How long does a gallon and half gallon last for?
  • Gallon lasts 256 days (½ oz. once daily)
  • Half Gallon lasts 128 days (½ oz. once daily).
Can I top dress feed that is set up the night before? Reflex HA can be pre-mixed into the food prior to feeding, but it’s most effective if it's given while the product is still hydrated before it’s had a chance to dry out.
My horse is a picky eater, will they like the taste? Reflex Ha is unflavored, so most horses do not have any aversion to it on their feed.

  • Based on the recommendation of my veterinarian (Dr. Stuart Brown), I started my eventing horse, Sanimo, on Reflex HA. The results have been excellent, and Sanimo continues to feel fluid without any joint soreness throughout a grueling competition season. I now use Reflex HA for all of my competition horses!
