[Clinical study on a randomized, double-blind control of Shenwu gelatin capsule in treatment of mild cognitive impairment]
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica (2007) · Rct · n=166
Shenwu gelatin capsule has certain effects on mild cognitive impairment.
Based on RCTs showing cognitive improvements in healthy adults and dementia patients. Effect sizes were modest and some studies used combination therapy. Higher doses associated with increased headache risk.
Based on limited RCTs (n=166, n=64) and observational studies (n=276) in cognitive impairment populations. Meta-analysis effect size 0.439 suggests moderate benefit. Studies primarily in elderly/dementia patients, not healthy adults. Fat-soluble compound requiring food intake for absorption.
