The Core Ingredient Is: Zinc

Zinc plays a role in cellular repair, and supports immune function, and helps maintain healthy testosterone levels in men, contributing to recovery and anabolic processes.

This nutrient is provided alongside magnesium and vitamin B6 to support recovery and sleep related processes, with zinc serving as the primary active mineral in this formula.

What Zinc Does?

Zinc participates in immune function, is involved in cellular repair, and contributes to hormonal regulation in line with EFSA guidance on nutrient function.

It supports normal body processes related to sleep quality and recovery as part of a balanced overall programme, in line with NHS and EFSA recommendations.
