In a prospective cohort of 28,886 US women older than 45 years, 62 dietary intake of calcium was inversely associated with risk of hypertension; however, no change in BP was observed with calcium supplementation. Sacks and colleagues 52 reported no significant effect on BP in 94 patients randomly assigned to receive placebo or combination therapy with either calcium and magnesium or calcium and potassium for 6 months.
Calcium supplementation has not been demonstrated to stop a boost in BP or blood pressure levels. About Trial off Blood pressure level Prevention (TOHP), thirty five 445 normotensive clients was indeed at random allotted to discovered both placebo otherwise step 1 grams from calcium supplements every single day for six months https://datingranking.net/de/pferdesport-dating/. There was zero difference in BP within teams. As well, TOHP-1 tested this new separate outcomes of micronutrients towards BP inside the hypertensive patients with a beneficial diastolic BP of 80 so you can 89 mm Hg. Expands into the losing weight calcium and you may magnesium had just a small effect towards the BP, whereas restrict away from sodium consumption and you will weightloss contributed to significant decrease in the BP. thirty-five

A more recent meta-data out of thirteen RCTs that have ranging from 8 and you can 15 weeks’ pursue-up indicated that members choosing calcium supplements had a statistically extreme reduced systolic BP although not diastolic BP when comparing to a running class. twenty eight Due to the heterogeneity between samples, the data appropriate calcium supplementation and you will BP reduction is poor. Like with almost every other training with various nutritional elements and you will BP, many respected reports had been short from inside the cycle while having got couples participants. More twice-blind placebo-controlled examples out-of longer cycle and better high quality are needed to a great deal more correctly measure the aftereffect of calcium supplements supplementation to your BP and you can cardiovascular effects.
