Nutrigenomics Vitamin D Requirement

Based on your genetics, your genetic predisposition for Vitamin D Requirement is


What does this mean?

Likely to have no increased risk of vitamin D deficiency Your genotypes indicate that you are likely to have typical serum level of vitamin D and no increased risk for vitamin D deficiency. Hence, maintain and monitor your vitamin D intake. The recommended vitamin D intake is 15 mcg/day for adults aged 19-65 years old and 20 mcg/day for elderly. The upper tolerable intake for adults is 100 mcg/day (RNI for Malaysia).

How Is Your Genetic Risk Calculated?

This result is based on the SNPs(single nucleotide polymorphism)that are associated with Vitamin D Requirement.

What is Vitamin D Requirement?

Vitamin D is the sunshine vitamin. The human body can synthesise sufficient vitamin D when the skin is exposed to adequate amounts of sunlight. The dietary sources of vitamin D include food and dietary supplements. Vitamin D plays an essential role in the regulation of metabolism, calcium, and phosphorus absorption of bone health. Vitamin D adequacy is best determined by measurement of the 25-hydroxyvitamin D concentration (25(OH)D levels) in the blood.

Do you have vitamin D deficiency?
