While direct sunlight is the best source of vitamin D, new research shows that it takes 48 hours from the time of the sun exposure on the skin for the vitamin D to reach the blood. In the interim, this oil-soluble vitamin can be washed away with soap, oils, or body lotions that prevent its absorption. Once you’ve had moderate sun exposure refrain from washing your sun-exposed skin with soap–simply wash with water and reserve soap for the armpit and groin areas only. If you slather on sunscreens, you’ll also limit your vitamin D intake. Now, I’m not suggesting that everyone becomes a sun worshipper–moderation is key.
Also, if the sun exposure you’re getting is through your home, office, or car windows, you could be getting UV-A rays that actually deplete vitamin D.
You can also obtain some vitamin D from fish, fish oil, sweet potatoes, sunflower seeds, mushrooms, and many types of sprouts, but the amounts are minimal and sunlight is still the best option. When supplementing always choose the natural form of vitamin D–vitamin D3. Dosages vary depending on the person, usually starting at 1000 IU/day. Some health experts report the reversal of skin and mood disorders on higher doses.
Because vitamin D production is dependent on having adequate cholesterol in your body, you may especially need to supplement with vitamin D if you’re taking statin drugs to lower cholesterol levels. Consult with a natural health or medical practitioner to determine if vitamin D supplementation is right for you.
