Hello everyone,
I am 35 years old, female with Hashimoto's. I take 150mcg levothyroxine and 25mcg liothyronine. I follow a strictly gluten, dairy and egg free diet and mostly avoid soy except for lecithins and tamari sauce if I have sushi. I take my levo before bed, 2 hours after food. I take my first dose of T3 when I wake up, 30 mins before food and a second dose around 3–5pm but sometimes later depending on when I have eaten (but I always take it 2 hours after food and 30 mins before food).
I had my first blood test in a year last week and my T4 and T3 are both significantly lower than a year ago.
Latest T4: 45.4% through range
One year ago T4 was: 83% through range
Latest T3: 54% through range
One year ago T3 was: 114% through range
In fact, my T3 is back at the level it was when I was on levothyroxine only and feeling really bad. I felt my best when my T3 was at the top of the range or even a bit over range. I've been having thyroid symptoms for the past 4 or 5 months so I'm not that surprised. I've gained about 6–7kg (was 66kg a year ago, now 72–73kg), I'm constantly hungry and overeating, depressed (to the point of suicidal ideation some days), anxious, night sweats, struggling to recover from exercise, irritable, moody, angry, unable to cope with stress and generally just feeling not great.
I have all the supplements I am supposed to take but I don't take them consistently anymore however more recently I have been taking them more often. I take them away from my thyroid meds as I know that can affect absorption.
B vitamin complex (Thorne Basic B)
Ferrous fumarate (I take 410 mg when I remember to take it)
Vitamin D3 + K2 liquid
Magnesium bisglycinate
Selenium
Zinc picolinate
Omega 3 fish oil
My last dose of B complex was Monday and I had my blood test on Friday so I don't know if this had an effect, I know biotin supplements should be stopped 7 days before but unfortunately wasn't able to stick to this on this occasion. My blood test was at 9am, fasted. I skipped my dose of levothyroxine the night before, and took it after my blood test, so my last dose before the test was two nights before. I took my second dose of liothyronine about 12 hours before my blood test. These are the timings I follow for every blood test so they are a consistent comparison to each other.
Here are my latest results:
Serum TSH: <0.01
Serum T4: 15.9 (10.0–23.0)
Serum T3: 5.1 (3.10–6.80)
Serum folate: 7.6 (3.10–20.50)
Serum ferritin: 74 (22–275)
Serum B12: 309 (187.00–883.0)
Serum vitamin D: 93
RBC: 4.28x10^12 (3.95–5.1510)
MCV: 91.0 (80–100)
A year ago (when I felt well and weighed 66kg) they were:
Serum TSH: 0.02 (0.27–4.2)
Serum T4: 18.3 (12.0–22.0) (different range)
Serum T3: 7.3 (3.10–6.80)
Serum folate: 8.54 (2.5–19.50) (different range)
Serum ferritin: 48.0
Serum B12: 396.7 (180.0–900.0) (different range)
Serum vitamin D: 159
RBC: 3.87x10^12 (3.80–5.30) (different range)
MCV: 93.0 (83–100) (different range)
I'm currently abroad with an abundant supply of liothyronine 50mcg tabs and levothyroxine in 100mcg and 50mcg. I won't be returning to the UK for at least one month so this is what I have to work with. What should I increase my doses of each by? I'm thinking of adding a third dose of liothyronine before bed of 12.5mcg so I'm taking a total of 37.5mcg and 25mcg of levothyroxine so I'm taking 175mcg. Would appreciate advice on this. Thank you so much!
