The present invention relates to cell culture media comprising inorganic ester derivatives of tyrosine and/or cysteine. The poor solubility of tyrosine and the often non-sufficient stability of cysteine in cell culture media is overcome by substituting them with an inorganic ester derivative, e.g. with a phosphorylated derivative.
