Clinical Support for
SunVit-D3

SunVit-D3 has been tested in more than 131 subjects and the bioavailability was found to be 100% i.e. no non-responders were observed (1). The safety of daily doses ranging from 25 to 200 µg (1000-8000 IU) has also been documented (1).

What is a healthy level of Vitamin D3?

Nutritional adequacy for vitamin D is based upon the measurement of the metabolite 25-Hydroxyvitamin D. Experts agree that 25-Hydroxyvitamin D concentrations should be above 75-80 nmol/L (30-32 ng/mL) (3,12,13).

Leading experts recommend a level of 25-Hydroxyvitamin D of at least 75-80 nmol/L (3,4). This recommendation is based on a number of scientific studies:

• The absorption of calcium correlates positively with 25-Hydroxyvitamin D concentrations up to and above 80 nmol/L (14).
• The Bone Mineral Density (BMD) correlates positively with 25-hydroxyvitamin D concentrations well above 100 nmol/L (15).
• The risk of falls and fractures can be halved by increasing 25-Hydroxyvitamin D levels to above 80 to 100 nmol/L (16,17).
• The health benefits of an improved vitamin D status are well documented in the scientific literature (18).
