Many natural diet supplements contain dandelion as an ingredient. Nothing sounds more natural or harmless, right? Dandelion doesn't aid in fat loss, but it can cause loss of water weight by acting as a diuretic. Any weight lost will come back as soon as you drink a glass of water.

Potential dangers: dehydration, electrolyte abnormalities

Check the label - Dandelion may also be listed as Taraxacum officinale.

Our advice? Avoid products that contain dandelion.
