I'm on 75mg Levothyroxine and 10mg liothyrine, is it best I still take it in morning with water and vitamin C wait an hr before eating and can I split T3 and take 5mg later in evening or day, does anyone else do this? Will I still need test in 6-8weeks to optimise?

Firstly why are you taking vit C with Levo and T3? Levo should be taken on its own on an empty stomach an hour before food/caffeine drinks.
T3 is better for some taken as a split dose. Take second dose late afternoon or bedtime to help sleep.
Yes testing should be every 6-8 weeks for dose adjustment. You will likely need private blood tests as NHS rarely tests FT3.
Vit C actually improves absorption of levo ~i think ?
Not seen anyone here recommend it, never heard of it.
there's lots of reliable research showing the effect eg pubmed.ncbi.nlm.nih.gov/246... it's probably not mentioned often on here to avoid muddying the waters re. not taking vitamin supplements etc with Levo . Vit C seems to be one of the few things that are known to actually improve absorption.
Many people have said vitamin C helps with absorption of Levothyroxine and if NHS are prescribing Liothyrine they should be testing it
I just did a google about the vit C thing. Turns out it can be a thing although I don't think it's commonly done.
Completely agree about NHS prescribing then testing FT3. They are so overwhelmingly obsessed with TSH though that they frequently still consider FT3 irrelevant. If you are receiving T3 on the NHS you might find that your Endo insists on your TSH remaining within the normal range which doesn't work for many.
Many members split T3 into 2 or 3 smaller doses spread across the day
Many people find small 5mcg dose T3 at bedtime improves sleep
If on just 2 x 5mcg ….taking waking and bedtime
Or perhaps waking mid- late afternoon if it keeps you awake
If eventually on 3 x 5mcg ….waking, mid afternoon and bedtime
Day before blood test always split T3
(even if don’t do so normally)
Last 5mcg dose Approx 8-12 hours before test
Last dose levothyroxine 24 hours before test
