“The reduced exposure to sunlight
and lower vitamin D levels of many women over 50
can reduce the absorption of calcium for bone strength”.1
Definition
What is vitamin D?
Depending on the Source (DotS) the definition of vitamin D may vary. The (United States) Office of Dietary Supplements’ (ODS) definition is:
“Vitamin D is a nutrient you need for good health. It helps your body absorb calcium, one of the main building blocks for strong bones. Together with calcium, vitamin D helps protect you from developing osteoporosis, a disease that thins and weakens the bones and makes them more likely to break. Your body needs vitamin D for other functions too. Your muscles need it to move, and your nerves need it to carry messages between your brain and your body. Your immune system needs vitamin D to fight off invading bacteria and viruses”.2
Role
What is the role of Vitamin D?
In Vitamin D: The Importance of Vitamin D according to the (Australian) Jean Hailes for Women’s Health (JH):
- Bone development and strength
- Cell growth
- Maintaining a healthy immune system
- Hormone function
- Nervous system regulation
Apart from its important role in maintaining bone health, vitamin D may also have an important role in other diseases such as diabetes, cancer and infection. These are currently areas of intense research”.3
Sources of Vitamin D
What are sources of vitamin D?
In Vitamin D: What Foods Provide Vitamin D? the ODS explain:
- Almost all of the U.S. milk supply is fortified with about 3 mcg (120 IU) vitamin D per cup. Many plant-based alternatives such as soy milk, almond milk, and oat milk are similarly fortified. But foods made from milk, like cheese and ice cream, are usually not fortified
- Vitamin D is added to many breakfast cereals and to some brands of orange juice, yogurt, margarine, and other food products
- Fatty fish (like trout, salmon, tuna, and mackerel) and fish liver oils are among the best natural sources of vitamin D
- Beef liver, egg yolks, and cheese have small amounts of vitamin D
- Mushrooms provide a little vitamin D. Some mushrooms have been exposed to ultraviolet light to increase their vitamin D content”.4
Daily
How much vitamin D should women over 50, aim for daily?
DoY (Depending on You) and DotS this may vary. It can therefore be in your best interest to choose to check what’s-what for you.
Sun
What is the association between the sun and vitamin D?
The ODS explain:

Ultraviolet radiation from sunshine can cause skin cancer, so it’s important to limit how much time you spend in the sun. Although sunscreen limits vitamin D production, health experts recommend using sunscreen with a sun protection factor (SPF) of 15 or more when you’re out in the sun for more than a few minutes”.5
Calcium
What is the association between calcium and vitamin D?
On page one in Calcium and Calcium Supplements: Achieving the Right Balance – Calcium and Diet the (United States) Mayo Clinic elaborate on:
“To absorb calcium, your body also needs vitamin D. A few foods naturally contain small amounts of vitamin D, such as canned salmon with bones and egg yolks. You can also get vitamin D from fortified foods and sun exposure”.6
Bone Strength
What is the association between bone strength and vitamin D?
In Calcium: Recommended Daily Calcium Intake – Women: 50+ the JH explain:
- “The reduced exposure to sunlight and lower vitamin D levels of many women over 50 can reduce the absorption of calcium for bone strength”.7
Level
How may I find out my level of vitamin D?
In Vitamin D: What You Need To Know the JH note:
- “See your doctor to have a blood test to determine your level of vitamin D”.8
Health Care Provider
What if I think I need to take a vitamin D supplement?
If you think you need to take a vitamin D supplement, it may be in your best interest to choose to talk to your health care provider about this.
In Vitamin D: What You Need To Know the JH also explain:
- “Your treating doctor can recommend whether you need to take a vitamin D supplement”.9
