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!

Pricey
The vitamins work well for helping me maintain my B12 levels. The capsules are a little larger than other b12 supplements, but I have no problem swallowing them. There is no taste and doesn't turn your mouth pink like other types. The biggest con is the price.

Thorne = Quality (Highly Recommend)
I didn’t know there so many differences in the quality of vitamins until I got sick 5 years ago and started doing research so I could heal my body as much as possible so I did not need medicine. My boss told me about Thorne, then started researching and using and the quality is absolutely there. I ONLY buy Thorne now for all me and my husbands needs. I encourage my adult children now as well when are needing any supplement, Def recommend!!!

Wasn’t sealed properly
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
