Raziskovalci iz univerze v Hertfordshiru so ugotovili, da lahko magnezijevi dodatki ponujajo majhno, vendar klinično pomembno znižanje krvnega tlaka.
Bolezni srca in ožilja so krivci skoraj 50 odstotkov smrti v Evropi. Zvišan krvni tlak ali hipertenzija je glavni dejavnik tveganja za umrljivost iz srca in ledvične bolezni. Vzroki za hipertenzijo vključujejo (vendar ne izključno) kajenje, sedeči način življenja, ki uživa hrano, bogato z natrijem in nezadosten vnos drugih mineralov, kot so kalij, kalcij in magnezij.
"Do sedaj je bilo sumljiva dokaze o učinek magnezijevih dopolnil na krvni pritisk," je dejal Lindsy Kass, predavatelj in strokovnjak za prehrano registrirana na Univerzi v Hertfordshiru. "Tako smo izvedli meta-analizo z analizo podatkov iz dvaindvajsetih poskusov, ki vključujejo 1,173 ljudi, da se oceni vpliv magnezija na krvni tlak."
"Until now, there's been inconclusive evidence regarding the effect of magnesium supplements on blood pressure," said Lindsy Kass, Senior Lecturer and registered nutritionist at the University of Hertfordshire. "So we conducted a meta-analysis by analysing data from twenty-two trials involving 1,173 people to assess the effect of magnesium on blood pressure."
In the trials, the magnesium supplementation doses ranged from 120 to 973 mg with between 3 to 24 weeks of follow-up. Although not all individual trials showed significance in blood pressure reduction, by combining the trials, the overall data indicated that magnesium supplementation reduced both systolic and diastolic blood pressure. With the best results observed at the higher dosages.
"The clinical significance in the reductions found from this meta-analysis may be important in helping to prevent hypertension and associated risks around cardiovascular disease," said Lindsy. "And is worthy of future trials using solid methodology."
