Query: CoQ-10 Softgels Strengthen Gums

When my teeth seemed to loosen somewhat and I faced gum surgery, a friend told me that years earlier, he had the same problem. His dentist told him about CoQ-10; my friend did research on CoQ-10 on the internet and gave it a try. It saved him surgery. I tried it, also, and it immediately worked. I don't know whether it will help everyone, but like my friend told me, he's going to continue using it and I agree. I used to take one softgel a day, but when I couldn't find the previous brand I used and my teeth once again loosened, I bought Solgar via Amazon. My teeth or gums once again strengthened immediately, but I find that I have to take 2 softgels a day now, 30 mg in each softgel. Whether it's the brand or my aging body, I don't know. As long as it works, I'll continue using the item; I was laid off my job and cannot afford dental surgery, if I can avoid it.
