I have had two vitamin D readings, one in Sept last year (60) and one early this month (68). I am taking Vitabiotics brand at the moment but for reasons I don’t yet, they now give me acid reflux (along with other foods and possible some brands ofT4).
If I am suffering acid reflux after taking them, could this be making the vitamin D levels low? Also, more importantly, is this low vitamin D causing poor conversion of T4 to T3?
Thank you for any possible advice on this.
What strength are they? Must admit it's not a brand that I rate as they do add many excipients the strongest they do seems to be 3000iu which probably isn't enough anyway and doesn't contain K2.... I'd suggest swapping to a sublingual like Nature Provides

Thank you very much for your reply and advice. I am looking at an alternative due to the fillers but can the low vitamin D affect conversion of T4?
Yes, it is one of the key factors along will iron, B12 and folate
acid reflux is hypo symptom
How much levothyroxine are you taking
What were most recent TSH, Ft4 and Ft3 results
Suggest you try different vitamin D
Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.
There’s a version made that also contains vitamin K2 Mk7.
One spray = 1000iu
amazon.co.uk/BetterYou-Dlux...
It’s trial and error what dose we need, with thyroid issues we frequently need higher dose than average
Suggest you try 2000-3000iu daily
Retest in 2-3 months
Aim for vitamin D at least 80-100nmol
Test twice yearly when supplementing
Can test via NHS private testing service
What are folate, B12 and ferritin results
What other supplements are you taking
Thank you very much. I am holding out for a thyroid panel test at the GP (two weeks to go) as I have moved it up and down over the last few months prior to this.. I do have T3 and don’t want to add this without knowing my levels at 100 mcg (I have been on this over a year). I have had very helpful advice about my T3 from this forum but I feel I need to know how my levels are on the T4 (by staying on 100 mcg for 8 weeks).
It has been gruelling and a long long time spent being unwell because my GP refused a blood test in August last year so I tried putting T4 up and then down and got in a mess. I have had private tests but I like to stay with NHS ones as this is how I tracked my levels in the past and private results are differing and confusing me. I really don’t know if private results are more accurate or the NHS ones. It is the T4 that differs the most and is over range (always) on private but within range on NHS testing.
B12, folate and ferritin have all been okay. I take vitamin D only at the moment. The mouth spray gave me very bad acid reflux so I couldn’t take that unfortunately but I am trying to source one without fillers as TiggerMe advised.
Thank again

Private tests are often processed at same laboratory as NHS
Timing of testing is crucial. ….all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
And many people find different brands of levothyroxine are not interchangeable
Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine
When comparing different test results from different labs with different ranges ….use the % calculator
Eg
NHS test
Ft4 16 (9-19)
Ft4 is 70% through range
Private test
Ft4 19 (12-22)
Ft4 is 70% through range
Correcting low vitamin levels can reveal how hypo you are …..making hypo symptoms more likely
So correcting low vitamin D is necessary
B12, folate and ferritin have all been okay.
Can you add actual results
Vitamin D tablets or gels need to be at least 4 hours away from Levo
Best taken with high fat meal to improve absorption. So that’s usually evening meal
Thanks a lot. I will try this when I receive the new ones I have ordered.
Looking at previous posts
You recently started on T3 alongside Levo
How much Levo are you now taking
Dropping from 100mcg to 50mcg was huge reduction
Have you retested since starting
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
T3 ….day before test split T3 as 2 or 3 smaller doses spread through the day, with last dose approximately 8-12 hours before test
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
