What is Vitamin D?
A fat-soluble vitamin with important functions in our body. For example, Vitamin D helps calcium absorption.Vitamin D is made in the skin under the influence of sunlight, but this production decreases with increasing age. Interestingly, older Chinese Malaysian men with high physical activity level and a lower BMI have been found to have higher serum Vitamin D level.
Vitamin D is available in 2 forms: Vitamin D2 and Vitamin D3. There is no difference between D2 & D3 for raising the blood levels of Vitamin D in our body. BUT, research shows that Vitamin D3 is more efficacious in increasing our Vitamin D level.
•79% of Malaysian aged 13 yrs are deficient in Vitamin D3, with Malay ladies at higher risk.
•49% of Malaysian post-menopausal women are deficient in Vitamin D3.
Research shows inadequate Vitamin D has been linked with:
👉 Increased risk of fractures in older adults
👉 Age-related high blood pressure
👉 Age-related macular (eye) degeneration
👉 Twice the risk of having heart attack
👉 Poor diabetes control
👉 Cognitive decline
According to the Malaysia Recommended Nutrient Intake, one should have at least 15μg (600IU) Vitamin D daily. The best way to know if you are getting enough is to do a blood test.
As Vitamin D is available from your diet and direct sunlight, how do you know if you need supplementation?
▶ If the blood test shows that you are Vitamin D deficient.
▶ If you aren't able to be outdoors between 11am and 3pm.
▶ If you regularly have digestive issues that may affect effective Vitamin D absorption from your diet.
