What Are Collagen Supplements?

Collagen is the most abundant protein in the human body and is found in skin, bones, tendons, ligaments and cartilage. Collagen supplements provide collagen in an easy-to-take form, usually as hydrolysed collagen peptides that dissolve in drinks. You'll find them as collagen powder, capsules, tablets, liquid shots and ready-made drinks like collagen coffee.

At Nutrition Warehouse, we stock over 70 collagen supplements from trusted Australian and international brands, so you can buy collagen online or in-store in the format that suits your routine.

Shop Collagen by Type

Not sure where to start? Our collagen range is split into a few key categories:

Types of Collagen

There are many types of collagen in the body, but most collagen supplements contain one or more of these three:

• Type I collagen: the most common type in the body, found in skin, bones, tendons and ligaments. Marine and bovine collagen are both rich in type I.
• Type II collagen: mainly found in cartilage. It's often included in multi-source collagen blends.
• Type III collagen: found alongside type I in skin, muscles and blood vessels. Bovine collagen contains types I and III.

Collagen is made up of amino acids, mainly glycine, proline and hydroxyproline.

Where Does Collagen Come From?

• Bovine collagen: sourced from cows, often grass-fed, and contains types I and III.
• Marine collagen: sourced from fish skin and scales, and is mainly type I.
• Multi-source collagen: blends collagen from several sources, such as bovine, chicken, fish and eggshell membrane.
• Vegan collagen boosters: collagen only comes from animals, so vegan options contain ingredients such as vitamin C instead of collagen.

Collagen Powder, Capsules or Drinks?

• Collagen powder: the most popular format. Powders usually give the largest serve of collagen and mix into water, coffee, smoothies or baking.
• Collagen capsules and tablets: no mixing needed, so they're easy to take on the go.
• Liquid collagen and shots: ready to drink straight from the pack.
• Collagen coffee and creamers: collagen combined with coffee or added to your daily cup.
• Collagen snacks: collagen jellies, mousses and protein bars made with collagen.

How to Choose a Collagen Supplement

1. Your goal: choose a skin, hair and nails formula, a joint and recovery formula, or pure collagen peptides for everyday use.
2. Collagen source: choose marine, bovine or multi-source collagen based on your diet and preferences.
3. Format: powders suit coffee and smoothies, while capsules, tablets and shots need no mixing.
4. Added ingredients: compare pure collagen with blends that add vitamin C, biotin, zinc or hyaluronic acid.
5. Collagen per serve and cost per serve: check the label for how much collagen is in each serve, and compare tub sizes for value.

How to Take Collagen

Read the label and follow the directions for use. Most collagen powders are taken as one serve a day, mixed into water, coffee, tea or a smoothie. Unflavoured hydrolysed collagen dissolves in hot and cold drinks, so many people add it to their morning coffee. Capsules, tablets and liquid shots are taken as directed on the label.

What to Pair with Collagen

• Vitamin C: vitamin C is involved in the body's own collagen formation, which is why many collagen blends include it. If your collagen doesn't contain vitamin C, you can pair it with a vitamin C supplement. If it already does, check the label so you don't double up.
• Protein powder: collagen isn't a complete protein, as it doesn't contain the essential amino acid tryptophan. If you're using protein to reach your daily target, take collagen alongside your usual protein powder rather than instead of it.
