Can You Take Cysteine with Sarcosine?

There is no evidence that taking cysteine and sarcosine together causes any adverse effects or interactions. They can be used simultaneously without concern. No special monitoring is required. No mechanism of interaction was identified between cysteine and sarcosine. They appear to work independently without influencing each other's biochemical pathways. One technical term to note is that sarcosine oxidase, an enzyme involved in sarcosine metabolism, does not seem to be directly affected by cysteine.
