NOW® Vitamin D-3 soft gels supply this key vitamin in a highly-absorbable liquid soft gel form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However‚ it is not abundant in food. As more people avoid sun exposure‚ Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply.


What is vitamin D? What effect does it have?
Vitamin D is a nutrient in certain foods that is necessary for health and to keep bones strong. It does this by helping the body absorb calcium (one of the building blocks of bones) from food and supplements. People who consume too little vitamin D may have weak, thin, and brittle bones, a condition called rickets in children and osteomalacia in adults.

Also, vitamin D is very important to the body in many other ways. Muscles require this vitamin for movement. For example, nerves need it to transmit messages between the brain and every part of the body, and the immune system uses vitamin D to fight viruses and bacteria that invade it. Along with calcium, vitamin D helps protect older adults against osteoporosis. Vitamin D is found in cells throughout the body.

How much vitamin D do I need?
The amount of vitamin D you need per day depends on your age. The average daily amounts of vitamin D are listed below in micrograms (mcg) and in international units (IU):

Life Stage Recommended Amount
Babies up to 12 months of age 10 mcg (400 IU)
Children 1-13 years old 15 mcg (600 IU)
Teens 14-18 years old 15 mcg (600 IU)
Adults 19-70 years old 15 mcg (600 IU)
Adults over 71 years of age 20 mcg (800 IU)
Pregnant and lactating women 15 mcg (600 IU)

What foods are a source of vitamin D?
Very few foods contain this vitamin naturally. Foods fortified with added vitamin D provide most of this vitamin in the diets of people in the United States.

Fatty fish, such as salmon, tuna, and mackerel are among the best sources of vitamin D.
Beef liver, cheese, and egg yolk contain smaller amounts.
Mushrooms provide a certain amount of vitamin D. In certain types of mushrooms now on sale, the vitamin D content is increased by exposing them to ultraviolet light.
Almost the entire milk supply in the United States is fortified with 400 IU of vitamin D per liter, as well as many plant-based alternatives, such as soy milk, almond milk, and oat milk. However, foods made with milk, such as cheese and ice cream, are generally not fortified.
Also, certain breakfast cereals and some brands of orange juices, yogurts, margarine, and soy-based beverages contain added vitamin D. Always check labels.

Does vitamin D provide sunlight?
The skin produces vitamin D when exposed to direct sunlight. Most people meet at least part of their vitamin D requirement in this way. Skin exposed to sunlight indoors, through a window, does not produce vitamin D. On cloudy days, shade and dark-colored skin also reduce the amount of vitamin D the skin produces.

However, despite the importance of the sun for the synthesis of vitamin D, it is prudent to limit skin exposure to sunlight to reduce the risk of skin cancer. If you are exposed to the sun for only a few minutes, wear protective clothing and a sunscreen with a sun protection factor (SPF) of at least 8. Sunbeds also allow the skin to produce vitamin D, although they present similar risks of skin cancer.

Those who avoid the sun or cover their bodies with sunscreen or clothing should include rich sources of vitamin D in their diet or take a supplement. Recommended vitamin D intakes are determined on the assumption of poor sun exposure.

What types of vitamin D dietary supplements are there?
Vitamin D is found in supplements (and fortified foods) in two different forms: D2 (ergocalciferol) and D3 (cholecalciferol). Both increase the concentration of vitamin D in the blood.
