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

I have used this product for several years and have never been disappointed. It provides me a much-needed energy boost whenever I need it. Convenient too and preferable to a trip to your PCP for an injection. Using it sublingually provides a quick boost because it is absorbed almost immediately into your blood stream and does not have to run the gauntlet of your digestive tract. When used as directed, does all this without adverse side effects like caffeine products.

I had been feeling really run down so I decided to give this a try. I spray 5 sprays in my mouth in the morning and then periodically throughout the day if I’m feeling especially tired before I can quit what I am needing to do. I’m an active senior and this really helps me to keep going with the pep that I need! I’ve trusted Dr. Mercola for 20 years and the quality of his products is top notch!

Love this. Tastes good no bad after taste Easy To Use And not hard on your stomach

Easy to use. Taste is fine and I feel Dr. Mercola products are the best.

I was expecting a little more punch from this product. It does work with about 4-5 squirts. It wont give you a jolt or anything weird...just a mild increase in alertness. In the 80s there was something similar made called "Ener-B" that worked much better than this. So, it is a great idea it just doesn't have the same instant boost I was looking for. Not worth buying it again. I will give it 4 stars because delivery and packaging was excellent, the bottle itself says "Made in Canada", and safety tabs were secure. It is a three overall for use only.

Good stuff, great taste. Helps give you a little boost. Good for the immune system.

Mercola products are the best

Arrived defective with the safety seal broken and product everywhere, and apparently Amazon can’t send a replacement. Unfortunately the product itself says not to use if the safety seal is broken so it’s going in the trash. Highly disappointed. Would not recommend.
