Nutrition Strength Vitamin K for Dogs with K1, K2 (MK4 & MK7) and D3 - 120 Chewable Tablets

Key Ingredients and Their Benefits

This advanced supplement combines four potent forms of vitamin K with vitamin D3 to support your dog's wellbeing. Vitamin K1 (Phytonadione) is the primary form involved in blood clotting, helping to maintain normal coagulation and circulatory health. Vitamin K2 as MK4 (Menaquinone-4) is a short-chain form that is rapidly utilised by the body, playing a role in bone metabolism and soft tissue health. Vitamin K2 as MK7 (Menaquinone-7) is a long-chain form with a longer half-life, providing sustained support for calcium transport and helping to direct calcium to bones rather than soft tissues. Vitamin D3 (Cholecalciferol) is the preferred form for dogs; it enhances calcium absorption from the gut, supports a healthy immune system, and contributes to muscle function and bone density. Each chewable tablet delivers a precise, vet-formulated dose that is both effective and palatable.

What Makes This Formula Different?

Many dog multivitamins offer only a single form of vitamin K or minimal D3. Our advanced formula includes both K1 and K2 in two bio-available forms (MK4 and MK7) to ensure comprehensive coverage. The addition of D3 amplifies calcium absorption, making this a true bone and heart health powerhouse. Manufactured in a cGMP-certified facility in the USA, each batch undergoes rigorous quality testing for purity, safety, and potency. The chewable tablets are designed with a palatable flavour that dogs love, making supplementation easy even for picky eaters.

How Do K1 and K2 (MK4, MK7) Differ for Dogs?

Vitamin K1 is primarily involved in blood clotting and is found in green leafy vegetables. Vitamin K2, on the other hand, is more active in bone and cardiovascular health. MK4 is a short-chain form that acts quickly and supports cellular functions, while MK7 has a longer duration of action and is effective at directing calcium to bones. By including all three forms, our formula provides both immediate and sustained benefits, ensuring your dog gets the full range of K-vitamin support.

How Vitamin K and D3 Work Together for Calcium Absorption

Calcium is essential for strong bones, but it must be properly managed. Vitamin D3 helps your dog absorb calcium from food, whilst vitamin K2 activates proteins that bind calcium to bone matrix. Without enough K2, calcium may be deposited in soft tissues like arteries and organs, potentially compromising heart health. By providing both K1, K2 (MK4 and MK7), and D3, this formula supports the natural process of calcium metabolism, promoting skeletal strength without the risks of calcification elsewhere. This balanced approach is especially valuable for large and giant breeds prone to bone and joint issues, as well as ageing dogs who experience natural changes in calcium regulation.

Recommended Dosage and Usage

For best results, follow the dosage instructions on the product label. The recommended serving size is based on your dog's weight: typically one tablet per day for dogs under 23 kg, and two tablets for dogs over 23 kg. Tablets can be given directly as a treat or crumbled over food. Always consult your veterinary surgeon before starting any new supplement, especially if your dog has a medical condition or is taking medication.

Why Your Dog May Need Vitamin K and D3

Every dog deserves a strong foundation for lifelong health. While a balanced diet provides many essential nutrients, factors like age, breed, and lifestyle can create gaps. Vitamin K and Vitamin D3 are two critical fat-soluble vitamins that play a complementary role in your dog's wellbeing. Vitamin K supports proper blood clotting and helps direct calcium to the bones where it belongs, while Vitamin D3 aids calcium absorption and immune function. Together, they form a powerful team for skeletal strength, cardiovascular health, and overall vitality. Many senior dogs, large breeds, or pets recovering from surgery may benefit from additional support. Our advanced formula combines both Vitamin K1 and the full spectrum of K2 (including MK4 and MK7) with Vitamin D3 to deliver comprehensive care in a delicious chewable tablet.
