Purity Products overselling resveratrol/curcumin/greenteaxtract on 550 radio

I don't mind cycling through resveratrol/curcumin/greenteaxtract among my supplements but the Purity Products promo on radio this morning is overdone in terms of urgency, vocal pitch and pricing/quality. I can only listen for 5 minutes because of the over-excited fake interview style they sell by, as opposed to the natural voice interviews done by the local health food store here, Healthy Habit.
