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!

Easy to Take and From a Brand I Trust
I’ve used Thorne supplements for years and have always been impressed with their quality. Like most vitamins, it’s difficult to know exactly what is making a difference day to day, but I appreciate the clean ingredients and the reputation behind the brand. This B12 is easy to take and has become part of my regular routine. A quality product from a company I trust.

A must for MTHFR sufferers
These have no added fillers that can upset my stomach like magnesium citrate or any other form of magnesium. You take three a day and having the MTHFRG mutation these are very important for my brain function and overall body. The price isn’t too bad.

Sooo small warning
I got a dental implant and the doctor placed the implant too far down pressing on my nerve. My face has been numb, but improving for over a month now. Thankfully it has improved and he recommended b12 with any nerve healing. Easy to take and no taste. My problem are the side effects. My tips of my fingers and bottoms of my feet hurt bad and burn as well as tingle. I found out this can be a side effect. Just fyi.

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
