Well I was always raised to be thrifty and only purchase from brands I trust. I'm kind of cheating and looked at the ingridents for BeauOxi White and Glow2thione and am going to order from Puritan's Pride. They carry 500 mg of L-Glutathione so as long as you don't mind popping the extra quantity of pills for the quality. I'd recommend doing that instead. That's what I'm going to do also I'm using the money I saved for some msm powder too considering its supposed to boost glutathione levels natually.
