One of the most common signs of primary immunodeficiency is having infections that are more frequent, longer lasting or harder to treat than are the infections of someone with a typical immune system. You also may get infections that a person with a healthy immune system likely wouldn't get.
What Vitamins Should You Avoid Taking Together?
You should primarily get vitamins from a varied diet, but common daily supplements often include Vitamin D (for bones/immune), B vitamins (for energy/metabolism, especially B12 for vegans), Vitamin C (immune/antioxidant), and sometimes Iron (energy/red blood cells), Magnesium (muscle/nerve), or Calcium, depending on your diet and lifestyle, with multivitamins helping fill gaps but consult a doctor to avoid overconsumption.
