The best I've tried!
UPDATE: This B12 no longer contains alcohol, and tastes better than ever! Seeing as I choose a mostly vegan diet, I've been hunting for the best b12 supplement for years now. I have had many liquids and lozenge forms over the years, and researched the best forms and methods of b12 for absorption. This is the first formula I've felt a notable effect from, even though it's the same dosage, technically. Shows how much the form (methylcobalamin), alcohol, and minimal other ingredients matter. If you are used to taking lozenges that stay under your tongue (for many minutes in some cases), you will never go back after trying a good liquid form, such as this. The alcohol that helps it absorb goes largely unnoticed, I can rarely taste it and don't mind it at all when I do. It compliments the delicious cherry flavor well. The cherry itself is not overwhelming or "medicinal" tasting like cherry NyQuil, but is strong enough that you don't forget it's under your tongue for the recommended 30 seconds. I genuinely look forward to squirting it under my tongue every day. Among the many forms of b12 I've consumed, only this has produced a "boost" I can recognize. I know the downsides of b12 deficiency, and have suffered from them multiple times. For me, this includes low energy levels, brain function, irregular metabolism/mood, etc. All forms have helped combat those, but I feel a "boost" from this stuff. I'm pretty attuned to notice subtle differences in how my brain and body are functioning and I feel more clear and energetic shortly after taking this. It feels very natural (appropriately...I mean "Why not?") and sustainable, like leveling up my base energy level, opposed to a spike from caffeine or similar that ultimately results in a crash to below the base level. I feel the other b12 I've had doesn't produce this effect, but just corrects my deficiency and keeps my functions regular and predictable, but not necessarily increased...if that makes sense. Honestly, the bottle is even great. It has all the information you could ask for printed on the tasteful, clear label. The dropper (maybe my favorite part) has ultra-convenient measurements right on it, so you're not left guessing how long the bottle will last or how much b12 you are getting. There's not too much or too little going on with the presentation. All in all, it truly seems no corners are cut in the making of this supplement. It follows good manufacturing practices, non-GMO, and MADE IN AMERICA! Batteries not included, your mileage may vary. Nevertheless, I absolutely believe in this product and feel I no longer have to search around for the best b12 for me. I hope this has been informative for you, and I'd like to thank you for reading.

Exactly what I need, and it tastes great. Not only that, but it will last well into the next month in case I forget to order.

The sudden burst quickly fades…
Well, when I tried it for the very first time, it worked fine. I got a sudden burst of energy! But then afterwards, the energy faded.

This is my favorite B12 supplement!
This really works for me! I was recommended by my doctor to try a liquid B12 vitamin, but the ones I could get at the drug store were a mix of B vitamins, too low dose (less than 1000mcg), and had a terrible, rancid berry flavor. This one can easily be dosed up to 500mcg using the graduation marks on the dropper (I recommend looking at it up against something white or very light in color, in a well-lit place to be able to read the brown marks with the red liquid in the dropper), and has a very nice natural cherry flavor (I love cherry). I have noticed a change in my energy levels for the better with this, when I never did with the drugstore ones. I now get this delivered regularly as I would not want to be without it.

Raises B12 Levels, Only take if you are deficient
This definitely raises your B12 levels. I became a vegetarian a fews years back so my Primary care physician started to track my Vitamin B12 levels as B12 is only naturally derived from meat. According to my health website the normal VITAMIN B12 range is 181 - 914 pg/mL As you can see 7 years ago (probably about the time I became vegetarian) to 2018 my B12 levels dropped. Was still in the normal range in 2018 but my doctor suggested I start B12 given I'm a vegetarian. After some research I settled on Methylcobalamin drops as from what I read sublingual (under the tongue) is better for absorption (though my doctor is not convinced of this). Additionally the Methylcobalamin is supposedly better for absorption than the Cyanocobalamin My B12 Level History 2012- 629 2017 - 341 2018 - 232 (started using this product after these results) 2019 - 862 (1 year after use) So there are the facts - In terms of how I felt - ZERO difference. I wasn't deficient so no change in energy, etc. There is a huge placebo effect for many people when they take B12, but unless you are truly deficient more does nothing for you. This product has 83,333% of the daily recommended value so it is a MASSIVE dose. I generally took much smaller amounts but even so am sure I was getting a huge amount. I'm going to cut back to a couple times a week with the smaller does and continue to take it quite simply because I am a vegetarian. As to the taste, they changed the formulation in the past year. At first it had some alcohol as a preservative and I actually kinda liked that taste as it had bit of a bite to it. It is now rather sickly sweet but the dosage is so small I don't really care and I can appreciate why some people would not want alcohol in it even though the amounts were minute. So bottom line is the product works and odds are you don't need it. Get a blood test to check your B12 levels first!

Product is perfectly fine - But I noticed no beneficial changes in my body
To be fair - I have tried a LOT of B12 supplements over the years. I am 80% vegan, so the doctor said it wouldn’t hurt to take B12. I have never noticed any significant difference in energy levels or spunk from any of the high end supps I’ve tried. This is another to add to the list. Excellent packaging, easy to use dropper dispenser. I was very apprehensive about the smell at first, because it smells exactly like cough syrup, which I can barely choke down when I’m sick. I hate the smell/taste of alcohol in most things, so I was quite worried I wouldn’t be able to actually use these drops. However, the taste is way sweeter and less alcohol-y than cough syrup! I honestly had no issue placing this liquid under my tongue and holding it there. Flavor was actually quite pleasant to me. Downside = I noticed absolutely no increase in energy or mental clarity or life ambitions, etc. I finished the whole bottle before writing this review to give it some time, and I’m sad that my world didn’t change dramatically like other reviewers’ have. Also, this item tended to ‘upset’ my delicate stomach. I had no pain or anything of that nature, but things became looser, if you catch my drift. Uppity. The label doesn’t clarify what sweetener they use (If I remember correctly, I’m not at home atm to check) and it just says “Natural Flavoring”, but I suspect it’s the sweetener that doesn’t agree with my fragile disposition. Sorbitol? Maltitol? Anything that ends in “ol” wreaks havoc on me, so... Yeah. Maybe it’s stevia? I don’t know. If your tummy can swing it, and if high dosage B12 supplements are what you’re in the market for, then this is for you! Tastes sweet and fruity, easy application, bypasses the intestinal tract. :)

Best B12 on the market! Period.
Before I get into the product itself, let me just mention that the seller is awesome. I had an issue with the label not showing the expiry date and reached out for support. They replied within hours and informed me that they verified it was good until 2025 but to reassure me, sent out a brand new one, no questions asked. This was a very kind gesture and makes me feel comfortable buying from this seller again! In terms of the B12 itself, this is an excellent product. I have now taken it daily for about a month and have already noticed many positive effects. For starters, my mental clarity and overall wellbeing has increased tenfold. I also require far less coffee (if any at all) to get my day going. To say this supplement has improved my quality of life is an understatement. The dropper is the best one I have used, never leaks or spills drops while putting toward mouth.. an underrated aspect of many similar products. Furthermore, the flavour I personally find delicious and the potency allows me to get more bang for my buck. I will be buying this product for many years to come, the return on investment is incalculable.

Amélioration marquée
J'aime ce produit, il fait une énorme différence pour mes pieds. J'étais au point où tout les soirs mes pieds engourdissaient ou brûlait. Maintenant ce n'est qu'à l'occasion si je n'ai pas assez marcher. Merci au vendeur

Dropper bulb just not quite big enough
Good flavour, easy to use, simple ingredients but the downside is the dropper itself. When it is empty and you squeeze it to fill it up, it never fills to the 1mL line. The dropper bulb on top itself isn't big enough and no matter how hard we try to squeeze it or how far down into the liquid we get the glass part, it never fills anymore than to .75mL.

A must have staple for those with a B-12 Deficiency
Such a great way to up your B-12 take. I’m vegan and this has helped me out immensely. My bloodwork looks great now thanks to this supplementation ! It doesn’t taste bad either! My younger siblings actually loves the taste

It’s a healthy product
