How do you get 100% vitamin D?

Reaching 100% vitamin D requires a multi-pronged approach, combining the natural boost of sunlight with dietary sources and, potentially, supplementation. Here’s a breakdown of the key methods:

1. Bask in the Sunshine

Our bodies naturally synthesize vitamin D when exposed to UVB rays from the sun. Ideally, aim for 15–20 minutes of midday sun exposure, without sunscreen, on bare skin (like arms, legs, or back) most days of the week. However, factors like season, location, and skin tone can affect synthesis. Consult your doctor to determine the optimal sun exposure for your situation.

2. Eat Vitamin D-Rich Foods

While sunlight reigns supreme, incorporating vitamin D-rich foods into your diet can give your levels a welcome boost. Fatty fish like salmon, tuna, sardines, and mackerel are excellent sources. Smaller fish like anchovies and herring also pack a punch. Other dietary options include egg yolks, beef liver, and fortified foods like milk, yogurt, and cereals. Remember, consistency is key, so strive to include these foods regularly in your meals.

3. Consider Supplementation

If sun exposure and dietary intake fall short, vitamin D supplements can be a useful tool. Consulting your doctor is crucial to determine the appropriate dosage and form (D2 or D3) for your individual needs. Start with the recommended dose and monitor your levels through blood tests to ensure optimal levels without the risk of overdosing.


Reaching and maintaining 100% vitamin D requires a personalized approach. While striving for this ideal, don’t neglect the benefits of incorporating the above methods into your lifestyle. Regular sun exposure (with awareness), a balanced diet with vitamin D-rich foods, and potentially supplementation, can work together to ensure your body has the vitamin D it needs for optimal health and well-being.
