Dosages
500 milligrams once daily
What Research Shows
Likely Effective
- Diabetes —likely to improve blood pressure and blood fat levels when used with standard treatment C1, C2
- High blood pressure —likely to lower systolic blood pressure D1
- Non-communicable diseases—likely to lower risk factors G1
May Be Effective
- Allergic rhinitis —may ease nasal symptoms A1, A2
- Obesity —may lower body weight, BMI, and waist circumference H1, H2
Unlikely to Be Effective
- Cognitive and memory performance and mood —unlikely to have an effect B1
- High Cholesterol —unlikely to change cholesterol levels, but may impact triglyceride levels E1, E2
- Nonalcoholic fatty liver disease—unlikely to improve liver function F1, F2

Safety Notes
It is likely safe to take resveratrol in small doses for a short time. Not enough studies have been done to say whether it is safe to take for a long period. Women who are pregnant or breastfeeding should not use wine as a source of resveratrol.
