Effects of Dietary Supplements Based on Trace Elements on Voice Parameters and Some Psychological and Physiological Parameters Related to Stress - Single-center, Comparative, Cross-over, Randomized, Double-blind Study Versus Placebo, in Healthy Subjects

Not Applicable

Completed

• Conditions: Stress

• Registration Number: NCT05313867
• Lead Sponsor: Laboratoires Pronutri

Brief Summary

Preliminary data obtained by the company Pronutri, which produces food supplements based on trace metals, suggests that food supplements containing trace metal compounds could act by reducing stress, which could result in effects on various physiological parameters.

Trace elements are pure minerals essential to the functioning of our body, present in very small quantities. They have a precise and fundamental role in biological and information processes: a deficiency can lead to dysfunctions, often at the origin of our daily ailments.

No scientific study has so far been carried out to measure the effects of these molecules on physiological and psychological parameters related to stress in healthy volunteers. The present study therefore aims to test the effects of these tablets containing metals and trace metals on the reduction of stress.
