Micronutrients & recovery
Dietary polyphenol supplementation generally fails to produce significant anti-oxidative or anti-inflammatory effects in patients with metabolic syndrome, despite theoretical benefits.
Do not rely on polyphenol supplements to reduce inflammation or oxidative stress if you have Metabolic Syndrome. The evidence shows these supplements generally do not significantly improve these specific markers in humans, even if they help with weight or blood pressure. Focus on whole dietary patterns like the Mediterranean diet instead.
In numerous clinical studies, antioxidative and anti-inflammatory effects were not significant after polyphenol supplementation in patients with MetS.
Why this rating
Based on a systematic review stating 'numerous' studies showed no significant effect.
