Pranin’s products are made from only whole foods, and are regulated as food products. This means that the nutrition facts table legally must contain % Daily Values corresponding to standard Canadian Recommended Daily Intakes (RDIs), which can be used to calculate the unit amounts.
For example, the Canadian RDI for Iron is 14mg. The PureFood Iron provides 150% of that amount, which is equal to roughly 21mg of natural, whole food iron per 1g serving.
