I did an e-comsult asking for a blood test for two things. Firstly I have been taking OTC vitamin D as I read this may be beneficial if you catch Covid (although I have also read this is debunked). I wanted my vitamin D level checked so I know whether or not to continue with this.
And secondly my hair has become very dry so I wondered if I am deficient in anything, or if it ok to try OTC biotin or zinc.
The surgery replied to say it's up to me if I want to continue with vitamin D supplements or not as they are OTC, and that I should talk to a pharmacist about my dry hair.
So no blood tests for me.
