Re: Is Nature-Throid conversion chart accurate?
The "official" charts equate .1 mg Synthroid to 1 grain of the natural meds, but that's only in an ideal world. Differences in digestion, absorption, and conversion mean that 1 grain is more closely equivalent to only .075 mg of Synthroid for most people. In short, 1 grain is worth between .074 and .1 Synthroid.
It's important to understand that palpatations, while often frightening, aren't necessarily dangerous. Unless you're elderly or have a chronic heart condition, your body will eventually adapt to that T3 and the palps will disappear. That adaptation period generally lasts only a week or two per dose. Changing your dose every other day isn't the best idea and won't get you where you need to be as soon as you want to be there. You should pick a dose - 1/2 grain is a good start - and stay there for at least a month before raising it again.
Check with your doc about the palpatations to be sure.
