03
Test & track
The 15-second strip test, plus how to match it with your HRV and sleep scores.
04
Blood tests
Australian lab ranges vs optimal for lipids, ApoB, Lp(a), hs-CRP, homocysteine and blood sugar.
05
BP & cholesterol
A two-phase plan: optimise NO first, then plant sterols and red yeast rice if still above target.
06
The 3-step method
Optimise nitric oxide, correct nutrition, optimise hormones, and why the order matters.

A high-nitrate food guide, a 7-day meal plan, a shopping list and recipes.

A one-page movement plan, the 10-minute breath practice, and printable 12-week trackers.
The Butterworth Health Method
Three steps, in order.
Nitric oxide delivers. Nutrition fuels. Hormones direct. Skip the first and the other two under-deliver.
01
Optimise nitric oxide
Open the vessels so oxygen and nutrients reach every tissue, including your glands and mitochondria.

02
Correct nutrition
Greens, mushrooms, sea vegetables and trace minerals: the antioxidants and cofactors every enzyme needs.
BOOST

Optimise hormones
Support your own production with strength, deep sleep and the right raw materials, in men and women.
Strength · sleep · your own production
Don't guess. Test.
Three numbers, one story.
Your saliva strip shows how much nitric oxide you're supplying. Your wearable shows what that supply is doing to your nervous system, your recovery and your sleep. The guide shows you how to read them together, and exactly which lever to pull next.

A note from Jeff
“In thirty years of practice I've come to one conclusion: optimising nitric oxide is the most potent way of protecting your cardiovascular system. Everything else builds on it.”
You're not getting old. You're running low. Nitric oxide is testable, trackable and responsive. You can see it on a strip in fifteen seconds, and within weeks you'll see its effect in your HRV and sleep scores. This guide is the daily system I use myself and with the people I work with.
