Easy to take with clean ingredients
I have been taking this B12 supplement consistently, and it has been easy to incorporate into my routine. The tablets are simple to take, and I appreciate the vegan, non-GMO formulation and clear labeling. The bottle lasts a long time, which makes it a good value. While individual results can vary, this feels like a well made, straightforward option if you are looking for a fully active B12 supplement.

My favorite vitamin brand
I love this brand. I’ve been taking these specific vitamins for about 2 years after discovering a deficiency. They seem to be working because my blood work is coming back in normal al range! They are super small and go down easy. I haven’t had any issues with any of their vitamins and my stomach. Which is a miracle because I have IBS. If you are in the fence about this brand just get some. You won’t be sorry

Very good
This is really good B12 supplement. I took it for 4 weeks and my B-12 level went from a level of 122 up to 540, which is excellent. I take on empty stomach with water. Absorbs quite nicely. I will be a long time customer with this product.
