Q In Durk and Sandy’s April 2007 article on the use of their special teas for weight loss, they stated that tea polyphenols can help block the action of lipase, thereby preventing the absorption of some fats. Does this mean that fat-soluble supplements (e.g., coenzyme Q10 and fish oil) should not be taken with tea?

JEFF, San Jose

A While the inhibition of lipase from the use of these teas does not significantly alter the amount of fat that is absorbed from the GI tract from any one meal, the results are cumulative and substantial over the long term. Thus, the effect on the absorption of fat-soluble supplements is minimal and not something to be concerned about, provided that you are taking the generous amounts that formulators such as Durk and Sandy recommend. With this proviso, fat-soluble supplements can be taken with the teas.
