Quick Take

Consider only if you have prediabetes or type 2 diabetes — evidence is promising but limited.

Gymnema sylvestre is a woody climbing shrub native to India and Africa whose leaves have been used in Ayurvedic medicine for centuries, usually as tea or extract. Its active compounds, gymnemic acids, appear to reduce intestinal glucose absorption and increase pancreatic insulin secretion. Human trials suggest it can lower fasting blood glucose and HbA1c in type 2 diabetes, may improve cholesterol levels, and might support modest weight loss. It also temporarily blocks sweet taste receptors on the tongue. Those most likely to benefit are adults with type 2 diabetes, prediabetes, or significant

How It Works

Gymnemic acids in the leaves suppress glucose absorption in the gut and may stimulate insulin secretion from pancreatic beta-cells. They also bind to sweet taste receptors on the tongue, temporarily blocking the sensation of sweetness and potentially reducing sugar intake.
