For once I think I can offer something concrete to help somebody.
I am hypo-thyroid and have been on med (a T4 called Lavoxil) since Jan 01.
T3 must be converted by the liver into T3. The brain can't use it properly until this is done.
I augment my med by taking Selenium.
If your H has a lot of silver almalamate fillings then he would definitely benefit by taking Selenium With his med.
Have him store the med in the frig. If the inside of the bottle developes a fine powdery coating then it is no longer optimum.
If you want to really help him become healthy then go after his nutrition.
Calcium leaches the med from the system so it is important that he not have any calcium for 4 hours after taking the med. Fiber isn't a good idea either because the med will bind to it and flush from the system faster.
Example: If he doses every a.m. at 5:30 then his Break fast should be anything but dairy and fiber.
Hypos need that protein so encourage that.
Calcium, magnesium and zinc are needed. The calcium is best taken 3 times a day.
Iron is needed. Here's the kicker. If you med at 5:30 a then the iron should be added exactly opposite (5:30p) so as to optimize the body's use of the med.
Oh, and the calcium and iron shouldn't be taken together so you have to choreograph that a well.
Tiel, it took me 8 months of rigorous health maitenance to get to a healthy TSH (the closer to Zero the better your hormonal health!).
Booze is bad cause it taxes the liver which can't process the T4 optimally. Hypos who choose to drink alcohol should ingest a lot of water after the booze.
There's so much that can be done here.
Walking is a great way of getting the T3 (which either has to be converted from the T4 or prehaps is a T3 called Cyclomel which some people take in addition to the T4) into the brain.
Yoga is great also.
The magnificent brain, center of all perceptions.
You can go at this supplementing via the various vitamins or through what you prepare and put on the table.
Your H is going to start feeling better. It is nice to know that someone understands and supports you during the healing process. Lucky man.
