Both B12 shots and IV drips deliver nutrients without relying on digestion. So which one should you choose?

It comes down to your goal and how much time you have.

Quick answer: Choose a B12 shot for a quick, targeted energy boost in about 5 minutes. Choose an IV drip when you also need hydration or a broader blend of vitamins and minerals. Many people use both.

How a B12 Shot Works

A small dose of B12 is injected into a muscle and absorbed into your bloodstream. It's fast, targeted and easy to fit into a busy day.

How an IV Drip Works

An IV delivers fluids, electrolytes, vitamins and minerals directly into a vein over 30–60 minutes.
