How We Grade Consensus
Each ingredient in this stack has its own research snapshot. For every benefit we retrieve the relevant peer-reviewed literature and classify each study by whether its findings support (Yes), partially or conditionally support (Possibly), or do not support (No) the claim. The donut shows the share of studies in each category; the number is the percentage that support the benefit.
Follow any ingredient above to read the full studies behind its grades. Grades reflect the weight and direction of the current evidence, verified by the Scientific Advisory Board.
