Yeah but orally, only about 10% actually gets into your system. Do you do sublingual? It is more effective. It is good that they checked it. Not all docs will. Hope it is helping.
No sublingual.
I am vegetarian, and I had Sciatica nerve pain last year, my sis who is a doctor asked to get blood work done and found very low B12 and Vit D was just 33 (very low) . now take D3 also.
