Vitamin D 29.0 ng/ml means : causes, sources, risks, treatment

In this article we discuss what a Vitamin D value of 29.0 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 29.0 mean?

A vitamin d level of 29.0 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 29.0 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 29.0 is 72.4 nmol/L

Is a Vitamin D value of 29.0 considered low or high?

Based on your Vitamin D value of 29.0. you are classified as having a mild or insufficient Vitamin D deficiency

Vitamin D Levels

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Shrimp	Shrimp contain some Vitamin D, especially when consumed in larger quantities.
Fortified orange juice	Certain brands of orange juice are fortified with Vitamin D to increase its nutritional value.
Trout	Trout can provide Vitamin D, particularly when caught in the wild.
Fortified cereals	Many cereals are enriched with Vitamin D to improve nutritional content.
Sunlight exposure	The skin produces Vitamin D when exposed to sunlight, specifically UVB rays.
Caviar	Fish roe, or caviar, can provide small amounts of Vitamin D.
Beef liver	Organ meats like beef liver contain Vitamin D, though levels can vary.
Salmon skin	Salmon skin contains some Vitamin D, but it's recommended to consume the flesh for better nutrient balance.
Mackerel	Mackerel is a fatty fish with high Vitamin D content.
Canned tuna	Canned tuna, especially if it's canned with bones, can be a source of Vitamin D.

What are the causes of Vitamin D deficiency?

Cause	Description
Multiple sclerosis	People with multiple sclerosis often have lower Vitamin D levels, although the relationship is complex.
HIV/AIDS	The virus and certain treatments can affect nutrient absorption and utilization, 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.
Crohn's disease	An inflammatory bowel disease that can lead to malabsorption and nutrient deficiencies.
Certain medications (e.g., anticonvulsants)	Some medications interfere with Vitamin D metabolism and absorption.
Certain autoimmune diseases	Autoimmune disorders may interfere with Vitamin D metabolism and utilization.
Cystic fibrosis	Individuals with cystic fibrosis are at a higher risk of Vitamin D deficiency due to malabsorption.
Certain hormonal disorders	Hormonal imbalances can influence Vitamin D metabolism and its effects on the body.
Being homebound or institutionalized	Limited exposure to sunlight due to confinement indoors can lead to deficiency.

What symptoms will I experience with a Vitamin D of 29.0 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 29.0 the symptoms are enlisted in the table below:

Vitamin D level 29.0 Symptoms in Children

Symptom	Description
Muscle Cramps	Vitamin D deficiency associated with rickets can lead to muscle cramps and spasms.
Vision Problems	Rickets can affect the eyes, leading to problems such as night blindness and other visual disturbances.
Delayed Growth	Children with rickets may experience slowed growth and development compared to their peers.
Muscle Weakness	Muscle weakness can result from compromised bone health and nutritional deficiencies associated with rickets.
Fatigue	Chronic pain and muscle weakness can result in increased fatigue and reduced activity levels.
Curvature of the Spine	Rickets can contribute to spinal deformities, such as scoliosis or kyphosis (excessive forward curvature of the upper spine).
Delayed Teething	Children with rickets might experience delays in the eruption of their teeth.
Bone Pain	Children with rickets often complain of bone pain, which can be especially pronounced in the legs, pelvis, and spine.
Brittle Nails	Rickets can cause nails to become brittle and prone to breaking.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.

Vitamin D level 29.0 Symptoms in Adults

Symptom	Description
Waddling Gait	A waddling gait may develop due to weakened hip and leg muscles associated with osteomalacia.
Fractures	Brittle and weak bones due to osteomalacia increase the risk of fractures even with minor injuries.
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.
Frequent Infections	Impaired bone health can weaken the immune system, leading to an increased susceptibility to infections.
Difficulty Climbing Stairs	Muscle weakness and bone pain can make climbing stairs difficult for those with osteomalacia.
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.
Tingling or Numbness	Nerve-related symptoms such as tingling or numbness can occur as a result of osteomalacia.
Depression	Chronic pain and physical limitations in osteomalacia can contribute to feelings of depression.

What additional risks do I face with a Vitamin D level of 29.0?

Level	Risk

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

Since your value of Vitamin D 29.0 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 : 29.0

• You get less than 1.75 hours of sunlight per day
• OR
• Insufficient Physical Activity + Insufficient Dietary Intake + Obesity
• Score : Your Vitamin D Insufficiency Score ranges between 9 and 13.

What is the treatment plan for a Vitamin D level of 29.0?

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 29.0 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.	1659 IU/d **(Represents a value in the range of 1000 - 2000, must be adjusted as per patient.)	2 months
Children 11–18 yrs.	2174 IU/d **(Represents a value in the range of 2000 - 4000, must be adjusted as per patient.)	2 months
