B12 Extreme Energy + Stacker 2 10,000% RDA - (24) Four Count Blister Pks by Stacker

Great energy booster in the afternoon or overnight work. Packs are convenient.

These work really well, no up and down no jitters. Helps with brain fog.

For me, this B12 Extreme Energy capsule has a smoother and longer uptake than the liquid, bottled version. It also seems to last longer and have a longer "tail" when tapering off. Whether its the caffeine or the B12, it does the trick for me. It doesn't give me a "high" but rather seems to change my attitude and energy from cloudy to sunny, or from half-empty to half-full. It feels like an attitude adjuster rather than just an energy boost. I'm not a doctor and have no opinion or knowledge about how or why it works. But for me, it is a game changer!

These worked well.

Perfect for the afternoon energy slump without the jitters like some of the other energy supplements

T works with no side effects. Easy to swallow.

I looked for a great B12 that could kick upp my super low energy daily and theese did the job in the beginning , later on they where OK. So i was ordering them for few months and took them daily until recently when i got cold severly and i STOOPED taking theese pills for a week , i noticed that the three first days i was sooo nausaues condtantly for 3 days non stop i couldnt move , sit , eat or lay down too long time i felt like i was SEA SICK‼️I realized that i was detoxing from whatever was in theese pills that was so disgusting … i cryed for help and couldnt understand that it was caused by theese pills until i saw my husband beeing sick with the cold in the same exact days but he was Not seasick for 3 days as me 😳 so THIS A WARNING FROM ME!From now on i will buy moore expensive , reliable B12’s to feel great.

they work great for me
