I’ve now talked to enough people about NAD+ to notice the same questions coming up repeatedly. Most of them are questions I had myself before starting. Here’s what I wish someone had told me upfront.
It Takes Longer Than You Think to Notice Anything
The first week, possibly the second week, you may feel nothing. NAD+ is not a stimulant. It doesn’t produce an immediate effect you can feel the way caffeine does. It works at the cellular level, restoring a resource that depleted gradually over years.
Most people start noticing changes somewhere between week two and week four. The changes are subtle at first. Better afternoon energy, slightly faster workout recovery, a bit less mental drift. If you’re expecting a dramatic transformation by day three, you’ll quit before it works.
The Side Effects Are Usually Mild and Temporary
Some people experience mild flushing, nausea, or fatigue in the first days. This tends to resolve quickly. It’s similar to the GLP-1 adjustment period in that your body is adapting to something new.
Going in knowing this prevents the “something’s wrong” spiral that can happen when you feel slightly off in week one.
It Works Best Alongside the Basics
NAD+ is not a substitute for sleep, movement, or food quality. I noticed the clearest effects when my fundamentals were already in decent shape. If you’re sleeping 5 hours and eating poorly, NAD+ will have less to work with.
Think of it as raising the ceiling on what’s possible when the foundation is reasonably solid. Not as a patch for a foundation that isn’t there.
The Telehealth Process Is Simpler Than You’d Expect
I assumed getting a prescription for NAD+ injections would involve multiple appointments and a lot of convincing. Through GobyMeds it was an intake form, a provider consultation, and a prescription. Straightforward.

You Don’t Have to Choose Between NAD+ and Other Therapies
A lot of people approach this as either/or. Either GLP-1 or NAD+. Either supplements or prescriptions. The more useful frame is what combination addresses what you’re actually experiencing. Most people who’ve gotten the best results are combining approaches thoughtfully rather than betting everything on one thing.
