Our NMN is highly potent and stabilized. It is the ultimate NAD+ boosting anti-ageing supplement that is entirely natural, will boost your energy and will provide numerous health-enhancing benefits. Our sublingual powder comes with a little scoop/spoon measuring 250mg per level scoop. Its rapid absorption properties increase bioavailability by avoiding the GI tract. We are unique in the UK and Europe as our NMN is stable under the most extreme heat conditions is 99% pure, free of heavy metals and toxins and is manufactured in a GMP facility according to USA standards. Our NMN has also been tested to ensure that it is endotoxin-free, which is a particular problem with most NMN, as reported by Dr. David Sinclair. Increased NAD+ levels stimulate energy metabolism, DNA repair and SIRTUIN activity (SIRTUINS are the longevity genes shown to be active during caloric restriction and life extension in many animal models.) *
