High-Quality B12 That Truly Makes a Difference
Thorne Vitamin B12 as Methylcobalamin is one of the best supplements I’ve used. The methylcobalamin form is easy to absorb and doesn’t upset my stomach like some other B12 products I’ve tried. I’ve noticed a real improvement in my energy levels and overall sense of well-being since I started taking it. The capsule is easy to swallow, and the quality feels premium — exactly what I expect from a reputable brand like Thorne. I also appreciate that it’s cleanly formulated without unnecessary fillers or additives. For anyone looking to support energy, cognitive health, or overall B-vitamin balance, this B12 supplement is a fantastic choice. Excellent efficacy and great value for what you get. Highly recommended!

The quality feels premium, and I appreciate that Thorne is a trusted brand with clean, well-absorbed formulations. It’s gentle on my stomach and easy to incorporate into my wellness routine. If you’re looking for a reliable B12 supplement that supports energy, mood, and overall well-being, this one is fantastic. Highly recommend! 💊✨

Possibly a reputable vitamin product that works.
The unregulated vitamin industry makes it hard to choose reliable supplements for sure. So I find this Thorne company, through my minor research and how I feel after using, seems to have a better quality product. For example, this Vitamin B12 that I am using for about two months may be why I am sleeping better and generally feeling noticeably good and improved. I also use their testosterone which deserves the same good recognition as I stated above. I am a 74 year old man trying to outsmart getting old.

The real deal. Highly recommend
This company is the best I've ever used. The pills are easy to swallow and the b12 content is all there so that, for the first time ever, I actually feel a substantial effect about a half hour after taking which lasts many hours. Quality all the way. Highly recommend.

Nice multivitamins
Tastes like a normal multivitimin, smells like one also. Size of the pill is about the average size of most other pills. Other than that, I took them as directed. Didn't notice any crazy differences tbh, just felt healthier knowing that I was supplementing like I was supposed to haha

Great quality.
This brand is amazing! I’ve made it through more than half this bottle and the health benefits have been huge!! I don’t have any issues getting these down or with having upset tummy issues. I’ve not had any adverse side effects at all! I will be continuing to buy these because they have worked so well for me!!

It came with the inside seal slightly opened and the plastic wrapping was easy to take the lid on and off without opened the plastic so honestly I am suspicious if these have been tampered with and I can’t seem to be able to return them
