Hi Ellibee, I'm sorry your post was missed. Bit late answering now but I hope you are getting on OK with the thyroid medication.
The timing of your dosing & food intake should be fine & by coincidence matches mine. The standard advice is to take Thyroxine at least 30 mins - 1hr before any food or drink, other than the large glass of water you take the meds with. I routinely leave at least an hour before eating & only very occasionally resort to 30 mins in unusual circs.
The emphasis on separation is to avoid possible interaction with substances in food & drink that may impair absorption. So an initial 30-60 min fasting period should allow sufficient time for your meds to be absorbed, but their efficacy could still be compromised if you are in the habit of taking certain supplements with breakfast. There are a couple of straightforward links & extracts here (by straightforward I mean they don't detail the long list of possibly interacting medications some articles include) . . .
https://www.nhs.uk/medicines/levothyroxine/"4. How and when to take levothyroxine
Take levothyroxine once a day in the morning, ideally at least 30 minutes before having breakfast or a drink containing caffeine, like tea or coffee.
Food and caffeinated drinks can both stop your body taking in levothyroxine properly so it does not work as well."
https://www.btf-thyroid.org/levothyroxine"How should I take levothyroxine?
Levothyroxine is best taken in the morning, with water, on an empty stomach, at least half an hour before eating and drinking anything. It is also best taken at least four hours apart from calcium, iron, cholesterol-lowering drugs (cholestyramine, colestipol), and multivitamin tablets, as these can also decrease absorption. Grapefruit also interferes with the absorption of levothyroxine. There are several other drugs that interact with levothyroxine. Always check with your doctor or pharmacy if you are on any other prescription or over-the-counter medication."
