hashimotos and supplements

hello all - advice please on supplements - i currently take 200mcg of T4 and 20mcg of t3 (split into 2 doses) - I am about to start B12 loading doses with folate.

I also take HRT and anti depressants and am vitamin D deficient. (Im a bit broken!!)

I take the T4 and T3 at 0630am

Vitamin D and K2 at 1030am

Second T3 dose at 12noon

HRT and anti depressants bedtime

What else would you build into the day and when would you take them?

Thank you

Vitamin D should be taken 4 hours away from Levothyroxine and T3. It's best taken with the fattiest meal of the day as fat aids absorption.

I'm not a fan of shovelling in lots of supplements in unless there are deficiencies but I do think 1,000mcg vitamin C helps boost the immune system. I don't recommend supplementing iron, calcium, vitamin D, or B12 unless blood tests show it is necessary.


Thankyou - sadly my b12 and vitamin d is deficient :0( I have tried taking vitamin d later in the day but it keeps me awake at night and I often find myself in th wide awake club at 3am- any thoughts?



Could you take your 10.30 T3 dose later?


I take vitamin d3 at 1030 - I guess I could take my T3 later than 12 noon?
