🌿 What is a 3-in-1 Collagen Complex?
What is Collagen with Biotin & Vitamin C?
Marine Collagen with Biotin and Vitamin C is a daily supplement formulated to support beauty from within. It combines Type I collagen peptides, biotin, and vitamin C — three nutrients commonly associated with healthier-looking skin, hair, and nails.
As we age, collagen levels naturally decline, leading to wrinkles, sagging skin, and joint stiffness. Biotin can also be depleted by stress, diet, or lifestyle, potentially affecting hair and nail strength. This formula helps replenish what’s lost — while encouraging your body to make more of what it needs to stay vibrant.
Together, collagen and biotin form a powerful duo for external beauty and internal resilience, with vitamin C amplifying their effectiveness.

Hydrolysed Marine Collagen Peptides (500mg per capsule)
Our wild-caught, freeze-dried and hydrolysed Marine Collagen provides a clean source of Type I collagen—the key protein in skin, hair, nails, and joints. Hydrolysis helps break the collagen down into peptides for easier absorption and better results in elasticity, hydration, and joint comfort.

Vitamin C (Ascorbic Acid, 50mg)
Included to support natural collagen production, Vitamin C helps the body effectively utilise collagen peptides while also acting as an antioxidant. This promotes skin brightness, immune defence, and cellular protection — essential in any beauty-focused formula.
Biotin (D-Biotin, 10,000μg)
Biotin is well-known for its role in maintaining healthy hair, skin, and nails. At 10,000µg per capsule, this high-strength dose supports visible improvements in hair thickness, skin smoothness, and nail strength. It works alongside collagen and vitamin C to enhance total beauty from within.

Is there a downside to taking marine collagen?
Marine collagen is well-tolerated by most people but should be avoided by individuals with seafood allergies. It’s important to follow the recommended dosage and check for any sensitivities.
What happens to your body when you start taking collagen?
Over time, your body may begin to show improvements in skin texture, hydration, joint mobility, and overall tissue strength. Most users report smoother skin and reduced stiffness within 4–8 weeks of consistent use.
What is better for thinning hair, biotin or collagen?
Both are helpful — biotin supports hair growth and strength, while collagen reinforces the structure of hair follicles. Together, they form a more effective approach for thinning hair than either alone.
What to avoid when taking collagen?
Avoid taking collagen with large doses of caffeine or alcohol, as these can interfere with absorption. It’s best taken with water and food.
How long does it take for collagen and biotin to work?
Most people notice visible results within 6–8 weeks of daily use. Hair growth, stronger nails, and smoother skin are the most commonly reported benefits.

What are the symptoms of biotin deficiency?
Signs of biotin deficiency may include thinning hair, brittle nails, dry skin, fatigue, and in severe cases, neurological symptoms. Supplementing with biotin may help correct this.
What side effects does biotin have?
Biotin is generally safe, but in high doses it may cause mild digestive discomfort or interfere with certain lab test results. Always follow the recommended dose.

Marine collagen is highly bioavailable and rich in Type I collagen, which is ideal for hair and skin health. When combined with biotin and vitamin C, it offers targeted support for thinning hair.
