Recent research hints that vitamin D might play a crucial role in managing multiple sclerosis (MS). A new study out of France examined 303 adults who recently experienced clinically isolated syndrome (CIS), which is a precursor to MS. Participants received high doses of vitamin D3 every two weeks for two years.
The study revealed that 60.3% of those taking the supplements showed a relapse or new lesions on MRI scans. In contrast, 74.1% of those on a placebo experienced similar symptoms, marking a significant difference. This research, conducted by experts from CHU Nîmes and other French institutions, has been published in JAMA.
Dr. Bruce Bebo from the National MS Society, in talks with Fox News Digital, called it a “well-designed study” and noted its promising findings. He mentioned that past studies using lower doses didn’t show the same reduction in MS activity. The study suggests that high-dose vitamin D might reduce disease activity in early MS stages.
The researchers highlighted that a dose of 100,000 IU every two weeks showed notable results in curbing disease activity in those with CIS or early MS. Bebo points out the general recommendation for adults is between 300 to 4,000 IU daily, with 4,000 IU being the upper limit according to most health authorities.
Despite the promising results, Dr. Bebo warned about the potential risks. The study’s dosage was much higher than typical recommendations, and while no adverse effects were reported, excessive vitamin D can lead to toxicity. This can result in high calcium levels, causing symptoms like nausea, vomiting, and even kidney damage.
Anyone considering vitamin D supplements for MS should consult with a healthcare provider to tailor the best plan for their needs. It’s crucial to weigh the benefits against potential risks, especially given the high dosages involved.
