Cold-fX

Cold-fX is a branded natural health product marketed as a cold and flu remedy. Its primary active ingredient is a proprietary extract of North American ginseng (Panax quinquefolius) called CQ-101. The product is manufactured by Valeo Pharma, having previously been produced by Afexa Life Sciences Inc. (formerly CV Technologies Inc.).

The claims made regarding Cold-fX center on its ability to reduce the frequency, severity, and duration of cold and flu symptoms, as well as boost the immune system. These claims have been supported by some clinical trials, although the methodology and interpretations of these studies have been subject to scrutiny.

The active compound, CQ-101, undergoes a specific chemical extraction process to purportedly optimize its efficacy. Dosage recommendations vary depending on whether the product is being used preventatively or to treat existing symptoms.

Regulatory bodies, such as Health Canada and the FDA in the United States, oversee the sale and marketing of Cold-fX. While the product is generally considered safe when taken as directed, potential side effects and interactions with other medications should be discussed with a healthcare professional. Consumers should also be aware of the distinction between Cold-fX and other ginseng products, as the specific extract CQ-101 is purported to be unique to the Cold-fX brand. The company and product have experienced controversy regarding marketing practices and the validity of some of the research supporting its claims.
