• To naturally produce vitamin D your skin needs to be exposed to the UVB radiation.
• Unless the sun is at an elevation higher than 45° the UVB is filtered out by the atmosphere.
• At this time of the year the sun never reaches over 45° where you are. Next time it does that will be on 4 Sept 2025.
