Cats and dogs age differently, move differently, and have different temperaments — but they share one biological truth: collagen is the structural protein their entire body depends on, and they both start losing it earlier than most pet owners realize. Dull coats, dry skin, stiff joints, and declining energy are all collagen depletion showing up in real time. Kriath’s Liquid Collagen for Cats and Dogs was built to reverse that — with a clean, liquid formula that absorbs fast and works across both species without compromise.
Why Liquid Over Chews or Capsules? Liquid collagen absorbs significantly faster than solid forms. It bypasses the digestive breakdown that degrades collagen in tablets and chews, meaning more active collagen actually reaches your pet’s tissue. The dropper gives you precise, consistent dosing every time — no guessing, no waste.
The Ingredients
🧬 Collagen (Marine/Fish-Derived) — Fast-absorbing collagen peptides that go directly to work replenishing the structural protein behind healthy skin, a lustrous coat, strong connective tissue, and well-cushioned joints. Marine collagen is among the most bioavailable forms available for both cats and dogs.
💧 Plant Glycerin — A natural humectant derived from plants that keeps the formula smooth, palatable, and effective. It also supports moisture retention in the skin — working alongside collagen to restore the hydration barrier from within.
🍋 Citric Acid — A natural pH stabilizer and preservative that keeps the formula bioactive, fresh, and effective throughout its shelf life without harsh chemicals.
🛡️ Potassium Sorbate & Sorbitol — Gentle, pet-safe preservatives and palatability agents that maintain formula integrity and make it naturally acceptable to even the pickiest cats and dogs.
What It Does For Your Pets
- ✨ Promotes Skin & Coat Health — Collagen peptides rebuild the protein structure behind each hair strand and skin cell, restoring the shine, softness, and thickness that age strips away from both cats and dogs.
- 🦴 Supports Joint Flexibility — Daily collagen replenishment cushions the joints, supports cartilage integrity, and keeps your pets moving with the ease and range of motion they deserve.
- ⚡ Supports Overall Vitality — Collagen is involved in virtually every tissue in the body. When levels are restored, the effects show up everywhere — energy, coat, movement, and general wellbeing.
- 💧 Hydrates From Within — Plant glycerin and collagen work together to restore the skin’s moisture barrier, reducing dryness, flaking, and irritation in both cats and dogs.
- 🐾 One Formula, Two Pets — No need for separate supplements. One bottle, one routine, covering every pet in your home.
How To Give It Add the recommended drops directly to food or water once daily. The neutral, gentle flavor profile is accepted by most cats and dogs without resistance — including picky eaters. Use consistently every day for best results. Collagen benefits are cumulative and most visible after 4–8 weeks of daily use.
Who It’s For Cats and dogs of any age showing signs of collagen decline — dull coat, dry skin, reduced joint mobility, or low energy. Also ideal as a proactive daily supplement for younger pets, building a strong collagen foundation before the signs of decline appear.
60ml. One dropper. Every pet. Every day.
