What exactly is "yeast culture?" Yeast Culture is an ingredient produced by fermenting selected liquid and cereal grain raw ingredients with bakers yeast (Saccharomyces cerevisiae) and drying the entire culture-media without destroying the yeast factors, B-vitamins and other fermentation products. It is used in a wide variety of animal feeds including dairy, swine, beef, horse, poultry, aquaculture and petfoods.

In manufacturing yeast culture, the following ingredients are used: Saccharomyces cerevisiae yeast and the media on which it was grown consisting of ground yellow corn, hominy feed, corn gluten feed, wheat middlings, rye middlings, diastatic malt and natural sweeteners.

The live yeast and yeast culture used in the manufacturing of HorseTech's Yeast+ product are both Made in the USA!
