suggestions for a pelleted vitamin b supplement

Need to add more B vits. But the super picky old man does not will not ever again eat anything soaked, liquid, or powdered only pelleted.
Any suggestions?

Ultra Cruz makes a Vit B1 pellet. My picky eater approves. I tried the inexpensive 30 single packs to bump up my Vit E order to free shipping.

Has your horse had a significant portion of his/her large intestine removed? Is the horse on a low-or-no-forage diet for some reason? If not, the microbes in the hindgut are likely (as in 99.9999999% of horses) producing more than sufficient B-vitamins (biotin potentially excluded) to meet the horse’s needs. What makes you think you need to add a b-vitamin supplement, and is there a particular vitamin you are concerned about?
