If you already take a multivitamin, it's a fair question: why pay more for the same vitamins through a vein?
The bioavailability argument, honestly stated
Anything you swallow has to survive digestion and be absorbed through the gut before it reaches your bloodstream, and that process isn't perfectly efficient — some portion of any oral vitamin or mineral is lost along the way, and absorption can be reduced further by an upset stomach, certain medications or gut conditions. An IV infusion bypasses that step entirely, delivering the full dose directly into circulation. That's the real mechanism behind the claim, not marketing shorthand.
Where that actually matters
It matters most when you need a larger dose delivered quickly — rehydrating after a hangover or a day in the Dubai heat, for example, or getting a meaningful dose of an antioxidant like glutathione into circulation in one sitting rather than a slow trickle over weeks of tablets. It also matters if you simply can't tolerate oral intake well, whether that's nausea, a sensitive stomach, or difficulty keeping food and supplements down.
Where oral is genuinely fine
For routine, ongoing nutritional support — a daily multivitamin, vitamin D in a sun-light winter, iron for a mild deficiency — a well-chosen oral supplement, taken consistently, does the job perfectly well for most people. IV therapy isn't designed to replace a reasonable diet and a sensible supplement routine; it's a faster, more direct option for specific moments, not a permanent substitute for either.
The honest takeaway
Neither option is universally "better." If you're after a quick reset, acute rehydration or a bigger one-off dose, IV therapy does something oral supplements structurally can't. If you're after steady, long-term nutritional support, a consistent oral routine is usually the simpler and cheaper answer. We're happy to talk through which fits what you're actually trying to achieve.
