Extreme BP minimizing with extra amounts from potassium from the diversity regarding 1900 in order to 4700 milligrams/d (49–122 mmol/d) could have been said to result in BP decrease in up to 2 to six mm hg to have diastolic BP and you can 2 to 4 mm hg having systolic BP. this new highest variability ranging from overall performance shows the new variability noticed in more degree. on top of that, the end result off potassium on the BP is actually influenced by pretreatment BP level; age; race; sex; comorbid criteria; consumption from salt, magnesium, calcium, and other ions; diet; exercise; weight; brand of potassium made use of; concomitant medicines; and you may duration of play with. a listing of brand new conclusions of all of the meta-analyses towards results of potassium into BP up until now is provided into the Figure step 3.

Overview of meta-analyses out-of studies examining the blood pressure-reducing aftereffects of potassium. 25–twenty-eight SBP indicates systolic blood circulation pressure; DBP, diastolic blood circulation pressure.

Even in the event conflicting show regarding your results of potassium supplementation on BP were reported from inside the scientific studies, 34, thirty-five newer trials features demonstrated overall performance in keeping with that the newest meta-analysis because of the Whelton and associates twenty six (Table II). Gu and you may coworkers thirty six found that modest potassium supplements (60 mmol KCl) taken getting a dozen days led to a decrease in systolic BP, but not diastolic BP, from inside the a Chinese population. Similarly, Kawano and associates 37 documented that an effective 4-month potassium supplementation several months (when 64 mmol/d away from potassium gotten since the sluggish-discharge KCl) resulted in quick however, extreme decreases from inside the workplace, house, and twenty four-hr BP in Japanese group. Braschi and colleagues 38 then checked out the result of low-amount potassium supplements toward BP and discovered one 24 mmol/d regarding slow-discharge KCl administered to own six weeks lead to extreme decrease inside imply arterial stress and you may diastolic BP into the suit volunteers.

Systems which Potassium Reduces BP

Brand new homeostasis away from salt and potassium plays an important role in the endothelium-oriented vasodilatation. 39 Sodium maintenance reduces the synthesis regarding nitric oxide, an arteriolar vasodilator elaborated by the endothelial tissue, and you can increases the plasma level of asymmetric dimethyl-L-arginine, an endogenous inhibitor off nitric oxide development. 40 a nutrition rich in potassium as well as develops from inside the gel potassium, even during the physiological assortment, result in endothelium-oriented vasodilatation because of the hyperpolarizing this new endothelial telephone thanks to pleasure of the sodium pump and beginning potassium avenues. 41 In addition, other suggested components for which potassium is also determine BP were natriuresis, modulation out-of baroreceptor sensitiveness, less vasoconstrictive sensitivity so you’re able to norepinephrine and you can angiotensin II, enhanced gel and urinary kallikrein, increased salt/potassium Within Pase craft, customization during the DNA synthesis, and growth from inside the vascular easy muscle and sympathetic neurological system cells. 42, 43

Losing weight Advice to possess Potassium

Maintaining an adequate intake of dietary potassium (>90 mmol [3500 mg]/d) has been recommended for the primary prevention of hypertension by the JNC 7.13 The Institute of Medicine has recommended a sodium intake <65 mmol/d (3.8 g/d) and an increase in potassium to 120 mmol/d. 44 In 2006, the American Heart Association issued new guidelines suggesting an increase in potassium intake to 120 mmol/d (4.7 g/d), which is the level provided in the DASH diets in which all food is supplied. 14 The Canadian Hypertension Society recommends that the daily dietary intake of potassium should be ?60 mmol, since this intake has been associated with a reduced risk of stroke-related mortality. 45, 46 The most recent European Society of Hypertension guidelines also support an increased potassium intake based on the DASH diet. 18 In addition, the 2003 World Health Organization/International Society of Hypertension statement recommends a diet high in fruits and vegetables, a reduction of dietary sodium intake, and increased dietary potassium intake for reducing the incidence of hypertension. 16 Some sources of high-potassium, low-sodium foods are listed in Table III. 47
