Ascorbic acid (Vitamin C)

Ascorbic acid (Vitamin C) is a water-soluble antioxidant compound, which protects cells against oxidative damage and improves immune system function. Vitamin C is believed to play a role in protein, lipid and carnitine synthesis, maintaining blood vessel integrity, and immune function.

Vitamin C may also act as a co-antioxidant with other antioxidants by synergistic effects. There is a close relationship between Vitamin C with Vitamin E.

Emerging research have shown that adult poultry are capable of synthesizing vitamin C to meet their requirements under normal conditions. However, during stressful conditions, the vitamin C present in their immune cells is quickly depleted.

Adding vitamin C to the diet is beneficial for birds under any sort of stress, including heat stress from exposure to hot weather. It has been shown to help enhance their immune system and alleviate metabolic signs of stress.

Storage/Stability: Protect from air and light. Ascorbic acid will slowly darken upon light exposure. Slight discoloration does not affect potency.
  • 20-40 mg/kg given daily to weekly, orally or IM.
  • Laying hens under heat stress will need 200-500 mg/kg added to their diet per day.
  • Very large doses may result in diarrhea and potentially urolithiasis.
