I have been diagnosed with adrenal fatigue and the glandulars can help, but have an equal and opposite downsides. The healthy adult adrenal gland makes 10 to about 35 mg of cortisol per day. The average is around 20 to 25 mg a day. I used a product called IsoCort of at least two years. IsoCort is an adrenal cortical extract that contains 2-1/2mg of cortisol per tablet and is well standardized by the company. Adrenal glandulars are not regulated as to dose or hormone levels as a rule. They also can be made from the whole adrenal gland or just the cortex, which is the part of the gland that fatigues. The whole gland extract will have hormones that you probably don't need. With most products like these, you do not know the dose you are getting. On top of that, you can get hormones that can worsen a-fib. For example; IsoCort contains all the hormones of the adrenal cortex, which includes aldosterone and DHEA. These are androgens that can have an adverse affect on a-fib. They do in my case. continual use of adrenal extracts or licorice root are well known causees of a-fib.
A person can also use licorice root to treat adrenal fatigue, as it works by slowing the breakdown of cortisol and other adrenal hormones from the liver and thus keeps your own hormones in the system longer. 1 teaspoon of licorice root extract in a tea is very roughly equivelent to 4 mg of cortisone. (Do not use degyccerized licorice as the active ingredient is removed.) This simple herb is also associated with the development of a-fib due to it's affect on the concentrations of other adrenal hormones besides cortisol.
The other downside to taking anything with cortisol or cortisone in it is that it weakens your own adrenals. If they are already weak, then it can be helpful by making you feel better, but the dose is critical. If you take more than you need, then you will weaken your adrenals further and have an adverse affect on the pituitary regulation of the adrenals. Even small doses can cause suppression of pituitary regulation. (been there done that). For example; in William Jeffries "Safe uses of Cortisol" he points out that if a person takes 1/2 of their daily needs in cortisone or about 10 mg a day for a person that needs 20 mg a day, they will weaken their own adrenal gland by over 60%. My personal experience is that cortisone use will make you feel better if you have weak adrenals, but at a cost of suppressing your pituitary regulation of the adrenals and weakening of your gland to the extent that you will find that you cannot handle stress well at all. You'll feel good as long as you don't have stress. Cortisone use, whether in prescription meds or in adrenal glandulars reduce adrenal reserve or the capacity of the gland to respond to stresses that exceed your daily needs. So, taking cortisone can result in a limited life as far as stress is concerned.
In my case, this loss of adrenal reserve from using cortisone has resulted in increased a-fib. Since a-fib can be triggered by stress, then every time you have a stress that requires more adrenal hormones than your daily 20 mg, you end up going into a-fib. I can avert it many times by taking extra cortisone at the time of the stress. But, I have to guess how much I need and if I get it wrong, then I will still go into a-fib. Also, because of this situation, I have not been able to get off the cortisone. Any time I try to reduce my dose, then I go into a-fib. Lots of things can require you to need more than 20 mg a day of cortisol. They include a simple walk, a head cold, dental work and mental stress. Stresses like this can double your daily needs of cortisol and some types of dental work can require as much as 90mg of cortisol a day.
So, my point is that you do not want to go down this slipperly slope unless you have to. If you think you have adrenal problems, you should have a 24 hour cortisol test and perhaps an ACTH stimulation test and maybe others. General adrenal fatigue usually can get better with rest, reducing stress, and a change in lifestyle. But, once you get on some type of cortisone pills, you may not be able to get off tjhem and definitely an adrenal glandular is not the way to go if you have a-fib. You will need to take a medication that only has cortisone in it, like hydrocortisone, and not the other hormones found in the glandulars.
It takes just 3 to 4 weeks of using a glandular, or hydrocortisone, or Prednisone to become dependent and to weaken your own adrenals if the dose you take is more than you need. Then you are looking at taking a long time to get off it and having to taper off slowly. It could take months, depending on how long you have been on it. You might not be able to get off like me due to the a-fib that is triggered by the stress on the adrenals caused by tapering off.
So, my advice is to try to cure your adrenals with a good diet, reduction of stress, lots of sleep, and possibly supplements that help the adrenals. If you think you might have something more serious, then you should see an endocrinologist and have some testing. If you have more permanent adrenal function loss, then it might well be worth the down sides to go permanently on some cortisone.
This is one area of treatment that is not simple and it does not have any good solutions.
