Vitamin D and MS

February 4, 2026 | Pippa Vincent-Cooke

A long term study of women in Norway has shown that a higher intake of vitamin D from food and supplements was linked to a lower risk of developing MS.

Researchers found that women with higher vitamin D intake had a 42 percent lower risk of developing MS compared with those who consumed less. The results were similar whether vitamin D came from food or supplements, suggesting vitamin D itself may play a role rather than sunlight alone. Vitamin D is well known for supporting bone health, but it also helps regulate the immune system and supports brain and muscle health.

The researchers say the findings support the idea that vitamin D may help influence MS risk, particularly in areas with limited sunlight. While this research does not prove cause and effect, it adds to growing evidence that vitamin D may play a role in MS risk. Anyone considering supplements should speak with a healthcare professional to find what feels right for them.
