Core supplements have the best safety-efficacy profile. When used responsibly, they are the supplements most likely to help and not cause side effects.*

The following is a list of recommended core supplements, some are sold here on the Journey to Health website but this is mainly a helpful information section for you when learning about vitamins and supplement benefits.
What makes garlic a core supplement?
By improving the ability of white blood cells (lymphocytes) to fight invaders and by increasing the production of T cells (T lymphocytes), garlic can enhance the immune system and thus reduce the risk of colds and other infections. Garlic will not, however, reduce the duration of a disease or the severity of the symptoms; it is a preventive supplement.
What makes vitamin C a core supplement?
Vitamin C is unique in that it can be either an antioxidant or a pro-oxidant, depending on physiological context. Vitamin C is researched mostly for its effects on colds. It might help reduce the duration and severity of colds, but only when taken regularly (so before the first symptoms). In people who are physically very active, and thus more likely to get sick, it can also reduce the occurrence of colds
What makes vitamin D a core supplement?
Low levels of vitamin D have been associated with worse immune function and increased rates of acute respiratory infection, possibly due to its role in regulating the immune system as outlined below. For example, it has been well documented that low levels of vitamin D in countries with suboptimal sunlight (about 32-42o N or S of the equator) as well as a genetic predisposition for low vitamin D status are both associated with increased rates of acute 18 respiratory tract infections. This observation has also been seen in the United States, specifically. These data suggest that adequate vitamin D status might be a protective factor against acute respiratory tract infections
