Vitamin D 8.3 ng/ml means : causes, sources, risks, treatment

In this article we discuss what a Vitamin D value of 8.3 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 8.3 mean?

A vitamin d level of 8.3 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 8.3 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 8.3 is 20.7 nmol/L

Is a Vitamin D value of 8.3 considered low or high?

Based on your Vitamin D value of 8.3. you are classified as having a severe Vitamin D deficiency.

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Canned tuna	Canned tuna, especially if it's canned with bones, can be a source of Vitamin D.
Lamb	Lamb meat contains small amounts of Vitamin D.
Trout	Trout can provide Vitamin D, particularly when caught in the wild.

Canned mackerel	Canned mackerel, like fresh mackerel, is a good source of Vitamin D.
Halibut	Halibut is a fish that contains moderate levels 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
Obesity	Vitamin D is stored in fat tissues, so higher body fat levels may decrease its availability.
Chronic kidney disease	Kidney dysfunction can disrupt the activation of Vitamin D, leading to deficiency.
Limited outdoor activities	A sedentary lifestyle with minimal outdoor time can result in reduced sunlight exposure.
Older age	As people age, their skin becomes less efficient at converting sunlight into Vitamin D.
Gastric bypass surgery	Surgical procedures that alter the digestive system can limit the absorption of nutrients, including Vitamin D.
Certain autoimmune diseases	Autoimmune disorders may interfere with Vitamin D metabolism and utilization.
Osteoporosis	Vitamin D is essential for bone health, and deficiency can contribute to conditions like osteoporosis.
Certain genetic factors	Certain genetic variations can impact how the body processes and uses Vitamin D.
Certain types of cancer	Some cancers and their treatments can impact Vitamin D levels and metabolism.
Certain hormonal disorders	Hormonal imbalances can influence Vitamin D metabolism and its effects on the body.

What symptoms will I experience with a Vitamin D of 8.3 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 8.3 the symptoms are enlisted in the table below:

Vitamin D level 8.3 Symptoms in Children

Symptom	Description
Delayed Healing	Fractures and other injuries may take longer to heal in children with rickets.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.
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 Teething	Children with rickets might experience delays in the eruption of their teeth.
Delayed Walking	Some children with rickets may experience delays in achieving developmental milestones, like walking.
Fatigue	Chronic pain and muscle weakness can result in increased fatigue and reduced activity levels.
Delayed Puberty	In severe cases, rickets can delay the onset of puberty due to its impact on bone and overall development.
Dental Problems	Rickets can affect the development of teeth, leading to dental issues such as delayed eruption and enamel defects.
Delayed Growth	Children with rickets may experience slowed growth and development compared to their peers.
Curvature of the Spine	Rickets can contribute to spinal deformities, such as scoliosis or kyphosis (excessive forward curvature of the upper spine).

Vitamin D level 8.3 Symptoms in Adults

Symptom	Description
Short Stature	In childhood cases, untreated osteomalacia can result in short stature and growth delays.
Easy Bruising	Weakened bones and blood vessels can lead to easy bruising in individuals with osteomalacia.
Muscle Weakness	Muscle weakness can result from the lack of proper mineralization in the bones caused by osteomalacia.
Chest Deformities	In severe cases, osteomalacia can lead to deformities in the ribs and chest.
Difficulty Walking	Muscle and bone weakness can make walking and moving difficult for individuals with osteomalacia.
Tingling or Numbness	Nerve-related symptoms such as tingling or numbness can occur as a result of osteomalacia.
Delayed Healing	Fractures and injuries may take longer to heal due to impaired bone mineralization in osteomalacia.
Difficulty Climbing Stairs	Muscle weakness and bone pain can make climbing stairs difficult for those with osteomalacia.
Bone Pain	Osteomalacia often leads to bone pain, particularly in the hips, lower back, and legs.
Bone Tenderness	Bones affected by osteomalacia can become tender to the touch.

What additional risks do I face with a Vitamin D level of 8.3?

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 8.3 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 : 8.3

• 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 8.3?

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