The peach looked beautiful. It had the feel of a peach that was ripe but not too ripe and it smelled perfect. Inside it was rotten to the core. I discovered this as I was cutting it into slices. So beautiful on the outside, so rotten on the inside. How like the United States, with […]

What is the purpose of vitamin D in the body?
Known as the “sunshine vitamin,” vitamin D is a vitamin you can get from food or supplements. Exposure to the sun also stimulates vitamin D production in the skin.
Vitamin D serves several important functions in the body. These include:
promoting calcium absorption, maintaining normal calcium and phosphate levels, promoting bone and cell growth, reducing inflammation. According to Harvard University, an estimated 1 billion people are low in vitamin D. Vitamin D deficiencies can cause short-term symptoms and long-term complications.
What are the symptoms of vitamin D deficiency?
Vitamin D deficiency doesn’t always cause symptoms. When it does, some of the symptoms may include: difficulty thinking clearly, bone pain, frequent bone fractures
muscle weakness. soft bones that may result in deformities, unexplained fatigue
Many people don’t develop symptoms until their vitamin D levels get very low or have been low for some time. This can make the condition difficult to diagnose.
Several factors have contributed to the rising incidence of vitamin D deficiency. These include: wearing sunscreen (sunscreen blocks the sun’s ability to stimulate vitamin D production), not spending enough time outside, having darkly pigmented skin, which won’t absorb the sun’s rays as well , exclusively breast-feeding babies for prolonged time periods, being obese, which typically raises your vitamin D requirements. Some people are born without the ability to process vitamin D. Other people have medical conditions that keep them from digesting vitamin D well.
How is vitamin D deficiency diagnosed?
Your doctor will start by taking your health history to determine if you’ve been experiencing symptoms that could indicate vitamin D deficiency. A doctor will likely order a blood test for the serum concentration of 25(OH)D. This is the type of vitamin D that circulates in the blood. It’s considered a good reflection of how much vitamin D you’ve absorbed from sun exposure and taken in from foods.
Levels of vitamin D are expressed in nanomoles/liter (nmol/L) or nanograms/milliliter (ng/mL). According to the Office of Dietary Supplements (ODS), the results can indicate the following: deficiency: less than 30 nmol/L (12 ng/mL)
potential deficiency: between 30 nmol/L (12 ng/mL) and 50 nmol/L (20 ng/mL)
normal levels: between 50 nmol/L (20 ng/mL) and 125 nmol/L (50 ng/mL)
high levels: higher than 125 nmol/L (50 ng/mL)
If your vitamin D levels are low and you’re having symptoms of bone pain, a doctor may recommend a special scan to check for bone density . Doctors use this painless scan to evaluate a person’s bone health.
How is vitamin D deficiency treated?
Doctors often treat vitamin D deficiencies by prescribing or recommending vitamin D supplements. The amount you should take usually depends on how low your vitamin D levels are. For example, some people may reach their vitamin D intake by taking a multivitamin. These usually have between 400 and 800 IU of vitamin D with each serving. However, people who are very deficient in vitamin D may need higher levels of supplementation — about 1,000 IU per day.
Ask your doctor how much vitamin D you need every day. The ODS recommends the following dietary allowances for eating foods that contain vitamin D as well as taking supplements: ages 0 to 12 months: 400IU, ages 1 to 70 years (including pregnancy and lactating) 600IU, ages 70 and older: 800IU
Few unfortified foods in a person’s diet are high in vitamin D. Foods that are naturally high in vitamin D include: fatty fish, such as mackerel, salmon, and tuna, beef, cheese, egg yolks, fish liver oils, mushrooms .
However, food manufacturers often add or fortify foods with vitamin D. Examples include: milk, breakfast cereals, yogurt, orange juice, margarine. Manufacturers also add vitamin D to some infant formulas to reduce the risk that infants will have low levels.
It’s also possible to increase vitamin D levels by going outside more. About 15 minutes of sun exposure (without sunscreen on) is usually enough to build up vitamin D levels. Several factors can influence the amount of sun exposure you get, including the time of year, cloud cover, and the time of day (the sun’s rays are more direct during the middle of the day). Another consideration is that ultraviolet B radiation can’t penetrate glass. This type of radiation is what stimulates vitamin D production. So even if you’re taking in sunlight through a window, you won’t get the benefit of vitamin D production.
Sunscreen is still very important to your health. If you’re going to be outside for longer than 15 minutes, you should wear sunscreen to protect against the sun’s damaging rays.
Some steps you can take to maintain healthy vitamin D levels include:
getting out in the sun without sunscreen on for 15 minutes each day
taking a multivitamin that contains vitamin D
eating foods that are high in vitamin D
purchasing and eating foods that are fortified with vitamin D, such as cereals and milk
Eating a healthy diet with fortified foods and getting some sun exposure when possible can help you keep your vitamin D at healthy levels.
