Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this project is to study the effect of dietary supplementation with a natural health product (NHP) with a focus on its effects on its levels in breast milk.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The effect of oral cysteine on its levels in breast milk and plasma will be measured in breast feeding mothers.

The investigators will not be studying tryptophan and tyrosine in this study. The title is an overview title left over from other past studies (but the investigators are only assessing cysteine at this time).
