I keep reading that anything classed as more intense than 'moderate' exercise depletes T3 at a rate of knots; for euthyroid folks this isn't a problem as the feedback loop kicks in and their bodies produce more to compensate but for those of us reliant on taking hormones by mouth this isn't an option. (And I can attest that since taking up running my thyroid levels have been all over the shop, but mostly down.)
Therefore on days when I go running is it feasible to take just that little bit more hormone (either T3 alone or more levo) to cover it, or would I need an increased dose every day? Has anybody tried this? Giving up running isn't an option I'd like to consider as it's done wonders for my mental health and I'd like to come off the lithium sometime in the next year.
