VitaGuard

Today, most supplement brands only tell you how good their products are. They rarely warn you about the risks of taking multiple supplements at the same time—whether from the same brand or different ones—or the possibility of exceeding safe intake levels. They also don’t tell you whether the dosage is actually effective or just a placebo-level amount. This app brings together health intake guidelines from China, the United States, Europe, Australia, and the World Health Organization, helping you make smarter decisions when using nutritional supplements.
