We use a few online calculators, and have mainly been using VeryWellFit.com‘s for most of the recipes. The nutritional information may vary from calculator to calculator since they can use different brand names for different items, and therefore might have different numbers. Add in the human factor, the fact that premade items often change recipes, and new science methods, and you can see how these numbers can vary greatly at times. So please use our nutritional information as a guide line not as a set guarantee. Feel free to input the recipe into your calculator that you trust.
