Vitamin D Chest Pain

Vitamin D Chest Pain

Vitamin D is integral for bone health, and severe deficiency can cause rickets in children and osteomalacia in adults. Although osteomalacia can cause severe generalized bone pain, there are only a few case reports of chest pain associated with vitamin D deficiency. We describe 2 patients with chest pain that were initially worked up for cardiac etiologies but were eventually diagnosed with costochondritis and vitamin D deficiency. Vitamin D deficiency is known to cause hypertrophic costochondral junctions in children ("rachitic rosaries") and sternal pain with adults diagnosed with osteomalacia. We propose that vitamin D deficiency may be related to the chest pain associated with costochondritis. In patients diagnosed with costochondritis, physicians should consider testing and treating for vitamin D deficiency.

Vitamin D is integral for bone health, and severe deficiency can cause rickets in children and osteomalacia in adults. Although

osteomalacia can cause severe generalized bone pain, there are only a few case reports of chest pain associated with vitamin D

deficiency. We describe 2 patients with chest pain that were initially worked up for cardiac etiologies but were eventually diagnosed

with costochondritis and vitamin D deficiency. Vitamin D deficiency is known to cause hypertrophic costochondral junctions in

children ("rachitic rosaries") and sternal pain with adults diagnosed with osteomalacia. We propose that vitamin D deficiency may

be related to the chest pain associated with costochondritis. In patients diagnosed with costochondritis, physicians should consider

testing and treating for vitamin D deficiency.

1. Introduction

Chest pain is a leading cause of ambulatory visits and ac-

counts for over 6 million emergency room visits in the United

States [1 ]. After serious cardiopulmonary conditions are

considered, musculoskeletal causes of chest pain, including

costochondritis, are commonly attributed to the final diag-

nosis [2 ,3 ]. Costochondritis is not clearly understood, but

may be related to inflammation of the costochondral

junctions associated with illness, coughing, or trauma [3 ].

Although there are a few reports of osteomalacia and vitamin

D deficiency associated with chest pain [4 6 ], we are not

aware of any literature reports of costochondritis associated

with vitamin D deficiency. This paper describes two cases

of patients with chest pain, eventually diagnosed with

costochondritis and vitamin D deficiency.

2. Cases

Case 1. A 35-year-old white female presented to the family

medicine clinic in Hawaii with complaints of chronic chest

pain for the last 3 years. She recently moved from North-

ern Virginia to Hawaii. Chart review was notable for a

negative cardiac workup, including a treadmill stress test,

and echocardiogram. Over the last 3 years, the diagnoses

of her chest pain included anxiety, esophageal reflux, and

costochondritis. In Hawaii, her exam was remarkable only

for tenderness to palpation over the left and right costo-

chondral junctions. Since she reported very little milk intake

or sun exposure, a serum 25-OH Vitamin D (25-OHD)

level was obtained and returned at 42 nmol/L (17 ng/mL),

consistent with deficiency. She was started on Vitamin D,

1000 international units (IU) daily. On 3-month followup,

her repeat serum 25-OHD was 72 nmol/L (29 ng/mL) and

she had complete resolution of her chest pain.

Case 2. A 42-year-old Asian female with historcarotid Dop-

pley of hypertension and hyperlipidemia presented to a

Hawaii emergency department with complaints of substernal

chest pain. She was admitted to the hospital for a rule-

out myocardial infarction protocol. In the hospital, she was

found to have marked tenderness along the left costochon-

dral junction. She did not routinely drink milk and despite

living in Hawaii, she reported little sun exposure due to

her work hours. After ruling out for myocardial infarction,

she was discharged with followup for a treadmill stress test,

which was normal. Prior to her discharge, a serum 25-

OHD level was drawn to rule out vitamin D deficiency.

2 Case Reports in Medicine

On followup, her vitamin D level returned 27 nmol/L

(11 ng/mL) and she continued to report chest pains. She was

started on oral Vitamin D2 50,000 IU once a week for 8 weeks

and maintained on 1,000 IU a day thereafter. Repeat 25-OHD

level 2 months later was 82 nmol/L (33 ng/mL). Her chest

pain resolved with treatment.

3. Discussion

In this paper, both patients had extensive workups done

with concern for cardiac disorders but were eventually di-

agnosed with costochondritis and vitamin D deficiency. We

hypothesize that these patients' costochondritis may have

been related to vitamin D deficiency. Vitamin D is integral

for bone health, and serum 25-OH vitamin D (25-OHD) is

predictive for body stores of vitamin D [7 9 ]. While there

is controversy over what defines deficient or optimal serum

levels of 25-OHD, levels less than 50nmol/L (20 ng/mL)

lead to increase in bone turnover markers and increase in

parathyroid hormone (PTH) [10 ]. Another study found that

defective bone mineralization was evident in patients with

serum 25-OHD less than 75 nmol/L (30 ng/mL) but none

above that threshold [11]. The recent Institute of Medicine

report found evidence that a serum 25-OHD level above

50 nmol/L (20 ng/mL) is generally su cient for bone health

for 97.5% of the population. Hence, a 25-OHD level less

than 50 nmol/L (20 ng/mL) is generally considered consistent

with vitamin D deficiency [7 ,8 ]. Severe vitamin D deficiency,

defined as a 25-OHD less than 25 nmol/L (10 ng/mL), can

cause rickets in children and osteomalacia in adults [12 ].

Rickets classically causes "bow legs" or "knock-knees" due

to disordered growth along weight-bearing bone. "Rachitic

rosaries" describes hypertrophied costochondral junctions in

relation to defective mineralization [13 ,14 ]. Osteomalacia,

the adult version of rickets, can cause di use bone pain.

Tenderness to the anterior tibia, sternum, and costochondral

joints can indicate osteomalacia and vitamin D deficiency

[14 ,15 ]. Although bone biopsy is the gold standard for

osteomalacia, it is not generally practiced. Bone pain and

vitamin D levels less than 25 nmol/L (10 ng/mL) are often

su cient for the clinical diagnosis of osteomalacia.

Although both patients did not have had levels less than

25 nmol/L (10 ng/mL) to suggest osteomalacia, we theorize

that milder forms of vitamin D deficiency can cause a

spectrum of pain along the sternum and costochondral

junctions similar to patients with rickets and osteomala-

cia. Costochondritis continues to be a poorly defined entity

but may represent a milder, earlier form of osteomalacia

associated with higher serum 25-OHD levels. Importantly,

osteomalacia and vitamin D deficiency may not be consid-

ered when a patient presents with complaints consistent with

costochondritis, as testing for vitamin D deficiency in these

patients has not been reported, nor is it routine.

A review of the literature revealed no reported cases of

costochondritis associated with vitamin D deficiency, and

only a few case reports of chest pain associated with vitamin

D deficiency. One case described chronic chest and leg

pain of 2 years duration in a 34-year-old female [4 ]. After

two years of conservative treatment with anti-inflammatory

medications, she was eventually diagnosed with osteomalacia

associated with aluminum-containing antacid use. Alumi-

num containing antacids may cause osteomalacia by binding

to phosphate, causing a negative phosphate balance and

eventual disordered bone growth. However, there was no

serum 25-OH vitamin D (25-OHD) level measured to sup-

port the diagnosis of osteomalacia. She improved with vita-

min D supplementation and decreased antacid use. Another

case reported a 37-year-old Indian living in Germany who

was subsequently diagnosed with vitamin D deficiency and

osteomalacia. Chest pain was the only presenting symptom.

His 25-OHD level was undetectable. He was started on

high-dose vitamin D and then maintenance vitamin D with

resolution of his chest pain [5 ]. Lastly, a 21-year-old Turkish

female living in Germany presented with left-sided chest

pain with unremarkable electrocardiogram, troponin and

d-dimer [6 ]. Her 25-OHD level was 9 nmol/L (4 ng/mL),

and she was diagnosed with osteomalacia causing her chest

pain. Treatment with vitamin D, calcium, and calcitonin

resolved her symptoms in two months. These case reports are

suggestive of osteomalacia and severe vitamin D deficiency

as the cause of chest pains. It is possible that the spectrum of

bone pain, including costochondritis, may be correlated to

the degree of vitamin D deficiency.

In our paper, both patients were at significant risk for

vitamin D deficiency despite living in an area with abundant

sunshine. Vitamin D can only be obtained through ultravi-

olet light exposure, vitamin-D-rich foods, and supplementa-

tion. Both patients reported little to no milk intake, no other

vitamin supplementation, and little sun exposure, putting

them at high risk for deficiency. The IOM recently increased

the recommended daily allowance (RDA) of vitamin D

for adults from 400 IU to a minimum of 600 IU in order

to maintain 25-OHD levels above 50nmol/L (20 ng/mL)

for 97.5% of the population [7 ]. However, other expert

recommendations have suggested much higher levels of

vitamin D, ranging from 400 to 2000 IU daily to maintain

adequate serum 25-OHD; depending on risk factors present

[8 ,9 ]. Sun exposure can provide the most e cient means

of maintaining vitamin D stores; however, dark-skinned

individuals absorb less ultraviolet radiation from sunlight

and thus convert less 7-dehydrocholesterol into vitamin D.

People living at higher latitudes are at increased risk for

deficiency, but studies show that even in areas with adequate

sunshine, vitamin D deficiency can be highly prevalent [16 ,

17].

Our paper has clear limitations. With prevalence of

vitamin D deficiency reported to be up to 36% in young

adults [12 ], costochondritis may be merely an unrelated

association. However, with treatment of deficiency and

normalization of their serum vitamin D, both patients' cos-

tochondritis improved, further supporting vitamin D defi-

ciency as a potential cause of their costochondritis. The

improvement of symptoms may also be attributed to self-

limited costochondritis rather than the vitamin D sup-

plementation. However, it is notable that once adequate

treatment was initiated, no further cases of chest pains have

been reported—including the patient who had 3 years of

chronic chest pain. This further strengthens our hypothesis

Case Reports in Medicine 3

that vitamin D deficiency may be a cause of costochondritis.

We recommend further prospective studies, specifically in

primary care, to help elucidate the association of vitamin D

deficiency and costochondritis.

4. Conclusion

In patients with costochondritis, or bony sternal pain, physi-

cians should consider vitamin D deficiency and osteomalacia

and elicit any risk factors for deficiency. Patients with

costochondritis who are at risk for vitamin D deficiency

the association of costochondritis and vitamin D deficiency

are warranted.

GİRİŞ Göğüs ağrısı, dünya çapında en yaygın tıbbi yardım alma nedenlerinden birisi olarak bilinmektedir (1). Birinci basamak sağlık kuruluşlarına gelen hastaların %1 ile %3'ünü bu şikayet ile gelen hastalar oluşturur. Bu başvuruların hemen hemen yarısı kas iskelet sistemi ile ilişkili hastalıklardan kaynaklanan göğüs ağrısıdır (2). Kardiyovasküler, pulmoner, gastroenterolojik nedenli ve psikojenik faktörler de göğüs ağrısına neden olabilirler. Ayrıca omuz eklem ku-şağındaki patolojiler, servikal, torakal omurga ve diyafram alt bölgesi anatomik yapılarındaki olası patolojiler göğüs bölgesine yansıyan ağrıya neden olabilir (3). Göğüs ağrısının nedenleri arasında kalp, akciger ve ozefagus gibi intratorasik yapilar olabilir. Kalp gibi torakal bölge lokalizasyonlu yapilardaki agriyi ileten serbest sinir uc-lari, ayni seviyede spinal kord dorsal boynuzda cilt, kas ve eklemlerden afferent uyariyi alan internöronlarla sinaps yapar.

Bu nedenle, göğüs ağrısının nedeninin kas-iskelet sistemi kaynaklı mı ya da visseral bir organ kökenli mi olduğunu kesin olarak tanımlamak zor olabilir. Bu nedenle göğüs ağrısı tanısı ile başvuran olgularda kas iskelet sistemi kaynaklı ol-duğu düşünülmeden önce olası diğer nedenlerin ekarte edilmesi gereklidir (3,4).

The emergence of new data suggests that the benefits of Vitamin D extend beyond healthy bones. This paper looks at Vitamin D and its role in the aetiology and maintenance of chronic pain states and associated comorbidities. The interfaces between pain and Vitamin D and the mechanisms of action of Vitamin D on pain processes are explored. Finally the association between Vitamin D and pain comorbidities such as sleep and depression is investigated. The paper shows that Vitamin D exerts anatomic, hormonal, neurological, and immunological influences on pain manifestation, thereby playing a role in the aetiology and maintenance of chronic pain states and associated comorbidities. More research is necessary to determine whether Vitamin D is useful in the treatment of various pain conditions and whether or not the effect is limited to patients who are deficient in Vitamin D.

Background: In children, vitamin D deficiency can result in the hypertrophy of costochondral junctions and sternal pain. Objectives: In this study, we aimed at determining the correlation between children's vitamin D status and costochondritis. Methods: This cross-sectional study included a control group (100 healthy children) and a study group (100 children with costochondritis). Examination of patients included chest radiography, physical examination, history-taking, electrocardiography, echocardiography, and serum measurement of 25-hydroxyvitamin D, phosphorus, calcium, and alkaline phosphatase. The Chi-square test, Spearman's correlation test, and independent samples t-test were also performed for analyzing the data. Results: The groups showed no significant difference regarding age, gender, or body mass index (P = 0.315, P = 0.671, and P = 0.097, respectively). The history of patients experiencing idiopathic chest pain showed cardiac disease in 13% of their families, without report of death in the family. The pain was mainly located in the left precordium (64%), followed by the right precordium and the midsternal region (32% and 18%, respectively). A significantly lower level of 25-OHD was found in the study group than in the control group (P < 0.0001). Based on the findings, the groups were not significantly different regarding the evaluated biochemical parameters, except for alkaline phosphatase (P = 0.007). The results showed that pain duration and episodes were significantly associated with vitamin D insufficiency (r = -0.621, P = 0.002; r = -0.213, P = 0.021, respectively). Conclusions: Vitamin D insufficiency should be considered in costochondritis. Also, pain duration and episodes have associations with vitamin D insufficiency. This finding emphasizes the necessity of evaluating nutritional parameters in children with non-cardiac chest pain.

Costochondritis (ChC), especially chronic ChC, typically manifests as spontaneous vague pain in anterior chest area and often occurs in adolescents for unknown reasons; it has prevented many collegiate athletes from participating in physical training and competitions. A 21-year-old female collegiate taekwondo athlete suffering from chronic chest pain was sent by her coaches for diagnosis and treatment. Seated motion palpation was used to identify spontaneous and motion-involved pain areas. Palpation in the supine position was used to initially rule out breast diseases. X-ray, electrocardiogram, and cardiac Doppler ultrasound were used in conjunction with myocardial enzyme testing to rule out lung and cardiovascular diseases. The patient was treated using herbal medicines applied via an external patch. The medicine was comprised of Rhizoma Corydalis and borneol, and the treatment lasted for seven weeks. For five weeks patches were applied at a frequency of two or three times per day, followed by a two-week period of once per day. The patient reported that the pain was relieved after two weeks of external herb use, and the autonomic chest pain had resolved. Re-examination after one month showed that her upper limb range of motion was close to normal, and her psychological burden had almost disappeared. It is possible to seek more active medicinal treatment and more practical external products for young athletes who is suffering chronic ChC that affects the sport training and competitive performances.

Osteomalacia is a bone disease, characterized by the inability of newly formed bone matrix to undergo mineralization. The most common symptoms are generalized bone pain and widespread body pain, while some patients are asymptomatic. Restless leg syndrome (RLS) is a sensory-motor neurological disease. The main symptoms are abnormal sensations in the legs and dysesthesia. Symptoms worsen at night and affect sleep quality. We present a case of a woman with a progressive hip and feet pain. Many biochemical, clinical, and radiological tests were performed for diagnosis. All were found to be normal. The patient was diagnosed as having RLS. 0.25 mg pramipexole was given for treatment. Patient symptoms patient escalated over six months. The patient was reassessed after six months. Vitamin D levels had not been previously examined. We found low vitamin D and calcium levels, as well as pseudofractures in radiography. The diagnosis was changed to osteomalacia. Vitamin D and calcium treatment were started. Symptoms began to regress from the first week of treatment.

Wir stellen eine 21-jährige aus der Türkei stammende muslimische Patientin mit atypischen links-thorakalen Schmerzen vor. Klinisch und laborchemisch konnte die Diagnose einer Osteomalazie aufgrund mangelnder Sonnenexposition u.a. wegen traditioneller Kleidung gestellt werden. Unter Vitamin-D- und Kalziumsubstitution normalisierten sich sowohl Klinik als auch das Labor. Bei muslimisch gekleideten Frauen mit Knochenschmerzen sollte an eine Osteomalazie gedacht werden. Ob prophylaktisch eine Vitamin-D- und Kalziumsubstitution durchgeführt werden sollte, wird in der Literatur kontrovers diskutiert und kann u.a. von der anamnestisch erhobenen täglichen Kalziumaufnahme der Patientin abhängig gemacht werden.

Lack of sun exposure is widely accepted as the primary cause of epidemic low vitamin D status worldwide. However, some individuals with seemingly adequate UV exposure have been reported to have low serum 25-hydroxyvitamin D [25(OH)D] concentration, results that might have been confounded by imprecision of the assays used. The aim was to document the 25(OH)D status of healthy individuals with habitually high sun exposure. This study was conducted in a convenience sample of adults in Honolulu, Hawaii (latitude 21 degrees ). The study population consisted of 93 adults (30 women and 63 men) with a mean (sem) age and body mass index of 24.0 yr (0.7) and 23.6 kg/m(2) (0.4), respectively. Their self-reported sun exposure was 28.9 (1.5) h/wk, yielding a calculated sun exposure index of 11.1 (0.7). Serum 25(OH)D concentration was measured using a precise HPLC assay. Low vitamin D status was defined as a circulating 25(OH)D concentration less than 30 ng/ml. Mean serum 25(OH)D concentration was 31.6 ng/ml. Using a cutpoint of 30 ng/ml, 51% of this population had low vitamin D status. The highest 25(OH)D concentration was 62 ng/ml. These data suggest that variable responsiveness to UVB radiation is evident among individuals, causing some to have low vitamin D status despite abundant sun exposure. In addition, because the maximal 25(OH)D concentration produced by natural UV exposure appears to be approximately 60 ng/ml, it seems prudent to use this value as an upper limit when prescribing vitamin D supplementation.

The objective was to provide guidelines to clinicians for the evaluation, treatment, and prevention of vitamin D deficiency with an emphasis on the care of patients who are at risk for deficiency. The Task Force was composed of a Chair, six additional experts, and a methodologist. The Task Force received no corporate funding or remuneration. Consensus was guided by systematic reviews of evidence and discussions during several conference calls and e-mail communications. The draft prepared by the Task Force was reviewed successively by The Endocrine Society's Clinical Guidelines Subcommittee, Clinical Affairs Core Committee, and cosponsoring associations, and it was posted on The Endocrine Society web site for member review. At each stage of review, the Task Force received written comments and incorporated needed changes. Considering that vitamin D deficiency is very common in all age groups and that few foods contain vitamin D, the Task Force recommended supplementation at suggested daily intake and tolerable upper limit levels, depending on age and clinical circumstances. The Task Force also suggested the measurement of serum 25-hydroxyvitamin D level by a reliable assay as the initial diagnostic test in patients at risk for deficiency. Treatment with either vitamin D(2) or vitamin D(3) was recommended for deficient patients. At the present time, there is not sufficient evidence to recommend screening individuals who are not at risk for deficiency or to prescribe vitamin D to attain the noncalcemic benefit for cardiovascular protection.

This article summarizes the new 2011 report on dietary requirements for calcium and vitamin D from the Institute of Medicine (IOM). An IOM Committee charged with determining the population needs for these nutrients in North America conducted a comprehensive review of the evidence for both skeletal and extraskeletal outcomes. The Committee concluded that available scientific evidence supports a key role of calcium and vitamin D in skeletal health, consistent with a cause-and-effect relationship and providing a sound basis for determination of intake requirements. For extraskeletal outcomes, including cancer, cardiovascular disease, diabetes, and autoimmune disorders, the evidence was inconsistent, inconclusive as to causality, and insufficient to inform nutritional requirements. Randomized clinical trial evidence for extraskeletal outcomes was limited and generally uninformative. Based on bone health, Recommended Dietary Allowances (RDAs; covering requirements of ≥97.5% of the population) for calcium range from 700 to 1300 mg/d for life-stage groups at least 1 yr of age. For vitamin D, RDAs of 600 IU/d for ages 1-70 yr and 800 IU/d for ages 71 yr and older, corresponding to a serum 25-hydroxyvitamin D level of at least 20 ng/ml (50 nmol/liter), meet the requirements of at least 97.5% of the population. RDAs for vitamin D were derived based on conditions of minimal sun exposure due to wide variability in vitamin D synthesis from ultraviolet light and the risks of skin cancer. Higher values were not consistently associated with greater benefit, and for some outcomes U-shaped associations were observed, with risks at both low and high levels. The Committee concluded that the prevalence of vitamin D inadequacy in North America has been overestimated. Urgent research and clinical priorities were identified, including reassessment of laboratory ranges for 25-hydroxyvitamin D, to avoid problems of both undertreatment and overtreatment.

The 2002 guidelines for the management of osteoporosis published by Osteoporosis Canada1 identified adequate vitamin D status, in addition to calcium from diet or supplements, as essential for the prevention of osteoporosis. Recent large clinical trials and meta-analyses have expanded our knowledge of the role of vitamin D in fractures, falls and other health outcomes, as well as its effect on disorders such as diabetes mellitus, autoimmune and infectious diseases, malignancies and cardiovascular disease. Current Canadian recommendations for "adequate intake" and "tolerable upper level" of vitamin D, which are more than 10 years old, were derived mainly from early nutritional science estimates of the minimal intake necessary to prevent florid deficiency states (rickets or osteomalacia). However, these levels have never been supported by adequately conducted dose-finding studies.2 This review is an update to the 2002 recommendations on vitamin D and is specific for adults, excluding times of pregnancy and lactation.

Ce travail presente le tableau clinique d'une osteomalacie illustree par l'anamnese, le status et les examens paracliniques d'un patient âge de 37 ans avec des douleurs thoraciques. Cette maladie s'est developpee en raison d'un manque d'exposition au soleil pour des raisons ethniques (port d'une longue barbe et d'un turban en tant que sikh croyant) avec deficit en vitamine D.

Costochondritis, an inflammation of costochondral junctions of ribs or chondrosternal joints of the anterior chest wall, is a common condition seen in patients presenting to the physician's office and emergency department. Palpation of the affected chondrosternal joints of the chest wall elicits tenderness. Although costochondritis is usually self-limited and benign, it should be distinguished from other, more serious causes of chest pain. Coronary artery disease is present in 3 to 6 percent of adult patients with chest pain and chest wall tenderness to palpation. History and physical examination of the chest that document reproducible pain by palpation over the costal cartilages are usually all that is needed to make the diagnosis in children, adolescents, and young adults. Patients older than 35 years, those with a history or risk of coronary artery disease, and any patient with cardiopulmonary symptoms should have an electrocardiograph and possibly a chest radiograph. Consider further testing to rule out cardiac causes if clinically indicated by age or cardiac risk status. Clinical trials of treatment are lacking. Traditional practice is to treat with acetaminophen or anti-inflammatory medications where safe and appropriate, advise patients to avoid activities that produce chest muscle overuse, and provide reassurance.

Parathyroid hormone (PTH) is only one measurable index of skeletal health, and we reasoned that a histomorphometric analysis of iliac crest biopsies would be another and even more direct approach to assess bone health and address the required minimum 25-Hydroxyvitamin D [25(OH)D] level. A cohort from the northern European population with its known high prevalence of vitamin D deficiency therefore would be ideal to answer the latter question. We examined 675 iliac crest biopsies from male and female individuals, excluding all patients who showed any signs of secondary bone diseases at autopsy. Structural histomorphometric parameters, including osteoid indices, were quantified using the Osteomeasure System according to ASBMR standards, and serum 25(OH)D levels were measured for all patients. Statistical analysis was performed by Student's t test. The histologic results demonstrate an unexpected high prevalence of mineralization defects, that is, a pathologic increase in osteoid. Indeed, 36.15% of the analyzed patients presented with an osteoid surface per bone surface (OS/BS) of more than 20%. Based on the most conservative threshold that defines osteomalacia at the histomorphometric level with a pathologic increase in osteoid volume per bone volume (OV/BV) greater than 2% manifest mineralization defects were present in 25.63% of the patients. The latter were found independent of bone volume per trabecular volume (BV/TV) throughout all ages and affected both sexes equally. While we could not establish a minimum 25(OH)D level that was inevitably associated with mineralization defects, we did not find pathologic accumulation of osteoid in any patient with circulating 25(OH)D above 75 nmol/L. Our data demonstrate that pathologic mineralization defects of bone occur in patients with a serum 25(OH)D below 75 nmol/L and strongly argue that in conjunction with a sufficient calcium intake, the dose of vitamin D supplementation should ensure that circulating levels of 25(OH)D reach this minimum threshold (75 nmol/L or 30 ng/mL) to maintain skeletal health.
