If you've been curious about IV therapy but aren't sure where to start, you're not alone. The idea of receiving nutrients through an IV line can feel clinical or intimidating at first — but for the vast majority of people, the experience is straightforward, comfortable, and surprisingly relaxing. This guide covers everything a first-time client needs to know, grounded in the clinical evidence behind why IV nutrient delivery works.
What Is IV Therapy, Exactly?
Intravenous (IV) therapy is the direct delivery of fluids, vitamins, minerals, and other nutrients into the bloodstream through a small catheter placed in a vein — most commonly in the forearm or hand. Because the nutrients bypass the digestive system entirely, they reach your cells at concentrations that oral supplementation simply cannot match. A 2025 review in Cureus summarized this advantage clearly: IV vitamin therapy "offers enhanced bioavailability, higher therapeutic dosages, and targeted nutrient replenishment, making it particularly effective for individuals with malabsorption issues and chronic illnesses."[1]
The concept was pioneered by Baltimore physician John Myers, MD, in the 1970s, whose formula — now known as the Myers' Cocktail — remains the most clinically documented IV therapy blend in the world. A landmark 2002 review by Alan Gaby, MD, documented its use across a wide range of conditions including fatigue, migraines, fibromyalgia, and immune dysfunction.[2]
What Happens During a Session
When you arrive for your first IV therapy session at Nectar Wellness, a licensed registered nurse will conduct a brief intake assessment to review your health history and confirm the right blend for your goals. A small catheter is then placed in a vein — a process that takes only a few seconds and is generally no more uncomfortable than a standard blood draw. From there, the IV line is connected and the infusion begins at a controlled, comfortable rate.
Most sessions run between 45 and 75 minutes depending on the blend. Many clients use the time to rest, read, or simply decompress. The setting at Nectar Wellness is designed for calm — not a clinical waiting room.
What the Research Shows About Common Blends
The most commonly requested first-time IV therapy is the Myers' Cocktail, which combines magnesium, calcium, B vitamins, and vitamin C. A 2009 placebo-controlled pilot study in the Journal of Alternative and Complementary Medicine found that patients receiving IV micronutrient therapy experienced "significantly improved tender points, pain, depression, and quality of life directly following treatment," with effects persisting four weeks after the final session.[3]
High-dose vitamin C is another popular option for immune support. A 2020 review in Nutrients found that intravenous vitamin C achieves plasma concentrations 30 to 70 times higher than the maximum achievable through oral supplementation — a difference that has meaningful implications for antioxidant activity and immune function.[4]
Who Is IV Therapy For?
IV therapy is appropriate for a wide range of healthy adults. The most common reasons people seek their first session include persistent fatigue, recovery from illness or intense physical activity, immune support during high-stress periods, and general wellness maintenance. It is not a replacement for medical treatment, and our nurses will always conduct a health screening to ensure suitability before any session begins.
People with certain medical conditions — including kidney disease, heart failure, or specific nutrient sensitivities — may not be appropriate candidates. This is why the intake assessment before every session is not a formality; it is a genuine clinical safeguard.
What to Expect After Your First Session
Most clients notice the effects of IV therapy within hours of their session. Common experiences include increased energy, improved mental clarity, and a general sense of physical ease. Some clients feel the effects most strongly the following morning. Minor bruising or tenderness at the insertion site is the most common side effect and typically resolves within a day or two.
For general wellness and maintenance, once or twice per month is the most common cadence. For acute recovery or immune support, weekly sessions may be recommended by your nurse.
