This article will be a supplement to Danny’s “Demystifying Thyroid Supplementation” article, as I think some of the points could be expanded upon with more detail. As a general rule, I think starting with a “T3 only” supplement is best since triiodothyronine has a shorter half-life than thyroxine and it’s easier to gauge its effect at a specific dose. A thyroid supplement that contains both “t3+t4” is more nuanced and should be approached carefully. If liver function is impaired and it's overburdened with things like endotoxin and estrogen, the conversion of T4 to T3 will suffer and reverse T3 will increase, lowering the metabolism. At night, T4 suppresses the TSH better than T3 and helps to keep the stress hormones down when you’re asleep. Because thyroid supplements are heat sensitive, it is important to find a brand that doesn’t have “dead batches” and is generally active. I personally use cynoplus and cynomel and find dosing them to be more accurate than NDTs (Naturally Desiccated Thyroid). I think it is paramount to make sure you’re consistent with dosing thyroid hormones (using a milligram scale etc.)
