NAD+ is the latest molecule everyone wants to buy. You can quite easily walk into an IV clinic and get it through a drip, via patches that claim to feed it through the skin, other injectable forms, and a fast-growing shelf of precursor supplements sold on the promise of more energy, slower ageing, and improved neurological function. The enthusiasm is not misplaced. NAD+ is one of the most important molecules in human metabolism, and the science behind that claim is genuine. The order in which people reach for it is where the trouble starts.
Inside the mitochondrion, NAD+ is not where the work begins. It sits near the end of a long chain of dependent reactions, and every link ahead of it requires cofactors that have to be in place before the molecule can be built, recycled, or spent. If one delivers NAD+ into a cell whose upstream machinery is depleted, most of it will be wasted. The real deficiency sits upstream, in the cofactors and conditions that allow the cell to build and utilize NAD+.
None of this makes NAD+ less essential. If anything, it raises the stakes on understanding the molecule properly: what it does, why its levels fall with age and illness, and what genuinely restores them.
What follows in the article below covers:
What NAD+ actually is
The two forms of NAD, and why the distinction matters
The role NAD+ plays in health and disease
Why increasing levels of NAD+ is important
What sirtuins are and how they require NAD+
The role sirtuins and NAD+ play in vascular aging
Health conditions that benefit from increasing NAD+
The three ways the body produces NAD+
Natural ways to increase NAD+ levels in the body
If you have paid for NAD+ by drip, patch, or capsule and felt far less than the promise implied, the variable that nobody is measuring sits one step upstream of the molecule you were sold.
