Collagen makes up about 30% of total protein mass, forming the framework of skin, bones, cartilage, tendons, ligaments, blood vessels, the cornea and teeth. Of the 28+ known collagen types, types I and III are by far the most common — type I in skin, bones, tendons and corneas; type III in blood vessels, internal organs and muscle. From around age 25, natural production declines by roughly 1–1.5% a year, showing up as reduced skin firmness, weaker joints, lower bone density, thinner hair and brittle nails.

Hydrolysed collagen (collagen peptides) is made by enzymatic hydrolysis, breaking long collagen chains into low-molecular-weight peptides that absorb far more easily than native, unprocessed collagen — studies show these di- and tripeptides reach the bloodstream and are distributed to target tissues (skin, cartilage, bone). This formula adds vitamin C (calcium ascorbate, 30mg per dose, 33% NRV), an essential cofactor for the enzymes prolyl and lysyl hydroxylase involved in collagen fibre maturation — without it, the body cannot properly form collagen’s triple helix.

Collagen peptides contribute to skin hydration, firmness and elasticity and support cellular renewal; support cartilage integrity for joint comfort, particularly for active people and athletes; type I collagen makes up about 90% of bone’s organic matrix, giving bones flexibility alongside minerals like calcium; and collagen supplies amino acids essential to keratin, the structural protein of hair and nails. Type III also supports the structure and elasticity of blood vessel walls.

Made by Doctor’s Best, a US brand founded in 1990 by a physician, known for research-based formulations in GMP-certified facilities. This collagen is high-quality, non-GMO and gluten-free. Take 3 tablets a day, ideally on an empty stomach or between meals with a large glass of water, for at least a 3-month course. Support the formula with a vitamin-C-rich diet (citrus, kiwi, peppers, broccoli).

Not suitable for vegetarians, vegans, or people with a beef protein allergy. Do not exceed the recommended daily dose. If pregnant, breastfeeding, or on medication, seek advice from a healthcare professional. Store in a cool, dry place away from direct light.

How long before I see results?

Usually 4–8 weeks of regular use, with a 3-month minimum course recommended for lasting effects on skin, joints and bones.

Is it suitable for people with gluten intolerance?

Yes — this formula is gluten-free and non-GMO, suiting people with gluten intolerance or coeliac disease.

Beef vs. marine collagen — which should I choose?

Beef collagen is rich in types I and III, covering skin, bones, joints and connective tissue broadly, and is generally more affordable. Marine collagen is mainly type I, often favoured for skin, with smaller peptides for fast absorption. For a broad, versatile approach, beef collagen types I and III is an excellent choice.
