What daily dose of standardised aqueous Ashwagandha root extract was given to participants in the trial?
- A.250 mg
- B.500 mg
- C.750 mg
- D.1,000 mg
Correct answer
Explanation
The correct answer is 500 mg a day, a quantity stated to be equivalent to four grams of raw root powder. Participants were randomly assigned to receive either this standardised aqueous extract or a matching placebo, and the assignment was double-blind, meaning neither the participants nor the assessors knew which arm a person belonged to. The options of two hundred and fifty, seven hundred and fifty and one thousand milligrams are wrong because only the one dose was tested; the study was a safety and tolerability trial rather than a dose-ranging one. Over the twenty-four weeks, liver enzymes, bilirubin, creatinine and blood urea were tracked, and all stayed within the reported reference ranges. The study also looked at whether the extract interfered with the immune response after vaccination, and found virus-neutralising activity above eighty-five per cent in both arms, with no statistically significant difference between the group taking the extract and the group taking the placebo.
