B complex with Vitamin C contains a full spectrum of B vitamins. These nutrients play a critical role in the body systems responsible for energy production, which helps to combat stress. The B vitamins are important for helping to reduce anxiety, depression, irritability, and nervousness. Vitamin C provides for better immune system function under stress so individuals are better able to combat illness. The B vitamins and vitamin C are often referred to as the “stress vitamins” because they are depleted by stress. They are water-soluble and are not stored in the body and thus require a daily intake. Most of the B vitamins, along with many other nutrients, are also removed when foods are highly refined or during the processing and cooking of foods. Products that have gone through an enrichment process have only a few of these essential nutrients replaced. Therefore, individuals may require additional supplementation for these very important vitamins.
