Questions
Q. I have noticed that many Irwin Naturals products have Bioperine in the formula. What is the Bioperine for?
  A. Irwin Naturals adds Bioperine with the thought that it may enhance absorption of the supplements.

Q. I bought Steel Libido by Irwin Naturals and found it to be effective, then I tried Passion Rx and it was effective too. Did Dr. Ray Sahelian formulate both Steel Libido by Irwin Naturals and Passion Rx?
   A. Yes. Steel Libido by Irwin Naturals was formulated in 2001 while Passion Rx was formulated in 2004 for Physician Formulas and continues to be reformulated with each batch to make it more effective with fewer side effects.

Q. Let me start by saying I used to read your site all the time when I was combating some issues with anxiety and depression. I wanted to try out some of your ideas around supplements for brain chemistry but was too skeptical to take a formula. It seemed somewhat pie in the sky. Having said all that, I started taking Steel Libido for Women by Irwin Naturals about 3 weeks ago. I missed not having the urge to have sex and thought it would be a harmless experiment. I don't know how close it is to your original Steel Libido formula, but I just wanted to say I feel very good taking it. Not just my libido, but it feels as if a cloud has lifted off me. I feel clear and bright. I intend to keep taking Steel Libido for Women. Now I know you didn't put together this formula but Irwin Naturals claims the big difference in this formula is a few specific herbs for women and the removal of a couple of herbs for men.

Q. I saw the 12 in one soft gel capsule multi on TV promoted by klee Irwin. Have you had a chance to look at the ingredients in this 12 in one soft gel capsule multi product, and do you think this is a good product to invest in. Basically, does 12 in one soft gel capsule multi work?
   A. It's really difficult to say much about a multivitamin product unless long term studies are done which is not likely since it would be too expensive to do. The ingredients in 12 in one soft gel capsule multi look fine.
