Gymnema Sylvestre Research The active ingredient in Gymnema Sylvestre

uptake (Kimura, I. 2006).
By normalising and

Sylvestre is an effective weight loss supplement particularly when combined with
other weight loss supplements like Hydroxycitric Acid (Preuss et al., 2004).
In this 8 week study subjects showed an average 5-6% reduction in their Body
Mass Index indicating a significant reduction in body fat.

Sylvestre to be an effective weight loss supplement (Luo et al., 2006). As
well as reducing body fat Gymnema Sylvestre significantly reduced the bad "LDL"
cholesterol whilst increasing levels of the good "HDL" cholesterol. This
means that Gymnema could prove to be a useful tool for controlling/reducing
blood cholesterol levels.
