Hi Patti,

You can do a search of the messages for information on Probiotics as well as sedation. Assuming you bought this probiotic (https://shop.silverliningherbs.com/products/probiotic-for-horses) it may or may not be ok depending on what the 'processed grain by products' are, how much there are in a serving and how sensitive your horse is to them.  Many of our members use Absorb-All as a probiotic and as Dr. Kellon already told you (https://ecir.groups.io/g/main/message/270529) Equine Generator is fine if you need to use a probiotic. For information on sedation read this document in the file: https://ecir.groups.io/g/main/files/SEDATIVE%20EFFECTS.pdf.
