6 Vital Reasons For Vitamin D Screening

Vitamin D test

Vitamin D to the body is like fuel to an engine. As fuel powers an engine to perform optimally, vitamin D is a key driver for various essential bodily processes. It is a vital nutrient that aids calcium absorption and strengthens bones. From supporting your bone health to ensuring smooth neural pathways and robust immune response, vitamin D emerges as an indispensable nutrient.

The recommended daily allowance of vitamin D for infants up to 1 year is 400 IU. Children above the age of 1 year and adults, including pregnant and breastfeeding women, should take not more than 600 IU of vitamin D. Adults above 70 years of age require 800 IU of Vitamin D[1].

If you are feeling fatigued, depressed, or having pain in bones or muscles, get yourself checked for Vitamin D. Book today!

Here are 6 reasons why vitamin D screening is important:

1. Promotes Bone Health: Vitamin D is essential for calcium absorption, promoting strong and healthy bones. It regulates phosphate and calcium levels in the body, which is required for healthy bone formation[1]. Deficient amounts of vitamin D can cause rickets in children and osteoporosis in adults. Timely screening helps identify deficiencies, reducing the risk of bone-related issues.

2. Supports Immune System: Vitamin D supports the immune system by helping the body defend against infections and illnesses. Insufficient vitamin D levels could elevate the risk of infections and autoimmune diseases like rheumatoid arthritis and type 1 diabetes[2].

3. Uplifts Mood and Mental Health: Vitamin D affects mood regulation and mental health. A strong link was found between low levels of vitamin D and four mood disorders commonly experienced by women: premenstrual syndrome, seasonal affective disorder, non-specified mood disorder, and major depressive disorder. These results suggest a potential biochemical connection between vitamin D and mood-related issues affecting women[3].

4. Improves Cardiovascular Health: Adequate vitamin D levels can help maintain a healthy heart, blood vessels, and blood pressure. Research suggests that vitamin D supplements could potentially aid in reducing blood cholesterol levels and high blood pressure, which are key risk factors for heart disease[4].

5. Aids in Weight Loss: Excess body fat can hinder the skin’s ability to absorb vitamin D effectively. A study group taking vitamin D supplements showed significantly improved weight loss, reduced body fat, and higher vitamin D levels than the other group[5].

6. Pregnancy and Fetal Health: Screening is essential for pregnant women to ensure they have enough nutrients for their health and the baby’s proper development. Deficient vitamin D levels in infants can affect their growth and cause rickets. Pregnant women are at increased risk of developing preeclampsia and giving birth preterm[6].

Don’t delay. Get screened for Vitamin D levels!

Early detection and timely intervention via screening can help safeguard against diseases and deficiencies caused due to vitamin D.
