More information

Protexin Veterinary Denamarin for Large Dogs is a high-potency liver support supplement designed for dogs 15kg and over. Combining SAMe (S-adenosylmethionine) and bioavailable silybin, Denamarin protects liver cells from toxin damage while promoting natural cell recovery. Ideal for large breeds needing targeted liver care or senior dogs facing age-related cognitive decline, it delivers comprehensive support for liver, brain, and immune health.

Why choose Denamarin

  • Dual-Action Support: Blends SAMe and silybin to protect liver function and maintain brain clarity.
  • Enhanced Silybin Absorption: Uses a specialized milk thistle extract absorbed far better than standard extracts.
  • Enteric Protective Coating: Ensures tablets pass safely through stomach acid for complete absorption in the gut.
  • Vet-Recommended: Science-backed liver supplement developed by Protexin Veterinary.

Common uses

  • Large dogs diagnosed with liver disease or elevated liver enzymes.
  • Liver protection during or after strong veterinary medications.
  • Senior large dogs showing signs of memory loss or cognitive decline.
  • Daily antioxidant support for ongoing liver cell repair.

Key ingredients

  • SAMe (S-adenosylmethionine): Powerful antioxidant that rebuilds liver tissue, aids detox, and boosts brain health.
  • Silybin (Milk Thistle Extract): Highly absorbable compound that supports healthy liver enzymes and cell structure.

    Dosage & administration

        • Timing: Give on an empty stomach (at least 2 hours after feeding, and 1 hour before the next meal).
        • Give Whole: Do not crush, break, or chew, as this destroys the enteric protective coating.
    Dog Weight Daily Dose
    15kg – 29.9kg 1 tablet daily
    30kg – 54.9kg 2 tablets daily
    55kg and over 3 tablets daily

    Or strictly as directed by your veterinarian.

    Storage instructions

      • Store in a cool, dry place below 25°C.
      • Keep tablets in original blister foil to protect against moisture.
      • Keep out of reach of children and household pets.

    FAQs

    Q: Why does Denamarin need to be given on an empty stomach?
    A: An empty stomach allows the tablet to move quickly into the intestine for fast, maximum absorption.

    Q: Can I crush or split Denamarin tablets for large dogs?
    A: No. Denamarin must be swallowed whole. Crushing ruins the protective enteric coating required to pass through stomach acid.

    Q: Is this large dog formula safe for smaller pets?
    A: No. This strength is formulated specifically for dogs over 15kg. Use the Small or Medium Denamarin options for lighter pets.
