helps with balance
I used this formula on my cat that had a problem with her gums. The vet saw her twice for this, and gave her an antibiotic both times to help with the inflammation. The day after her second injection her tooth fell out. So this was a tooth problem, not a gum problem. I have had luck with about half of the homeopathic preparations I have used over the years. This preparation is designed for gums, not infected teeth, so I still stick by homeopathic remedies as a non-toxic option for care for both me and my cats.

I have been taking multi - two for several years. It has helped my overall health. I had trouble standing on my feet with pain and my daughter asked me to try them and the first three days I saw little improvement but on the fourth or fifth day I got up one morning feeling better and no pain.
