What Are Collagen Peptides?

Collagen is the most abundant protein found in the human body. It is essential for building muscle, skin, and connective tissues like tendons and ligaments. However, the body can't absorb it whole. Breaking it down into amino acids called peptides increases its bioavailability and allows the body to absorb it better.

The body uses collagen peptides for numerous functions, such as maintaining skin health, supporting joints, and repairing muscle tissues. They promote skin elasticity, reduce wrinkles, and improve overall skin appearance. They support joint function, reduce joint pain, and enhance joint flexibility by maintaining collagen levels in the cartilage that cushions joints. Collagen peptides also help repair ligaments, tendons, and muscle tissues to ensure optimal joint mobility and physical well-being.

What is Hydrolyzed Collagen?


Collagen comes from the Greek word kola, meaning glue producer. Ancient cultures boiled the skin and sinewy tissues of animals, notably horses. In fact, the oldest glue in the world was made with collagen over 8000 years ago. It still has a role in gluemaking, but modern research identified several other beneficial collagen properties.

Collagen is a fibrous protein found in connective tissues, such as the skin, organs, tendons, ligaments, cartilage, and bones. It’s made up of the amino acids glycine, proline, and hydroxyproline, which form into three tropocollagen strands. These strands break apart when subject to denaturation (e.g., applying sufficient heat). However, too much heat can cause collagen proteins to lose their structure and ability to function.

Denatured collagen produces gelatin, whereas hydrolyzed collagen is the product of hydrolysis. Hydrolysis uses water to break down collagen proteins into peptides, which have numerous applications in the dermatology/skin care, pharmaceutical, cosmetics, and food industries. Gelatin and hydrolyzed collagen share many properties, but the primary reason they aren’t used interchangeably is that gelatin hardens into a gel-like substance once cooled. The hydrolyzed form is easier to absorb and less likely to lose efficacy from heat damage. Collagen peptides also dissolve in hot or cold water, whereas gelatin is only soluble in hot water.

Hydrolysis doesn’t affect the amino acid content of collagen. Hydrolyzed collagen peptides contain 19 amino acids, including 8 out of 9 essential amino acids (lacking tryptophan). Its concentration of glycine and proline amino acids is particularly notable, as they are 10 to 20 times higher than in other proteins.

Why Do We Need Hydrolyzed Collagen?

Many people have insufficient levels of the amino acids needed to make collagen due to poor food choices. Hydrolyzed collagen provides a bioavailable form of collagen that is easy for the body to process. Up to 30 percent of all the protein in the human body is collagen, including up to 70 percent of the proteins in connective tissues. Collagen peptides support several areas of health, including maintaining youthful-looking skin, joint function, muscle growth, and more.

What is Bovine Collagen?

Collagen exists in 20 forms within the body, but the most prevalent are types I, II, III, and IV. Collagen supplements often come from animal sources, such as cows, pigs, and some aquatic animals. Bovine collagen peptides boost types I and III, whereas fish collagen increases types I and II. Types I and III are most prevalent in skin cells, making bovine collagen peptides particularly effective for improving skin elasticity, moisture, and smoothness. PureBulk’s hydrolyzed collagen is from 100% grass-fed cows. Bovine collagen is a good choice for individuals with food sensitivities or allergies to fish, shellfish, or eggs.

Potential Collagen Powder Benefits

Collagen Benefits for Skin

Collagen plays a critical role in skin elasticity, strength, and hydration. The body's natural ability to produce collagen and maintain hydration of the cells diminishes significantly after age 25. Too much time in the sun can reduce collagen production as well. Taking hydrolyzed collagen peptides may help revert some of the signs of aging due to collagen loss. Hydrolyzed collagen peptides also promote hyaluronic acid synthesis, another compound that improves the appearance of skin. Numerous studies have reviewed collagen’s effects on the skin, concluding that hydrolyzed collagen improves skin hydration and elasticity while reducing the appearance of wrinkles better than placebos.

Collagen for Muscle Growth

Collagen comprises up to 10% of human muscle, and taking collagen supplements may support healthy muscle tissue and growth. Collagen can also increase creatine, a protein that delivers energy to muscles during workouts. Collagen also promotes healthy joint function, which is critical for flexibility and mobility during exercise. Although collagen is a protein, it should not replace protein found in foods such as fish, beef, poultry, and whey protein. It is not a complete protein, as it has insufficient amounts of cysteine and methionine.

Collagen For Weight Loss

Collagen may facilitate weight loss and help individuals maintain their weight. Eating more protein is a great way to improve satiety, as it takes the body longer to digest it. Collagen can also boost satiety hormones, helping individuals feel full and satisfied for longer.

Collagen for Joints

Cartilage and tendons can begin to loosen with insufficient collagen, making joints more prone to injury. Dozens of scientific studies show hydrolyzed collagen supplements help support healthy joints by reducing collagen damage, joint pain, stiffness, and loss of bone density. Supplemental collagen may build up in cartilage tissue over time, stimulating natural collagen production. The abundance of collagen helps support cartilage health and reduce inflammation. Hydrolyzed collagen is a popular option for long-term use to support joint health due to its high safety profile.

Types of Collagens

Researchers have discovered 28 types of collagens. However, the most commonly occurring are types I – IV, with type I accounting for 90% of all the collagen in the human body.

  • Collagen type I: Type I is the most abundant collagen in humans. It’s found in skin, hair, nails, bones, ligaments, and tendons.
  • Collagen type II: Type II collagen provides joint support and is found in elastic cartilage. It may be easier for the body to absorb type II than type I, as it isn’t as densely packed.
  • Collagen type III: Type III is the second most common collagen that occurs naturally in humans. It plays a role in blood clotting and wound healing. It’s found in muscles, organs, arteries, and blood vessels.
  • Collagen type IV: Type IV collagen is found in the skin that helps form the basement membrane zone (BMZ). The BMZ protects tissues from mechanical stress, such as bending, compression, shear, tension, and torsion.

Food with Collagen

Most collagen supplements come from bovine, chicken, or fish sources. However, numerous foods contain collagen. These include:

  • Fish with skin
  • Shellfish, particularly oysters
  • Bone broth
  • Meats, such as beef and chicken
  • Eggs

All collagen-rich foods come from animal sources. However, spirulina is rich in the amino acids the body needs to synthesize collagen, and it’s vegan- and vegetarian-friendly.

What is the Best Collagen Supplement?

PureBulk carries several forms of collagen supplements. The best collagen supplement depends on the individual’s needs.

  • Marine collagen is a type I collagen. It helps repair muscle tissue, support cartilage health, and promote wound healing.
  • Chicken collagen is a type II collagen and is a good supplement to support joint health.
  • Bovine collagen provides type I and type III collagen. It helps strengthen bones and tendons. It also improves skin elasticity and reduces the appearance of wrinkles.

Potential Collagen Powder Side Effects

No side effects or toxicity from collagen hydrolyzed or adverse interactions with food or medications have been reported by the FDA. Some individuals may experience heartburn or a feeling of fullness. External use of hydrolyzed collagen is generally considered safe. Those with sensitive skin may experience a condition known as contact dermatitis. If itching, swelling, or a rash develops, immediately discontinue the use of the product.
