Unfortunately, this will not help the bulk of people who are suffering with these symptoms. This is largely related to the fact that most people can’t effectively convert the pure T4 in the synthetic thyroid preparations to T3.
For the record..one reason I'm upset (and say about F'in time) with the Medical System is I have had a slow metabolism and a multitude of hypothyroidism type stmptoms for years (a long time)....including low morning body temperature (94.1 F at it's lowest)
Now, just in the last year..although I had controlled most of these symptoms with kelp and desicated thyroid, my TSH (ultrasensitve) just hit 5.48 on the scale of .4 to 5.20 mU/L..and my VAT (Visceral Adipose Tissue), although low by most standards, was at an all time high following my last bulk (Dec)
Mrs. Pain who has a geneticaly linked hypothyrodism, and was prescibed T4 (synthyroid) for years...was also controlling her condition "Naturally" also...her TSH was just 3.49....on the same scale...but our Doctor was aware of recent developments and felt this was Hypo as well!
So, my advice.......get a physical, and get a TSH test if you aren't sure. Try Natural methods if you are so inclined first.......but know your options.
