Butterworth Health · The protocol library
You're not just getting older.
You're running low.
Ageing is less about time than about decline — nitric oxide, nutrition and hormones that can be measured, addressed and rebuilt. Nineteen practitioner-designed protocols from Jeff Butterworth N.D, thirty years in clinical practice. Free for Butterworth Health customers — read them online or download any of them.
Start here.
The Method is the whole approach on eleven pages. The diet & lifestyle protocol is the foundation under every plan. The handbook is the complete library in one document.
The master protocol
The Butterworth Method
Why ageing is decline and deficiency — and the three restorations that address it: nitric oxide, bioavailable nutrition and healthy hormone balance, for men and women. Includes the 90-day plan.
The foundation
The diet & lifestyle protocol
The four pillars — diet, movement, sleep and mindfulness — in full: food tiers, fermented drink recipes, the weekly movement plan, sleep rules and the daily breathwork practice.
The complete library
The Butterworth Protocols handbook
Everything in one 116-page document: the Method, the foundation, all eighteen concern protocols and the optimal blood markers reference.
Eighteen protocols. One for your concern.
Each protocol is a five-page plan: why it happens, the 12-week sequence, a printable tracker, the lifestyle pillars, the products and the naturopathic toolkit. Pick the one that matches what you notice most.
Protocol 01
The nitric oxide optimisation protocol
Restore the master molecule of circulation, energy and healthy ageing — and prove it with a 15-second test.
Protocol 02
The cardiovascular protection protocol
Support healthy blood pressure, circulation and cholesterol balance — measured, not guessed.
Protocol 03
The healthy cholesterol & metabolic reset protocol
Address the metabolic dysfunction underneath the numbers on your blood test.
Protocol 04
The energy & mitochondria protocol
Rebuild cellular energy production and end the 3pm crash at its source.
Protocol 05
The sleep optimisation protocol
Earn deep, restorative sleep — the hours when the body heals, repairs and rebalances.
Protocol 06
The nervous system reset protocol
Bring a stuck stress system back into balance with breath, rhythm and the vagus nerve — includes the guided humming practice.
Protocol 07
The men's testosterone support protocol
Support your body's own testosterone production — naturally, without replacement.
Protocol 08
The women's testosterone & vitality protocol
The overlooked hormone of midlife women — energy, muscle, mood and drive.
Protocol 09
The prostate health protocol
Support prostate health and normal urinary function through the hormonal cascade.
Protocol 10
The weight & metabolic reset protocol
Weight gain after 40 is biology, not willpower — the Four-Layer Reset sequence.
Protocol 11
The brain health protocol
Brain health begins with blood vessel health — protect memory and focus for the long term.
Protocol 12
The bone health protocol
Beyond calcium — the loading, hormones and nutrients that keep bone strong.
Protocol 13
The liver & metabolic health protocol
Support the organ that runs clearance, energy and metabolic balance.
Protocol 14
The libido, drive & circulation protocol
Drive runs on circulation and hormones — the modern blueprint for both.
Protocol 15
The herpes protocol
Fewer, milder outbreaks by fixing the terrain — immune balance, lysine, zinc and the arginine detail most people miss.
Protocol 16
The hidden fat protocol
Visceral and ectopic fat — the fat you can't see — is why the scales won't move. Address it at the source.
Protocol 17
The interstitium protocol
Support the body's hidden fluid network: circulation, lymphatic flow and the communication between your cells.
Protocol 18
The nutrient delivery protocol
Nitric oxide is the master regulator of nutrition — help the nutrients you already take actually reach your cells.
Normal is not optimal.
Standard pathology ranges are designed to detect disease — they are based on people who are unwell. If the goal is energy, muscle, cognition and healthy lifespan, these are the ranges to aim for. Take this panel to your GP.
Cardiovascular longevity
| Nitric oxide (saliva) | > 350 mg/L |
| ApoB | < 0.8 g/L |
| hs-CRP | < 1.0 mg/L |
| CAC score | Zero |
Metabolic health
| Fasting glucose | 4.2–4.9 mmol/L |
| HbA1c | 4.8–5.2% |
| Fasting insulin | 2–6 mIU/L |
| HOMA-IR | < 1.5 |
Micronutrients
| Vitamin D | 75–125 nmol/L |
| Omega-3 index | 8–12% |
| Magnesium (RBC) | 0.85–1.10 mmol/L |
| Zinc | 12–18 µmol/L |
Hormones
| Total testosterone | 15–25 nmol/L |
| Free T3 | Upper half of range |
| SHBG | 30–60 nmol/L |
| DHEA-S | Upper third for age |
The complete reference covers inflammation, lipids, kidney and liver markers and the full nitric oxide guide — about 40 optimal ranges on a single printable page.
How to use them.
01
Find your starting point
Take the free health assessment for a personalised picture of which systems need attention first — or simply pick the protocol matching the concern that bothers you most.
02
Run it for 90 days
One protocol, plus the diet & lifestyle foundation. Baseline your numbers in week one — nitric oxide strip, home blood pressure, energy and sleep scores — and follow the sequence.
03
Measure, retest, keep going
Retest at week 12. The numbers tell the story — and the community keeps you consistent.
Don't guess. Test.
Every protocol works better when you can see your starting point. The assessment takes a few minutes; a nitric oxide test strip takes fifteen seconds. Then join the Butterworth Health Optimisation community and let the numbers do the talking.
