White Willow Bark

Quercetin and White Willow Bark are common minor ingredients in several weight loss formulations. Both ingredients have anti-inflammatory properties by inhibiting prostaglandins. A “side effect” of blocking prostaglandin activity is an inhibition of norepinephrine breakdown – so the ultimate effect or quercetin and white willow supplements is to have more norepinephrine around. Norepinephrine is known to interact with a special kind of receptor found on fat cells (beta-3 receptor) to stimulate the breakdown of fat.

Despite this theory, it has not proven to be effective.
