What is Vitamin D?
Vitamin D3 is made by the skin when exposed to sunlight and can be found otherwise in foods and supplements. Through multiple steps, vitamin D3 is used to produce the active form in our bodies, calcitriol.
Vitamin D helps to absorb calcium to maintain bone health as well as multiple other processes in the body.
Deficiency has been associated with multiple disease processes including diabetes, heart disease, cancer and others, but the mechanism by which this occurs and causality has not been proven. Vitamin D deficiency is surprisingly common ranging from 20-40% of the population in different countries.
What does it assess?
Vitamin D levels assess the status of this essential nutrient, which is crucial for bone health, immune function, and inflammatory regulation. Adequate vitamin D supports calcium absorption, helping to maintain healthy bones and teeth, and plays a significant role in immune defence and mood regulation.
How do I optimize my Vitamin D levels?
Aim for moderate sun exposure, as sunlight is the primary natural source of vitamin D. Spending about 10-30 minutes outside, a few times per week with direct sun exposure to the skin, can help produce adequate vitamin D.
Duration may vary based on skin type, location, and time of year. Be cautious of overexposure to avoid skin damage.
Include dietary sources of vitamin D, particularly if sun exposure is limited. Fatty fish, egg yolks, fortified dairy, and plant-based milks are good options.
Calcium and magnesium are important for vitamin D utilization. Ensure sufficient intake of these minerals through diet or supplements if needed to improve vitamin D effectiveness.
What do high and low Vitamin D levels mean?
Elevated vitamin D levels, often due to excessive supplementation, can cause hypercalcemia, which may result in symptoms like nausea, weakness, and kidney issues. High levels are generally rare and preventable by using vitamin D supplements under medical supervision and avoiding excessive dosing.
Low levels can be a result of insufficient sunlight exposure, poor dietary intake, or malabsorption issues. Symptoms of deficiency include fatigue, muscle weakness, and bone pain. Long-term deficiency may contribute to osteoporosis, a weakened immune system, and increased risk of chronic conditions.
