(WTVR) – Scientists say you shouldn’t look to vitamin D for relief if you catch a cold.
The vitamin has long been thought to boost your immune system.
However, New Zealand scientists followed 322 adults for more than a year and found those who took it were no less likely to suffer a cold than those who did not.
Earlier studies showed a link between low vitamin D levels and an increased risk of respiratory tract infections. But the connections to colds was not clear.
