To study the bioavailability and bioequivalence of four Ashwagandha extracts in healthy adults

Completed

Conditions: Bioavailability and bioequivalence of four Ashwagandha extracts

Registration Number: CTRI/2020/10/028397

Lead Sponsor: Arjuna Natural Private Limited

Brief Summary: This study will evaluate the bioavailability and bioequivalence of actives of Ashwagandha (Withanolides) in blood plasma from oral consumption of four formulations of Ashwagandha (Withania somnifera) extracts in capsule form. The sample size of the study will be 16 healthy volunteers who give voluntary informed consent. The screening period will be within 21 days prior to day of dosing. Subjects will be housed in the clinical facility from not less than 11.00 hours pre-dose to ensure at least 10.00 hours fasting prior to administration of investigational product and will remain in the facility post-dose until at least 24.00 hours in each period, provided they are not suffering from any adverse event. There will be a total of 4 such periods. There will be a washout period of at least 07 days between each dose administration. In each period there will be a total of 17 blood collection at different time points from a participant.
