Hi, I'm due another blood test soon, GP for TSH, and Medichecks for the rest. I know not to take Levothyroxine for 24hrs before test. I'm also taking Magnesium Malate, Vitamin D3, Vitamin K2 MK-7 and L-Selenomethionine. Should I stop these before testing or continue? Thanks in advance.

You can continue with them but on the day of your test take them after the blood draw.
The only supplement you would need to stop before any blood test is biotin or a B Complex containing Biotin or if testing iron then no iron supplements in the week before the test.
