Cold & Flu

Cold and flu season puts genuine stress on the immune system. The rhinovirus alone has over 100 strains, and influenza mutates regularly, which is why so many people find themselves symptomatic despite their best efforts.

Several nutrients work through well-understood pathways to support the body during this time. Zinc at doses of 75mg or more may shorten cold duration by interfering with rhinoviral replication, particularly when taken within the first 24 hours of symptoms. Elderberry flavonoids appear to block viral surface proteins from attaching to host cells. Vitamin C supports neutrophil and lymphocyte function, two key players in the early immune response.

Clinical research into echinacea suggests it may reduce the severity and length of upper respiratory symptoms when taken at the onset. N-acetyl cysteine (NAC) thins mucus by breaking apart disulfide bonds in mucus glycoproteins, making it a practical option for congestion. Taking several of these actives together tends to cover more ground than relying on a single ingredient.

Frequent travellers, parents of school-age children, and anyone working in high-contact environments often reach for cold & flu support heading into winter. People who find themselves getting sick repeatedly or struggling to recover quickly are also common users.
