Supplements

Clinical significance

Vitamin D3 (Cholecalciferol) is a fat-soluble vitamin that supports calcium absorption, bone mineralization, muscle function, and immune regulation. In supplement form, it is commonly used to correct or prevent vitamin D deficiency, especially during winter, in older adults, or people with limited sun exposure.

Key Effects:

  • Supports bone health and reduces the risk of osteoporosis
  • Regulates immune function and reduces inflammation
  • May improve mood and reduce symptoms of depression
  • Supports hormonal balance and cardiovascular health

Who May Benefit (in Healsens):

  • Users with low serum 25(OH)D levels
  • Individuals with frequent infections, fatigue, or bone pain
  • During pregnancy or menopause
  • When inflammatory markers (CRP, IL-6) are elevated
  • When calcium metabolism markers (Ca, PTH) are abnormal

Recommended Use Typical dose: 1000–4000 IU/day, depending on deficiency level. Always follow guidance based on lab test results.

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 24—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.
