July: Peak activity season — optimise performance with the right stack
ZMA (Zinc, Magnesium, B6) is a well-established combination in sports nutrition. Athletes lose significant zinc and magnesium through sweat, and deficiency in either directly impacts testosterone production and sleep quality.
Our formula improves on traditional ZMA by using bisglycinate forms (not oxide) for both zinc and magnesium, dramatically improving absorption.
Benefits

- ✓Sleep quality

Dosing Guide
How to take Zinc + Magnesium (ZMA-Style) — Testosterone Support
Take 3 capsules 1 hour before bed on an empty stomach. Do not take with dairy or calcium supplements.
Always read the label. Consult a healthcare professional if you have any medical conditions or take prescription medication.
Quality & transparency
Why form matters
Medibro uses
Magnesium Bisglycinate
~80% absorbed
Others often use
Magnesium Oxide
Lower bioavailability
Glycinate is chelated — bound to an amino acid that the gut treats like food, not a mineral.
Oxide form passes through largely unabsorbed and commonly causes digestive discomfort. Studies show bisglycinate delivers 3-4x more elemental magnesium to cells.

Supplement Interactions
What can I safely combine this with?
Magnesium is required to convert Vitamin D to its active form. Without adequate magnesium, Vitamin D supplementation is far less effective.
Magnesium and zinc can compete for absorption. Take at least 2 hours apart for optimal uptake of both minerals.
Magnesium and calcium work together in muscle contraction/relaxation. A 2:1 calcium:magnesium ratio is generally recommended.
⚕️ Always consult a healthcare professional before combining supplements with medication.
Stack Synergies
Science-backed pairings for better results
Magnesium is D3's essential co-factor — both nutrients activate each other synergistically
B6 significantly increases intracellular magnesium uptake and retention
Complementary minerals supporting immune function, testosterone, and sleep quality

Customer reviews
- ★★★★☆Luke F.Verified buyer20/04/2026Night sweats and recovery improved
High-volume training was causing night sweats (cortisol dysregulation). ZMA has completely resolved this. Recovery is faster and I can train higher volume without accumulating fatigue. Classic stack for a reason.
- ★★★★☆Oscar Y.17/04/2026Standard ZMA formula done well
Correct ratios and meaningful doses. Much better than some cheap ZMA products I have tried.

- ★★★★☆Craig N.Verified buyer08/04/2026Take on empty stomach 30 mins before bed
Key to ZMA: must take on empty stomach (calcium blocks absorption) and 30-60 minutes before bed. Following this protocol the effects on sleep and testosterone are significant. Good quality, properly formulated.

- ★★★★★Steve P.Verified buyer03/11/2025Testosterone up, sleep deep
ZMA stack is the gym classic for a reason. Zinc + magnesium + B6 — all three are depleted by intense exercise. My free testosterone is measurably up (blood test confirmed), sleep is deeper, and morning energy is better. Don't overthink it, it works.
- ★★★★★James W.25/10/2025Libido and energy both improved
Mid-30s and noticed the classic testosterone-related decline. ZMA for 3 months and the difference is clear — energy, libido, strength. Blood test showed testosterone in upper-normal range for first time in years. Clean, properly dosed formula.
- ★★★★★Marcus D.Verified buyer08/09/2025Better sleep than any dedicated sleep supplement
Have tried magnesium alone, valerian, melatonin. This ZMA stack beats all of them for sleep depth. The zinc component is probably key — so many athletes are zinc-deficient. Wake up genuinely refreshed.
