Description

Give your dog complete daily support with Celltail Longevity Formula, a premium complementary feed designed to promote mobility, vitality, digestive balance, and overall wellbeing. This soft-chew supplement combines clinically explored ingredients with high-quality nutritional components to support healthy ageing and everyday comfort in dogs of all breeds and sizes.

Formulated with a blend of Type II Collagen, Green-Lipped Mussel, Salmon Oil (Omega-3), Inulin, L-Carnitine, β-glucans, Boswellia serrata, Turmeric, Vitamin C and the probiotic Bacillus velezensis, this formula targets multiple physiological pathways involved in joint function, gut health, natural defenses, and cellular balance. Each soft chew is crafted using natural flavouring and a dog-friendly base of sweet potato, pea flour, vegetable glycerin, lecithin, and tapioca starch to ensure excellent palatability and easy daily use.

Type II Collagen and Green-Lipped Mussel provide essential structural nutrients that support normal cartilage maintenance and joint movement. Salmon Oil, naturally rich in Omega-3 fatty acids, contributes to skin and coat quality while supporting mobility and general vitality. Inulin, a natural prebiotic fibre, works alongside the stable spore-forming probiotic Bacillus velezensis to support digestive comfort and a balanced gut microbiome.

To enhance daily wellbeing, L-Carnitine assists normal energy metabolism, while Turmeric, Boswellia, Vitamin C, and yeast β-glucans contribute natural antioxidants and plant compounds that support physiological balance.

Produced in strict compliance with EU feed regulations, Celltail Longevity Formula clearly declares all ingredients, analytical constituents, and approved additives. This guarantees transparency, quality, and trust for pet parents seeking a reliable longevity and mobility supplement.

Nutrition plays a key role in how dogs age

As dogs grow older, changes in their joints, digestion, immune system, and cellular health happen gradually. Supporting these systems with targeted nutrients helps maintain mobility, vitality, and overall wellbeing.

Key Scientific Insights:

80%

of a dog’s immune system is located in the gut, meaning digestive health strongly influences overall wellbeing.
(Veterinary immunology consensus)

Title

90%

of senior dogs show a measurable decline in natural collagen production, impacting joint comfort and mobility.
(Connective tissue biology research)

Title

70%

of ageing dogs experience increased oxidative stress, which affects cells throughout the body including joints, skin, and connective tissue.

Support Your Dog’s Health As They Age — From Joints to Gut to Energy

Joint & Cartilage Maintenance

Over time, joint tissues naturally experience wear. Our formula supports the normal renewal of cartilage and helps maintain comfortable movement by supplying the body with structural nutrients and omega-3 fatty acids essential for joint health..

Gut & Immune Balance

A healthy microbiome is central to overall wellbeing. The prebiotic–probiotic combination in the formula helps maintain digestive comfort while supporting natural immune defenses from within the gut, where most immune cells are located

Cellular Vitality & Antioxidant Defense

Dogs’ cells face oxidative stress daily, especially as they age. Plant antioxidants, vitamin C, and omega-3s help support normal antioxidant capacity, contributing to energy, coat quality, and overall vitality.

Daily Energy & Metabolic Support

Ageing dogs often experience slower metabolism and reduced activity levels. L-Carnitine helps support normal energy use and contributes to active daily living — so your dog feels ready for every walk, run, and adventure.

The Result: Whole-Body Longevity Support

When these systems — mobility, digestion, immunity, cellular vitality, and energy — work harmoniously, dogs stay healthier for longer. That’s the foundation of the Celltail Longevity Formula.
