Collagen
What is Collagen?
Collagen is the most abundant protein in the human body, acting as a structural protein in connective tissue that provides structure to skin, cartilage, tendons, ligaments, and bone, and it also makes up the bulk of the organic matrix in bones. Types I and III collagen are the most abundant, with marine collagen primarily rich in type I collagen and bovine collagen typically containing types I and III. As we age, natural collagen production declines, and because vitamin C is required for collagen synthesis, many people use collagen supplements to support skin elasticity, joint comfort, training recovery, and overall healthy ageing, while hydrolysed collagen peptides may help support natural collagen production; daily collagen supplementation may also improve skin hydration and skin's firmness, and some studies report a small reduction in wrinkle depth.
How Much Collagen Should You Take?
For how much collagen to take, 10 to 20 grams daily is a common guide, many effective products provide 5 to 15 grams per day, and one serving often contains 10 to 15 grams per serving. Results usually depend on collagen supplementation taken daily for at least 8 weeks, with most studies showing benefits after consistent use over several months.
Our Premium Collagen Range
At Sportsfuel, we stock a premium selection of the best collagen supplements in NZ, including collagen powder, collagen peptides, marine collagen, and convenient capsule options from trusted local and international brands for skin, hair and nails, healthy joints, and broader skin support as part of a beauty supplement routine. Hydrolysed collagen peptides are broken down into smaller peptides and amino acids, which makes high quality collagen easier to digest and absorb than natural collagen while fitting alongside your overall protein intake, so it can complement total protein intake and add protein per serving. Collagen supplements are generally well tolerated, although some people may notice mild digestive discomfort. Collagen powder also mixes easily, works especially well in warm liquids, can be added to cold drinks, and pairs well with vitamin C-rich foods for absorption support.

Frequently Asked Questions
-
Collagen is the most abundant protein in the human body and the main structural protein that forms connective tissue. It provides structure to skin, hair, nails, joints, cartilage, tendons, ligaments, bones, and blood vessels. As we age, natural collagen production declines, which is why many people use collagen supplements to support skin elasticity, joint health, and overall structural support.
-
Common signs of low collagen levels include wrinkles and sagging skin, joint stiffness or discomfort, weaker hair and nails, reduced skin elasticity, slower recovery from exercise, and general aches in connective tissues. Collagen production naturally decreases with age, but lifestyle factors such as excess sun exposure, smoking, and high sugar intake can accelerate collagen breakdown.
-
Collagen supplements are broken down into amino acids and peptides, which the body uses to produce collagen and other structural proteins like elastin. Research suggests collagen supplementation may help support skin hydration and elasticity, joint comfort, and connective tissue health when taken consistently. Results vary, but many people notice improvements after several weeks of daily use.
-
Marine collagen is sourced from fish and is typically rich in Type I collagen, which is important for skin, hair, and nails.
Bovine collagen is sourced from cattle and commonly contains Types I and III collagen, supporting skin, joints, and connective tissue.
Both forms are effective, and most collagen powder in NZ is available in hydrolysed (collagen peptides) form for easier digestion and absorption. -
Although there are over 30 types of collagen, the most common include:
Type I: Supports skin, bones, tendons, and connective tissue
Type II: Found in cartilage and supports joint health
Type III: Supports muscles, organs, and blood vessels
Type V and X: Involved in tissue structure and cartilage formation
Most collagen supplements focus on Types I and III for skin support or Type II for joint support. -
The best collagen supplement in NZ depends on your goals. Collagen powder is the most popular option because it’s versatile and easy to mix into coffee, smoothies, or protein shakes. Capsules offer convenience, while specialised formulas may include added vitamin C or other nutrients to support collagen production. Choosing a high-quality, hydrolysed collagen supplement ensures better absorption and ease of use.
-
Most people take collagen powder daily and may begin noticing improvements in skin hydration or joint comfort within 4 to 8 weeks. Consistency is key, as collagen supplementation works gradually by supporting your body’s natural collagen production processes.
-
Collagen supplements are generally considered safe for daily use for most people. Side effects are rare and usually mild, such as feelings of fullness or minor digestive discomfort. As with any supplement, it’s recommended to consult a healthcare professional before starting, especially if you have medical conditions or dietary restrictions.
-
Collagen peptides are small, easily digestible pieces of collagen protein that have been broken down through a process called hydrolysis. This makes them more bioavailable, meaning your body can absorb and use them efficiently. Collagen peptides help support healthy skin, hair, nails, joints, and overall connective tissue by providing the essential amino acids your body needs to produce its own collagen.
