During a drip
NAD+ has to go in slowly. Most people feel it within the first few minutes if the drip runs too fast: a warm or pressure feeling in the chest, a tight or crampy stomach, a flushed face, a headache. This is the most common side effect and it is dose-rate related, which means the fix is simple: the nurse slows the drip and it fades. That is why NAD+ takes one to four hours instead of 45 minutes, and why the nurse stays the whole time.
During a shot
A shot is a smaller amount into the muscle or under the skin. The usual experience is a pinch, some soreness at the spot for a day, and sometimes a mild wave of the same warm feeling, shorter than with a drip.
The first day
Most people feel tired, or oddly calm, for the rest of the day. Some feel a lift the same evening. Drink water, eat normally, skip alcohol and a hard workout.
Days two to seven
This is where the reports are. People commonly describe clearer thinking, steadier energy, better sleep, and less craving for sugar or alcohol. We say "describe" on purpose: these are what clients tell us, and small studies, not large trials. Some people feel nothing much from a single session and more after a short series.
What is not normal
Chest pain that does not fade when the drip slows, trouble breathing, a rash or swelling, or a racing heart are reasons the nurse stops the drip and, if needed, you go to the ER. These are rare, and they are why NAD+ is never given without a licensed nurse present and a licensed provider's order.
Who should skip it or ask first
Pregnant or breastfeeding clients, anyone with a serious heart condition, and anyone on a long list of medications should talk to the provider on the video call first. That call is required before your first NAD+ drip and is overseen by our medical director.
Before you book
Eat something. Drink water. Clear the afternoon. A standard drip is 250, 500 or 1,000 mg; the provider picks with you. Shipped-to-you NAD+ injections come with plain instructions and a nurse for the first one if you want.
