Vitamin D is often called the 'sunshine vitamin' because it is produced by the body when exposed to sunlight. It is also available as a supplement. Vitamin D deficiency is associated with muscle pain and weakness, and can lead to an increased risk of falls. Low vitamin D levels have been linked to non-specific muscle, bone, or joint pain, muscle weakness or fatigue, fibromyalgia syndrome, and rheumatic disorders. Studies have shown that vitamin D therapy can help alleviate chronic muscle, bone, and joint pain. However, recent research suggests that vitamin D supplementation does not reduce statin-associated muscle pain.

What You'll Learn

Vitamin D deficiency and muscle pain
Vitamin D is sometimes called the "sunshine vitamin" because our bodies naturally produce it when exposed to sunlight. It is not as easily absorbed into the bloodstream from food sources. Vitamin D deficiency is very common, and symptoms include muscle weakness, pain, and aches in both children and adults.
Up to 93% of people reporting nonspecific musculoskeletal pain are deficient in vitamin D. A study found that 100% of African Americans, East Africans, Hispanics, and American Indians had deficient levels of vitamin D. Another study reported that 88% of Danish women of Arab descent who presented with muscle pains and weakness were severely vitamin D deficient.
Vitamin D therapy has been shown to alleviate chronic muscle, bone, and joint aches and pains of various types. In a large study of 360 female patients with chronic back pain, vitamin D therapy produced symptomatic improvement in 96% of all patients and in 100% of those with the most severe deficiencies. In another study, aches, pains, and extreme muscle weakness were resolved by vitamin D supplementation in five patients who had been confined to wheelchairs. Four of the patients reportedly became fully mobile upon normalization of their vitamin D concentrations.
However, one recent study found that vitamin D supplementation did not reduce statin-associated muscle pain. Patients who take statins to lower high cholesterol often complain of muscle pains, which can lead them to stop the medication and put them at greater risk of heart attack or stroke. While non-randomized studies have reported vitamin D to be an effective treatment for statin-associated muscle symptoms, the first randomized clinical trial was large enough to rule out any important benefits.

Vitamin D therapy for chronic pain
Vitamin D therapy has been proposed as a potential treatment for chronic pain. Chronic pain, persisting for more than three months, often lacks a clear cause and affects a significant portion of the population. Research has linked inadequate vitamin D levels to various types of chronic pain, including nonspecific muscle, bone, or joint pain, fibromyalgia syndrome, rheumatic disorders, and osteoarthritis. Vitamin D supplementation has been suggested as a possible solution for those unresponsive to other treatments.
Vitamin D deficiency is prevalent, affecting various ethnic groups and age ranges. It is especially common among individuals with darker skin due to the interference with the production of vitamin D3 in the skin. Low vitamin D levels are associated with muscle weakness and an increased risk of falls. In addition, vitamin D-deficient rats exhibited deep muscle hypersensitivity without cutaneous hypersensitivity, indicating a potential link to pain.
Several studies have explored the potential of vitamin D therapy for chronic pain. One study involving 33 patients with chronic back pain found that two-thirds experienced complete symptom resolution with vitamin D therapy, while 18% achieved partial pain relief. Another study by Gloth and colleagues observed significant improvements in hyperesthesia symptoms with vitamin D supplementation. Additionally, vitamin D supplementation has been linked to improvements in depression, anxiety, and seasonal affective disorder, which are often associated with chronic pain.
While the evidence suggests a potential role for vitamin D therapy in chronic pain management, it is not a universally effective solution. Some studies have found no connection between vitamin D and chronic pain, and the overall evidence is considered inconclusive. High-quality randomized controlled trials are lacking, and further research is needed to establish the effectiveness of vitamin D supplementation in chronic pain treatment.
Vitamin D supplementation is generally safe, inexpensive, and has few side effects. However, it is important to note that individuals at risk for vitamin D deficiency may require higher doses, and specific guidelines for chronic pain populations are currently lacking. Nonetheless, given the prevalence of vitamin D deficiency and its potential benefits in chronic pain management, it is recommended that individuals with chronic pain consider getting their vitamin D levels checked and discuss appropriate supplementation with their healthcare providers.

Vitamin D and statin-associated muscle pain
Vitamin D deficiency is a common problem affecting both children and adults. It is estimated that 90% of the vitamin D required by our bodies is produced by exposure to sunlight. Therefore, factors such as increased melanin pigmentation and sunscreen use can lead to a deficiency.
Vitamin D deficiency has been linked to muscle weakness and muscle aches and pains in both children and adults. Up to 93% of those reporting nonspecific musculoskeletal pain are deficient in vitamin D. In a study, rats receiving vitamin D-deficient diets for 2–4 weeks showed mechanical deep muscle hypersensitivity, accompanied by balance deficits.
Some clinicians have recommended vitamin D supplements to ease the muscle aches associated with statin use. Statins are drugs used to lower high cholesterol levels, but they often cause muscle pains, leading patients to stop their medication and increasing their risk of heart attack or stroke.
However, a recent randomized, double-blind clinical trial found that vitamin D supplementation did not reduce muscle pain associated with statin use. The study, led by Mark Hlatky, included 2,083 participants who ingested either 2,000 units of vitamin D supplements or a placebo daily. Over 4.8 years of follow-up, statin-related muscle pain was reported by 31% of participants in both the vitamin D and placebo groups.
While vitamin D supplementation may not be effective for statin-associated muscle pain, it is still a safe, inexpensive, and generally beneficial prophylactic for muscle pain in general.

Vitamin D deficiency and musculoskeletal pain
Vitamin D deficiency is a common problem affecting both children and adults. It has been linked to various medical issues, including musculoskeletal pain. This pain can manifest as muscle weakness, aches, and pains, and can be especially prominent in the hip and knee joints of adults over 50. In some cases, vitamin D deficiency can lead to chronic musculoskeletal pain, which can have significant social and economic impacts.
Vitamin D is often referred to as the "sunshine vitamin" because our bodies naturally produce it when exposed to sunlight. However, due to various factors, many people do not get enough vitamin D from sunlight alone, and dietary supplementation may be necessary. The UK government and the NHS recommend that everyone over the age of one consider taking a vitamin D supplement during the autumn and winter months when natural sunlight is less abundant. This is particularly important for individuals with darker skin, as increased melanin pigmentation can interfere with the skin's production of vitamin D.
The link between vitamin D deficiency and musculoskeletal pain has been supported by various studies. In one study, rats fed vitamin D-deficient diets for 2-4 weeks exhibited mechanical deep muscle hypersensitivity, balance deficits, and increased nociceptor axons. Similarly, Bischoff et al. observed that adults with vitamin D deficiency experienced muscle weakness and an increased risk of falling. Additionally, Glerup et al. found that 88% of Danish women of Arab descent who presented with muscle pains and weakness were severely vitamin D deficient.
Vitamin D supplementation has been proposed as a potential treatment for musculoskeletal pain associated with vitamin D deficiency. This is supported by clinical studies demonstrating the benefits of vitamin D therapy in alleviating chronic muscle, bone, and joint pain. In one large study, vitamin D therapy resulted in symptomatic improvement in 96% of female patients with chronic back pain, with complete resolution of symptoms in those with severe 25(OH)D deficiencies. Another study of patients with chronic back pain and/or multiple somatic pain symptoms found that two-thirds of the subjects experienced a resolution of all symptoms after vitamin D therapy.
While vitamin D supplementation has shown promise in treating musculoskeletal pain related to vitamin D deficiency, it is important to note that it may not be effective in all cases. For example, a recent randomized, double-blind, placebo-controlled trial found that vitamin D supplementation did not reduce statin-associated muscle pain.

Vitamin D deficiency and muscle weakness
Vitamin D deficiency is a common problem affecting many people of all ages and races. It is estimated that 90% of our required vitamin D comes from exposure to sunlight. Therefore, people with darker skin are at a higher risk of vitamin D deficiency as melanin pigmentation and sunscreen use can interfere with the production of vitamin D.
Vitamin D deficiency has been linked to nonspecific muscle, bone, or joint pain, muscle weakness or fatigue, and fibromyalgia syndrome. Patients with osteomalacia due to vitamin D deficiency often experience a dull, unrelenting aching sensation in their bones. This can be misdiagnosed as fibromyalgia. A physical examination that includes applying minimal pressure to the sternum, anterior tibia, or radius and ulna can help diagnose osteomalacia.
In a study of 360 female patients with chronic back pain, vitamin D therapy improved symptoms in 96% of patients and resolved symptoms in 100% of those with severe vitamin D deficiencies. Another study of 33 patients with chronic back pain found that vitamin D therapy led to a resolution of all symptoms in two-thirds of the subjects. Additionally, a case series reported that aches, pains, and extreme muscle weakness were resolved by vitamin D supplementation in five patients who had been confined to wheelchairs. Four of these patients regained full mobility upon normalization of their vitamin D concentrations.
Vitamin D therapy has also been suggested as a treatment for muscle pain associated with statin therapy. However, a recent randomized, double-blind, placebo-controlled trial found that vitamin D supplementation did not reduce statin-associated muscle pain. Despite this, vitamin D supplementation is generally safe, inexpensive, and has few side effects. It may still be beneficial for preventing and treating other types of muscle pain and weakness.

Frequently asked questions
Vitamin D deficiency is associated with muscle pain and weakness. However, vitamin D supplementation has been shown to alleviate chronic muscle, bone, and joint aches and pains.
Vitamin D deficiency can lead to selective alterations in target innervation, resulting in presumptive nociceptor hyperinnervation of skeletal muscle, contributing to muscular hypersensitivity and pain.
A simple blood test can determine if you have a vitamin D deficiency. Symptoms of vitamin D deficiency include muscle weakness, fatigue, anxiety, and paresthesia (numbness, tingling, prickling, or burning).
Vitamin D is sometimes called the "sunshine vitamin" because your body naturally produces vitamin D when exposed to sunlight. Vitamin D supplements are also effective and recommended during seasons with less sunshine.
