Product Details

What is Hydrolyzed Collagen Powder (Fish)?

Collagen is a type of structural protein found in the skin, bones, joints, muscles, ligaments, and tendons. It is the most abundant protein found in mammals and accounts for 25-35% of the protein in the human body. Collagen contains 19 amino acids, including eight of the nine essential amino acids. While it lacks the essential amino acid tryptophan, it includes the amino acid hydroxyproline. Hydroxyproline does not occur in any other type of protein and makes up one-third of tropocollagen strands. In addition to hydroxyproline, tropocollagen triple helixes include the amino acids glycine and proline.

Applying heat breaks the strands apart in a process known as denaturation and produces gelatin. However, too much heat can destroy collagen protein’s structure and capacity to function. Hydrolysis uses water to break collagen down into tiny pieces of protein known as collagen peptides. Hydrolysis is less likely to damage the collagen peptides than denaturation as it doesn’t require high heat.

Peptides from fish collagen, also known as marine collagen, come from hydrolyzing the skin and bones of fish. Using these parts to make marine collagen powder is environmentally friendly, as most food processing plants would otherwise discard them.

What Are Collagen Peptides?

Collagen peptides are short chains of amino acids that come from collagen, an abundant protein in the body that is essential for skin, hair, nails, joints, and other connective tissues. Breaking collagen down into smaller peptides makes them easier to absorb.

Collagen peptide supplements support skin elasticity, joint health, and overall collagen production. Consuming collagen peptides may help improve skin hydration, reduce wrinkles and fine lines, promote joint health by supporting cartilage and reducing joint pain, strengthen hair and nails, and even support gut health by improving the intestinal barrier function.

Why Do We Need Hydrolyzed Collagen?

Collagen is necessary for the proper functioning of connective tissues. However, many individuals fail to consume the amino acids they need from their diets to synthesize enough collagen. The body also becomes less able to synthesize collagen naturally after the age of 25. Hydrolyzed collagen can fill this gap, as the body absorbs and processes it readily.

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 Marine Collagen Benefits

Marine Collagen for Weight Loss

Collagen may support weight loss efforts due to its protein content. Protein is a longer-lasting energy source compared to carbohydrates because the body digests it slower. Collagen may help individuals feel fuller for longer due to its interactions with satiety hormones. The body also burns more calories while digesting protein than it does with carbohydrates.

Looking for Complete Proteins?

Whey protein powder is a complete protein. Chlorella is a good vegan-and vegetarian-friendly complete protein.

Marine Collagen Protein for Muscle Growth

Collagen may support muscle growth by boosting creatine levels. Creatine promotes muscle growth by rapidly resynthesizing adenosine triphosphate (ATP). The body uses ATP for energy during high-intensity exercise. Hydrolyzed collagen supplements also support joint health by reducing the likelihood of injuries while improving flexibility and mobility. However, hydrolyzed collagen supplements are not complete proteins, as their cysteine and methionine levels are too low.

Marine Collagen for Joint Health

Cartilage and joint stability rely on sufficient collagen levels. Collagen supplements help stimulate natural collagen production, which helps build cartilage tissue and reduce inflammation. Research shows collagen also supports joint health by reducing joint stiffness, pain, and loss of bone density. Numerous studies support hydrolyzed collagen’s high safety rating for long-term joint health support.

Potential Marine Collagen Benefits for Skin

The skin requires ample collagen to retain its elasticity, durability, and hydration. Skin may begin to sag and develop with age as natural collagen production declines. Hydrolyzed collagen supplements may help attenuate the loss of collagen to provide healthy, more youthful-looking skin. Collagen also boosts hyaluronic acid production, which also improves the appearance of skin and skin hydration. Scientific research supports collagen’s skin-enhancing properties, as the studies show collagen improves skin hydration, elasticity, and the appearance of wrinkles.

Marine Collagen for Hair Growth

Collagen may benefit the appearance of hair in several ways. Hair primarily consists of keratin proteins, and collagen is rich in the amino acids used to create keratin. Marine collagen is particularly effective for protecting hair follicles against free radical damage. Collagen may also help reduce hair thinning by improving skin strength and elasticity.

Potential Marine Collagen Side Effects

Hydrolyzed collagen has a good safety profile with no adverse effects reported to the FDA. However, individuals with shellfish allergies or sensitivities should not take hydrolyzed collagen sourced from fish. PureBulk also carries bovine collagen and chicken collagen. Some individuals may experience feelings of fullness or heartburn while taking hydrolyzed collagen supplements.

Collagen Side Effects on Kidney Stones

Most individuals can consume collagen supplements without kidney concerns. However, individuals prone to developing kidney stones should not take collagen supplements. Collagen contains the amino acid hydroxyproline, which converts into oxalate. For most individuals, this is not a problem. However, oxalates can contribute to the formation of kidney stones in individuals prone to developing them.
