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.

I wanted to be able to take these at night along with my other vitamins but they actually give me a significant boost of energy and keep me awake so I'll be taking them in the morning.

Good value for money. Hard to to tell sometimes whether it gives more energy, but I think it does.

This product is very good for memory

Vitamin B-12 is an essential vitamin for the body. Supports energy metabolism, indispensable for the health of the nervous system, vital for the formation of red blood cells.

The product is just fire. Low stock price, rich set of vitamins and minerals, convenient packaging. The first thing I noticed was that the children began to feel better in the morning. We started waking up before the alarm clock in excellent condition.

Antacid medications cause a deficiency of B12, and this is an excellent option that contains a quantity of 250 tablets

vit B12 is a great ally in the fight against fatigue

Super! Great product! Our family loved it! Excellent result! We will order more for parents! Definitely recommend!
