Persistent tiredness usually has a cause worth finding — we evaluate it medically before recommending anything.
Medically reviewed by Charles Kamen, MD, board-certified neurologist
Feeling tired all the time is one of the most common reasons adults seek help — and one of the most commonly dismissed. At LiveNow Longevity, persistent fatigue is treated as a medical question with real answers, not a vague complaint.
Dr. Charles Kamen, MD — a board-certified neurologist — looks at the underlying drivers: hormones, metabolism, sleep quality, nutrient status, thyroid, and mitochondrial function. Only after understanding what is actually happening do we discuss whether any protocol is appropriate.
Every plan begins with a complete medical evaluation by Dr. Charles Kamen, MD. Individual results vary, and we do not guarantee specific outcomes.
Fatigue is a symptom, not a diagnosis — which is exactly why it is so often mismanaged. Energy depends on a chain of systems working together: your thyroid setting metabolic rate, your adrenal and sex hormones regulating stress and recovery, your mitochondria producing cellular energy (ATP), your blood carrying oxygen and nutrients, and your sleep architecture restoring the brain each night. A weak link anywhere in that chain shows up as tiredness.
Common medical drivers include thyroid dysfunction, low or imbalanced hormones, iron or vitamin D and B12 deficiency, insulin resistance and blood-sugar swings, poor sleep quality (not just quantity), chronic inflammation, and declining NAD+ and mitochondrial function with age. Because the causes overlap, guessing rarely works — labs do.
Our approach is to find the cause before treating the symptom. Dr. Kamen orders a comprehensive panel — thyroid, hormones, metabolic and nutrient markers, inflammatory markers — and reviews your sleep, medications, and history. The plan that follows is built around what the labs actually show, not a preset menu.
Where appropriate, the body's own energy machinery can be supported. NAD+ is a coenzyme central to mitochondrial energy production that declines with age, which is why NAD+ therapy is studied in the context of energy and cellular function. MOTS-c is a mitochondrial-derived peptide studied for metabolism and insulin sensitivity. Growth-hormone-support peptides such as sermorelin are studied in the context of energy, sleep, and recovery. None of these are a default — each is considered only when the evaluation points to it.

Persistent fatigue despite adequate sleep can stem from hormonal imbalance, thyroid dysfunction, nutrient deficiency, metabolic issues, or poor sleep quality (not just quantity). A medical evaluation with labs is the way to find the actual cause rather than guessing.
A comprehensive panel typically includes thyroid markers, hormones, iron studies, vitamin D and B12, metabolic markers (including blood sugar and insulin), and inflammatory markers — tailored to your history. Dr. Kamen reviews the results with you.
Some therapies — such as NAD+ or MOTS-c — are studied in the context of energy and metabolism and may be considered when medically appropriate, but only after evaluation identifies a reason to use them.
It depends entirely on the underlying cause and the plan. Correcting a deficiency or hormonal issue can take weeks; we set realistic expectations after your labs and never promise a timeline.
The initial medical evaluation is $88 and includes a clinical consultation and lab orders if appropriate. Protocol costs depend on your individualized plan.
