Denny: The company is Lifewise Naturals. Their phone number is 800-643-9558. They have a catalog f stuff but I only purchase COQ10 because it's the only one whose price makes sense to me. They sell different strengths with different #s of capsules per bottle and give quantity discounts. For example, the one bottle price of 60 100 mg capsules is $26.50. The three bottle price is $23.85 and the case (12 bottle) price is $22.53/bottle. The current catalog also offers free shipping for orders of $50 or more. No, I don't take NADH but I take a slew of antioxidants against PD and a number of other things to try to fool my body about my age. Paul H. Lauer
