    The Thyroid Factory (Possible Series?)

    This is probably too basic for most people on the forum. But I made it after talking to friends and family about their thyroid bloodwork, so maybe it'll be helpful to yours. And I might do some more advanced ones with time.

    Biotin Can Actually Raise T4 And Lower TSH

    A few users ( @aguilaroja ) posted recent case studies showing that biotin in doses as "low" as 10mg daily can interfere with lab test results and produce false positives for a number of conditions. Perhaps the most widely publicized interference is related to thyroid lab tests. Several people...

    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...

    "Normal" TSH Above 2 As A Cause Of Unexplained Infertility

    As most of the people on this forum know, Peat has spoken many times about the optimal values of TSH and has said that its value should be as close to 0 as possible. I posted a study some time ago showing that "normal" TSH levels above 2 are associated with a number of health issues that baffle...

    Biotin Can Distort Thyroid Lab Testing

    High dose biotin supplements can falsely elevate TSH or other thyroid lab tests. @Koveras discussed this in March, but maybe a separate post can emphasize the concern. Confusing Blood Tests - High FT3 And FT4 And High TSH This is ONLY a caution about interpreting thyroid LAB tests with recent...

    Glycine Lowers Tsh

    This study adds to the evidence that glycine is pro-thyroid and thus anti-stress. A single relatively low (human equivalent) dose of 600mg - 1,500mg blunted the increase of TSH due to stress. Notably, the low HED dose of ~7mg/kg was the most effective, which means 500mg - 700mg is all that is...

    Cyproheptadine Lowers TSH

    Given that cyproheptadine also increases plasma levels of T4, it may be an option for hypothyroid people who cannot tolerate thyroid hormone or do not ant to take it. http://www.ncbi.nlm.nih.gov/pubmed/10437145 "...RESULTS: Cyp 2.3 mg.kg-1 ig for 10 d decreased serum thyroid stimulating...

    Methylene Blue (MB) Mimics Thyroid - Boosts T4 , Lowers TSH

    These studies show that MB increased the levels of T4 in the blood, and lowered TSH. This may explain some of the beneficial effects of MB on hypothyroid people. http://www.ncbi.nlm.nih.gov/pubmed/8624735 "...Surprisingly, blood thyroxine levels increased consistently in rats after MB...

    Optimal Levels Of TSH Are Much Lower Than Official Guidelines

    Most doctors and especially endos would not touch thyroid function unless TSH exceeds 5. However, as per Peat's advice, this study in HEALTHY people concluded that healthy TSH levels are likely below 2 and anything above that may be indicative of a metabolic problem, especially elevated...

    TSH associated with insulin resistance even in euthyroid people

    The study looked at obese but non-diabetic people who had average TSH levels of 2.7 - a level Peat would consider indicative of hypothyroidism, but considered normal by medical standards. In men, the TSH levels were predictive of impaired insulin sensitivity so I think this is yet another...

    TSH upregulates cholesterol synthesis

    After years (maybe decades) of denial by official medicine that thyroid status affects cholesterol levels, this study is lighting up the blogosphere. It looks like the connection between high TSH and high cholesterol is re-established and it validates some of the ideas and methods of Broda...

    Caffeine Acts Like Supplemental Thyroid - It Suppresses TSH / GH

    Based on Ray's writings about caffeine being a surrogate for thyroid hormone, this study showed that caffeine suppresses both TSH and growth hormone (GH). Ingestion of Cynoplus or other equivalent product containing both T4 and T3 has been shown to have the same effects. The effective human...
