Seasonal occurrences of cold and flu are to be expected. Targeting the immune system during this time has the potential to help decrease the frequency, severity, or duration of cold and flu symptoms. Decreasing the risk of developing a cold or flu is possible through prophylactic supplementation, especially among high-risk populations, such as in children, the elderly, or those with compromised immune systems.
In the event a cold or flu does occur, the desired focus of supplementation may shift to decreasing the duration and severity of symptoms. Zinc may be considered in this case; when given during the initial 24 hours of symptom onset, it has been shown to reduce the number of patients with symptoms after one week. (Singh 2015) Vitamin C is another popular remedy to decrease the length of a cold and has the potential to decrease duration by approximately half a day. (Ran 2018)
The ingredients present in the protocol below reflect research findings that demonstrate efficacy when used prophylactically and therapeutically to support physiological immune function in regards to cold and flu.
Vitamin C
Vitamin C
Adults: 1 g daily as an ongoing maintenance dose, (Hemila 2013)(Johnstone 2014)(Ran 2018) or 3 to 4 g daily at the onset of symptoms and for the duration of illness (Hemila 2013)(Ran 2018)
Children: 1 to 2 g daily as an ongoing maintenance dose (Hemila 2013)
Reduces the duration of the common cold by approximately a half-day, (Ran 2018) or by 8% in adults and by 14-18% in children (Hemila 2013)
Reduces time of confinement by approximately six hours and fever duration by approximately a half-day, relieves chest pain and chills by approximately eight hours when given an extra therapeutic dose at the time of onset of cold (Ran 2018)
Improves antimicrobial and natural killer (NK) cell activities, lymphocyte levels, chemotaxis, delayed T cell responses, sympathetic nervous response, and induces anti-reactive oxygen species activity (Ran 2018)
Decreased duration of cold by 59% and increased weekly activity levels by 39.5% when compared to placebo in otherwise healthy adult males (Johnstone 2014).
