The Claim
Daily consumption of high-polyphenol rooibos tea for six weeks is well tolerated in adults with metabolic syndrome, with no adverse events reported, and is associated with improved postprandial cardiometabolic health.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with metabolic syndrome who drank high-polyphenol rooibos tea every day for six weeks did not experience any adverse effects and showed improvements in blood sugar and lipid responses after meals.
See the scientific wording
