Hair Tissue Mineral Analysis (HTMA) — the cellular record blood tests don't reach.
Hair records 3–4 months of mineral status, exposures, and metabolic patterns — a layered timeline blood tests can't capture. That includes dietary patterns and heavy metals like lead, mercury, and arsenic. Blood shows what's in transit; HTMA shows what's stored.
HTMA complements your standard medical care. Where blood tests show what's circulating right now, HTMA reveals 3–4 months of mineral patterns, exposures, and body-wide metabolic context. Read the full science →

ARL analyses your sample. Gary delivers your HTMA report by email — typically 3–4 weeks from receipt.
Source any recommended supplements (Gary's report includes sourcing notes). Email Gary with questions free of charge — most clients don't need a one-to-one at all.
Submit your second sample. Gary delivers your comparison report — what changed, what worked, what's next.

HTMA reveals patterns across very different health goals.
Recovery, mineral balance, and the deficits limiting your performance.
AthletesFor clients whose blood tests come back "normal" but who still don't feel right.
Chronic healthTrend your mineral status over years. Act on data, not symptoms.
LongevityNon-invasive testing for kids. Behavioural concerns, recurring illness, suspected exposure.
Children100+ countries served. Hair posted internationally; pricing in NZD.
InternationalWithin 8 weeks of following the protocol, my recovery times halved and I was finishing hard sessions with energy to spare. The report was detailed enough to act on immediately.
My HTMA revealed severe magnesium depletion and elevated copper — two things my blood tests never flagged. Four months later I set a personal best in every event.
After seven years of fatigue and "normal" blood tests, my HTMA revealed lead toxicity and an adrenal exhaustion pattern. Twelve months in, I'm working full-time again.
Gary's approach didn't replace my medication — it addressed the mineral environment driving inflammation. The difference in how I feel day to day is extraordinary.
I wanted a data-driven baseline. The HTMA identified early calcification patterns and elevated mercury. Two years later, my follow-up shows dramatic improvement across every marker.
We tested our 18-month-old after she was slow to hit milestones. The HTMA revealed elevated lead — traced to old paint in our rental. Six months in, her development accelerated noticeably.
Gary has practised HTMA for 50+ years. Post-graduate diplomas in Sports Medicine and Rehabilitation, Otago Medical School. Four-time UCI Masters Mountain Bike World Champion — applying the protocols he prescribes to himself.
