This careful combination of riboflavin, vitamin B-1, niacin, lipoic acid, and pantothenic acid allows your horse to burn carbohydrates and fats for energy during intense exercise, when oxygen isn’t enough.

*Lactanase is sold in individual packets, with 12 individual packets in a complete box. 


  • Supports strong metabolism and muscle function
  • Easy to administer powder
  • Provides necessary ingredients for the production of acetyl coenzyme A
  • Pre-activity supplement to get the best from your horse

Great Product!!


Latanase has made a major positive impact on my horse, I love it!! After hard work or a day of showing, I give my horse a lactanase packet and it helps him recover much quicker. I feel that his muscles are relaxed and ready to work!
