Health

First off, I am 71 yo and have been on levo since my 30's. About 20 years ago liothyronine was added (.5 mcg/day). I go to an NMD who specializes in hrt and have had yearly blood work. For the past 6 years or so my blood work has been wonky. Sometimes its Hashi, sometimes its hypo, sometimes its hyper, and then recently its been both hypo and hyper at the same time. When I reviewed several past years of my blood work against when I started taking CBD oil I noticed that the dose for levo was reduced as my cbd oil intake was increased. I began to wonder if there was a connection.

In March of this year I decided to do a self test. I had all the blood work done for thyroid testing and then took myself off of all thyroid medication. Since levo has a half life of 33 days I waited seven weeks to be retested. That test showed a high TSH with all other levels wnl. Since the only way to reduce TSH is with levo I resumed taking it but without the lio. In a few weeks I will go get another test for all thyroid levels to make sure the other levels are still wnl while my TSH is lowering.

My advice is to educate yourself on how to read the bloodwork. My further advice is to know that someone can have Hashi without having thyroditis. Though one usually occurs with the other they are mutually exclusive. My final advice is to take selenium, zinc and Vit B and D everyday. Don't take added selenium if you are in a selenium rich area, however.

The question I haven't found an answer to is this: Since levo has a half life of 33 days doesn't that mean that if, on day one if you take 50 mcg, on day 2 and beyond your body is actually taking in more levo than the 50 mcg/day prescribed?

I hope this helps.
