Micronutrients & recovery
Restricting daily sodium intake to approximately 2 grams (5 grams of salt) reduces systolic blood pressure by approximately 7 mm Hg in hypertensive individuals.
Limit your daily sodium intake to about 2 grams (roughly one teaspoon of salt). Focus on avoiding processed and restaurant foods, which are the main sources of sodium, and use natural ingredients and herbs for flavoring. This single change can lower blood pressure by an amount comparable to taking a blood pressure medication.

For adults with elevated BP or hypertension, sodium intake should be restricted to approximately 2 g/day (equivalent to 5 g of salt or roughly 1 small teaspoon)... Compared with an intake of approximately 4,500 mg/day, a low-sodium diet (≤1,500–2,300 mg/day) reduces BP by about 3/2 mm Hg in normotensive individuals and by 7/3 mm Hg in those with hypertension
