Oh! It sounded like you were giving him a tablet or something. The capsule is fine (but check at local health food store - I buy the loose powder there and it is SO much less expensive it's ridiculous). The right dose is 1/4 teaspoon. And just put it in the bowl first, and add a little water to it - about a teaspoon or so. It'll gel up in less than a minute, really. Then add the other stuff and mix it up. The issue with nutrient absorbtion..... the way I'm getting around that is I'm not feeding it with a meal. I feed it separately, a couple of hours after the meal as a treat. According to my holistic vet, there's no issue with long term use, and a lot of benefits. I haven't done a lot of research on it, but here's the LittleBigCat article (Dr. Jean Hofve) on it: http://www.littlebigcat.com/health/slippery-elm/
...and based on what she says, you'd want to make sure to give it a couple of hours before or after the antibiotic.
