This study was performed to determine the favorable effects of garlic on metabolic status and pregnancy outcomes among pregnant women at risk for pre-eclampsia.


This randomized, double-blind, placebo-controlled trial was conducted among 44 pregnant women, primigravida, aged 18-40 years old at 27 weeks' gestation with positive roll-over test. Participants were randomly assigned to receive either one garlic tablet (equal to 400 mg garlic and 1 mg allicin) (n = 22) or placebo (n = 22) once daily for 9 weeks. Fasting blood samples were taken at baseline and after 9 weeks' intervention to measure metabolic profiles and biomarkers of oxidative stress.


Administration of garlic compared with the placebo resulted in decreased levels of serum high sensitivity C-reactive protein (hs-CRP) (-1425.90 versus 1360.50 ng/mL, p = 0.01) and increased plasma glutathione (GSH) (+98.10 versus. -49.87 µmol/l, p = 0.03). A trend toward a significant effect of garlic intake on reducing fasting plasma glucose (FPG) (p = 0.07), insulin (p = 0.09) and increasing quantitative insulin sensitivity check (QUICKI) (p = 0.05) was also observed.


Consumption of garlic for 9 weeks among pregnant women at risk for pre-eclampsia led to decreased hs-CRP and increased GSH, but did not affect lipid profiles, total antioxidant capacity (TAC) and pregnancy outcomes.
