Supporting vitamin D production indoors with Signify VitaUp

Support natural vitamin D levels in your body

Sunlight is the main natural source of vitamin D for the human body. When exposed to UVB, the skin produces previtamin D, which begins the process of Vitamin D synthesis. As dietary sources (fortified foods and supplements) of vitamin D are limited, sunlight remains the most effective and direct method for natural synthesis.* Research shows that vitamin D plays an important role in supporting physical and emotional well-being.**

Signify VitaUp, mimics the sun’s UVB exposure, enabling indoor support for the body’s own vitamin D synthesis.

Prioritizing wellbeing

Lack of vitamin D

In general, the majority of the population has low levels of vitamin D in fall and winter. We all know how important it is to take a ‘daily dose of sunshine’. A 15-minute midday walk during spring and summer stimulates the production of vitamin D by the human body **. But it’s not summer all year round, with reduced sunshine intensity in other seasons constituting a poor source of our essential ‘sunshine vitamin’.

Daylight impact indoors

Signify VitaUp combined with Signify NatureConnect introduces a new approach to the human-centric lighting. Designed to support well-being, the NatureConnect portfolio brings positive effect of the daylight indoors by replicating a view to the sky, increasing feelings of spaciousness and elevating people’s performance.

Signify VitaUp can also be implemented independent of existing lighting solutions.

Effortless well-being

Signify VitaUp is easy to integrate into everyday spaces, making it a practical addition for those looking to support well-being effortlessly. Its familiar form factor, coupled with its low-intensity output, ensures that it is well-suited for consistent use in a variety of enclosed spaces.

Proof of concept

Signify VitaUp was tested at Sunderland Royal NHS Hospital in the UK. Results showed a significant improvement in vitamin D levels (7.13 nmol/L) compared to the control group.

The findings are published in Anticancer Research magazine.
