They just upgraded the packaging, so the stickers are way easier to get off their backing. They stay on all night long. I have the most sensitive skin of anyone I’ve ever met, and they do not irritate my skin. I get a great nights sleep with minimal grogginess in the morning. And within an hour of putting it on I feel sleepy.This patch is a lifesaver.

I bought these when my doctor told me I needed to take iron everyday because I am deficit. About 6 years ago I had weight loss surgery and knew I would always need to take vitamins from then on out, but they didn't explain how finicky my stomach would be when it comes to taking oral medicine. Every vitamin I took would come back up.So far these patches are awesome! I have very sensitive skin, and react to almost everything. I've worn these for 3 days for 8 hours while working, under long sleeves and no reactions.Will update when I get blood work done again with their ability to make results go up.

Levels are currently 249.Also, taking B-12 well only give you additional energy if you're deficit. Don't expect to run a marathon the moment you put this on.

They didn’t work for me but they work for others. Good product

Good adhesion but leaves a small residue when removed. These do not come off until you are ready to remove them- that’s a plus! Absorption is excellent.

Multivitamins are way too big for me to swallow, and I’m not too fond of gummies. These are so easy – just remove from the film and slap it on. Stays on for longer than the recommended eight hours. Will definitely buy again:)

I have been using the patch for 2 weeks now. I haven't noticed significant changes to claim it works. I have felt at times that I am focused but not sure if it's a placebo effect that's making me think I'm more focused. I won't be buying it again though.

El parche es efectivo, solo se puede usar por 8 horas, se recomienda usar por la noche, pero aun no lo uso a esa hora

Got these patches after gastric bypass and my vitamin levels are holding strong! The patches don't stick as well as they should to me, but to be fair, I have trouble with most band-aids and medical tape not sticking as well. It may or may not be an issue for you, but for me, they don't always stay on for 8 hours.

I got the patch because I needed some extra collagen. Love the way they work.
