Wasn’t sealed properly
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

Easy to Add to My Daily Supplement Routine
I added THORNE Vitamin B12 1,000 mcg to my supplement routine because I wanted a straightforward B12 product from a brand I’m familiar with. I already take several supplements, so I appreciate products that don’t make my routine unnecessarily complicated.One of the things that caught my attention is that this uses methylcobalamin, an active form of vitamin B12. I also appreciate that it’s NSF Contents Certified, which gives me additional confidence when choosing a supplement.The capsules are easy for me to swallow, and I haven’t experienced any stomach discomfort from taking them. The 1,000 mcg amount also makes it simple because I know exactly how much B12 I’m getting in each capsule.I don’t expect a vitamin supplement to create some dramatic overnight change, and I haven’t been using it long enough to make claims about long-term results. For me, this is more about maintaining a consistent supplement routine and making sure I’m getting the nutrients I’m looking for.So far, I’m very happy with the quality, simple formulation, and convenience. If you’re specifically looking for methylcobalamin B12 and prefer a straightforward capsule instead of gummies or flavored supplements, this has been a good fit for me.
