Vitamin D 9.4 ng/ml means : causes, sources, risks, treatment

In this article we discuss what a Vitamin D value of 9.4 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 9.4 mean?

A vitamin d level of 9.4 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 9.4 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 9.4 is 23.5 nmol/L

Is a Vitamin D value of 9.4 considered low or high?

Based on your Vitamin D value of 9.4. you are classified as having a severe Vitamin D deficiency.

Vitamin D Levels

Severe Deficiency	< 10	Severely low vitamin D levels **You are here**
Moderate Deficiency	10 - 20	Moderate Vitamin D Deficiency
Insufficiency	20 - 30	Mild to Insufficient

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Beef liver	Organ meats like beef liver contain Vitamin D, though levels can vary.
Caviar	Fish roe, or caviar, can provide small amounts of Vitamin D.
Tofu	Some tofu products are fortified with Vitamin D, especially those made from soy milk.
Trout	Trout can provide Vitamin D, particularly when caught in the wild.
Salmon skin	Salmon skin contains some Vitamin D, but it's recommended to consume the flesh for better nutrient balance.
Fortified orange juice	Certain brands of orange juice are fortified with Vitamin D to increase its nutritional value.
Mushrooms	Some mushrooms exposed to UV light can produce Vitamin D2.
Egg yolks	Egg yolks contain small amounts of Vitamin D, especially if the hens are raised on Vitamin D-enriched feed.
Sunlight exposure	The skin produces Vitamin D when exposed to sunlight, specifically UVB rays.
Fortified cereals	Many cereals are enriched with Vitamin D to improve nutritional content.

What are the causes of Vitamin D deficiency?

Cause	Description
Lack of fortified foods	A diet lacking in fortified dairy products or cereals may lead to lower Vitamin D intake.
Certain hormonal disorders	Hormonal imbalances can influence Vitamin D metabolism and its effects on the body.
Alcoholism	Excessive alcohol consumption can affect nutrient absorption and metabolism, including Vitamin D.
Kidney disorders	Kidney diseases can reduce the activation of Vitamin D in the body, affecting its functions.
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.
Older age	As people age, their skin becomes less efficient at converting sunlight into Vitamin D.
Chronic kidney disease	Kidney dysfunction can disrupt the activation of Vitamin D, leading to deficiency.
Multiple sclerosis	People with multiple sclerosis often have lower Vitamin D levels, although the relationship is complex.
Crohn's disease	An inflammatory bowel disease that can lead to malabsorption and nutrient deficiencies.

What symptoms will I experience with a Vitamin D of 9.4 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 9.4 the symptoms are enlisted in the table below:

Vitamin D level 9.4 Symptoms in Children

Symptom	Description
Vision Problems	Rickets can affect the eyes, leading to problems such as night blindness and other visual disturbances.
Brittle Nails	Rickets can cause nails to become brittle and prone to breaking.
Enlarged Joints	Swelling and tenderness in the joints can occur as a result of rickets.
Delayed Growth	Children with rickets may experience slowed growth and development compared to their peers.
Delayed Puberty	In severe cases, rickets can delay the onset of puberty due to its impact on bone and overall development.
Bone Pain	Children with rickets often complain of bone pain, which can be especially pronounced in the legs, pelvis, and spine.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.
Muscle Weakness	Muscle weakness can result from compromised bone health and nutritional deficiencies associated with 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.
Irritability	Children with rickets might exhibit increased irritability and discomfort due to the physical pain they experience.

Vitamin D level 9.4 Symptoms in Adults

Symptom	Description
Bone Pain	Osteomalacia often leads to bone pain, particularly in the hips, lower back, and legs.
Bone Deformities	Osteomalacia can lead to bone deformities, such as bowed legs or a curvature of the spine.
Easy Bruising	Weakened bones and blood vessels can lead to easy bruising in individuals with osteomalacia.
Chest Deformities	In severe cases, osteomalacia can lead to deformities in the ribs and chest.
Weight Loss	Some individuals with osteomalacia may experience weight loss due to the overall impact on health.
Muscle Cramps	Deficiencies in bone mineralization and electrolytes can lead to muscle cramps and spasms.
Difficulty Standing	Weak bones and muscles can make it challenging to stand for prolonged periods.
Fatigue	Generalized fatigue and weakness are common symptoms of osteomalacia.
Frequent Infections	Impaired bone health can weaken the immune system, leading to an increased susceptibility to infections.
Difficulty Walking	Muscle and bone weakness can make walking and moving difficult for individuals with osteomalacia.

What additional risks do I face with a Vitamin D level of 9.4?

Your value is Less Than 10	40% more risk of mortality compared to those with vitamin d above 40Ginde AA
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 9.4 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 : 9.4

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

What is the treatment plan for a Vitamin D level of 9.4?

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 9.4 the relevant supplement dosages are indicated below.^{Pawel Pludowski}
