    The Absolute Proof

    As the UK's #1 collagen experts, we ran the largest, most robust clinical trial of a collagen supplement ever.

    The trial was independent, peer-reviewed (validated by other medically-trained professionals) and placebo-controlled (results compared to those who weren’t taking collagen). The trial featured 130 people over 12 weeks and gathered over 30,000 data points.

    The results, proved our expert-backed collagen Absolute-ly works!

    Within 6 weeks, participants saw:

    65% agreed skin feels replenished and restored*

    54% agreed skin looks and feels firmer*

    46% boost in skin elasticity*

    19% improvement in skin evenness*

    8% improvement in fine lines and wrinkles*

    After 12 weeks, participants saw:

    100% saw an improvement in fine lines, wrinkles and skin evenness*

    60% boost in skin elasticity*

    90% felt that their skin was replenished and restored*

    37% improvement in hair shine*

    32% reduction in hair damage*

    *Based on a 12-week clinical study with 130 participants.

    These results confirm that Absolute Collagen delivers real, visible benefits for skin and hair. For full results, you can see the clinical paper on our website

    How To Take

    One sachet a day is all you need for best results.

    Each 10ml sachet delivers 8000mg of high-quality marine collagen peptides - your optimal daily dose. Mix into your favourite food or drink, or take it on-the-go straight from the sachet - just rip and sip (easy!).

    Ethically & Sustainably Sourced

    Our ethically and sustainably-sourced marine collagen is safe, pure, and produced in an ethical, environmental and socially responsible way - from source to sachet:

    • Single origin So, it comes from within a 100-mile radius of the processing facility.
    • From farmed vs wild-caught fish. It's a by-product of the global fish industry and doesn’t further contribute to biodiversity or habitat loss.
    • Manufactured in the UK with 100% natural ingredients. It’s Halal-certified, and doesn't contain gluten, lactose, and artificial additives.
    • Sourced from an environmentally responsible, world-class facility - known globally for their patented hydrolysation technology and exceptionally high purity.
    • Produced through female-led suppliers that have strict animal welfare and traceability standards.
    • From a fully certified manufacturer accredited for quality, environmental and social standards.
    • Processed at source from Asia - reducing our environmental impact vs those who ship their heavy-source material to process their collagen in the EU, before shipping to the UK.
    Ingredients

    Our liquid supplement contains 8000mg of high-grade marine collagen, up to 120mg of vitamin C*, doesn't contain gluten, lactose, and artificial additives, and has only 36 calories with 7.7 grams of protein.

    Allergy advice: For allergens see ingredients in bold.

    *Vitamin C contributes to normal collagen formation for the normal function of skin. Enjoy as part of a healthy, balanced diet and active lifestyle. 60mg vitamin C = 75% of your daily NRV. 120mg of vitamin C = 150% of your daily NRV (Nutrient Reference Value).

    How Collagen Works

    As you age, your body makes less collagen – the protein that helps skin stay firm, smooth and strong. Absolute Collagen helps support what biology’s slowed down on, with premium hydrolysed marine collagen and Vitamin C that contribute to normal collagen formation.

    Once taken, our liquid marine collagen is absorbed and distributed to the deep layers of the skin (dermis). This helps stimulate and increase your body’s own natural collagen production, helping to improve skin rejuvenation, glowing skin, thicker hair and stronger nails.
