L'essai clinique NCT07341308 est une étude interventionnel pour Metabolism Changes, Vitamine D. Son statut actuel est : en recrutement. L'étude a débuté le 17 mars 2025 et vise à recruter 20 participants. Dirigée par l'Université d'État du Colorado, l'étude devrait être terminée d'ici le 8 décembre 2026. Les données du site ClinicalTrials.gov ont été mises à jour pour la dernière fois le 14 janvier 2026.
Résumé succinct
The goals of this clinical trial are to determine whether or not vitamin C is able to: (1) increase the body heat generated by the sympathetic nervous system; and, (2) increase circulating vitamin D concentration during sympathetic nervous system stimulation in adult humans aged 18-40 years who meet the criteria for overweight based on body mass index. The main question it aims to answer are:
- By how much does bod...
Description détaillée
Participants will be required to visit the lab twice. During each visit, beta-adrenergic receptors will be stimulated with isoproterenol. The two visits are identical in every way with one exception: during one visit the isoproterenol will be delivered with saline only, and during the other visit the isoproterenol will be delivered with saline and vitamin C. The order of the visits will be randomized. Body temperatur...Afficher plus

|---|---|---|
Body Temperature | Body temperature will be measured using an oral thermometer | Prior to and immediately after a dose of isoproterenol. This corresponds to 0 minutes (baseline) and immediately after each dose of isoproterenol at minutes 30, 60 and 90. |
Vitamin D | Circulating vitamin D concentration | Prior to and immediately after a dose of isoproterenol. This corresponds to 0 minutes (baseline) and immediately after each dose of isoproterenol at minutes 30, 60 and 90. |

Accepte les volontaires en bonne santé
Oui
- Age 18-40 years (inclusive)
- Body mass index greater than or equal to 25 kg/m2 and less than 30 kg/m2
- Weight stable (no change in body mass greater than 5 Lbs. within the previous 6 months.
- Willing to abstain from caffeine and alcohol for 24-hours prior to two different study visits
- Competency in English as assessed by comprehension of the Informed Consent. This is study involves invasive procedures and infusion of a systemic vasoactive agent (isoproterenol); for safety reasons, the ability for clear and rapid communication will be necessary between the research participants and the investigators.
- History of autonomic, cardio-pulmonary, and/or metabolic disease (including heart failure, hypertension, arrhythmia, vascular disease, and/or diabetes)
- Pregnancy or breast feeding
- Habitual use of tobacco/nicotine products or recreational drugs (2 or more uses within the previous month)
- History of a "sulfite allergy" as it is a relative contraindication to isoproteronol use.
- Has ingested vitamin supplements and/or antioxidant supplements during the previous 4-weeks (e.g. Vitamin C, Vitamin E, Multi-vitamins, etc.)
