To support normal serum cobalamin and folate levels in dogs and cats.


New look, same trusted Protexin Veterinary products.



Cobalaplex 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, healthy life.



  • 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. As a result, proliferating cells such as erythrocytes, leukocytes and enterocytes have a high requirement for folic acid.
  • 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.
