You are exhausted all day but wired the moment your head hits the pillow. The problem is rarely about willpower or screen time. It is usually biochemical, and the fix is more specific than most people realize.
Why Does Sleep Get Worse as You Get Older?
If you slept fine in your twenties and now spend half the night staring at the ceiling, you are not imagining things. Sleep architecture changes with age, and a big part of the reason is biochemical.
Your body relies on a molecule called NAD+ to regulate its internal clock. NAD+ fuels a protein called SIRT1, which controls the timing genes that tell your brain when to feel awake and when to wind down. A landmark study published in Molecular Cell found that restoring NAD+ levels in aged mice rescued normal circadian gene expression and behavior through SIRT1 dependent deacetylation of the core clock protein PER2. In plain English: when NAD+ drops, your internal clock drifts, and your sleep suffers.
NAD+ levels decline steadily after your thirties. By the time you are in your forties or fifties, you may have lost 50 percent or more of the NAD+ you had at twenty. That decline correlates with lighter sleep, more nighttime waking, and the feeling that no amount of rest leaves you refreshed.
This is not a "just deal with it" situation. If the underlying chemistry is off, no amount of sleep hygiene will fully compensate.
How Common Is Poor Sleep, Really?
You are not alone in this. According to the CDC, 35 percent of American adults report getting fewer than seven hours of sleep per night. Among adults aged 45 to 64, that number climbs to 39 percent. Those are not marginal shortfalls. Chronic sleep deprivation at that level is associated with increased risk of obesity, diabetes, cardiovascular disease, and depression.
In New England specifically, the problem compounds during the colder months. Reduced daylight from October through April disrupts melatonin production and vitamin D synthesis, both of which influence sleep quality. If you live in the Boston metro area and notice your sleep tanks every winter, there is a physiological reason for that.
The wellness industry has responded to this crisis mostly with supplements, apps, and mattresses. Some of those help at the margins. But if your sleep problem is rooted in declining NAD+ levels, depleted magnesium, or a vitamin D deficit, a weighted blanket is not going to solve it.
What Does NAD+ Therapy Do for Sleep?
NAD+ therapy works at the cellular level to support the biological machinery your body uses to regulate sleep. When you receive an intramuscular NAD+ injection at Vivolo, you are directly replenishing the coenzyme that powers SIRT1 and your circadian clock genes.
Research published in Cell Metabolism established that NAD+ biosynthesis itself follows a circadian rhythm. The enzyme NAMPT, which your body uses to produce NAD+, oscillates throughout the day and directly modulates CLOCK:BMAL1 mediated circadian transcription through SIRT1. When your NAD+ supply is low, this entire feedback loop weakens, and your sleep wake cycle loses its precision.
At our Charlestown location, an NAD+ session takes about 30 minutes. Most clients describe a subtle increase in mental clarity and energy within a few hours. The sleep benefits tend to build over the first two to four weeks as your circadian rhythm recalibrates. We typically recommend a loading protocol of weekly sessions for the first month, then monthly maintenance.
NAD+ therapy starts at $65 per session. Many clients pair it with a B12 injection through our Power Couple bundle, since B12 deficiency is another common contributor to fatigue and disrupted sleep.
Are There Other Deficiencies That Wreck Your Sleep?
NAD+ is not the only thing worth checking. Several nutrient deficiencies are strongly linked to poor sleep, and most standard primary care panels do not test for them.
Magnesium is one of the biggest overlooked factors. A meta analysis published in BMC Complementary Medicine and Therapies found that magnesium supplementation reduced sleep onset latency by an average of 17 minutes compared to placebo in older adults with insomnia. Magnesium supports GABA receptor function, which is the same pathway that prescription sleep medications target, but without the dependency risk.
Vitamin D is another one. If you live in the Northeast and have not had your levels checked recently, there is a reasonable chance you are deficient, especially between October and April when UVB exposure drops to near zero at this latitude. Low vitamin D is independently associated with shorter sleep duration and poorer sleep quality.
B12 plays a role as well. It influences melatonin production and helps regulate your sleep wake cycle. Vegetarians, vegans, and adults over 50 are at elevated risk for B12 deficiency, and a simple injection starting at $49 can address it directly.
This is exactly the kind of thing [functional labs](/functional-labs) are designed to uncover. A comprehensive panel starting at $69 can reveal whether your sleep issues have a nutritional root cause that a standard checkup would miss.
What Does a Sleep Focused Visit at Vivolo Look Like?
There is no single "sleep package" because poor sleep has multiple potential causes. What we do instead is figure out which ones apply to you.
If you walk into our clinic at 20 City Square in Charlestown, a short walk from the Community College stop on the Orange Line, here is what a typical visit might involve. Our registered nurses, with backgrounds from Mass General and Brigham and Women's, will talk through your symptoms and history. If bloodwork makes sense, we can run a functional lab panel that same day covering vitamin D, B12, magnesium, thyroid markers, cortisol, and inflammation markers.
Based on results, a protocol might include NAD+ therapy to restore circadian function, B12 or vitamin D injections to correct deficiencies, and ongoing support. For clients who want to go deeper into hormone optimization or peptide therapy for sleep, Spencer Mead, PA C, is available through our partnership with Magna Health to design a personalized plan.
No appointment is needed for IV therapy or injections. Walk ins are welcome. If you are coming from downtown Boston, the North End, Cambridge, Somerville, or Medford, the clinic is an easy trip.
When Should You Actually Seek Help for Sleep?
Most people wait far too long. They try melatonin gummies, change their mattress, delete social media from their phone, and cycle through various over the counter remedies for months or years before looking at the underlying biology.
Here is a reasonable benchmark: if you have been sleeping poorly for more than four weeks and basic hygiene changes have not helped, it is worth investigating the biochemistry. Persistent fatigue that sleep does not fix, brain fog during the day, or waking up at 3 a.m. consistently are all signals that something deeper may be going on.
The approach at Vivolo is not to replace your doctor. If you have a diagnosed sleep disorder like obstructive sleep apnea, that requires its own treatment. What we address is the nutritional and cellular side of sleep that most medical visits do not cover in depth.
If you want to find out whether a nutrient deficiency or declining NAD+ is behind your sleep problems, you can walk in any time or start with a functional lab panel to get a clear picture of where you stand.
