| Popis: | To examine the effects of betaine on serum lipid profile, plasma homocysteine concentration and hemostatic factors in healthy subjects.Altogether, 63 volunteers (27 ± 8 years, body mass index 22.6 ± 2.4 kg/m(2)) participated in a placebo-controlled, randomized, parallel double-blinded study. The intervention lasted for 6 months during which the subjects consumed mineral water 500 ml/day with (betaine group, n = 32) or without (control group, n = 31) a 4-g betaine supplementation.There was a significant interaction of time and group (general linear model) in serum total and low-density lipoprotein (LDL)-cholesterol concentrations and total-to-high-density lipoprotein (HDL)-cholesterol ratio without a significant difference between or within the groups. Concentrations of serum HDL-cholesterol, triglycerides or oxidized LDL did not change during the study. Plasma homocysteine concentration did not change in either of the groups. Plasma plasminogen activator inhibitor 1 concentration increased in the betaine group (P = 0.028) and decreased in the control group (P = 0.006). There was a significant interaction of time and group (general linear model) in plasma fibrinogen and blood hemoglobin concentration without a significant difference between or within the groups. There were no changes in parameters regarding the function of the liver or kidney.Betaine had no effect on serum lipid profile in long term in young healthy subjects. The lowering effect on plasma homocysteine concentration was weak. |
