Cobalaplex is an oral supplement that has been designed to help support normal serum cobalamin (vitamin B12) and folate (vitamin B9) levels in dogs and cats, helping them to enjoy a happy and healthy life.

Presented as sprinkle capsules that can either be given whole or opened and sprinkled onto food, Cobalaplex has an artificial chicken flavour to ensure excellent palatability.


  • Cobalamin (vitamin B12): Cobalamin is a water-soluble vitamin that plays an important role in many physiological processes including cellular metabolism, DNA synthesis, amino acid metabolism, fatty acid metabolism and erythrocyte formation
  • Folic Acid (vitamin B9): Folic acid is a synthetic form of folate, another important water-soluble B vitamin that is essential for DNA synthesis and repair thus playing a key role in cell division and growth
  • Preplex Prebiotics: A prebiotic combination of fructo-oligosaccharide (FOS) and acacia (gum arabic), which helps to support a healthy gastrointestinal microbiota and thus aiding the maintenance of optimum serum folate and cobalamin levels
  • Artificial chicken flavouring: To improve palatability and compliance, without any concerns for animals with food allergies or intolerances
