What does a Vitamin D level of 14.3 mean?

A vitamin d level of 14.3 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 14.3 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 14.3 is 35.7 nmol/L

Is a Vitamin D value of 14.3 considered low or high?

Based on your Vitamin D value of 14.3. you are classified as having a moderate Vitamin D deficiency.

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Salmon skin	Salmon skin contains some Vitamin D, but it's recommended to consume the flesh for better nutrient balance.
Mushrooms	Some mushrooms exposed to UV light can produce Vitamin D2.
Fatty fish (salmon, mackerel, tuna)	Fatty fish are excellent sources of Vitamin D, particularly wild-caught species.
Canned mackerel	Canned mackerel, like fresh mackerel, is a good source of Vitamin D.
Fortified orange juice	Certain brands of orange juice are fortified with Vitamin D to increase its nutritional value.
Canned tuna	Canned tuna, especially if it's canned with bones, can be a source of Vitamin D.

Fortified cereals	Many cereals are enriched with Vitamin D to improve nutritional content.

What are the causes of Vitamin D deficiency?

Cause	Description
Being homebound or institutionalized	Limited exposure to sunlight due to confinement indoors can lead to deficiency.
Osteoporosis	Vitamin D is essential for bone health, and deficiency can contribute to conditions like osteoporosis.
Gastric bypass surgery	Surgical procedures that alter the digestive system can limit the absorption of nutrients, including Vitamin D.
Limited sunlight exposure	Insufficient exposure to sunlight, which is necessary for the skin to produce Vitamin D.
Malabsorption disorders	Conditions like celiac disease can affect the body's ability to absorb Vitamin D from the digestive tract.
Certain genetic factors	Certain genetic variations can impact how the body processes and uses Vitamin D.
Crohn's disease	An inflammatory bowel disease that can lead to malabsorption and nutrient deficiencies.
Alcoholism	Excessive alcohol consumption can affect nutrient absorption and metabolism, including Vitamin D.
Premature birth	Premature infants may have underdeveloped systems for producing and utilizing Vitamin D.
Certain medications (e.g., anticonvulsants)	Some medications interfere with Vitamin D metabolism and absorption.

What symptoms will I experience with a Vitamin D of 14.3 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 14.3 the symptoms are enlisted in the table below:

Vitamin D level 14.3 Symptoms in Children

Symptom	Description
Delayed Growth	Children with rickets may experience slowed growth and development compared to their peers.
Enlarged Joints	Swelling and tenderness in the joints can occur as a result 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.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.
Delayed Puberty	In severe cases, rickets can delay the onset of puberty due to its impact on bone and overall development.
Delayed Walking	Some children with rickets may experience delays in achieving developmental milestones, like walking.
Dental Problems	Rickets can affect the development of teeth, leading to dental issues such as delayed eruption and enamel defects.
Delayed Healing	Fractures and other injuries may take longer to heal in children with rickets.
Delayed Teething	Children with rickets might experience delays in the eruption of their teeth.
Brittle Nails	Rickets can cause nails to become brittle and prone to breaking.

Vitamin D level 14.3 Symptoms in Adults

Symptom	Description
Bone Tenderness	Bones affected by osteomalacia can become tender to the touch.
Depression	Chronic pain and physical limitations in osteomalacia can contribute to feelings of depression.
Joint Pain	Osteomalacia-related muscle and bone weakness can result in joint pain and discomfort.
Bone Pain	Osteomalacia often leads to bone pain, particularly in the hips, lower back, and legs.
Muscle Weakness	Muscle weakness can result from the lack of proper mineralization in the bones caused by osteomalacia.
Short Stature	In childhood cases, untreated osteomalacia can result in short stature and growth delays.
Frequent Infections	Impaired bone health can weaken the immune system, leading to an increased susceptibility to infections.
Chest Deformities	In severe cases, osteomalacia can lead to deformities in the ribs and chest.
Delayed Healing	Fractures and injuries may take longer to heal due to impaired bone mineralization in osteomalacia.
Muscle Cramps	Deficiencies in bone mineralization and electrolytes can lead to muscle cramps and spasms.

What additional risks do I face with a Vitamin D level of 14.3?

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 14.3 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 : 14.3

• 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 14.3?

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 14.3 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.
