Dr. Manisha Arora, Head of Internal Medicine at CK Birla Hospital in Delhi (India) - said that vitamin D holds an important position in overall health, it helps maintain bone health, supports the immune system and regulates various functions of the body.
Typically, optimal blood levels of vitamin D are measured as 25-hydroxyvitamin D, which is the form of vitamin D used by the body and is easily measured in a blood test, according to Dr. Arora.
Optimal vitamin D levels can vary depending on individual needs, but health organizations generally recommend the following levels:
Optimal vitamin D concentration: About 20 - 40 ng/mL (nanograms/milliliter)
Vitamin D deficiency: Less than 20 ng/mL (50 nmol/L).
Excess vitamin D levels: Above 100 ng/mL (250 nmol/L), this can cause health problems such as vitamin D toxicity.
“Low vitamin D levels indicate a serious deficiency of this essential nutrient, which affects many functions of the body, especially in maintaining bone health,” Dr. Arora emphasizes.
When levels drop, the body cannot absorb calcium effectively, reducing bone density and increasing the risk of fractures and other health problems. You need immediate intervention in cases of severe deficiency.”
Vitamin D is also essential for a healthy immune system. Vitamin D deficiency can weaken your body's defenses, making you more susceptible to infections and potentially leading to autoimmune diseases.
The amount of vitamin D needed may vary depending on age, health status, geographic location (sun exposure), and other factors.
To determine whether the vitamin D level is appropriate and optimal for your health, you should consult your doctor or nutritionist for appropriate intervention.
