Vitamin D 14.7 ng/ml means : causes, sources, risks, treatment

In this article we discuss what a Vitamin D value of 14.7 ng/ml means, what are its causes and how to calculate your Vitamin D deficiency risk score, and how to improve your Vitamin D as well as a treatment plan and possible risks.

What does a Vitamin D level of 14.7 mean?

A vitamin d level of 14.7 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 14.7 in standard units?

In order to convert the value of Vitamin D from ng/ml into the SI Units, we must use a formula of conversion : Vitamin D in SI units (nmol/L) = Vitamin D in ng/ml*2.496¹ Based on the given formula, the value of Vitamin D in SI units for a value in ng/ml of 14.7 is 36.7 nmol/L

Is a Vitamin D value of 14.7 considered low or high?

Based on your Vitamin D value of 14.7. you are classified as having a moderate Vitamin D deficiency.

Vitamin D Levels

Category	Level (ng/mL)	Description
Severe Deficiency	< 10	Severely low vitamin D levels
Moderate Deficiency	10 - 20	Moderate Vitamin D Deficiency **You are here**
Insufficiency	20 - 30	Mild to Insufficient
Healthy	30 - 80	Normal Vitamin D Levels
Toxicity	> 80	Potentially harmful vitamin D levels

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Lamb	Lamb meat contains small amounts of Vitamin D.
Bluefin tuna	Bluefin tuna is a fatty fish that contains high levels of Vitamin D.
Herring	Herring is a fatty fish that can contribute to Vitamin D intake.
Canned salmon	Canned salmon, especially with bones, provides a convenient source of Vitamin D.
Salmon skin	Salmon skin contains some Vitamin D, but it's recommended to consume the flesh for better nutrient balance.
Canned tuna	Canned tuna, especially if it's canned with bones, can be a source of Vitamin D.
Caviar	Fish roe, or caviar, can provide small amounts of Vitamin D.
Almond milk	Some almond milk products are fortified with Vitamin D.
Fortified dairy products	Milk, yogurt, and cheese are often fortified with Vitamin D to increase intake.
Oysters	Oysters provide Vitamin D and other nutrients, though levels can vary.

What are the causes of Vitamin D deficiency?

Cause	Description
Older age	As people age, their skin becomes less efficient at converting sunlight into Vitamin D.
Multiple sclerosis	People with multiple sclerosis often have lower Vitamin D levels, although the relationship is complex.
Alcoholism	Excessive alcohol consumption can affect nutrient absorption and metabolism, including Vitamin D.
Cystic fibrosis	Individuals with cystic fibrosis are at a higher risk of Vitamin D deficiency due to malabsorption.
Liver diseases	Liver disorders can affect the conversion of Vitamin D into its active form.
Obesity	Vitamin D is stored in fat tissues, so higher body fat levels may decrease its availability.
Kidney disorders	Kidney diseases can reduce the activation of Vitamin D in the body, affecting its functions.
Living in high latitudes	At higher latitudes, the angle of sunlight is lower, leading to reduced Vitamin D synthesis in the skin.
Dark skin	Higher melanin levels in dark skin reduce the skin's ability to produce Vitamin D from sunlight.
Celiac disease	An autoimmune disorder that damages the small intestine and impairs nutrient absorption.

What symptoms will I experience with a Vitamin D of 14.7 ng/ml?

The symptoms of Vitamin D deficiency in children and adults are manifested by rickets and osteomalacia respectively. These conditions may show a variety of symptoms ranging from mild muscle pain, and bone pain to developmental abnormalities and fractures. For a Vitamin D level of 14.7 the symptoms are enlisted in the table below:

Vitamin D level 14.7 Symptoms in Children

Symptom	Description
Difficulty Breathing	In severe cases, rickets can cause deformities of the ribcage, leading to difficulty in breathing and increased susceptibility to respiratory infections.
Irritability	Children with rickets might exhibit increased irritability and discomfort due to the physical pain they experience.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.
Brittle Nails	Rickets can cause nails to become brittle and prone to breaking.
Fatigue	Chronic pain and muscle weakness can result in increased fatigue and reduced activity levels.
Vision Problems	Rickets can affect the eyes, leading to problems such as night blindness and other visual disturbances.
Weak or Soft Bones	Rickets can cause bones to become weak and soft, leading to an increased risk of fractures.
Wide Fontanelles	The soft spots on a baby's skull, known as fontanelles, might take longer to close in cases of rickets.
Bone Deformities	Rickets can lead to bone deformities, such as bowed legs or knock-knees, due to weakened bones unable to support the body's weight properly.
Delayed Walking	Some children with rickets may experience delays in achieving developmental milestones, like walking.

Vitamin D level 14.7 Symptoms in Adults

Symptom	Description
Waddling Gait	A waddling gait may develop due to weakened hip and leg muscles associated with osteomalacia.
Difficulty Standing	Weak bones and muscles can make it challenging to stand for prolonged periods.
Bone Pain	Osteomalacia often leads to bone pain, particularly in the hips, lower back, and legs.
Muscle Cramps	Deficiencies in bone mineralization and electrolytes can lead to muscle cramps and spasms.
Fatigue	Generalized fatigue and weakness are common symptoms of osteomalacia.
Delayed Healing	Fractures and injuries may take longer to heal due to impaired bone mineralization in osteomalacia.
Bone Deformities	Osteomalacia can lead to bone deformities, such as bowed legs or a curvature of the spine.
Difficulty Walking	Muscle and bone weakness can make walking and moving difficult for individuals with osteomalacia.
Short Stature	In childhood cases, untreated osteomalacia can result in short stature and growth delays.
Weight Loss	Some individuals with osteomalacia may experience weight loss due to the overall impact on health.

What additional risks do I face with a Vitamin D level of 14.7?

Level	Risk
Your value is Less Than 25	Increased risk of fallsBischoff-Ferrari
Your value is Less Than 15	Two fold higher risk of having high blood pressure as those with Vitamin D above 26Reis JP
Your value is Less Than 21	Increased risk of diabetes, hypertension, obesity and high triglyceride levelsMartins D

What is my Vitamin D deficiency score and how to calculate it?

Since your value of Vitamin D 14.7 is below the normal limit of 30, you must evaluate the following 4 factors that may be contributing to your deficiency. Based on a study done by Garg et al the following Vitamin D Insufficiency and Deficiency Score can predict and determine your causes of deficiency.

As per the study 4 major factors are invovled in Vitamin D deficiency.

Factors and Descriptions

Factor	Description
Physical Activity	Engaging in regular physical activity can contribute to improved metabolism and Vitamin D levels.
Obesity	Obesity, indicated by a body mass index (BMI) of 25 kg/m² or higher, can lead to Vitamin D deficiencies
Diet	Dietary intake of at least 100 Grams (gms) of milk/dairy products OR at least 100 gms fish or 1 egg with yolk for four or more days in the last seven days was considered Adequate
Daily Sun Exposure	Daily exposure to sunlight is important for the body's synthesis of Vitamin D. Spending at least 1.75 hours in the sun each day can help maintain Vitamin D levels, which is essential for bone health and immune function.

• Insufficiency Score for Vitamin D : 14.7

• You get less than 1.75 hours of sunlight per day
• AND
• Insufficient Dietary Intake + Obesity
• AND
• Obesity OR Insufficient Exercise
• Score : Your Vitamin D Insufficiency Score ranges between 14 - 18.

What is the treatment plan for a Vitamin D level of 14.7?

Vitamin D supplmentation is the only way to correct for deficiencies. The tables below list the dosages of Vitamin D supplements recommeded for different age groups, depending on the level of the Vitamin D. Since your value of Vitamin D is 14.7 the relevant supplement dosages are indicated below.^{Pawel Pludowski}

Recommended Daily Dosing for Vitamin D in cases where the Vitamin D Level is between 10 ng/dl and upto 30 ng/dl

A first line of treatment involves increasing the dosage to 1.5-2 x the current level of supplements if the patient is taking any supplements.

If you are not taking any supplements, the values in the table below are to be followed.

Age Group	Vitamin D Intake Per Day	Duration
Infants < 1 month	1000 IU/d	2 months
Infants 1–12 months	1000 IU/d	2 months
Children 1–11 yrs.	1429 IU/d **(Represents a value in the range of 1000 - 2000, must be adjusted as per patient.)	2 months
Children 11–18 yrs.	3347 IU/d **(Represents a value in the range of 2000 - 4000, must be adjusted as per patient.)	2 months
