The goal of this clinical trial is to learn whether a natural-origin nutritional supplement, combined with a functional exercise program, can improve psycho-emotional, cognitive, functional, and neuroendocrine health in perimenopausal women. The study will also help determine the safety of this combined intervention. The main questions it aims to answer are: * Does the combined intervention improve mood, sleep quality, menopausal symptoms, and cognitive performance? * Does it enhance physical function and neuroendocrine regulation? Researchers will compare the supplement to a placebo. All participants will follow the same supervised functional exercise program. Participants will: * Take a daily nutritional supplement or placebo for 10 weeks * Attend three weekly supervised functional exercise sessions (45-60 minutes each) * Complete pre- and post-intervention evaluations including questionnaires, physical and cognitive tests, and blood samples for biomarker analysis.
This study is a randomized, double-blind, placebo-controlled clinical trial with parallel groups, designed to evaluate the effects of a natural-origin nutritional supplement combined with a functional physical exercise program on psycho-emotional, cognitive, functional, and neuroendocrine variables in perimenopausal women. Participants will be randomly assigned to the intervention groups, with both participants and outcome assessors blinded to group allocation (double-blind design). All study groups will receive a functional exercise intervention, in addition to the nutritional supplement or placebo. The study will last a total of 10 weeks and will include a supervised functional exercise program consisting of three weekly sessions, each lasting 45 to 60 minutes. Pre- and post-intervention assessments will be conducted, including validated questionnaires on sleep quality, mood, general well-being, and menopausal symptoms; objective cognitive tests (attention, working memory, and executive functions); physical fitness assessments (strength, agility, gait speed, body composition); and blood analyses of neuroendocrine biomarkers (cortisol, BDNF, IL-6, TNF-α, GABA, and serotonin). This methodological design will allow for both within- and between-group comparisons and the analysis of potential interactions between the interventions, in order to determine their efficacy and safety as non-pharmacological strategies to improve the overall health of perimenopausal women.

Participants in this group will receive an oral daily dose of the natural-origin nutritional supplement in combination with a supervised functional exercise program (3 sessions per week, 45-60 minutes each) for 10 weeks, composed by three exercise blocks: 1) joint mobility and postural control exercises block, 2) functional strength block with three sets of two explosive strength exercises using elastic bands at 70% of 1RM and, 3) coordination and agility exercises block.
Participants in this group will receive an oral placebo supplement identical in appearance to the active supplement, together with the same functional exercise program for 10 weeks.
