IV therapy - short for intravenous therapy - is a way of delivering fluids, vitamins and minerals directly into a vein through a small drip. It is the same trusted method used in hospitals and ambulances every day, brought to you in a comfortable wellness setting.

Straight into your bloodstream

When you take a vitamin tablet or drink a sports drink, it has to pass through your digestive system first. Only a portion of what you swallow is actually absorbed, and that amount varies from person to person. An IV drip skips the gut entirely, so the fluids and nutrients are available to your body right away.

What is usually in a drip?

Most wellness drips start with sterile IV fluids - the same balanced fluids used for rehydration in clinical settings. From there, different blends add a supporting mix of vitamins and minerals depending on what the drip is designed to support. Providers differ in exactly what they include - at VitalLine Infusions we share the full contents of each blend when you enquire, and your clinician walks you through every component at your consultation.

  • Hydrating fluids and electrolytes
  • A supporting blend of vitamins and minerals, matched to what the drip is designed for
  • Nothing is given without screening, a consultation and your consent

Is it right for everyone?

Our wellness infusions are designed to support hydration and general wellbeing - they are not a treatment for any medical condition. Everyone completes a short health screening that a clinician reviews before any infusion goes ahead, because some people and some circumstances are not suited to IV therapy.
