We all know that maintaining our health and energy levels as we get older is not easy. But many people aren’t aware that part of the blame lies squarely with some of the tiniest foundational molecules in your cells – and once you take care of these, it allows the rest of your body to follow suit. One such molecule that’s crucial to our health is called nicotinamide adenine dinucleotide – or NAD+.
Scientists have been aware of NAD+ since it was first discovered back in 1906, but only more recently has its importance to health come to the forefront due to its central role in biological functions.
The human body is miraculous and composed of trillions of cells, with each cell having its own purpose. NAD+ is a vital molecule that all cells are reliant on to generate the energy they need to function properly. NAD+ is involved in hundreds of reactions within the cell and importantly, provides the mitochondria with fuel to turn nutrients into energy.
All of the cells in the body, whether they be heart, liver, muscle or brain cells, are dependent on NAD+ to help support energy levels, cellular repair and regeneration.
However, NAD+ levels are known to decline with age, so it’s important to keep an eye on them. Between the ages of 40 and 60 NAD+ levels can decline by up to 50 per cent, which leaves the mitochondria to compete for a shrinking supply of this vital resource.(1) Without sufficient NAD+, mitochondria are unable to optimally power our cells, making the body vulnerable to cellular damage.
Along with ageing, lifestyle stressors like overeating or excessive drinking are also things known to cause a decline in NAD+. Yet despite its importance, it’s not entirely understood why NAD+ declines as you age, so scientists are urgently investigating ways to maintain your NAD+ stores.
Making sure you have an adequate intake of NAD+ precursor nutrients is vital to making sure that your body’s needs are being met through your diet. But this becomes slightly difficult when you’re unable to easily obtain some nutrients through food at the quantities required to have a beneficial impact.
One such nutrient scientifically proven to boost NAD+ levels is a novel form of vitamin B3 called nicotinamide riboside (NR).
It was in 2004 that scientists discovered that NR was a unique and overlooked form of vitamin B3 and that it was a natural precursor to NAD+. This means that once ingested it’s taken up and converted to NAD+ in our cells, thus supporting cellular energy, repair and regeneration.
If you’re wondering why you can’t just take a pill of NAD+ and be done with it, it’s because NAD+ is not bioavailable. This means that you can’t take it orally as it won’t survive the digestion process intact.
However, don’t despair – NR has recently become available to Australian consumers as a patented dietary supplement called Tru Niagen®.
A daily intake of 300mg of Tru Niagen® boosts NAD+ levels which supports energy levels, cellular repair and general health and wellbeing.
So take a moment to consider “the little things” that are powering busily away inside your body at a molecular level, and take steps today to see that you are making the most of every advantage to support your inner health and wellbeing.
