You can now buy the new Epsom Lotion by Morton's at WalMart, or Amazon. It is only $5.98 at WalMart and rubbed into your
feet or hands/wrists where the veins are near the surface will get into your blood stream easily. Use about a quarter's diameter only on each foot/hand/wrist. A little goes a long way. It is really fantastic and can replace oral if you do it correctly.

If you go to Juvenon.com you can read about carnitine there...as Dr. Ames' supplement is designed to prevent aging effects and perhaps Alzheimer's. He has lots of discussion about it. Juvenon has carnitine and lipoic acid in it. You don't have to buy his product (which tends to be expensive) but his information may be helpful to you.

You are not going to get many answers from doctors to your questions. And in addition some answers they provide are not based on fact or data.
They are not trained about nutrients, unless you see an integrative or holistic physician.

They rely on drug salespeople almost exclusively for their information. And that is often skewed and falsified in some cases.
