Garlic extract lowered blood sugar levels and improved blood fat profiles in type 2 diabetes
In one study, 60 type 2 diabetics continued to take 500 mg of the blood-sugar medication Metformin twice per day plus either a placebo or 300 mg of garlic extract three times per day. After 24 weeks, the garlic group had 3.12 percent lower fasting blood sugar compared to 0.59 lower for placebo.
For blood fats, compared to placebo, the garlic group had 2-3 percent lower levels of total cholesterol, LDL—the “bad” cholesterol, and total fat levels, also called triglycerides. HDL, the “good” cholesterol, increased 6.72 percent for those who took garlic compared to those who took the placebo.
