Magnesium and L-Tryptophan feed supplement for horses to support a healthy nervous system.

A sufficient intake of Magnesium is a prerequisite for the proper functioning of the muscular and nervous systems. If there is a deficiency, the transmission of important impulses between the cells is disrupted, which can lead to nervousness.

Magnequin combines Magnesium with Essential Amino Acid L-Tryptophan and Vitamin B12 to support the well-being of the horse and to support the central nervous system.
