I use this everyday, 10 drops under the tongue and I’m good to go. Keep it in the fridge after you open it. I’m due for another one soon. I’ve been using it for probably around 8 months to a year. I definitely recommend it because it has more bioavailable types of B12 like the methylcobalamin and two others. Cyanocobalamin is the one that’s in all the B12 pills and your multivitamins but your body doesn’t readily absorb it as easily. This stuff has noticeably made a difference in my B12 levels on my bloodwork. And you don’t have to worry if you accidentally took too many drops because your body just gets rid of whatever extra isn’t necessary. This product is worth it for sure.

Love the taste!! It’s a wonderful B12 that gives me energy. Since I have the MTHFR gene, I need a B 12 that I can absorb.

The best oral vitamin B supplement I’ve ever used. Better than injections and easier.

Update: 05-09-25I'm updating this review because of the excellent customer service I received from this company. Because of the issues I had with the original product, they contacted me and offered a full refund. They did not ask me to change my review - it is my choice to upgrade it. I am totally impressed with their customer service.Not the greatest taste and the dropper tended to release product before ready - cleaned up several bright red spills. Think it was a defective dropper. No idea on effectiveness - more went on counter than went in me. Frustrating. Seemed like good ingredients according to the label but product delivery leaves a lot to be desired.

My Doctor recommended this for me ! Take as detailed !

The taste is awful and not sure I can stomach taking it. The original is better taste.

This works great I almost instantly feel the benefits .

I typically use about ten drops under my tongue, and before i'm halfway, I can already feel the difference. There's a boost in energy, and I can feel some clarity in my thinking. I also use a b twelve patch that has much more staying power, but for a quick pick me up before bed, I like this very much. I mentioned that it is energizing, so why would I take it before going to bed. I'm disabled and getting ready for bed, there's a lot of work at the end of the day when i'm so tired. This gives me just a little boost and doesn't affect my sleep at all.
