A Systems Approach To NAD+ Restoration

NAD+ is now known to be a very important molecule for cellular health and to support healthy aging, but NAD+ levels are known to decline with age.

Preclinical studies in animals have shown the great benefits of restoring NAD+ levels including:

• Improved cellular energy levels and supporting mitochondrial health
• Supporting cognitive function
• Supporting cardiovascular function
• Supporting metabolic health
• Supporting muscle strength

Following the positive preclinical studies focus has now shifted to human clinical trials. These trials take a single target approach using precursor compounds such as NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) – raw materials used by the cell to make NAD+.

A wealth of data now shows that this isn’t the best approach to boosting NAD+ levels as the cause of NAD+ decline is more complex than previously thought.

Overall, age related NAD+ decline occurs due to multiple issues:

• Decreased production and recycling of NAD+ by cells
• Increased consumption and wastage of the limited NAD+ by hyperactivated consumers
• Leading to a deficit of NAD+ for key cellular processes that depend on it

NR and NMN supplementation do not address any of these underlying root causes of NAD+ decline.

Evidence suggests that while precursor supplements may cause a temporary increase in cellular NAD+, once this NAD+ is broken down and used by the hyperactivated NAD+ consumers it is effectively wasted because the cell is unable to recycle the breakdown products back into fresh NAD+.

This can lead to further issues as the cell has to compensate for this sudden boost in NAD+ breakdown products by methylating the waste products so they can be excreted from the cell. Leaving a shortage of methyl donors available for other vital cellular reactions.

Dr Conlon proposes evidence for an alternative and more sustainable strategy to boost NAD+ by using a multi-target approach which addresses the root causes of NAD+ decline.

A multitargeted approach involves simultaneously:

• Providing NAD+ precursors to the cell
• Inhibiting hyperactivated NAD+ consumers such as CD38
• Activating key NAD+ salvage and recycling enzymes such as NAMPT
• Inhibiting NNMT to prevent excessive methylation and promote NAD+ recycling

The use of a multi-targeted approach could provide synergistic increases in NAD+ levels by addressing the multiple root causes of NAD+ decline.

This could provide greater levels of NAD+ restoration with greater measurable health benefits and reduce potential unwanted effects associated with high doses of NAD+ precursors.

 

That is exactly why Dr Conlon and her team spent years studying the best combination of ingredients which target the key areas of the NAD+ production network described. This research led to the development of Nuchido TIME+, a next generation NAD+ supplement which goes beyond just providing cells with precursors ingredients. This approach was supported by the results of a randomised, double-blinded, placebo-controlled crossover clinical trial.
