Vitamin D 7.0 ng/ml means : causes, sources, risks, treatment

In this article we discuss what a Vitamin D value of 7.0 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 7.0 mean?

A vitamin d level of 7.0 is considered to be deficient.

What is my Vitamin D level in SI units, for value of 7.0 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 7.0 is 17.5 nmol/L

Is a Vitamin D value of 7.0 considered low or high?

Based on your Vitamin D value of 7.0. you are classified as having a severe Vitamin D deficiency.

What are the sources of Vitamin D?

Food	How it helps with Vitamin D
Fortified cereals	Many cereals are enriched with Vitamin D to improve nutritional content.
Fortified orange juice	Certain brands of orange juice are fortified with Vitamin D to increase its nutritional value.
Fatty fish (salmon, mackerel, tuna)	Fatty fish are excellent sources of Vitamin D, particularly wild-caught species.
Bluefin tuna	Bluefin tuna is a fatty fish that contains high levels of Vitamin D.
Pork chops	Pork chops contain Vitamin D, particularly if they include the bone.
Trout	Trout can provide Vitamin D, particularly when caught in the wild.
Shrimp	Shrimp contain some Vitamin D, especially when consumed in larger quantities.
Tofu	Some tofu products are fortified with Vitamin D, especially those made from soy milk.
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.

What are the causes of Vitamin D deficiency?

Cause	Description
Certain genetic factors	Certain genetic variations can impact how the body processes and uses Vitamin D.
Celiac disease	An autoimmune disorder that damages the small intestine and impairs nutrient absorption.
Living in high latitudes	At higher latitudes, the angle of sunlight is lower, leading to reduced Vitamin D synthesis in the skin.
Certain types of cancer	Some cancers and their treatments can impact Vitamin D levels and metabolism.
Limited sunlight exposure	Insufficient exposure to sunlight, which is necessary for the skin to produce Vitamin D.
Multiple sclerosis	People with multiple sclerosis often have lower Vitamin D levels, although the relationship is complex.
Osteoporosis	Vitamin D is essential for bone health, and deficiency can contribute to conditions like osteoporosis.
Malabsorption disorders	Conditions like celiac disease can affect the body's ability to absorb Vitamin D from the digestive tract.
Inflammatory bowel disease	Conditions like Crohn's disease can impair nutrient absorption, including Vitamin D.
Strict vegan or vegetarian diet	Limited intake of animal products, which are sources of Vitamin D, can contribute to deficiency.

What symptoms will I experience with a Vitamin D of 7.0 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 7.0 the symptoms are enlisted in the table below:

Vitamin D level 7.0 Symptoms in Children

Symptom	Description
Dental Problems	Rickets can affect the development of teeth, leading to dental issues such as delayed eruption and enamel defects.
Delayed Teething	Children with rickets might experience delays in the eruption of their teeth.
Enlarged Joints	Swelling and tenderness in the joints can occur as a result of rickets.
Brittle Nails	Rickets can cause nails to become brittle and prone to breaking.
Difficulty Breathing	In severe cases, rickets can cause deformities of the ribcage, leading to difficulty in breathing and increased susceptibility to respiratory infections.
Fractures	Due to weakened bones, children with rickets are more prone to fractures even with minor injuries.
Weak or Soft Bones	Rickets can cause bones to become weak and soft, leading to an increased risk of fractures.
Fatigue	Chronic pain and muscle weakness can result in increased fatigue and reduced activity levels.
Muscle Cramps	Vitamin D deficiency associated with rickets can lead to muscle cramps and spasms.
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 7.0 Symptoms in Adults

Symptom	Description
Weight Loss	Some individuals with osteomalacia may experience weight loss due to the overall impact on health.
Difficulty Walking	Muscle and bone weakness can make walking and moving difficult for individuals with osteomalacia.
Bone Deformities	Osteomalacia can lead to bone deformities, such as bowed legs or a curvature of the spine.
Muscle Weakness	Muscle weakness can result from the lack of proper mineralization in the bones caused by osteomalacia.
Frequent Infections	Impaired bone health can weaken the immune system, leading to an increased susceptibility to infections.
Tingling or Numbness	Nerve-related symptoms such as tingling or numbness can occur as a result of osteomalacia.
Fractures	Brittle and weak bones due to osteomalacia increase the risk of fractures even with minor injuries.
Short Stature	In childhood cases, untreated osteomalacia can result in short stature and growth delays.
Difficulty Standing	Weak bones and muscles can make it challenging to stand for prolonged periods.
Difficulty Climbing Stairs	Muscle weakness and bone pain can make climbing stairs difficult for those with osteomalacia.

What additional risks do I face with a Vitamin D level of 7.0?

Your value is Less Than 25	Increased risk of fallsBischoff-Ferrari
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 8	More risk of cardiovascular mortality than those with a median vitamin d of 28Dobnig H
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 7.0 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 : 7.0

• 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 7.0?

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

Recommended Daily Dosing for Vitamin D in cases where the Vitamin D Level is < 10 ng/dl
