Dr. Mercola Methyl B12 Energy Boost Spray, 0.98 Fl. Oz. (29 mL), 39 Servings, 1,000 mcg Per Serving, Dietary Supplement, Supports Mental Focus, Non-GMO

Quality item, tastes great too!

Have bought this a second time, I’m noticing energy increase. I’ve been taking a record twice a day of my supplements along with my long walk activities, blood pressure, heart rate and weight. If I take this before my evening walk I can climb the stairs at the exit route easier. My records are showing this benefit.

pros, works fast, pleasant taste. dosage is 4 sprays, i take 2-3 in the morning. clearer thinking, better concentration, more alert, without getting " jittery " cons, once you open the bottle, effectiveness goes down within a month or so. i keep mine in the fridge - maybe it will last longer. been using this for several years, will continue to do so

The product is very quick to impact on the body. After research this one seemed the best although more expensive than other products but it is worth it

Actually works- my blood labs show the change in B12 and this absorbs much better than a tablet.
