Versele Laga Oropharma Avi-Chol is a dietary supplement for birds for an optimal liver function and a good moult. It is a unique liver tonic based on sulphuric amino acids, biotin, sorbitol and vitamin B12.

Optimal liver function is crucial to your bird's health. In young birds, where the body is still in full development, the liver is subject to extra strain due to the greater need for energy, proteins, vitamins, fats and hormones. TIP for administering via eggfood: mix the dose of Avi-Chol first in the water which will be used to moisten the eggfood until you obtain a homogenous mixture.
