce the damage to the liver from toxins, improve detoxification, and better your body’s use of antioxidants (10).

Repairs and Strengthens Joints, Tendons, and Ligaments

Collagen is a gel-like, smooth substance that covers and holds your joints together. It makes up the connective tissues such as tendons and ligaments that hold your muscles and bones together. It serves as a cushion and ‘shock absorber’. Optimal collagen levels help bone, joint, tendon, ligament, and muscle health, and may reduce the risk and symptoms of osteoarthritis, rheumatoid and other arthritis pain, and joint pain in athletes (11, 12).

Improves Sleep Quality

Glycine is collagen may be a therapeutic option for improving your sleep quality. It is important for regulating cortisol levels and promoting healthy relaxations during sleep (13).

You might’ve heard that gelatin is great for your joints. It’s because when collagen breaks down, it turns into gelatin.

The truth is that though raw animal skin or hooves are good sources of collagen, they are not exactly human food. Unlike other animals, humans cook, boil, roast, or bake their food. Cooking turns collagen into gelatin.

Through this long and slow heating action, collagen proteins change through a process called denaturing. They become liquid, and once cooled, they become a wiggly and jiggly somewhat solid substance like Jell-O. This process not only gives you soups and stews a nice flavor and texture, but also provide your body amino acids that needed for collagen production and improve your gut health, skin, hair, nails, and overall health as a result (14).

Benefits of Gelatin

Gelatin has a number of health benefits you should be aware of. Since gelatin contains the same amino acids as collagen does, they have similar health benefits.

Health benefits of gelatin include (15, 16):

      • Improving skin health
      • Strengthening bones and joints
      • Improving hair quality
      • Providing plenty of healthy protein
      • Boosting digestive function
      • Helping weight loss
      • Improving sleep

Collagen vs Gelatin

Collagen peptides and gelatine both have their place in your diet depending on your needs. While gelatin is great, it may also be tricky to make. Gelatin needs hot water to dissolve completely. If the water is not hot, but lukewarm or cold, you end up with a clumpy substance forming a gelatinous blob.

Collagen peptides, on the other hand, are smaller collagen protein fractures. They are collagen particles that have been completely broken down. They dissolve easily and may be mixed with water, smoothies, shakes, coffee, and other recipes. 

Collagen peptides possess all the important amino acids that gelatin does for proper collagen function and overall health. They may promote healthy, youthful skin, gut health, strong hair and skin, joint health, and overall health. They are also incredibly convenient and simple to use.

gelatin, Gelatin vs Collagen:  What is the Difference?How to Boost Collagen Production

The truth is that collagen production naturally decreases as we age. However, it may also decrease or become depleted as a result of poor lifestyle choices, such as sleep deprivation, excess sugar, refined carbs, low vitamin C, high cortisol levels, smoking, and exposure to UV rays. 

It is not enough to rely on your body to produce collagen to achieve optimal levels. You have to help it through good lifestyle choice, a nutrient-dense diet, and proper supplementation.

Some tips you may try to support your body’s healthy collagen production and your overall health include:

      • Get your recommended daily serving of vitamin C through vitamin C rich foods, such as citrus, kiwis, and kale, and supplementation.
      • Eat foods that are rich in Proline such as asparagus, cabbage, free-range eggs, mushrooms, watercress, and tempeh.
      • Eat foods rich in Glycine, such as bananas, cauliflower, kale, spinach, cucumber, and beans.
      • Drink bone broth regularly. It is a highly nutritious drink with lots of collagen.
      • Eat clean protein such as grass-fed beef, free-range poultry, and organ meats.
      • Try my favorite healing recipes with collagen and gelatin.
      • Try natural supplementation, such Collagen Peptides, and Beef Gelatin by Vital Proteins
      • Sleep plenty. Aim for 7 to 9 hours of restful sleep a night.
      • Drink lots of water. Aim for 8 to 10 glasses a day, more if you are working, spending time outdoors on the hot sun, using the sauna, or recovering from an illness.

Healing Recipes with Gelatin

Health doesn’t have to taste boring. In fact, nutritious recipes can taste amazing. There are so many nutrient-dense, guilt-free healing recipes out there that both adults and children will love. Just ask my sons, David and Joshua, who absolutely love their Gut Healing Gummy Bears and collagen-boosting Chocolate Cream Pie

You can too enhance your body’s health by eating healing recipes with gelatin. Try some of my favorites we eat regularly with my family and I recommend to my patients all the time:


The Best Collagen and Gelatin

Making bone broths is one of the easiest ways to add nutritious collagen to your body. While you can certainly make your own bone broth from organic bones of animals, including pork, beef, veal, turkey, lamb, bison, chicken, or fish, for convenience, you may also try some bone broth powders. Bone broth powders are great because they are so versatile and you may use them in your shakes, smoothies, and other recipes. 

Final Thoughts on Gelatin and Collagen

Collagen is the primary substance of connective tissues and the most abundant protein in your body. It provides structural support and is necessary for the health of your skin, gut, joints, ligaments, bones hair, nails, teeth, heart, and liver. 

As you age, your body’s natural collagen production decreases. Fortunately, through a healthy diet and lifestyle, you can improve your collagen levels. Collagen peptides and gelatine may both help collagen levels in your body.
