Levothyroxine
Provider review requiredThyroid replacement, dosed to your own TSH
What levothyroxine actually does
Your thyroid is the gland that sets your body's pace. When it slows down, everything else does too — you're tired in a way sleep doesn't fix, cold when nobody else is, foggy, and your weight creeps up without much changing.
This is a replacement for the hormone your thyroid isn't making enough of. It's not a stimulant and it isn't doing anything artificial; it's putting back what should already be there.
The one habit that matters: take it first thing, with water, and wait 30–60 minutes before coffee or breakfast. Food and coffee block a chunk of the absorption. Same time every day beats the perfect time.
Most people feel a difference in 2–4 weeks, and the full effect takes about 6–8 weeks. Your dose is adjusted off a repeat blood test, not off how you feel on any given day — feeling normal again is the destination, and it usually takes a couple of adjustments to land there.
