So i just got my lab work back and my Free T3, Cortisol and DHEA.  My doctor wants to put me on supplements, but i'm not too keen on the idea.  Has anyone increased these without having to take supplementation?  What are hacks that can help increase these?

You could take DHEA supplements, which is a precursor to cortisol. However, you're probably better off increasing saturated fats, for example from grassfed butter, coconut oil, lard or tallow, which is the substrate used to make hormones.  Egg yolks are also important, as are minerals such as zinc, potassium, magnesium, selenium, and iodine. 

(But be careful with the last two if you have tyroid antibodies as the treatments for Graves and Hashimotos - if you have one of these, are going to require you to stay away from these for a while.)

In terms of adrenal health, you'll want to ensure you have Vitamin C, and full spectrum salts.  Typically you'll want to drink a teaspoon of sea salt in water in the morning.

You can also take DGL or licorice which will prevent your existing cortisol from being broken down too quickly, but this is not a long term solution.  What this will do is give your adrenals a break for a while by not having to create as much cortisol.


Are your rT3 levels high?  Do you have normal T4 levels?  Did you by some change go on a zero carb diet, or on a VLC diet and also do intermittent fasting or alternate day fasting? Going very low carb will tend to turn off your thyroid and will cause high rT3/rT4 and low T3 levels.  One of the biggest mistakes folks make is to go very low carb and also do some form of fasting at the same time (I did this too and got in trouble in a similar way.)

Thank you for taking the time to answer.    Yes I will be supplementing with DHEA per my doctor's prescription and recommendation. I've been doing low carb for a while.  I did have carbs daily for a little bit mainly for dinner bit I didn't seem to lose weight so in September I started the Altshift protocol by Jason Seib, which  has days with low carb, high fat and some days with high carb low fat. Before this protocol I was afraid of fat and did not consume enough of it.  Ever since then i've lost fat and feel better.  More alert, but i do have some nights where I dont sleep well.  This could be do to the fact that i'm deficient in Vitamin B3 which I will start this week.

My T4 levels are normal.  I'm not sure about my rt3 and rt4 but i believe they are normal.

Thanks again,
