Let me answer with my second thought first because I read the note from the woman with "Zeal". Then I looked on the "Zeal for Life" website at the list of ingredients. Please do not willy nilly start taking pills and potions. Amongst the ingredients of this little suggestion is ashwaganda. Please check the serious contraindications for taking this product:
This little herb is NOT for someone who is having problems with either liver or thyroid.
Since you say you are obese, it would seem that would be the first thing to address and that would mean a total change in how you eat and live. Are you up to it? Heck, you just went through cancer tortures, er, treats, and you are capable of just about anything once you put your mind to it.
I don't know a thing about synthoid (isn't it for thyroid?) but an improper dosage can make you somewhat sick and cause you to gain weight and lose energy.. Finding a proper dosage is trial and error. There are natural pills to correct hypothyroidism. Why not ask your doc about them?
Besides a drastic change in diet (much more uncooked greens and fruit and some particular ones at that), you really need to find out the cause of these elevated liver enzymes. It is not normal. Taking milk thistle and NACL will mask the problem but not get to the root cause even though (I believe) milk thistle is liver protective.
About 10 months after cancer being made kaput and 3 months after starting a regimen meant to strengthen me, I reached a plateau which was far below what I considered normal. I went back to the docs and had to fight and argue in order to get more blood tests which eventually revealed I had hcv. I thought about all the blood which was taken while I was under the doctor's care and asked how it was possible that either they had missed it or had missed telling me about the problem. The response was stupefying. "We thought you already knew."
Be insistent and find out what is troubling your liver.
BTW, I am a raw foodie. I believe how I eat helped to save my pitiable life.
Very best wishes for recovered good health.
