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.

Good supplements from seemingly good company.
This was well received by my son, he said it helps his neuropathy and blood sugar issues, plus feeling better.

Works well for diabetic kitty and at a lower price than veterinary brand
This is my second purchase of this item. My diabetic cat benefits from a daily dose of B12 (Methylcobalamin) to prevent neuropathy in her hind legs. I was using the brand recommended by her vet, but it's very expensive and she hated the taste...would spit it out or not finish taking it. I found this and tried it. I mix it with Churu squeeze up treats and she scarfs it down. Works as well as the vet-recommended brand name, and it's much less expensive.

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.
