Tips for Increasing Your Vitamin D Intake
- Eat fish, especially fatty fish such as salmon and mackerel, 2 times per week.
- Drink vitamin D-fortified milk.
- Get sun exposure, but be careful to watch for sunburn. Sunlight is a major cause of skin cancer. Fifteen summer minutes of sun exposure to face and arms will allow most persons to synthesize adequate vitamin D and minimize the risk of skin damage. If you will be out in the sun for more than a few minutes, it is important to protect against skin cancer by wearing protective clothing or putting on sunscreen with an SPF (sun protection factor) of 30 or more. In most northern climates, winter sun is too obstructed and low in the sky to allow vitamin D synthesis in the skin. In the winter, vitamin D supplements or multiple servings of milk and fatty fish may be necessary for good health.
