I have some sort of connective tissue disorder and am currently going very hard trying to fix my thyroid, promising results but to be seen what happens. But in my experience stock, mainly thick home made beef stock, has been the single best thing for me by far. Another and I was surprised by this recently is Vitamin E, I have been ingesting tons of it from food sources and been noticing huge effects instantly.
I think people in this thread may be having the same kinds of responses to changes in health. If you try to 'build yourself up' like with thyroid or something, you'll start doing better but then fall apart soon after. I'm currently going in extremely hard trying to max out basically every nutrient I can think of while eating thyroid and it seems like it may be working.
But does anyone here deal with extremely low amounts of energy and have any kind of solution? I can never really figure out what causes low energy and what helps me raise it occasionally.
