We have over 500,000 branded foods in our database. You can easily search for a specific branded food or product such as whey protein by selecting the "Branded Foods" database from the list of food databases on the food search page.
By default, the "All Foods (Exc. Brands)" database is selected which searches all our food databases except the branded foods database. So in order to search for branded foods, you need to change this and select the Branded Foods database instead.
