Micronutrients & recovery

Increasing potassium intake, particularly through salt substitution (25% KCl/75% NaCl) in populations with low potassium and high sodium intake, significantly reduces the risk of stroke and cardiovascular events.

If you live in a region where processed foods are common (high sodium) and fruit/vegetable intake is low, consider switching to a salt substitute containing 25% potassium chloride. This simple change has been shown in large trials to significantly reduce the risk of stroke and heart disease, especially if you have high blood pressure or a history of stroke. It is safe for most people, though those with advanced kidney disease should consult a doctor first.

the recent large Phase III SSaSS trial reported that increasing potassium intake (and reducing sodium intake) in populations with low potassium intake and high sodium intake, through salt substitution (25% KCl, 75%NaCl), reduces the risk of stroke in patients at increased cardiovascular risk.
