A Comparative Dissolution and Absorption Study of an Orodispersible Powder, Chewable Tablet and Soft Gel Capsule Vitamin D3 Supplementation
- Conditions
- Vitamin D Deficiency
- Interventions
- Dietary Supplement: Orodispersible (sachet) 200000 IU vitamin D3Dietary Supplement: Soft gelatin 200000 IU vitamin D3 capsule
- Registration Number
- NCT05706259
- Lead Sponsor
- Liaquat University of Medical & Health Sciences
- Brief Summary
This is an open-labelled, randomized controlled clinical trial aimed to compare the pharmacokinetics of an orodispersible vs a soft gelatin vitamin supplementation in vitamin D deficient healthy adults.
- Detailed Description
Vitamin D is a fat-soluble vitamin used by the body for normal bone development and maintenance by increasing the absorption of calcium, magnesium, and phosphate. Vitamin D also plays a role in the nervous system, musculoskeletal system and immune system. Vitamin D deficiency has been linked with diverse health conditions including diabetes, cardiovascular diseases, breast, colorectal and prostate cancer, dementia, depression, erectile dysfunction, osteoporosis, and bone disorders. Vitamin D deficiency is a global healthcare challenge. To overcome vitamin D deficiency, a daily vitamin D supplementation of 200-1000 IU or a high dosage from 25000 to 200000 IU for 4-6 weeks, is normally recommended.
Vitamin D supplements are available over the counter in different delivery vehicles (formulations) to reach the circulatory system. In the present study the investigators aim to evaluate the pharmacokinetics of an orodispersible vitamin D supplement vs a conventional oral soft gelatin capsule, in vitamin D deficient healthy adults to assess how different vitamin D supplement formulations can efficiently overcome the vitamin D deficiency.
