I'm probably missing some key pieces here but I'm confused as to why slowing down your metabolic rate would help with diastolic dysfunction? Maybe your heart wouldn't beat as frequently in the present but that approach would seem to make you even sicker in the long run? You don't have to explain this to me at all so long as you feel comfortable with your treatment plan and long term goals.
You're not taking any statins, are you? Statins are well known to contribute to diastolic dysfunction (as well as pain and other symptoms).
I am not a fan of what I refer to as "kitchen-sink" adrenal formulas. It's like the company got together every single herbal ingredient that has ever been shown to affect adrenals and threw it all together without much thought about anything other than profit.
It's what most everyone (myself included) gets started on and it rarely ever seems to help any but those with the very mildest adrenal issues.
For example, the Innate formula contains the following:
SOURCE; FOODSTATE® AMOUNT
Sensoril ®*** (Ashwaganda Root) - adaptogen, can lower or raise cortisol, may help with thyroid as well
(Withania somnifera) 200 mg
Rhodiola extract (Rhodiola rosea) - adaptogen, can lower or raise cortisol
10:1 (1% rosavins) 200 mg
Astragalus Root - adaptogen, can lower or raise cortisol
(Astragalus membranaceus) 4:1 150 mg
American Ginseng Root -- stimulating to adrenals; produce more cortisol
(Panax quinquefolius) 4:1 100 mg
Sacred Basil (Ocimum sanctum) 10:1 100 mg - reduces cortisol powerfully, lowers cortisol levels
Schizandra Berry (Schisandra chinensis) 4:1 100 mg - adaptogen, can lower or raise cortisol
ADDITIONAL FOODS & EXTRACTS
Indian Gooseberry, Amla 5:1 100 mg - reduces cortisol
Seaweed-Laminaria digitata, and - I can only presume this is included for iodine/thyroid function though iodine may actually provoke autoimmune attacks in those with Hashimoto's (the most common type of thyroid disease)
Ascophyllum nodosum 45 mg - Kelp is likely also included for iodine.
No wonder your body is confused! Herbs to stimulate cortisol, reduce cortisol and provoke your thyroid. I'm confused just reading the formula. Unfortunately it is typical.
If you have low cortisol, why would you want to take a formula that contains an ingredient that will further lower it? If you have high cortisol, why would you want to take an ingredient that will raise it (all while the adaptogens cancel everything out??)?
This is not to say those ingredients are bad, per se. Just how do you know what is doing what?
Have you had a saliva cortisol test to see what your levels actually are doing throughout the day?
