Metformin is GREAT! I have zero metabolic issues, no pre-Diabetes/Diabetes. I began taking metformin experimentally about 10 years ago when I was in my late 50s. I have taken as much as 1500 mg per day, but now typically 1000 mg in the evening. I started very slow with 250 mg a day and worked up. If you do a search for metformin study, you begin to see many different research studies with this product. Recently it seems to be found to prevent hospitalization for people who had covid. There are many different cancers that it seems to be likely to reduce the development of. Has potential benefits for the eyes as far as macular degeneration and on and on. Do your own searches. A lot of the.com execs are taking metformin as a potential extender of healthy older years and potentially an extended lifespan. I think there’s some bigger stuff out there that can do more but for now metformin is a good choice for many people.
