Vitamin D, 25-OH Vitamin D, 25(OH)D Blood Test

What it measures

Vitamins

Clinical significance

Your body converts vitamin D into a form called 25-hydroxyvitamin D (25(OH)D), also known as calcidiol. The 25(OH)D blood test is considered the most reliable way to assess vitamin D status. The level of 25-hydroxyvitamin D in the blood reflects the total amount of vitamin D obtained from sunlight, food, and supplements.

πŸ” What levels are considered optimal?

  • Levels between 30 and 50 ng/mL are generally considered sufficient for overall health.
  • Levels below 12 ng/mL indicate vitamin D deficiency.

πŸ”· Vitamin D and overall health:

Vitamin D plays an important role in bone metabolism, immune function, and muscle health. Low levels may affect multiple systems in the body.

Common signs associated with low vitamin D levels may include:

  • Fatigue
  • Bone discomfort
  • Joint and muscle pain
  • Low energy levels
  • Increased susceptibility to infections
  • Changes in mood

Vitamin D deficiency may result from limited sun exposure, reduced synthesis in the skin, insufficient dietary intake, or underlying health conditions. These may include gastrointestinal disorders affecting absorption, as well as liver and kidney diseases involved in vitamin D metabolism.

My journey back to health with Healsens. Thank you!!

That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24β€”nearly a decade younger than my real age.

Useful app to track analytics and 2nd opinion

It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!

Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.

A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
