At what time of the day is vitamin D more available in the sun?

Vitamin D production in the skin occurs when it is exposed to ultraviolet B (UVB) radiation from the sun. The production of vitamin D is influenced by various factors, including the time of day, season, latitude, altitude, cloud cover, and skin pigmentation.

Generally, the best time to get vitamin D from the sun is when the sun is at its highest point in the sky, which is typically between 10 a.m. and 3 p.m. During this time, the sun’s rays are at a more direct angle, providing more UVB radiation to your skin, which is essential for vitamin D synthesis.

It’s important to note that exposure to the sun should be balanced to minimize the risk of sunburn and skin damage. It’s recommended to spend a brief amount of time in the sun, gradually increasing the duration to allow your skin to produce vitamin D without harming your skin. Additionally, factors like your geographic location, skin type, and sunscreen use can affect the amount of vitamin D your body produces from sun exposure. If you have concerns about vitamin D levels, consider consulting a healthcare professional.
