Can You Take Glycylglycine with Threonine?

Research shows that taking Glycylglycine with Threonine does not cause any significant interactions. A study on human jejunum found that Glycylglycine did not affect the absorption of amino acids from a mixture simulating casein. This suggests that combining Glycylglycine and Threonine is unlikely to cause any adverse effects. No mechanism of interaction was identified between Glycylglycine and Threonine. The absorption of amino acids, including Threonine, from a mixture or a partial enzymic hydrolysate of casein containing small peptides like Glycylglycine appears to be unaffected.
