It helps you take your stack every day. Varsity Stack is free. CHECK A PRODUCT • Scan a barcode, or take a photo of the front label. • See if a certification program lists the product. A match names the program. • No match means the product is not on the lists we check. It says nothing else about the product. • Read the ingredients on the label.

Each one shows why it was chosen for you. • Search certified products by name. • Add a product from a link, or type it in. • Share a product page from another app to add it to your stack.
