It's great quality. I suffer from acid reflux and take acid inhibitors, so I need sublingual B12 supplements, and this is the best I've used. Its latest 5000mcg formula with B1 and B6 gives me energy and helps my nervous system. It has a pleasant taste. I take it for 8 days, 10 drops per day, which is enough for my 49 years. Review: Actually helps (from a skeptic) - I was hesitant to order, but after giving it a try I find it quite amazing. Relief from nerve tingling in my feet started on 1st application. I couldn't believe it. I hope it just keeps getting better and better.

I only wonder, how can I manage to hold under my tongue longer, than 3 seconds. I think because of the flavor my mouth fills with saliva instantly and I can not help myself, but swallow it. I wish I could hold it under the tongue as long as it recommended. ## Frequently Bought Together - Vitamin B12 Sublingual Liquid Drops (5000 mcg) Plus B1 & B6 in Fastest Absorption Way.
