What is Hydrolysed Collagen?

What is Hydrolysed Collagen? Bulk Nutrients' HCP - Hydrolysed Collagen Peptide

Collagen is the body's most abundant protein. In fact, it accounts for 30% of the body’s natural protein content.

We rely on collagen to provide structure, strength and support to our skin, bones, muscles and other connective tissues, as well as our organs, blood vessels and intestinal lining.

However, collagen production naturally declines as we age, which is why our skin wrinkles and our bones and muscles weaken.

That’s where collagen supplements come in.

Collagen supplements help to increase the body’s natural collagen stores and prompt our bodies to produce more collagen themselves.

Typically, collagen supplements are made of hydrolysed collagen, as this form of the essential protein is better absorbed and used by the body.

What is Hydrolysed Collagen?

So, what is hydrolysed collagen?

Hydrolysed collagen, also known as collagen hydrolysate or hydrolysed collagen peptides, is formed when whole collagen proteins are broken down into smaller, easily-absorbed particles through a process called hydrolysis.

Hydrolysed collagen is made up of a unique combination of amino acids, which are the building blocks of protein.

It contains 19 amino acids, including very high levels of proline, glycine and hydroxyproline.

Different Forms of Hydrolysed Collagen

Hydrolysed collagen is used in topical products (like skincare) and ingestible products (like supplement capsules).

Collagen is a popular skincare ingredient thanks to its anti-ageing properties. You’ll typically find hydrolysed collagen in products designed to reduce fine lines or wrinkles - think night creams, serums and moisturisers.

However, ingesting collagen is the most effective way to increase your body’s collagen stores.

Hydrolysed collagen can be found in various ingestible forms including tablets, powders or capsules. It also comes infused in drinks, such as tea, water and even coffee.

We’ve formulated our delicious Hydrolysed Collagen Peptide Powders in a variety of exciting flavours, perfect for adding to your favourite smoothie.

Whether you prefer a tropical twist or you’re in the mood for something indulgent (check out our Rich Chocolate flavour), we have something to suit your taste buds.

Hydrolysed Collagen Benefits

When taken daily and at the recommended dose, hydrolysed collagen offers a wide range of benefits.

At a glance, hydrolysed collagen can help...

  • ...reduce signs of ageing, studies have found that hydrolysed collagen can help reduce signs of skin ageing, including wrinkles .
  • ...improve your skin, ingesting hydrolysed collagen improves skin texture, firmness, hydration and elasticity.
  • ...assist with mineral deficiencies, given collagen hydrolysates can attach to calcium ions and therefore be more easily absorbed by your body, they can be added to food to help manage mineral deficiency.
  • ...aid weight loss efforts, bovine collagen, or collagen from cows, can help you with your weight loss efforts.
  • ...reduce painful symptoms of osteoarthritis, a study found that regular intake of pharmaceutical-grade collagen can reduce the pain of osteoarthritis, particularly in the knee or hip.
  • ...improve muscle growth, collagen is a protein, and proteins can help you grow your muscles. A study on collagen peptides found that supplementing your diet with collagen can help to increase your body composition by promoting lean muscle-mass growth.

Hydrolysed Collagen Side Effects

Hydrolysed collagen is widely tolerated and when consumed properly should not cause any unpleasant side effects.

However, if you’re allergic to certain animal byproducts or you ingest too much collagen, you may experience side effects such as allergic reactions as hydrolysed collagen powder typically comes from cows or marine animals. If you have related allergies, you may experience an allergic reaction.

HCP Protein Powder is great to use in baked goods and cooking
