What about people that are already taking Synthroid and potassium with a prescription.
I know to much can be worse than not enough.Can make your heart race and cause a big problem.
This always concerns me when people post to take this or that because depending on your condition,etc it can kill you. I kept reading about all the benefits of Echinacea so I got some.Had an allergic reaction thus big problems and doctor bills.Lots of things can be dangerous when combined with another medicine or herb.
