Great Product
I love these. I’ve had a gastric bypass and my body doesn’t absorb things easily. The dissolving pills are absorbed quicker. The taste isn’t bad either. They are also very reasonable.

Good tasting, fast acting
They have a lovely flavor, dissolve very quickly, and have a positive effect on my energy level. I’m sure I will purchase these again.

Taste Great & Bloodwork Shows It Works!
I have been using this product since 2023 and couldn’t find it anymore at my original store. These are great and taste really good. I take these due to Metformin can deplete Vitamin B-12.

Pleased
Blood test said I was low on B12. So, I bought this product, because it had some good reviews. It's also chewable, so it's easy to take. This is a good product. I'm on my 2nd bottle. I love the taste. I hate taking pills of any kind. So this is a joy to take. It does pick up the energy. I will continue as the results continue. Have to get lab work done in a couple of months. We'll see what takes place. I believe it will good. I love this product because it causes the small capillaries in the toes and fingers to receive the blood they need. If I don't have this on hand, my feet and hands start to get numb. It feels good to know I can take this instead of taking something that has way too many side effects. I only take otc. I am 67 and I only take Bayer Aspirin once a week and Walgreens Antiacids once a week. My doctor said that I was the best patient she has, because everyone else takes at least 10 pills a couple times a day. I value my health and I watch what goes into my body. Make up your own mind concerning this vitamin, but I'm sold on them

Works Great and Tastes Good
I’ve been using these Natrol B12 fast dissolve tablets for a few weeks now and I’ve definitely noticed a boost in my energy and focus throughout the day. They dissolve quickly under the tongue with no need for water, which is super convenient for busy mornings. The taste is pleasant—kind of like a mild berry flavor—and not chalky like some others I’ve tried. The only reason I’m giving 4 stars instead of 5 is because the bottle doesn’t last very long if you're taking them daily. It would be nice if there were a higher-count option for better value.Overall, it’s a solid supplement that does what it claims. If you’re looking for a quick and easy way to get your B12 in, this is a great pick!

Great way to get your B 12
My doctor recommended that I start taking B 12 and these work great. You can just place them on your tongue and the pill begins to dissolve. These were safely packaged when I received them. It made me feel good that they were not tampered with. They taste good too. Good price as well.

Great brand
This works extremely good and extremely fast and it stays in your system. I took one a week prior to blood work and let’s just say it lasted the whole week. They taste extremely good too if you’re gonna get these and you think that you’re gonna be able to take them every day, don’t get such a high dosage like me get a smaller dosage, but it’s a really good brand.

These really work
Last year I had tests done due to feeling awful, tired, dragging thru the days etc It was found my B12 was extremely low and I had 3 months of shots and began these Natrol B12 tablets. My doctor warned that some people do not benefit from the tablets and must get monthly shots the rest of their life. After the three shots my B12 level shot up nicely but the test would be the 3 months of these tablets. I am happy to say my levels are even higher than after the shots. Obviously this product is the real thing plus it's easy to take, melts in your mouth and very tasty. If you need B12 supplements this is the one you want plus it's reasonably priced.

Despite the delay, it arrived within the deadline expected by the seller. Regarding the product (Vitamin B12) it has a mild strawberry taste and is quite pleasant on the palate. Easy to swallow and felt good to work or do any activity. A great product.
