You've tried everything. Your tracker hasn't noticed.
“Your device is not wrong and neither are you. You have spent two years changing the inputs to a system whose capacity nobody ever touched.”
Eighteen months of interventions, one flat line
You check it before you are properly awake. You know your baseline to the millisecond, and you know it has not moved since roughly this time last year. Not for want of trying:
Each one bought you a good fortnight, or nothing you could separate from noise. At some point the score stopped being information and started being a verdict.
A recovery score is an output, not a system
HRV is the gap between consecutive beats. Wide, irregular gaps mean your nervous system relaxed enough to run maintenance overnight. Narrow, metronomic ones mean it stayed braced. Sleep staging and resting heart rate are read the same way - as evidence of work completed.
That work is repair, and repair is cellular. Which makes every number on your dashboard a report on something happening one level below the dashboard - and an output can only be as good as what funds it.
Every one of those was an instruction or a delivery
Instructions and materials
Behaviours you send to the cell, and raw materials you deliver to it. Tracked, adjusted, and about as good as they are going to get.
The machinery that executes them
Mitochondria making energy, repair enzymes clearing damage. No device reports on it, so no protocol asks you to change it.
A better instruction sent to a cell with less capacity to carry it out returns a smaller result. That is the whole reason the line went flat while your discipline kept improving.
Cells run everything. One molecule funds the cells.
NAD⁺ is the coenzyme mitochondria use to make energy and repair enzymes need to clear damage. Two systems, one shared pool, both drawing hardest overnight. When supply is short, energy is paid first and repair takes what is left - which is a slow HRV recovery described in the only language your device has.
It declines steadily with age. By your forties you are running on roughly half what you had at 25, while your training load and your responsibilities have both gone up. Nothing is broken. The budget shrank as the bill grew, and no wearable on the market has a metric for it.

What MUTO is
One product. Sixty capsules, thirty days, two a day. A cellular energy formula built around nicotinamide riboside - the raw material your body converts into NAD⁺ - with every dose printed in full at research level, so you can check it against your existing stack rather than guess. Three jobs, no overlap:
Nicotinamide riboside at 300mg, plus zinc, copper and six B vitamins in active forms.
Your body breaks NAD⁺ down as fast as it makes it. Pterostilbene, quercetin, grapeseed and turmeric extract keep raised levels raised for longer.
CoQ10 to help mitochondria convert it into usable energy, and BioPerine® so the formula is absorbed rather than passed through.
No stimulants, so nothing to feel in the first hour and nothing that flatters tomorrow's readiness score without doing any work.
Run it properly. You already own the instrument.
You have months of personal baseline sitting in an app, which is a better dataset than most published trials have on any individual. Use it.
Screenshot your baseline first
30-day averages for HRV, resting heart rate and sleep, before capsule one.
Change nothing else
One variable at a time or the result means nothing. You already know this.
Read weekly, not daily
A single morning tells you about last night. Feel usually arrives in weeks three to four; data typically moves between day 30 and day 60.
Judge at day 90
If the trend has not moved, tell us and we refund you. No returned pouches, no argument about how you felt.

MUTO is a food supplement and is not intended to diagnose, treat, cure or prevent any disease. It is not a substitute for training, sleep or a varied diet. Consumer wearables are not medical devices and their readings are estimates. If you are pregnant, breastfeeding or taking prescribed medication, speak to your doctor before use.
