Vitamin D and omega-3 fatty acids have been shown to boost the immune system. Using the data you provided for the GrassrootsHealth study, we assessed the combined effect of vitamin D and omega-3 nutrient status on the occurrence of colds.

We found that the percent of participants who experienced a cold in the prior 6 months was lowest for those with both a higher vitamin D and Omega-3 status (vitamin D levels at or above 40 and Omega-3 Index at or above 6%) compared to those with just a higher vitamin D status, just a higher Omega-3 status, or a lower status for both. Specifically, the occurrence of colds was 28% lower among participants with higher vitamin D and omega-3 status compared to participants with lower vitamin D and omega-3 status.

This suggests that improving both vitamin D and omega-3 status could provide greater risk reduction for colds than either nutrient alone.

Are you getting enough vitamin D and omega-3s?

To know if you are getting enough of these nutrients, make sure you know your Omega-3 Index, and test your level of vitamin D! Testing these levels and taking daily steps to keep your Omega-3 Index at a target of at least 8%, and your vitamin D at a target level of 40-60 ng/ml (100-150 nmol/L), is important for all stages of health.
