Vitamin D is known as the ‘sunshine vitamin’ because your body NEEDS sunlight to make it. When UVB rays from the sun hit your skin, your cells convert cholesterol into vitamin D.

Vitamin D deficiency is a huge problem, and many people have low levels without even knowing it. Here’s a non-exhaustive list of things your body uses vitamin D for...


Calcium absorption
Bone health
Immune function
Muscle strength
Weight management

Sunshine is the most efficient way to support vitamin D levels, but not if you’re wearing sunscreen! Sunscreen blocks UVB rays and vitamin D production.

The good news is that you don’t need long periods of sun exposure to make enough vitamin D. One study in the UK found that 13 minutes of midday sun exposure 3 days per week was enough to maintain healthy vitamin D levels. A study in Norway found that 30 minutes of midday sun was equivalent to consuming 10,000 - 20,000 IU of vitamin D.

You don’t want to risk getting a sunburn, but your vitamin D levels could benefit from brief periods of direct sunlight before applying the sunscreen.

And remember - you can always get your vitamin D levels checked with a simple blood test! Just call my clinic for more info.
