Evidence Library
Health claims, graded against what the research actually shows.
Every topic is graded using AEVYNTA’s evidence framework. When the science is weak, that is stated plainly. When claims outpace the evidence, you will know.
Evidence grades
Sleep and Health Outcomes
Consistent, high-quality evidence links sleep duration and quality to metabolic health, cardiovascular risk, immune function and cognitive performance.
Time-Restricted Eating
Promising evidence for metabolic benefits, but effect sizes are modest and many studies are short-term. Not clearly superior to standard caloric restriction for most outcomes.
Omega-3 Supplementation
Good evidence for cardiovascular and anti-inflammatory effects, particularly from dietary fish. Supplement benefits are more modest and dose-dependent.
Vitamin D and Health
Observational evidence strongly associates vitamin D deficiency with poor health outcomes. Whether supplementation improves outcomes in non-deficient individuals remains genuinely contested.
