A vital co-enzyme that helps repair damage and prevent aging can now be bought over the counter – is NAD+ the Longevity wonder drug people are hoping for?
Nicotinamide adenine dinucleotide is a chemical that enzymes need in order to function – a coenzyme – and it performs a crucial role in respiration, the process by which cells convert glucose and oxygen into energy. Like a taxi that ferries passengers from place to place, NAD+ collects an electron from a molecule, becoming NADH, and drops it to another molecule and in doing so reverts to NAD+.
TRU NIAGEN has developed a unique form of vitamin B3 clinically proven to safely increase levels of NAD.
Longevity.Technology: A vitamin that promotes healing and halts aging on a cellular level would revolutionise medicine, being easily administered and available everywhere. A once-a-day solution to old age? Sign us up!
The TRL score for this Longevity.Technology domain is currently set at: ‘Technology refined and ready for initial human trials.’
The TRL score for the technology addressed in this article is: “Late proof of concept demonstrated in real-life conditions.”
Moving electrons from place to places ensures the enzymes trigger small and numerous chemical reactions that lead to growth, movement, repair and all bodily functions. Without NAD+ our mitochondria, the powerhouses of our cells, cannot make energy and the cells die. Researchers in Switzerland proved this with an experiment that inhibited it and caused total cell death .
As well as its vital role in energy production, NAD+ also plays a key part in ensuring that proteins are folded and rippled into exactly the right shape to perform their function . Proteins fold in special ways to ensure they are in the most energetically favourable and compact shape .
So, NAD+ is a vital chemical, but what is its specific Longevity function?
Mitochondria use NAD+ to repair themselves if they are damaged or put under stress and a lack of it means they cannot; the associated decline in both the number of mitochondria and their quality has been linked to aging and age-related diseases . NAD+ is also used by sirtuins, incredibly important proteins that regulate cellular health and maintain the length of our telomeres, ticking biological clocks that shorten every time a cell replicates itself. Once the Longevity-linked telomeres are too short for cell division, the cell enters senescence and can produce damaging chemicals that induce aging. Sirtuins can only function in the presence of NAD+ .
NAD+ also protects cells from stress – damage that can cause senescence and aging. Researchers found that cells given an NAD+ boost were more stress-resistant and less likely to die . NAD+ is also used in DNA repair, bringing a negative charge to damaged strands and aiding repair. This process uses up NAD+ and research has shown that increased quantities of NAD+ increase lifespan by facilitating increased DNA repair .
There are numerous benefits to having good levels of NAD+, but researchers have found that NAD+ declines by up to 50% between the ages of 40 and 60 . The good news is that Nicotinamide riboside has been found to increase levels of NAD+ and is now available as a dietary supplement. TRU NIAGEN, part of ChromaDex, has developed NIAGEN, a “unique form of vitamin B3 clinically proven to safely increase one’s levels of NAD,” .
TRU NIAGEN was featured at the American Academy of Anti-Aging Medicine World Congress in December 2018  and activating sirtuins to slow or halt aging has proved a hot prospect before – GlaxoSmithKline bought Sirtris Pharmaceuticals for $720million in 2008 . The US supplement market alone is projected to reach $52.5billion next year , so Longevity over the counter will of course be a real winner.
