The optimiser range works to improve your utilisation of the NAD+ in your body. Resveratrol, and Pterostilbene, contained within the NAD+ / AMPK Activator product, activate the Sirtuin proteins in your body responsible for your most vital biological processes. NMN & NAD+ is said to be the “fuel” for these Sirtuins! It is highly recommended to pair your NAD+ booster with either Resveratrol or Pterostilbene.
