Sorry to lower the tone but I started taking a turmeric supplement a couple of months ago, in the hopes of alleviating joint aches and pains/arthritis and I rather think that I have been experiencing a higher incidence of flatulence, particularly, ahem, of the odiferous variety. Has anybody else experienced this with turmeric?

Not really a scam or fraud, but I wasn't sure where else to put it.
