Can I mix brands of dietary supplements?
USANA’s CellSentials and Optimizers are formulated in a manner that allows consumers to use them in combination. When formulating these products, both safety and efficacy were the primary focus. Even when considering typical dietary intakes, the amounts of vitamins and minerals in USANA supplements do not come close to harmful levels when taken as directed.
With that in mind, it is not possible to guarantee that adding additional dietary supplements to a USANA regimen will be safe or efficacious. If an individual seeks greater amounts of a particular nutrient than can be obtained through the recommended use of USANA products, we recommend consulting with a physician, pharmacist, or other health care professional for further advice.
