How are your energy levels, really?
Energy isn't random — it tracks a handful of everyday habits. Answer a few questions to score your vitality, see which factors are draining it most, and where small changes pay off first.
What actually drives your energy
Day-to-day energy is less about willpower and more about a few inputs your body runs on. Sleep is the foundation — quantity and consistency both matter. Regular movement improves how efficiently your cells use fuel. Chronic stress quietly burns through your reserves. And the steadiness of your meals decides whether you glide through the afternoon or crash into it.
Where to start
- Protect sleep first — a consistent 7–9 hours beats almost every other intervention.
- Move daily, even briefly. A short walk after meals helps blunt afternoon crashes.
- Build protein-forward meals to keep blood sugar — and energy — steadier.
- Create real recovery from stress: walks, breathing, time off screens.
- Keep alcohol modest; it fragments sleep more than most people realize.
NAD+ and cellular energy
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell and central to the reactions that turn food into usable energy. Its levels naturally decline with age. Some people explore NAD+ therapy as part of an energy and healthy-aging routine — at Pallas, it's prescribed only when a US-licensed clinician determines it's appropriate for you.

Common energy questions
Sleep is the single biggest lever for most people — both how many hours and how consistent your schedule is. After that, regular movement, stress load, blood-sugar stability across the day, and alcohol intake all move the needle. Age sets a slowly shifting baseline, which makes the daily habits matter more over time.
A mid-afternoon dip is partly natural circadian rhythm, but it's amplified by short sleep, refined-carb meals that spike and drop blood sugar, dehydration, and long stretches without movement. Protein-forward meals, a short walk, and steady hydration usually flatten the crash.
It's a weighted lifestyle self-assessment: each answer (sleep hours, active days, stress level, how often you crash, weekly alcohol, and age) subtracts points from 100 based on how strongly that factor tends to affect energy. It's a directional tool to spot your biggest drains — not a clinical measurement.
If fatigue is persistent, sudden, or comes with other symptoms — unexplained weight change, low mood, breathlessness, heavy snoring, or feeling unrefreshed despite enough sleep — it's worth a medical visit. Thyroid issues, anemia, sleep apnea, depression, and other conditions can all present as low energy.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that's central to the reactions converting food into usable cellular energy. NAD+ levels naturally decline with age. Pallas offers a clinician-prescribed NAD+ program; whether it's appropriate for any individual is determined by a US-licensed clinician who reviews their health history.
No. This tool scores lifestyle factors only — it does not measure NAD+ or any biomarker. Measuring NAD+ requires lab testing and clinical interpretation.
