High doses of vitamin D provide clinically modest but statistically significant benefits for adults with multiple sclerosis (MS), according to a meta-analysis of published clinical trials. The study found patients who took the supplement saw reductions in disability scores, relapses, and new lesion formation. Those who took vitamin D for…

A high dose cholecalciferol, a form of vitamin D, significantly reduced the risk of further disease activity in people with clinically isolated syndrome (CIS), published findings from a Phase 3 trial show. Vitamin D was similarly effective for reducing disease activity among a subgroup of participants who would…

Taking high-dose cholecalciferol (vitamin D) as a supplement is safe and can nearly double the time it takes for people with clinically isolated syndrome (CIS), a first manifestation of neurological symptoms suggestive of multiple sclerosis (MS), to experience new disease activity. That’s according to data from D-Lay-MS…

Vitamin D supplements were associated with less severe disease in a rat model of progressive multiple sclerosis (MS), but male rats tended to experience greater benefits than did females, a study into disease-related sex differences reports. This higher overall benefit may be due to nerve cells in males being…

Taking a high-dose vitamin D supplement as an add-on to standard treatment for multiple sclerosis (MS) doesn’t slow the development of new lesions, a sign that the brain or spinal cord have been damaged, according to a meta-analysis study. Vitamin D also had no…

Low blood levels of vitamin D are tied to poorer cognitive skills and more severe disability in people with multiple sclerosis, researchers in Italy report. “Our study showed that [vitamin D] levels are associated with cognitive function in MS, as already well demonstrated in the general population and in…

Vitamin D reduced the signs of inflammation and nerve damage in a rat model of progressive multiple sclerosis (MS), a study shows. Low levels of the vitamin have been extensively linked with a higher risk of developing relapsing forms of the disease, but studies of vitamin D supplementation in…

In this installment of our “Expert Voices” series, Multiple Sclerosis News Today asked Dr. Susan Payrovi, MD, to answer some of your questions about seeking functional medicine care with multiple sclerosis (MS). Payrovi is a clinical assistant professor at Stanford’s Department of Anesthesiology, Perioperative and Pain Medicine. She practices…

No Link Between MS Severity, Vitamin D-related Mutations: Study Several studies over the years have indicated that there could be a link between a person’s vitamin D level and the risk of multiple sclerosis (MS). This study is slightly different. Researchers looked at whether genetic variations related to vitamin…

A number of genetic variations related to vitamin D metabolism were not significantly associated with the severity of multiple sclerosis (MS), according to a recent study. The study, “Role of Multiple Vitamin D-Related Polymorphisms in Multiple Sclerosis Severity: Preliminary Findings,” was published in Genes. In MS, the body’s immune…

People with high levels of free vitamin D in circulation before the age of 20 have a lower risk of developing multiple sclerosis (MS) later in life, a new study suggests. A significantly lower risk was also observed among people who, at ages 30–39, had elevated levels of a…

In this installment of our “Expert Voices” series, Multiple Sclerosis News Today asked Kassandra Munger to answer some of your questions about the connection between vitamin D levels and multiple sclerosis (MS). Munger received her bachelor’s in biology from the University of Rochester in 1997, master’s in…

Almost half of multiple sclerosis (MS) patients show reduced bone density (osteopenia) and about 17% have osteoporosis, a progressive disease characterized by weak bones that are prone to fractures, a review study of data covering almost 14,000 patients reported. These findings suggest that people with MS should be monitored…

I’ve been popping vitamin D pills for years — decades, really. I never really understood why, I just knew that many people with multiple sclerosis (MS) are vitamin D-deficient. A recent study has cast some new light on why I should continue. It all seems to comes down to…

COVID-19 Booster May Benefit Patients on Anti-CD20 Therapy After multiple reports of how Gilenya and anti-CD20 MS medications reduce the efficacy of the mRNA COVID-19 vaccines, here’s more evidence that a booster shot may improve that protection. The researchers report “modestly increased levels” of anti–SARS-CoV-2 antibodies after a third…

Vitamin D can influence the immune system’s tolerance to certain proteins by changing how DNA is packaged in specific immune cells called dendritic cells, according to a new study. Its findings could have implications for treating diseases like multiple sclerosis (MS) that are characterized by the immune system attacking…

In this installment of our “Expert Voices” series, Multiple Sclerosis News Today asked Allen C. Bowling, MD, PhD, to answer some of your questions related to complementary and alternative medicine (CAM) for people with multiple sclerosis (MS). Bowling is an internationally recognized neurologist and integrative medicine pioneer with…

I’m back in Florida for the next several months, having left cloudy, windy, chilly Maryland for the Gulf Coast. It’s been sunny and in the low 80s for the past few days, and my multiple sclerosis (MS) is feeling just fine. A lot of people with MS avoid the heat,…

Bostick, who has MS, works in private practice in Greensboro, North Carolina, where she helps…

Children and young adults who spend more time outdoors in the sunshine are less likely to develop multiple sclerosis (MS), according to a new study, which suggests that sunshine might help to protect against the disease. “Advising regular time in the sun of at least 30 minutes daily especially…

Vitamin D Deficiency Linked to Early Cognitive Issues in Study I’ve taken a vitamin D supplement for many years because numerous studies have shown a correlation between low vitamin D levels and MS. My levels have been normal for years, and I assume the supplement has helped. Even so,…

Low vitamin D levels in the bloodstream are associated with slower information processing speeds in people with early-stage multiple sclerosis (MS), a study suggests. “Our data support the hypothesis that vitamin D is involved in cognition in MS,” its researchers concluded. The study, “Serum Vitamin D as…

There is no link between serum vitamin D levels and the age at which an individual develops the first symptoms of multiple sclerosis (MS), a new observational study suggests. However, a link was found between cerebrospinal fluid antibody levels, serum vitamin D levels, and the age at first MS…

Can I survive without dessert? Can I live without ice cream, chocolate, and fruit pies, or with only a small amount of beef when I want a burger? The other day, my wife decided to start the ketogenic diet to try to lose some weight. I’m a skinny guy, so…

Lower blood levels of vitamin D binding protein, known as VDBP, were observed in newly diagnosed multiple sclerosis (MS) patients in a new study — findings that suggest the protein could potentially act as a biomarker for the neurodegenerative disease. “The…

Vitamin D, but not paricalcitol (a vitamin D analog), can be used as a preventive measure to control the severity of multiple sclerosis (MS), according to a new study of mice.
