The “normal” 25-hydroxyvitamin D lab range is between 20-56 ng/ml. As you can see in the chart below, this conventional range is really a sign of deficiency, and is too broad to be ideal. In fact, your vitamin D level shouldneverbe below 32 ng/ml, and any levels below 20 ng/...
increasing the production of active D3 by the kidneys during times of deficiency and insufficiency, so a blood test for 1,25(OH)D may appear normal or elevated even when your actual levels of vitamin D are low. However, in some disorders of calcium metabolism, the 1,25(OH)D test may ...
Vitamin D enhances the absorption of dietary calcium by 30%-40% and phosphorus by 80%. Without it, only 10%-15% of calcium and 60% of phosphorus is absorbed. Vitamin D promotes calcium absorption in the gut and maintains blood calcium levels to enable normal mineralization of bone and prev...

Normal blood levels of vitamin D (calcidiol, 25 OHD) are50-125 nmol/L (20-50 ng/mL). Abnormal levels[1]: Levels below 30 nmol/L are associated with rickets in infants and osteomalacia in adults. Levels 30-50 nmol/L are considered inadequate for bone and general health. ...
vitamin D insufficiency and normal participants, respectively. This difference remained significant after adjustment for demographic, behavioral, and clinical risk factors (P= 0.026). There was no correlation between 25-hydroxyvitamin D levels and CD34+ cell counts, even after covariate adjustment (P= ...

the limited genetic variants of absolute vitamin A and vitamin B9 levels impeded sensitivity analyses. However, these genetic instruments were derived from the largest GWAS available, and results were consistent when vitamin A was analyzed using the absolute blood level and metabolite levels. Third, ...
All of these serum levels are within the normal expected ranges of 30 to 100 ng/ml. Minimize the amount of vitamin D2 that you are getting. Sources may be in your multiple vitamin/mineral and may be through the amount of sun (UV light) exposed fungus like mushrooms. As you know, ...
