Hi, i got tested low vitamin d and something strange happens when i try to take vitamin d supplement… I started with 1000ui per day and after 3 or 4 days i get muscle cramps and lower back stiffness and joint stiffness especially the ankles. And also i feel almost like i have the flu,
When i stop supplementing all the symptoms disapear in about 2days. I tried many times and its always the same. Im I the only one to react to such a low dose?? Do you have an idea what could cause this? Everything else is fine on my blood test.
Also i have genetic hemochromatosis but it is treated and my ferritin is normal now
Thanks for your time
