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

Great Product!
I felt the difference from day 1. It supports mood, and provides energy. One does feel better after taking it. Very easy to swallow. Thank you!

If you even *think* you may be low in b12 then get this
Being low in b12 can be very scary. I personally have had various deficiencies over the years and b12 deficiency has the worst symptoms. I don't want to go into too much detail but anyone experiencing mental issues should be supplementing this and don't be afraid to take a "therapeutic" dose. When I got these I immediately started taking 3 per day. I took a few days break bc I felt better and let me tell you not to do that. Be consistent. after about 10 days my brain begin to change and reality seemed more normal. Of course I am putting my family and friends on this. It's' too important to let anyone be deficient especially in these stressful times. Also note that stress depletes nutrients from your system as well as any illness. also, your liver requires b12 to help it not accumulate fat and to detox. Take care of yourselves.
