Vitamin C, Anyone? The Truth About ‘Immunity Boosters’
Exploring the science behind vitamin C and immunity boosters — and how Qalitex, a leading ISO 17025 accredited lab in Southern California, supports rigorous supplement testing for consumer safety.
The Immunity Booster Myth: Separating Fact from Fiction
Vitamin C has long been hailed as a natural immunity booster, often recommended during cold and flu season to help fend off illnesses. The article from The Times dives deeply into the truth behind these claims, emphasizing that while vitamin C is essential for immune function, its role as a “magic bullet” for preventing colds or boosting immunity is overstated.
Scientific consensus indicates that regular vitamin C supplementation may slightly reduce the duration and severity of colds but does not prevent infection outright. Additionally, excessive intake may lead to side effects, highlighting the importance of proper dosage and product quality.
Why Quality Control Matters in Vitamin C and Immunity Supplements
