    Frequently Asked Questions

    Cartidyss® works at just 500 mg per dose versus 2,000+ mg for standard collagens because it combines enzymatic hydrolysis (for superior absorption) with added glycosaminoglycans that enhance skin nutrition. You get the same results with two capsules as competitors deliver with four or more.
    No mixing, no measuring, no cleanup—just take 2 capsules once daily with or without food. Take them anywhere: home, work, traveling. Zero preparation time, and you avoid the chalky texture and flavor issues that come with powder supplements.
    Unlikely. The lower 500 mg dose is gentler on your digestion than high-dose competitors, and the enzymatic hydrolysis breaks down collagen into smaller peptides for easier absorption. Taking just 2 capsules once daily also means you're not repeatedly overwhelming your system with protein throughout the day. (Always consult your healthcare provider if you have a sensitive digestive system.)
    No. This product uses a specialized natural citrus-scented desiccant that eliminates the typical fishy odor. Plus, the capsule format means you don't taste anything—you simply swallow and go.
    Expect meaningful results within 8-12 weeks with consistent daily use. Clinical studies showed 31% reduction in laugh lines, 26% reduction in crow's feet, and 38% increase in skin density over 90 days. Consistency is key—take your 2 capsules every day for at least 3 months to see optimal benefits.
    This Marine collagen is absorbed 1.5x better than bovine, is a unique Type II for skin health, avoids religious dietary concerns, and has a lower environmental footprint. This product uses Cartidyss®, sustainably harvested from fish cartilage off the coast of France.
    Most collagens are just collagen. This adds PureWay-C™ Vitamin C (233% more effective than regular vitamin C for collagen formation) and ApplePhenon® apple polyphenols (for antioxidant protection against skin damage). You get a complete skin nutrition package, not just collagen alone.
    Yes, it's backed by clinical research. A 90-day placebo-controlled study showed 31% reduction in laugh lines, 26% reduction in crow's feet, 38% increase in skin density, and 10% improved hydration. The collagen peptides and glycosaminoglycans are effectively absorbed within two hours and increase elastin production by 40%.

    Frequently asked questions

    What is Cartidyss?

    Cartidyss is hydrolyzed fish cartilage from skate (Leucoraja naevus, Raja brachyura and Raja clavata) sourced off Brittany, France. It supplies Type II collagen together with the glycosaminoglycans that occur naturally in cartilage: chondroitin sulfate, glucosamine sulfate and hyaluronic acid.

    How many capsules do I take, and when?

    Adults take 2 capsules once daily, with food or on an empty stomach. The label directs use for 3 months to see beneficial effects.

    Why is the dose only 2 capsules a day?

    The daily dose is 500 mg of Cartidyss from 2 capsules. The product page explains that the collagen is enzymatically hydrolyzed to a low molecular weight and combined with glycosaminoglycans, which is why it is used at a lower amount than standard collagen powders.

    Does it contain vitamin C?

    Yes. Each capsule contains 20 mg of PureWay-C vitamin C, 40 mg per daily dose, alongside 10 mg of ApplePhenon apple polyphenols.

    Does it smell or taste of fish?

    The product page states that a natural citrus-scented desiccant is used to control the fishy odour typical of marine collagen, and the capsule format means there is nothing to taste.

    Is it suitable for vegetarians?

    No. The collagen is from fish cartilage. The capsule itself is a vegetable capsule. The product contains fish and is labelled as an allergen.

    Who should check with a health care practitioner before taking it?

    The label states that anyone who is pregnant or breastfeeding should consult a health care practitioner before use, and that some people may experience gastrointestinal discomfort.

    How long does one bottle last?

    At 2 capsules per day, the 60-capsule bottle lasts 30 days, the 120-capsule bottle 60 days and the 180-capsule bottle 90 days, which is the three-month period the label directs.

    Has the ingredient been studied in people?

    Yes. The clinical references for Cartidyss are listed under Research on this page, including a 90-day double-blind placebo-controlled study on skin published in Molecules in 2021.
