The "Spark Plug" Molecule (And a note on respecting the system)
Why your cells lose power as you age, how to fix it, and a critical update on our clinic operations.
“The flame doesn't burn to vanish, but to illuminate. Let the swift passage of time be a gentle reminder not to rush, but to shine brighter in the moments we have.”
Part 1: Housekeeping (The Clinic System)
Before we dive into the science of cellular energy, I have a quick update regarding the “energy” of our clinic.
As many of you know, I am now personally seeing patients across three locations (North Palm Beach, Port St. Lucie, and our satellite offices). My goal is always to give every single patient my undivided focus and the time you deserve to solve complex health puzzles.
To do this, we are upgrading our scheduling system.
Effective immediately, LifeWellMD is moving to an “Appointment Only” model.
We can no longer accommodate walk-ins. Unexpected arrivals create backups that aren’t fair to the patients who booked ahead, and they fracture the attention I want to give you.
Please call Ann Marie at 561-210-9999 to lock in your time before driving over.
Think of this like a traffic signal—it keeps the flow moving safely for everyone. Speaking of flow and energy... let’s talk about why you might be feeling “low voltage” in your own body.
Part 2: The Deep Dive (The Biological System)
Why you’re “Tired but Wired” (The NAD+ Crisis)
I saw a patient last week who told me, “Dr. Kumar, I eat right, I sleep, but I feel like my battery is stuck at 15%.”
It wasn’t a thyroid issue. It wasn’t laziness. It was a fuel line issue.
There is a molecule in your body called NAD+ (Nicotinamide Adenine Dinucleotide).
If your body is a car, and food is the gas... NAD+ is the spark plug. You can fill the tank with premium organic kale and grass-fed beef, but if you don’t have the spark (NAD+), the engine won’t fire. You just get sludge.
The Bad News: The Decline By the time you are 40, your NAD+ levels have dropped by about 50%. By age 60? You’re running on fumes.
This isn’t just about feeling sleepy. NAD+ is required for:
DNA Repair: It literally fixes the “rust” on your genome.
Sirtuin Activation: These are your “longevity genes.” They stay asleep without NAD+.
Mitochondrial Function: Creating ATP (energy).
When NAD+ drops, your body enters “survival mode.” It shuts down the expensive repair projects (keeping skin young, brain sharp, mood stable) just to keep the heart beating. This is what we call “aging.”
If you’ve ever felt like a high-performance car with a dead battery, the issue isn't your willpower—it’s your cellular ignition. This short visual explores NAD+, the biological 'spark plug' responsible for our vitality, and reveals how we can actively refill the tank when levels run low.
The Good News: You Can Refill the Tank
We used to think this decline was inevitable. It’s not. In Functional Medicine, we look at NAD+ as a lever we can pull.
We use NAD+ IV Therapy in the clinic to flood the system with this molecule, bypassing the gut and going straight to the cells. Patients often describe it as “waking up” or “cleaning the windshield” of their brain.
But you can also support your levels naturally through “Hormesis” (good stress):
Intermittent Fasting
Sauna / Heat Shock
High-Intensity Interval Training
The Takeaway You are not a static machine. You are a dynamic system. Just like we had to optimize our clinic schedule to serve you better, you have to optimize your cellular chemistry to live better.
If you are dealing with brain fog, chronic fatigue, or slow recovery, your spark plugs might be worn out.
Give Ann Marie a call (561-210-9999) to discuss if NAD+ therapy fits your protocol. Just remember—call first!



Solid explanation of NAD+'s role in cellular energy. The spark plug analogy makes sense,especially tying it to that stuck-at-15% feeling so many people describe. What I find interesting is the hormesis angle you mentioned - fasting, sauna, HIIT. Those stressors basically force cells to upregulate their own NAD+ synthesis as an adaptive response. I've noticed intermittent fasting helps with mental clarity way more than just calorie restriction, and the NAD boost probably explains atleast part of that.
