Beeswax is edible and passes through the digestive system largely unchanged.
Beeswax is approved as a food additive (E901 in the EU) and is used as a glazing agent on confectionery and fruit. It is composed of long-chain esters and hydrocarbons that human digestive enzymes do not appreciably break down, so it contributes negligible energy or nutrients and is excreted essentially intact.
What this does not claim: This does not claim beeswax has nutritional value, and it does not claim any quantity is safe — very large amounts of indigestible material can cause obstruction, though not at any realistic level of consumption.
