Clean and effective B12 for energy and clarity

This is one of the best B12 supplements I’ve tried. Thorne’s methylcobalamin form is highly absorbable, and I can truly feel the difference in my energy levels and mental clarity. Within days of starting it, I noticed reduced fatigue and better focus throughout the day. It’s also great that Thorne avoids unnecessary additives — the formula feels very clean and gentle on the system. The 1 mg dose is just right for daily support, especially for vegetarians or those with absorption issues. A high-quality supplement from a brand I trust. I’ll definitely repurchase.

In my opinion and based on the scientific papers I’ve read, this is hands down the best form of B12. Packaging and shipping was stellar, as always. Capsules are small in physical size so no issues swallowing and such. Premium quality. I’ll definitely be getting my vitamins from here going forward.

Best B12 formula I’ve tried so far

I’ve tried several different brands, but this Thorne B12 formula is way better than the others I've used. You can really tell the quality is higher, and I love that the ingredient is Methylcobalamin, which is much easier for the body to actually use. The capsule size is nice and small, making it very easy to swallow daily. I also appreciate that it doesn't have unnecessary fillers like folic acid, which is a huge plus for me. It’s definitely worth switching to if you’re looking for something more effective

Great

I am giving B12 as a support supplement for leucovorine for my autistic san . Started 1 week ago, so it is early to say any positive sign, but Thorne is a trustable and clean brand even for a child. Happy with my order so far

B12 is a must!!!!

Thorne is a GREAT brand. The quality of their vitamins and sourcing is good. The vitamin size is small which is nice you don’t feel like you’re swallowing a gumball. This specific version of b12 metabolizes better in your body leading to better absorption and benefits. There is no taste.
