Hi I'm posting my latest bloods just for an opinion. Last time in Jan my b12 was 666 pmol and id taken a weeks break off supplements. This time I continued to suppliment until the day of the test then took it after the test.
I've switched to hydroxycobalamin sublinguals (500mcg daily) now and do feel an improvement even though my levels have dropped. I do still have very tired eyes but definitely more energy and can stand up without my heart pounding and seeing black.
Thyroid Uk forum say my thyroid levels are spot on thankfully 😅
Folate was 14.73 in January and ferritin was 219.2 (same reference range as above)
