There’s evidence that having HIGH BLOOD GLUCOSE speeds up the aging process and makes us more vulnerable to both bacterial and viral infections. If our blood sugar is high, we’re more likely to become infected with COVID-19 and to have bad results if we do. More info.

The body also responds to high glucose by producing more insulin.  Chronically high blood sugar can result in insulin resistance, and in higher mTOR activity –– which is also associated with a shorter lifespan.

There are a number of things we can do to lower our blood glucose. Some of them have the additional advantage of lowering mTOR. They include:

  1. Exercising.
  2. Eating a low-carbohydrate diet.
  3. Eating a ketogenic diet (high in fat, moderate in protein, very low i carbs). (Ketogenic diets are a specific variety of low-carb meal planning. They can improve blood glucose levels, moderate some of the symptoms of diabetes, and reduce the need for insulin).
  4. Taking metformin.
  5. Taking Berberine (similar in many respects to metformin, though its mechanism is different. (usually take with milk thistle)
  6. Taking Ceylon cinnamon (Note: Cassia cinnamon can be toxic and cause liver problems. Ceylon cinnamon is considered safer.
  7. Taking Chromium (may be helpful for people with prediabetes and insulin resistance).
  8. Taking Benfotiamine (an activated form of vitamin B1 (thiamine) –– controls many of the symptoms of diabetes)


I was told that I was pre-diabetic a couple of years ago ––– possibly because I was taking a lot of niacin, which tends to raise blood glucose over time. I reversed it (while still taking niacin) by exercising more and by taking chromium and berberine.

Since then, I’ve tried a number of different approaches to keeping my blood glucose levels low, including: 

  • Monday, Wednesday and Friday: taking berberine and milk thistle together. 
  • Tuesday and Thursday: taking benfotiamine and Ceylon cinnamon  together (and sometimes also taking chromium picolinate)
  • When eating a sweet meal (such as dark chocolate and berries): any or all of the above.
  • So far it’s working well. My blood glucose is well out of the danger zone for prediabetes.
