Could everyday vitamins tame brain inflammation linked to obesity?
NCT ID NCT07782411
First seen Aug 24, 2026 · Last updated Aug 25, 2026 · Updated 1 time
Summary
This trial tests whether taking vitamin C, vitamin E, or both daily for 12 weeks can lower markers of brain inflammation and change appetite-related brain signals in Mexican adults with obesity. Participants are randomly assigned to one of the supplements or a combination, and researchers measure inflammation and neuropeptide levels before and after the intervention. The goal is to see if these common vitamins might improve brain health and appetite regulation in people with obesity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E), taken alone or together
- What this could lead to
- If effective, these common vitamins could offer a simple, low-cost way to ease brain inflammation and appetite dysregulation in obesity, potentially supporting weight management.
- What could go wrong
- This is an early-stage trial with a modest size, and results may not apply broadly. Vitamins may not meaningfully change brain markers, and high doses can cause side effects like stomach upset.

Inclusion Criteria: 1. Adults aged 40 to 59 years, Mexican men and women. 2. Obese group: Body mass index (BMI) \> 30 kg/m²; body fat percentage \> 25% in men and \> 35% in women; waist circumference \> 90 cm in men and \> 80 cm in women. 3.
