There are a lot of herbs, vitamins, minerals and other phyto-nutrients that have been studied for their effects on adrenal health.

Here's a good article on The Natural Approach to Adrenal Dysfunction that was published in the Townsend Letter for Doctors and Patients.

There's also a natural supplement called Adrenal Support info that contains many of the herbs and vitamins listed in the Townsend article. For dosage recommendations and ordering info visit Adrenal Support capsules

Hope this helps,
