Efficacy and Safety of a Drinkable Nutraceutical for Hair Loss in Patients Using GLP-1/GIP Receptor Agonists

March 19, 2026 updated by: Olistic Research Labs S.L.

Evaluation of the Efficacy and Safety of a Drinkable Nutraceutical in Improving Hair Loss in Patients Treated With GLP-1/GIP Receptor Agonists: a Double-blind, 1:1 Randomized, Placebo-controlled Study.

The purpose of this clinical trial is to evaluate the efficacy of Olistic© Next Women, a nutraceutical supplement, compared with placebo in improving hair loss in patients undergoing treatment with GLP-1/GIP agonists. This 6-month, randomized, placebo-controlled clinical study investigates whether daily supplementation with Olistic© Next Women leads to significant improvements in hair loss in this patient population. In addition, the study assesses the safety and tolerability of the product throughout the treatment period.

  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Placebo Arm
Drinkable formulation consisting of an excipient formulation designed to mimic the organoleptic properties of the active product, reproducing its color and texture while achieving a highly similar taste profile.
Experimental: Active Product Arm
Drinkable multifactorial food supplement in liquid form, administered once daily in a 25 mL single-dose vial, for a duration of 180 days.

Outcome Measure
Measure Description
Time Frame
Self-assessment questionnaire
Time Frame: From baseline to Day 180.
Subject-reported perception of hair condition assessed using a 12-item questionnaire covering perceived hair density, hair shedding, hair strength, hair volume, appearance, and scalp condition. Each item is rated on a 5-point Likert scale ranging from "strongly disagree" to "strongly agree." Higher scores indicate greater perceived improvement in hair and scalp condition.
