NOW® Vitamin D-3 softgels supply this key vitamin in a highly-absorbable liquid softgel 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 Vitamin D does: Promotes bone growth, cell growth, neuromuscular and immune function. It also helps reduce inflammation.

Why you need Vitamin D: Without sufficient vitamin D, bones can become thin, brittle, or misshapen, leading to osteomalacia, or a softening of the bones, which can weaken muscles, too. 

Vitamin D deficiency has also been shown to play a role in the development of type 1 and type 2 diabetes.

The good news: Evidence suggests that vitamin D may provide some protection against colorectal and possibly other cancers, according to Glassman.

What is Vitamin D?

Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy.

A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults

Vitamin D is known as a fat-soluble vitamin but is actually a group of fat-soluble secosteroids of which two, ergocalciferol and cholecalciferol, are important for humans.

In the human body cholecalciferol can be synthesized from cholesterol in sun-exposed skin, hence its nickname the “Sunshine Vitamin.”

Ergocalciferol can only be synthesized from plant sterols (phytosterols), but is beneficial for humans in dietary and supplemental form, as is cholecalciferol.

Cholecalciferol and Ergocalciferol are both converted in the liver to the vitamin D metabolites that are measured in serum to determine a person’s vitamin D status, 25 hydroxycholecalciferol and 25-hydroxyergocalciferol respectively which in turn are precursors of the active forms of vitamin D.

What has it done for you lately?

Vitamin D enhances the intestinal absorption of the dietary minerals calcium, magnesium, phosphate, and zinc and therefore plays an important role in skeletal health.*

Low levels of vitamin D have been associated with low bone mineral density.*

Vitamin D also supports healthy immune system function, and recent research has shown that vitamin D may play a role in normal cardiovascular function as well.*

Vitamin D is referred to as a fat-soluble vitamin, but this nutrient is actually a group of fat-soluble secosteroids, which are natural substances similar to steroids but with a particular structural difference.

Two of these secosteroids, cholecalciferol (vitamin D-3) and ergocalciferol (vitamin D-2), are important for our health.

There aren’t a lot of foods high in vitamin D. Our primary source of natural vitamin D, cholecalciferol, is actually synthesized by our bodies from cholesterol in sun-exposed skin, earning it the nickname

“The Sunshine Vitamin”. Some dietary sources of vitamin D-3 are fatty fish and egg yolks. 

The other relevant form of vitamin D, ergocalciferol, is found primarily in fungus, lichen and a few plants such as alfalfa. Both forms are beneficial for human health.

What is vitamin D deficiency?

Vitamin D deficiency means that you do not have enough vitamin D in your body. Vitamin D is unique because your skin actually produces it by using sunlight.

Fair-skinned individuals and those who are younger convert sunshine into vitamin D far better than those who are darker-skinned and over age 50.

What are the health effects of vitamin D deficiency?

Getting enough vitamin D may also play a role in helping to keep you healthy by protecting against the following conditions and possibly helping to treat them.

These conditions can include:

Vitamin D—nicknamed the “sunshine vitamin” due to its ability to be absorbed by the body through sunlight—is a major player in keeping the human body healthy.

Its main job, according to the National Institutes of Health’s Office of Dietary Supplements, is to promote calcium absorption, making it necessary for bone growth and bone remodeling (when mature bone tissue is removed and new bone tissue is formed).

Because of that, a lack of vitamin D can lead to thin, brittle, or misshapen bones. But vitamin D offers a range of other benefits too, ranging from positives for both physical and mental health.

Here are nine vitamin D benefits you need to know about—including ways to get more of the vitamin in your daily diet.

Calcium and Vitamin D


Calcium and vitamin D are essential to building strong, dense bones when you’re young and to keeping them strong and healthy as you age.

Cheese, milk, fish, almonds, and other bone-healthy foodsA calcium-rich diet (including dairy, nuts, leafy greens and fish) helps to build and protect your bones.

What is Calcium and What Does it Do?

Calcium is a mineral that is necessary for life. About 99% of the calcium in our bodies is in our bones and teeth.

Every day, we lose calcium through our skin, nails, hair, sweat, urine, and feces. Our bodies cannot produce its own calcium. That’s why it’s important to get enough calcium from the food we eat. When we don’t get the calcium our body needs, it is taken from our bones. This is fine once in a while, but if it happens too often, bones get weak and easier to break.
