Abstract
L-5-hydroxytryptophan-based supplements can be obtained either from the natural source seeds of Griffonia simplicifolia or it can be produced (bio)synthetically, the latter resulting in a higher profit. Natural products must therefore be protected against economical frauds. Stable isotope ratio analysis can serve this purpose, discriminating effectively between natural and (bio)synthetic products
