It is estimated that over 40% of our population has low vitamin d levels. Unfortunately, as we age, our ability to convert dietary vitamin d into its active form diminishes, as does our ability to synthesize vitamin d from sunshine, reducing our body’s vitamin d levels further.
Therefore, people 50 years old and above are at an increased risk of developing vitamin d deficiency. A simple blood test can determine your vitamin d level (a result of 20 ng/ml to 50ng/ml is considered adequate for healthy people) and can help you select the right supplement dosage along with a discussion with your doctor.
