A simple blood test could tell you what vitamins you're lacking, so then you're not getting too much which isn't always a good thing, it can be hard for your body to absorb.
Myself, I'm on 1000-2000 UI Vit D (I Opt'd for drops) and 1000 UI Calcium (I Opt'd for Tums). I take them all in the morning to start off my day. 4laugh
Blood test are far from accurate when testing for deficiency. Your levels can come back fine, but your body is just leaching it from somewhere. Or it takes awhile for an actual deficiency to show up in blood work.
The first and most common Vitamin B12 blood test that is done is actually not for Vitamin B12 at all. When laboratories do a regular Complete Blood Count or ‘CBC’, they further categorize this test by measuring the SIZE of the red blood cell and the NUMBER of them on the portion of the test called an MCV Blood Test. If the cells come back larger than normal with fewer of them, you will be said to have Macrocytic Anemia- which is often CAUSED BY vitamin B12 deficiency. But macrocytic anemia often won’t occur for up to 2 years after the onset of Vitamin B12 deficiency.
