Hi, using 1-2 mcg of T3 after dinner (my biggest meal) causes cold feet. Another strange symptom it can cause is strong, fast or slow heart palpitations early in the next morning.

What could be causing this reaction or what does a reaction like this mean? I assume that it's high adrenalin but it does not subside.

@Peatful Hi, I understand, I'm lately eating more but without much difference in stress reduction. I forgot to mention my RT3, it's in the high end, 250 pmol/l (135-320pmol/l reference range).

@Shar_to_the_dae @Peatful My thyroid levels (FT3, FT4, T3, T4) are all within the normal range or slightly on the higher end.

When I say 'eating peaty', I mean consuming unprocessed balanced macro, nutrient-dense foods and maintaining a normal to high calorie intake.

My body temperature is normal/good, with only a slight drop after eating, likely due to the lowering of stress hormones.

Since last year, I've noticed a slight increase in bodily stress over time, but I haven't been able to identify the root cause or get it under control.

I had my blood tested and found that my cortisol levels are high.
I experience the most stress in the morning and evening, but it persists throughout the day, manifesting as palpitations, sweating, hair thinning and loss, and a constant feeling of being "wired." Additionally, I've noticed that my armpits tend to sweat excessively and smell really bad when I'm under more stress, no good sign.

I've tried addressing this by increasing my intake of sugar (having more sweets like chocolate), calories, nutrients, magnesium chloride, potassium, and salt but i didn't do much.
I've also taken K2 MK4 and high-quality ashwagandha extract for a few months, which has helped with slightly general stress reduction, but my baseline stress levels remain too high, making it difficult for me to relax anytime during the day and night.

My diet is on point for the last 3-4 years (peaty and local seasonal eating, I live in Europe) and not much changed.

Does anyone have any idea what my problem could be?
