Abstract
In the present study the effect of oral physiological magnesium
supplementation on atherogenic risk factors such as serum lipids
and
blood pressure was examined. Sixty-nine patients with
hyperlipidaemia of Frederickson types IV and IIb were
investigated with
regard to renal function, blood pressure, serum cholesterol,
triglycerides, HDL-cholesterol and LDL-cholesterol, and plasma
and
erythrocytic magnesium concentrations. All patients were on
cholesterol-poor (< 90 mg cholesterol/d) and energy-restricted
diet (<
1200 kcal/d). Thirty-seven patients received 500 mg magnesium
(oral) daily as a supplement. All measurements were performed
before and four weeks after starting treatment. The results of
our study show that oral physiological magnesium supplementation
in
addition to the usual dietary measures can be beneficial with
regard to serum triglycerides (values, means +/- SD, decreased
from
198.17 +/- 47.01 to 163.20 +/- 40.55 mg/dl, P < 0.05), but
exerts no positive effect on blood pressure or serum cholesterol.
Furthermore, erythrocyte magnesium concentration increased
significantly during oral physiological magnesium supplementation
(values, means +/- SD, increased from 1.72 +/- 0.22 to 1.91 +/-
0.18 mmol/litre, P < 0.05), whereas plasma magnesium
concentrations did not change significantly.
