Vitamin C works on the body in several ways, including the healthy formation of bones, skin and blood vessels. While not a cure for the common cold as many think, it has been shown in scientific studies to reduce the severity of cold symptoms in children and adults. Vitamin C is water-soluble, meaning your body does not store it for later use, which is why daily supplementation is often recommended.

Got sick? Get some Vitamin C, or so the common thinking goes. But not all Vitamin C is created equal. Some products have been developed more directly toward lessening cold symptoms, and they often include blends of other vitamins, minerals and natural compounds known to help allergies, flu and the seasonal cold. Zinc, echinacea and b-complex vitamins are common cold-busting additions.

Vitamin C is most often sold in capsule or pill form. There are also vitamin gummies widely available—think gummy bears, but good for you. The downside of pills is not everyone can swallow them, especially when sick. Gummies, while often tasty, often have added sugar to make them more palatable. Vitamin C in powdered form is perhaps the most direct and easy-to-consume method of delivery. Without flavoring, Vitamin C has a refreshingly tart, acidic taste that many liken to citrus.

One often overlooked ingredient added to Vitamin C to help fight cold symptoms is rose hip. Rose rib is the rounded portion of the rose bud, just under the petals, which holds the seeds. Dried, the hip and seeds are a natural source of Vitamin C. Unfortunately, most of the Vitamin C content of rose hip is degraded in the drying and manufacturing process, but some studies show it still helps reduce pain and join stiffness associated with osteoarthritis. This is why it’s often added to lab-made Vitamin C found in most common cold supplements.
