Parkinson's disease
Supplements studied for parkinson's disease.
Overview
Black Tea (WA 44; low effect size, medium evidence, low trust) has medium-strength observational evidence linking regular intake to lower Parkinson's disease risk, with stronger associations in men drinking several cups daily. Vitamin E (WA 40; very low effect size, high evidence, medium trust) dietary intake may be associated with lower development risk, but supplements did not improve symptoms or slow progression in people with established disease.
Tyrosine (WA 32; very low effect size, low evidence, medium trust) did not improve orthostatic hypotension despite raising blood levels in one trial. Vitamin D (WA 52; low effect size, high evidence, medium trust) and Flaxseed Oil (WA 44; low effect size, low evidence, medium trust) have limited or modest signals in small studies.
