Jules, it may be helpful to research what vitamins/minerals etc. Covid patients are low on or what has helped them recover. For example, a few different websites said those with severe Covid or long Covid were low in either iron, B12, or Glutathione. Also there was a girl from the UK that had long Covid and she had an iron IV which cleared up her symptoms but I believe she was low on iron to begin with. Please do your own research and be sure and check with your doctor before adding any new supplement to your daily diet.
