I have a question about this product and I cannot find an answer online. the adrenal glands are composed of the medulla and the zona. There are 3 parts to the zona: 1 produces cortisol, 1 produces aldosterone and the other produces hormones. My question is : does the adrenal cortex extract contain all 3 parts of the zona or just the part that contains cortisol ? My concern is due to the fact that ACTH regulates all of the molecules the adrenals produce yet it is regulated only by cortisol. So, if one takes a product that contains cortisol, you run the risk of a deficiency in the other items the adrenal glands produce due to the fact it will reduce ACTH. If the ACe product contains these other items, this would help the deficency. I hope this makes sense and someone out there can help with my question.
