Top 10 Foods Highest in Leucine

Leucine is an essential, branched-chain amino acid (BCAA), required for the growth and repair of muscle, skin and bone. Leucine is suspected to be the only amino acid that can stimulate muscle growth and help prevent the deterioration of muscle with age.

High leucine foods include chicken, beef, pork, fish (tuna), tofu, canned beans, milk, cheese, squash seeds, and eggs. The reference dietary intake (RDI) for leucine is 39mg per kilogram of body weight, or 17.7mg per pound. A person weighing 70kg (~154 pounds) should consume around 2730mg of leucine per day.

Below is a list of the top 10 foods highest in leucine with the %RDI calculated for someone weighting 70kg (154lbs). For more high leucine foods see the extended list of leucine-rich foods.
