The allegations, "high" and "Source":



To be aware that to mention a vitamin or mineral on the label of a product requires that it covers at least 15% RDA * (recommended daily intake) per 100g of product.

Then, depending on the percentage using one or other of the terms "rich" or "source".

A good "source of ..." covers at least 15% RDA of a certain vitamin or a mineral.

Ex: figs are a source of calcium for 100g figs cover 20% RDA of calcium.



A product "rich in ..." should cover at least 30% RDA of a certain vitamin or a mineral.

Ex: almonds are rich in magnesium as 100g almonds covering 83% RDA of magnesium.
