How to start

  • Your NAD+ 4u pen kit consists of everything you need to self-administer injections. This typically results in high bioavailability, ensuring that a greater amount of NAD+ 4u is directly available to the body’s cells. By bypassing the digestive tract, they avoid the first-pass metabolism by the liver.

  • We suggest a monthly dosage of 1 gram, divided and administered every other day. With the supply of pure, active NAD+ 4u and included pen injection equipment, you can easily self-administer the treatment, empowering you to optimise your health and vitality on your own terms.

  • For initial usage, we propose administering the NAD+ 4u solution on three consecutive days, followed by alternate-day doses thereafter. With 16 doses per vial, our kit furnishes approximately 4 weeks’ worth of NAD+ 4u supplementation.

  • We maintain the recommendation of an initial loading dose of 250-1000mg via an IV, for discernible effects, which is administered at one of our Body Brilliant clinics.
