Micronutrients & recovery
Use of potassium supplements is inversely associated with stroke risk, particularly in men with hypertension who are taking diuretics.
If you take diuretics for high blood pressure, your doctor may recommend potassium supplements to counteract potassium loss. This study found a strong reduction in stroke risk for this specific group. Do not self-prescribe potassium supplements; consult your doctor for monitoring and dosage.

Use of potassium supplements was also inversely related to risk of stroke, particularly among men taking diuretics (relative risk, 0.36; 95% CI, 0.18, 0.72).
