This is a normal response — there is no need to panic. Understanding the three reasons below, you'll see why your body "over-revvs" this way, and how to manage it simply.
1. Blood Vessels Suddenly "Unbound" — The Heart Forced to Race
When NAD+ enters the bloodstream quickly, a portion of it converts into a substance called adenosine. This acts like a flare, signaling blood vessels throughout the entire body to suddenly relax and dilate.
Once the vessels widen, blood pressure tends to drop. To keep you alive, your brain instantly sends the heart an urgent command: "The vessels are wider — pump faster!" Your heartbeat suddenly accelerates and pounds harder, and you feel a strong sensation of palpitations.
2. The Engine Suddenly "Overclocks"
The heart is the most energy-hungry organ in the body, an engine that never stops. The core function of NAD+ is to supply fuel to the "power plants" (mitochondria) inside your cells.
If the drip is too fast, fuel instantly floods the heart cells. The power plants suddenly go full throttle, churning out energy (ATP). This "acute burst" of energy breaks the rhythm the heart is accustomed to, making cardiac muscle cells unusually excitable — causing an irregular or fluttering heartbeat.
3. Chest Smooth Muscles "Cramp"
Beyond the heart itself, overly fast NAD+ delivery also stimulates the smooth muscles around the chest cavity and gastrointestinal tract, causing them to tighten and contract.
Often, what you feel as palpitations is actually a heavy, "breathless, tight" sensation in the chest — like a large stone pressing down on you. This discomfort makes you anxious, and anxiety in turn drives your heartbeat even faster.
The Simplest Solution
Simply slow the drip rate, or pause the IV for 2–3 minutes. Once your body burns off the excess fuel, the blood vessels return to normal, and the palpitations usually disappear completely within minutes.
