"Intravenous (IV) vitamin therapy (also known as intravenous micronutrient therapy and hydration therapy) is a way to give high concentrations of vitamins and minerals directly into the bloodstream, allowing rapid absorption of higher doses of the vitamins and minerals than if the person got them through food or supplements."
"The infusions typically take 20 minutes to an hour, depending on the volume of the cocktail and the size of the person's veins."

"During intravenous (IV) vitamin therapy, a cocktail of vitamins, including vitamin C, B vitamins, magnesium, calcium, and sometimes glutathione, are delivered to your bloodstream by inserting an IV line into your vein. Your cells require nutrients to operate efficiently. But factors like chronic illness, prolonged stress, and inflammation can deplete your cells of the vital nutrients you need to get well."

"It is a way to replenish depleted vitamins and minerals even when their absorption is impaired. Often patients feel better right away. The infusions are easy to administer and completely safe."

"Intravenous (IV) vitamin therapy, or vitamin drips, promise to help.
Some claim they can even benefit serious conditions like cancer, Parkinson's disease, the eye condition macular degeneration, the pain of fibromyalgia and depression.
Celebrities have promoted them on social media. The demand has led to alternative therapy lounges popping up around the world, including in Australia. Patients can kick back in comfy leather chairs while they're hooked up to IVs in the infusion lounge, watch Netflix and have some tea.
But do they work?"
