This post may not be the post to explain the general idea, but essentially, these products are often called “insulin mimickers” because they help your body better handle blood sugar.
Health-wise, keeping blood sugar down is one of the most important things you can do for longevity and staying away from metabolic syndrome. The average person who doesn’t train should of course just eat less carbs if their blood sugar is sky high all the time, of course, but good berberine works as well (if not sometimes better) than prescription drugs like Metformin for the same purpose.
Body composition wise, these supplements can theoretically help you shuttle those sugars into muscle tissue instead of fat cells, assuming you’re training hard.
Training-wise, when you take this, and then carbs, then go train, you can get some legendary pumps, because of the aforementioned affect. The agmatine will also be nice in this one for that purpose.
It’s always good to have at least one GDA in the house to take before you go to a cheat meal.
The issue is if you don’t eat carbs (which is a concern with this label!!! It doesn’t say to eat carbs!!!) or not enough carbs, your blood sugar can drop and you can go hypoglycemic, which can be a seriously bad situation.
This is CLEARLY an advanced product, which is why we say in the blog post that 3-4 caps should probably be fine for starters, especially if you’re not crushing 150g carbs or something crazy like that.
Hope that helps explain in general without citations
