Emergen-C® is vitamin C-based fizzy drink mix that is designed to give people an energy boost, improve immunity, and overall health. To use this product, simply add the powder to 4 to 6 ounces (118-177 ml) of water or juice, stir, and drink. The less liquid used to mix the drink, the stronger the flavor. Each of the 20 varieties of this drink is slightly different, but all derive fromthe same original formula. The Alacer Corporation, based in Foothill Ranch, California, produces this drink mix and sells it through health food stores, online retailers, and some supermarkets.
The original formula is the basic building block of the Emergen-C® formulas. Vitamin C, the main ingredient in Emergen-C®, is involved in the body's ability to make collagen. Depending upon the formula, the amount of vitamin C in one serving ranges between 0.02-0.04 ounces (500-1000 milligrams). This is 834-1600% of the United States Department of Agriculture (USDA) recommended daily allowance for this vitamin.
The original Emergen-C® formula also contains B vitamins, which help with metabolism and energy. The amount of B vitamins ranges between 400-500% of the USDA's recommended daily allowance, depending on which formula one uses. The minerals magnesium, calcium, phosphorus, zinc, manganese, chromium, sodium, and potassium round out the core ingredients in the original formula. Quercetin and alpha lipoic acids are flavonoids and are included in the original formula. They are in some, but not in all, of the other formulas.
The six Emergen-C® specialty formulas include Vitamin D and Calcium, Joint Health, Heart Health, MSM, Immune Defense, and an electrolyte formula. These come in mixed berry, tangerine, black cherry, and lemon flavors. The vitamins, minerals, or herbs included in these formulas are thought to promote bone, immune, and heart strength.
In addition, the company makes a multi-vitamin fizzy drink mix formula for children that comes in strawberry banana and orange pineapple flavors. The adult multivitamin formula is available in cherry pomegranate and apricot mango flavors. Both vitamin formulations meet the recommended daily allowance for most vitamins, but contain only a small percentage of each mineral's recommended daily allowance.
Emergen-C® megadoses of vitamin C may cause side effects, including stomach upset, nausea, diarrhea, kidney stones, or inflammation of the stomach. There have been no reported interactions between this product and other over-the-counter or prescription medications, however. Despite this, those taking medication may want to check with their healthcare provider before using Emergen-C® just to be safe.
