Levothyroxine and vitamin - timings

Morning. I have taken my first dose of Levothyroxine this morning. I have a recollection of being told / reading about timing of taking other medication being important but can’t find it to refresh myself.

Would someone be able to tell me when I am best to take my vitamins..? B12, B complex and D as well as selenium are on the cards rather than anything more exciting 😀

Thank you.

I like to take B vitamins in a morning, at least 2 hours away from levothyroxine

With iron supplements there should ideally be a 2 hour gap between these and any other supplement and a 4 hour gap with thyroid medication.

Vitamin D is fat soluble, so ideally with fattiest meal of the day.

You need to be careful not to go above range with selenium. Studies have shown that those supplementing high doses (400ug daily) may have toxic levels. As such, it’s recommended to take no more than 100ug daily as a supplement (or 200ug if you have active Thyroid Eye Disease) or eat 1-2 Brazil nuts (as each nut may contain 50-90ug selenium dependent upon soil type).

only make one change or add one supplement at a time, otherwise can’t work out what’s helping

if vitamin D is mouth spray you can take after breakfast….

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

It’s trial and error what dose we need, with thyroid issues we frequently need higher dose than average

And a separate magnesium supplement best afternoon or evening at least 4 hours away from Levo

Web links about taking important cofactors - magnesium and Vit K2-MK7

Magnesium best taken in the afternoon or evening, but must be four hours away from levothyroxine

Many people find it more convenient, possibly more effective to take Levo at bedtime

No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.

Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away

(Time gap doesn't apply to Vitamin D mouth spray)

If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test

If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal

Best test selenium

Might only need it 2-3 times a week
