Good quality B12 supplement
I’ve been using this Vitamin B12 for about a month and it’s been working well for me. I take it every morning and feel more energized throughout the day. No side effects so far and great quality.

High quality Vitamin B-12 product
I use this product daily. It’s a quality b-12 product. It gives me energy and helps with mouth sores that I get due to a medication that I take.

Nice multivitamins
Tastes like a normal multivitimin, smells like one also. Size of the pill is about the average size of most other pills. Other than that, I took them as directed. Didn't notice any crazy differences tbh, just felt healthier knowing that I was supplementing like I was supposed to haha

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
