I do daily slippery elm, usually a bit before her dinner that has Metacam in it—like 15 min or so. I used to give it all together, but started staggering it a bit when we were doing the Minocycline for tick stuff so that it's full-on absorbable. I kind of doubt 15 minutes of delay does anything in the end, but it made me feel better at the time.
I also do Milk Thistle and SAMe and stuff like that, too. I'm glad she's feeling better after getting her eye fixed up!
