Optimised Research Labs ZMA-EX Optimiser 90 Capsules BBE October 2026

Natural Testosterone Production Support — Zinc plays a direct role in testosterone synthesis and is one of the most reliably studied minerals for supporting healthy testosterone levels in active individuals. Depletion through sweat is common in athletes — ZMA-EX replenishes it nightly.

Muscle Growth & Protein Synthesis — Zinc is essential for normal protein synthesis and contributes to the maintenance of normal testosterone levels — both of which are directly relevant to building and preserving lean muscle mass during consistent training.

Muscle Function & Recovery — Magnesium contributes to normal muscle function and the reduction of tiredness and fatigue — two EU-authorised health claims. Replenishing magnesium before sleep supports overnight muscle repair and reduces the risk of cramping and tightness.

Sleep Quality Support — Magnesium is well-established for its role in supporting relaxation and sleep quality. Taken before bed, ZMA-EX supports the deeper, more restorative sleep that athletes need for genuine overnight recovery and hormonal restoration.

Energy Metabolism — Both Magnesium and Vitamin B6 contribute to normal energy-yielding metabolism — EU-authorised health claims. Supporting these pathways consistently is particularly important during high training volume periods when energy demands are elevated.

Nervous System & Neurotransmitter Support — Vitamin B6 contributes to the normal functioning of the nervous system and supports neurotransmitter synthesis including serotonin and dopamine — relevant to both mood regulation and the quality of sleep.

Immune System Support — Zinc contributes to the normal function of the immune system — an EU-authorised health claim — helping to maintain immune resilience during intense training phases when suppression is a known risk.

Highly Bioavailable Forms — Zinc Aspartate & Chelate and Magnesium Aspartate are significantly better absorbed than the cheaper oxide forms used in most standard ZMA products, ensuring the stated doses are actually utilised by the body.

Vegan-Friendly — Soy-Free, Gluten-Free, GMO-Free — No CMC — Clean, simple formulation. ORL do not use Carboxymethylcellulose in any of their products.

30 Servings — Outstanding Value — 90 capsules providing a full month's supply at the recommended 3-capsule nightly dose.
