When horses with low reserves of certain nutrients are subjected to increased physical activity and/ or stressful situations, the resulting drain on their already reduced vitamin and amino acid reserves can give rise to altered behaviour and/ or loss of performance. Equiliser can help in these situations by replacing missing nutrients quickly, easily and effectively. Equaliser is an important combination of L-Trytophan, vitamins B1 and B6, niacin and organic magnesium, in a formulation conceived to meet the nervous system requirements during important periods of solicitation. Equaliser is equally a formula that complements a dry ration and assures a sufficient supply of nutritional elements for the nervous system.
