Under stress horses often become vitamin B deficient due to the loss of vitamin-producing gut microbes. B-Good Paste is designed to increase vitamin B levels to meet the horses daily requirements where dietary and microbial production is not adequate to meet needs. The live yeast probiotics in B-Good Paste help to re-establish gut microbial populations during and after stress periods. This also has a positive impact on vitamin B levels available to the horse in days to come.
