Should I stop using herbal blends before blood tests?

As I shared on someone else’s post, I had what I think may have been COVID some weeks ago. Raised temperature, headache, tight chest, sore throat, swollen glands, loss of taste and smell, diarrhoea, nervy pains in my fingers and toes, extreme exhaustion. I had little appetite for about ten days. One of the things I did to try to help myself was make smoothies, to which I added a Naturya Immunity blend of Wheatgrass, Barleygrass and Camu Camu I got via Amazon.

I’m due to have my next thyroid blood test next Tuesday. This morning, I noticed the nutritional value of this on the back of the packet. It’s pretty high in B vitamins. Since I know I should avoid B vitamins, at least in pill form, for a week before blood tests, do you think I should lay off this too?

I would stop it. It contains Biotin which is the B vitamin that should be stopped, although it's only a very low dose I would err on the side of caution and stop it for a few days.

Thank you! Thought it best to check 🙂

Yes, stop taking them if you want an accurate reading. Also, do not take any thyroid meds that morning before your test.

Thanks for the reminder. Always so much to think about! 🙂

But add magnesium in high does after. I have been doing medical research at oxford and i think long Covid is caused by magnesium depletion. magnesium is involved in the uptake of oxygen from the lungs and 600 or so other reactions. read DINicolantonio in BMJ april 2018. free to read on Google scholar. good luck. julia.

How interesting. I’ve heard of the importance of Vit D and Vit C for COVID/viral recovery but not magnesium. I read that article you referred to also. Fascinating.
