The active ingredient in Sweet Defeat is an herb called gymnema silvestre. It’s been used for centuries in traditional medicine as a treatment for diabetes. In fact, the Hindi name for this herb translates to "destroyer of sugar."

Modern pharmacological research seems to support this traditional wisdom. Compounds extracted from gymnema have been shown to reduce the absorption of sugar from the intestinal tract and boost insulin production, all of which could help lower blood sugar. Animal testing confirms that gymnema reduces blood glucose levels. 

Lab rats given gymnema extract also eat less and lose weight. As a result, you’ll also find lots of weight loss supplements containing gymnema. Unfortunately, the research on humans is all but non-existent. And, as we know all too well, what works for lab rats does not always work for humans. I wouldn’t waste your money on gymnema-based supplements for weight loss.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
