That’s tough. I might seek opinions from top rated experts who know the research.

One of my early Endocrinologists was the head of the Endocrinology dept at a large, well known medical school. He did research, conducted clinical trials, was a noted expert in his field, specifically diabetes, so I gave his advice a lot of weight and trusted his opinion. (Still do.) I’m the same way about my cornea specialists.

I hope you find helpful information that you feel comfortable with. Please post what you discover.
