Top 100 sources of cystine

Top 100 sources of cystine

Before I give you the list, let me explain how I came up with it as it is a combination of two factors: relative ratios of amino acids and protein density.  In this list I only look at foods that have at least 26% of their calories from protein and then I rank them according to those with the highest relative amount of the target amino acid.

This page is static, the most accurate and current top cystine sources can be found thru my database.
