National Center for Biotechnology InformationU. Photosynthesis of vitamin D3 in the skin depends upon season and latitude, time of day, and on the amount pigment photosythesis games thickness of the skin.

decreases dramatically, which may inhibit vitamin D synthesis in humans. Therefore, a larger dose . conversion of the cutaneous vitamin D precursor, 7-dehy-.
