The best in years
I've been using this product since 2018. 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.

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. Update to be provided after one month...

No nasty flavor, works as it should
No nasty flavor, works as it should. 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.

Best product in the market. Hands down!
If you are used to taking regular Vitamin B12 pills from other brands, you will never go back after trying a good sublingual liquid form, such as this. Suffering from low levels of various vitamins and minerals, some of the downsides of B12 deficiency I have experienced over the years include low energy levels, brain function, irregular metabolism and mood. I have been taking sublingual B12 pills, but I decided to try this liquid formulation since it was the only one available in Amazon that included B1, B6 and B12 all in one product, to see if I got better absorption and results. I couldn’t be happier with this product! Among the many forms of B12 I've consumed, only this has produced a “boost” I can feel. Other forms of B12 I took previously helped me function regularly and maintained my energy levels stable, but I feel a “noticeable boost’’ in my energy since I am taking these drops. My brain and body are functioning better and I feel more clear and energetic. The flavor is pleasant, this natural product is definitely a great alternative to other pills or liquids.
