TSH of 0.05 can be alarming. Usually, while on Naturethroid, it is in a 0.02-0.03 range, closer to 0.1. The trouble is that your doctor did not test the Free T3. You really need to know that level. While the FT4 is not terribly high/low, the FT3 could be too high. A slight decrease in the dose could fix that. Also, when taking an NDT, because it contains T4 and T3 hormone, it is best to test the levels 8 to 12 hours after taking the dose. Another factor is that most people split the dose into AM and PM. They go for the blood work 8 hours after taking the AM dose, before the PM dose. This helps to get a more accurate level of FT3 (the T3 in the NDT is short-acting and could show up as a higher level if the blood work is too close to when you took the pill).
