Not a woman

If you can get it from your primary care doctor or from a service like this, a blood test can be SO helpful to make sure you’re not overdoing it on a vitamin you don’t need / underdoing it on a vitamin where you have a real deficiency. I ended up getting prescribed a vitamin b nasal spray because even though I was taking vitamin b pills every day, the vitamin deficiency was so bad we needed the big guns. I never would have suspected!
