I was taking Tyromax and wasn’t getting the temps needed- I tried for about 8 months and eventually my reverse T3 just started getting higher and higher. So, I’ve switched to T3 solo- oral temps regaularly at 37 but armpit stays...

    Nose bleeds from T3? Help!

    What could be the reason I am getting nose bleeds after recently starting T3 supplementation? Is this a sign that I'm taking too much or that I need to take T4 with it as well?

    Day 7 of thyroid supplementation, few questions

    Hello all, I have been taking T4/T3 (2:1 ratio) for seven days now, slowly titrating up. I began with 3 mcg T3 and 6 mcg T4 once daily and now am up to triple both doses on day 7 (too fast?), split into three doses throughout my day. I have upped my calories and I am including as many nutrients...

    Levothyroxine (T4) Monotherapy Often Ineffective For Hypothyroidism

    As most of my readers know, the currently approved therapy for hypothyroidism is levothyroxine (T4). While technically T3 and combined T4/T3 therapy are also approved by FDA, the former is only used in severe cases of myxedema and the latter is considered obsolete and a remnant of the days when...

    It does not get much better than what this study found. More than 2/3 of mildly depressed patients and basically all moderately and severely depressed ones has low T3 levels. TSH was elevated in almost 55% of the patients. As the study says, this widespread prevalence of sub-clinical...

    Effect Of Vitamin C On The Absorption Of Levothyroxine

    The following study with Vitamin C and Hypothyroid persons taking Levothyroxine is interesting. Coupled with the study posted about Vitamin A in 25,000IU doses daily decreasing TSH, it makes me wonder why a person has to be on thyroid meds. Or, why begin with thyroid meds or increase thyroid...
