@raghav , do you take TH to treat hypothyroidism?
T3 should be taken three times a day, this is what showed up in this study by Pr Jonklaas (2016) (below)
Her results (table A) match pretty well with what I noticed when taking T3 with non genomic effect starting an hour later and ended 9 hours after intake.
.........
in this
study where they used T3 or T4 with
three intakes per day, they found:
"The dose of l-T3 was 0.57 ± 0.08 μg/kg · d, whereas the l-T4 was 1.68 ± 0.33 μg/kg · d with a microgram/microgram l-T3 to l-T4 ratio of 0.34 ± 0.05"
which means the dose to achieve the same TSH result, was T4 daydose = T3 daydose/0.34= 3 x T3 daydose, which is the same
@Hip quoted.
By the way this study found that the effect of three daily doses of T3 has much more effects on many metabolic parameters (lipid metabolism) than T4.
I noticed that Heart rates were not different (about 80 BPM at rest)
