I know the many years I was a diabetic, metformin depletes vitamin B12. Anyone on Metformin? I began using NutriBiotic Grapefruit Seed Extract, it's far better than Metformin and no side effects. I'm no longer a diabetic but it took leaving the Standard American Diet (SAD), my food is plants, nuts and seeds. I lost more than 170 lbs.
The quality of the product seems very decent and the size of the caps are relatively small. I took it first before going to bed and I felt like it made it a little troublesome to get to sleep because it is supposed to give you energy so now I am taking it first thing in the morning. The only disadvantage is that you can feel the taste of the product when you swallow but nothing too concerning.
So far I have no complaints with this product after using for two months. It has helped along with other B vitamins for inflammation and joint issues. Ingredients seems safe and I’d definitely reorder. Overall good quality and amount for the price.
