These wavelengths are available when the UV index is more prominent. The angle of the Sun over the horizon likewise influences the synthesis of vitamin D because the atmosphere is thicker at lower points and absorbs more UV.

At angles more than 45 degrees above the horizon, vitamin D synthesis will occur, although some recent studies recommend that vitamin D synthesis may happen at angles as low as 30 degrees.

At higher altitudes, there are fewer atmospheres to absorb UV from the Sun.

 

UV Lamps for supplementing Vitamin D

During the winter, the amount of UV-B is less. UVB is the band of UV light that is in charge of synthesis of Vitamin D.
