My cortisol levels have been in the normal range for some time but I wanted to lower further. In February did a blood test and saw my baseline result.
Earlier in the month I took OFN cortisol supplement and most recently Glaxon for stress. Did another blood test the other day my cortisol almost the same wtf
Both blood tests take morning with fasting.. not convinced by them .. will try cortibloc soon
Anyone had similar experience??
So I know I can be harsh on you at times, but I think it is cool you actually tried to get this stuff measured to see if an actual benefit was noticed!
First I'd ask why you would want to lower cortisol if it is already in normal ranges? We want cortisol and we want a healthy amount of it being used (we want to secrete it for specific acute situations to do its job then for it to back off when needed, not become a chronic issue).
Was this product Serenity that you used? I am going to assume so for next little bit.
I'd keep in mind that it seems to be more of an adaptogenic cortisol product.
Ashwagandha tends to have a more "leveling" effect, so if cortisol wasn't too high it wouldn't necessarily work to keep lowering it. But benefits in other regards may still be beneficial for some (Ash has other effects on hormones, performance, anxiety, etc. that may not be directly related to cortisol).
Magnolia Bark also doesn't have a ton of clinical studies and again seems to be more in line with as a product that helps with typical symptoms or issues of people with high cortisol (helps improve anxiety, stress, and sleep), but that may not mean it is directly lowering cortisol.
Phosphatidylserine also seems to be shown to lower exercised induced cortisol spikes, so I am unsure if that would show changes in daily levels (and the research for this is mixed).
Now don't take that as me saying that it works and you are wrong, I just think that a direct cortisol test, especially when you are in normal ranges, may be a bad proxy for the effectiveness of that type of product.
Now something like Cortibloc or others that work on a more direct mechanism may lower cortisol, but again I'd caution that unless you really need it (I think too many people on here use cortisol products when there isn't a huge need anyways, but that is a topic for another time).
I hope you get something from my run down here and sorry for not being brief. I know we have disagreed in the past, but I figured it was worth typing some sort of response for you as you seemed to have a solid question and reasoning and then just had people offer you their normal suggestions (just try this!) instead of actually offering input on your actual question.
