Vitamin C (ascorbic acid) is a potent reducing agent and highly unstable in aqueous solutions, especially when exposed to heat, light, and oxygen. Furthermore, the presence of trace heavy metals and alkaline substances can elevate its degradation. Mono C has better stability, but remain highly sensitive to heat that may limit their effectiveness in feed processing. Among all Vitamin C formulations, Sodium Ascorbyl Phosphate, particularly monophosphates, provide the best bioavailability and stability, making them the preferred choice for feed additives. This formulation protects both Vitamin C from degradation and expands its scope of applications in animal nutrition.
