Vitamin B deficiency
Is there anyone who got better after supplementing B Vitamins, especially B1?
I ate just before the blood sample, does this effect the values alot?
Also should I be worried about the Vitamin E levels?
I have been taking vitamin D3 supplement for almost a year (fat based Vitamin D3, E, K, A) but D3 Level ist still low ( started at 11ng/ml)
