Vitamin D Can Effectively Treat Fibromyalgia

New research suggests vitamin D supplements can reduce pain and may be a cost-effective alternative, or an adjunct to other treatment, for individuals with fibromyalgia syndrome (FMS).
The supplementation is helpful for fibromyalgia patients suffering from low vitamin D levels, say researchers in the journal PAIN®.

In addition to pain and fatigue, individuals diagnosed with FMS may experience sleep disorders, morning stiffness, poor concentration, and occasionally mild-to-severe mental symptoms such as anxiety or depression.

The condition can have a significant impact on the patient’s quality of life, resulting in loss of employment and/or withdrawal from social life.

There is no cure, and no treatment will address all of the symptoms, but some symptoms may be alleviated by physical therapy, cognitive behavioral therapy, temporary drug therapy (such as amitriptyline, duloxetine, or pregabaline) and multimodal therapies.

Calcifediol is a prehormone produced in the liver by the enzyme cholecalciferol (vitamin D3).
Calcifediol is then converted to calcitriol (1,25-(OH)2D3), which is the active form of vitamin D. The concentration of calcifediol in blood is considered the best indicator of vitamin D status.
Researchers hypothesized that vitamin D supplementation would reduce the degree of chronic pain experienced by FMS patients with low levels of calcifediol and also might improve other symptoms.

“Low blood levels of calcifediol are especially common in patients with severe pain and fibromyalgia. But although the role of calcifediol in the perception of chronic pain is a widely discussed subject, we lack clear evidence of the role of vitamin D supplementation in fibromyalgia patients,” said lead investigator Florian Wepner, M.D.

“We therefore set out to determine whether raising the calcifediol levels in these patients would alleviate pain and cause a general improvement in concomitant disorders.”
In a randomized controlled trial, 30 women with FMS with low serum calcifediol levels (below 32ng/ml) were randomized to a treatment or control group.

The goal for the treatment group was to achieve serum calcifediol levels between 32 and 48ng/ml for 20 weeks via oral cholecalciferol supplements.

Serum calcifediol levels were reevaluated after five and 13 weeks, and the dose was reviewed based on the results. The calcifediol levels were measured again 25 weeks after the start of the supplementation, at which time treatment was discontinued, and after a further 24 weeks without supplementation.

Twenty-four weeks after supplementation was stopped, a marked reduction in the level of perceived pain occurred in the treatment group.
Between the first and the 25th week on supplementation, the treatment group improved significantly on a scale of physical role functioning, while the placebo group remained unchanged.

The treatment group also scored significantly better on a Fibromalgia Impact Questionnaire (FIQ) on the question of “morning fatigue.” However, there were no significant alterations in depression or anxiety symptoms.

“We believe that the data presented in the present study are promising. FMS is a very extensive symptom complex that cannot be explained by a vitamin D deficiency alone.
“However, vitamin D supplementation may be regarded as a relatively safe and economical treatment for FMS patients and an extremely cost-effective alternative or adjunct to expensive pharmacological treatment as well as physical, behavioral, and multimodal therapies,” said Wepner.

“Vitamin D levels should be monitored regularly in FMS patients, especially in the winter season, and raised appropriately.”

nutraMetrix Isotonix Vitamin D with K2 contains vitamin D3, the metabolically active form of vitamin D, along with vitamin K2, a form of vitamin K which supports vascular health and calcium utilization. Vitamin D plays an important role in bone health, heart health and immune support, while working with vitamin K to support normal absorption of calcium and promote healthy arteries. nutraMetrix Isotonix Vitamin D is the first of its kind to deliver both of these powerful vitamins with isotonic delivery.

Vitamin K is included in nutraMetrix Isotonix Vitamin D with K2 because of its unique partnership with vitamin D. Vitamins K and D work together to support calcium absorption and utilization. Vitamin K supports the normal delivery of calcium to the bones and promotes healthy arteries.
At least two naturally-occurring forms of vitamin K have been identified and are known as K1 and K2. While there are many similarities between these two forms of vitamin K, they are distinguished by their important differences. The most significant difference between K1 and K2 is their chemical structure which results in different pharmacokinetic properties. Vitamin K1 is retained primarily in the liver where, at high doses, it may interfere with the action of warfarin and other anticoagulant medications.

Vitamin K2 has a different mechanism of action. It is transported primarily to bones and blood vessels. Vitamin K2 helps to maintain bone mass, support calcium utilization and promote elasticity of blood vessels.

Some studies have concluded that vitamin K2 does not interfere with anticoagulant medications.* However, most products containing vitamin K (including K1 and/or K2) warn users taking anticoagulants not to take the product. If you are currently taking warfarin or another anticoagulant medication, you should consult your physician before taking any product containing vitamin K1 or K2.

Isotonix dietary supplements are delivered in an isotonic solution. This means that the body has less work to do to obtain maximum absorption of the nutrients. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and rapidly absorb into the bloodstream. With Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.
