I take 5000 units of vitamin D every day because the chemo I had several years ago killed my body’s ability to make it.
I take 5,000 IU daily to manage chronic urticaria (hives). After doing a bunch of research, I ran across a study on using Vit D and it works for me. On occasion, I have to take an antihistamine too, but if I take Vit D first thing in the morning, I’m usually good for the day. If I mow grass or do something where I am getting hives later in the day, another 5K will usually resolve the issue. It’s rather amazing, actually that this works. Vit D is actually a hormone and the more research that is done, the more the realization about how important it is in many processes in our bodies.
