Since July early 20s DD has had glandular fever, covid (in past 3 weeks), has now gone back to uni and seems to be ill again with cold symptoms. She’d recovered from covid about 2 weeks ago and it wasn’t too bad a bout. She had bloods taken about a month ago to check liver function after GF and all was well - had full blood count, etc. Has been low iron before but this wasn’t flagged in latest set.
Anything I can recommend she takes to boost immunity. She just sent me a pic and she looks pretty run down - skin not great etc.
