Hello ElSneak,
I know what being tired al the time means. It is often a result of a not well functioning thyroid. You could use some more iodine. But watch out, it could be that you also have weak adrenals, because these two conditions go often together.
To give myself some extra energy i use celtic sea salt and i use a adrenal grandular (

Good luck!
