Something I explain to every new client as their nurse: the supplement you’re taking might be doing almost nothing.
Here’s why:
When you swallow a vitamin, it travels through your digestive system and liver before ever reaching your blood. This is called the first-pass effect — and it can cut absorption to as low as 10–20% for certain nutrients.
IV therapy delivers directly to your bloodstream. Zero first-pass. 100% bioavailability. It’s not that supplements are bad — it’s that your body has real limits on what it can absorb orally. IV therapy fills the gap.
