A nutritionist says vitamin C tablets and gummies do not prevent most winter colds, despite being widely used during the cold season. The outlets report that people often take the supplements with the expectation they will ward off infections.
The articles cite research that challenges common marketing claims around vitamin C. While vitamin C is an essential nutrient for immune function, the coverage indicates that evidence does not support strong protection against most colds when taken as tablets or gummies. The reports present the supplements as unlikely to deliver the preventive effect many consumers assume.
Both sources focus on the gap between consumer expectations and scientific findings, emphasizing that vitamin C may not be a reliable strategy for preventing the majority of winter colds. They do not indicate that vitamin C is harmful, but they stress that its effectiveness as a cold-prevention measure is limited.
