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.

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.

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.
