There have been major breakthroughs on a worldwide scale when it comes to understanding how we age and steps, serious steps, we can take to not only slow it down but to all appearances, reverse the process. Over history, seekers after a Fountain of Youth came, literally and figuratively, to dead ends, but Ponce de Leon had no internet down in Florida back then. I do, and after a few clicks, I am reading solid research from universities around the world: Japan, Israel, and the U.S.
The “Big Boys” of scientific publications, “Nature”, “Science”, and “Aging Cell” accept only peer-reviewed scientific research, quality over hype. If you’re put off by too much scientific jargon, graphs and tables, the well-known Life Extension Foundation, writes very accessible prose although admittedly a little prone to hyperbole.
The big news of the past couple of years has been a substance produced in our own bodies, nicotinamide adenine dinucleotide, NAD+ for short. It is classified as a ’cofactor’ meaning that it helps all the parts of your metabolism run efficiently. Imagine your metabolism as billions of gears running constantly, 24/7, from your conception to your final breath. NAD+ lubricates everything. Without NAD+ you’d be dead, instantly.
Scientists have spent decades trying to figure exactly how we age, why some people are “old before their time” and die quite young, while others are mentally and physically fit and nearing 100, even enjoying a daily cigar and a martini. The current thinking is that over the years, we age because we’re exposed to a variety of toxic substances (“free radicals” is one, for example) that slowly but relentlessly damage our cells. When we’re young, we’ve got plenty of a very specific second substance, NAD+, to do damage control. Unfortunately, over the passage of time, our bodies simply don’t make the amount of NAD+ capable of keeping up with the damage to important things, like our DNA, like our mitochondria. At 50, you have only half the NAD+ you enjoyed as a callow youth. At 80, you’re lucky if you have 5% left.
Here’s what NAD+ is doing for your body in terms of “anti-aging”. It’s a little complicated, but not impossible.
- NAD+ is needed to maximize the efficiency of a certain protein called sirtuin that contributes to your longevity by maintaining the length of your telomeres. These are stretches of DNA on the ends of your chromosomes. Telomere shortening is the key marker that shows cellular aging and when telomeres reach a critically short length, cell renewal stops, leading to accelerated aging and cell death. NAD+ appears to extend telomere length.
- On a cellular level, whenever DNA is damaged, it activates PARP-1, an enzyme necessary for prompt and efficient DNA repair. PARP-1 requires large amounts of NAD+ to function, and as you age, because of declining NAD+, your ability to repair DNA declines. Your immune system falters, subjecting you to infection and cancers, and you accumulate waste products, like your arteries harden or there’s plaque in your brain.
- NAD+ regulates your otherwise aging immune system, allowing it to steer a midcourse between overactivity (as ‘autoimmune’ disease) or underactivity (susceptibility to infection and cancer).
- NAD+ maximizes how we get energy from food. I’m sure you noticed that as you got older, your energy level declined. Watching a group of children at play and you ask, “Where do they get all that energy?”. Basically, they have much more NAD+ than their parents and can extract a lot of energy from several bites of birthday cake. NAD+ promotes energy extraction and increases the capacity of your cells to work efficiently.
- NAD+ was recently discovered to not only restore nervous system neurotransmitters but act as a neurotransmitter itself.
Raising your NAD+
The fastest and most efficient way to raise your NAD+ is to begin a series of intravenous treatments (IVs), usually a total of 5 to 7, over a period of 10 days, then following this by a combination of maintenance IVs (one a month) and oral nutritional supplements. If you’re basically in good health, the regular strength NAD+ is fine. If, however, you have a chronic health issue of virtually any kind, using the higher strength NAD+ is probably a better choice. IV NAD+ is now worldwide and you can find one if you live near any urban area.
A less time-consuming way to boost your NAD+ is through NAD+ injections. As you won’t have to sit 1-3 hours for an infusion, injections take about 15 min and are recommended once or twice a week for the first 4-6 weeks as well.
Lifestyle changes can boost your NAD+ as well. The process will be slower and the results less dramatic than intravenous infusions but considering the benefits of healthy NAD+ levels, you might as well get started now.
The following have been shown to raise NAD+:
- Regular exercise;
- Following a low carb keto diet. Being in ketosis, where your body uses fat instead of glucose for energy, increases your NAD+;
- Practice intermittent fasting;
- Foods high in NAD+ are fish (especially tuna, salmon and sardines), mushrooms (especially crimini mushrooms);
- Supplement with an NAD+ precursor (a/k/a building block). This is a variation of Vitamin B3 called nicotinamide riboside. FYI, NAD+ isn’t available as a supplement because the delicate molecule is destroyed during digestion.
You might have already figured that NAD+ infusions are offered at WholeHealth Chicago. We’ve priced our NAD+ series competitively and two warnings: these are not covered by your insurance (but you knew that already, I’m sure) and you need to allow three hours for each infusion, so bring your phone, your PC, a good book or just plan a long meditation.
Be well,
