NAD+
01 Summary
A coenzyme found in every cell, essential for turning food into energy and for repairing DNA. Levels fall with age, which is why it has become a centrepiece of longevity routines.
02 How it works
NAD+ shuttles electrons in the reactions that make cellular energy, and it is the fuel for sirtuins and PARPs — enzymes involved in DNA repair and cellular maintenance. The idea behind supplementing is to top up levels that decline with age.
03 Common uses
04 Run profile
Started low and built up over a couple of months. Taken two or three times a week, with the days spread out, in twelve-week blocks.

06 What to watch for
A flush — warmth, redness, a niacin-like feeling — during and just after the injection is the big one, and push speed is the main driver: going slower helps most. Nausea, headache and soreness also come up. Severe or prolonged flushing, chest tightness or persistent vomiting need attention.
07 Evidence & status
Not approved (injectable)NAD+ biology is well established; evidence that injected NAD+ improves health outcomes in people is still early.
Not FDA-approved as an injectable drug. NAD+ precursors (NMN, NR) are sold as supplements.
08 FAQ
Why does it make me flush?
It is a common, niacin-type reaction, mostly driven by how fast it goes in. Slower is better.
Is it the same as NMN or NR?
Those are precursors the body converts into NAD+. Injecting NAD+ skips that step.
When will I feel it?
Some people notice energy changes within days; others feel little. It is very individual.
