What IV Therapy Is, and What It Is Honestly For
An infusion places a small catheter in a vein and delivers sterile fluid, usually normal saline, plus whatever nutrients are added. Going straight into circulation skips the digestive tract, which is the real advantage: gut absorption is variable, and for some nutrients limited no matter how much you swallow.
Two things it does well. It rehydrates faster than drinking, which matters after illness, heat, or hard training. And it corrects a documented deficiency more directly than pills when the gut is the bottleneck, as with malabsorption or B12 deficiency related to intrinsic factor. In people who are neither deficient nor dehydrated, evidence for symptom benefit is limited, and much of what people feel comes from the fluid itself. That is why we pair infusions with lab testing, which tells you when to stop as well as when to continue.
One word about detox. Your liver and kidneys handle that continuously, and no infusion takes the job over or speeds it up. Where glutathione has a genuine role, it is as an antioxidant your body already makes. We describe ingredients by what they do, not by menu category.
