Ester-C® (Calcium Ascorbate) - Gentler on Stomach, Faster Absorption & More Stabilty

  • Does your horse need more immune support?
  • Is your horse over 17 years old?
  • Does your horse need joint/bone support?
  • Are allergies a problem for your horse?

This formulation is a unique, patented ascorbate complex bound with Calcium Carbonate. Naturally processed in purified water without the use of alcohol or acetone solvents. This makes Ester-C® a more readily absorbed form of Vitamin C. Ester-C®, a well-known anti-oxidant has been shown to aid in:

  • Reducing joint cartilage degeneration
  • Decreasing susceptibility to infections

Ester-C® has up to more metabolic activity than standard Vitamin-C (ascorbic Acid). Contains 28,375 mg Ester-C®/oz. 


  • Stability -- Ester-C® has a shelf life up to 5 years. Typical shelf life of Vitamin C (ascorbic acid) is 6 months to 1 year depending on storage, as it is sensitive to heat, light and air.
  • Non Acidic -- Ester-C® is non acidic like Vitamin C (ascorbic acid), so it's gentler on the stomach.
  • Absorption -- Studies indicate when the same levels of Ester-C® and Vitamin C were given, the Ester-C® absorbed twice as fast and indicated levels in tissues to be greater than Vitamin C.


Active Ingredients: Ester C® -- 14,000 mg per enclosed measure.
