Perceived insufficient milk production (PIM) adversely affects breastfeeding duration. Women sometimes use galactagogues with the intent to increase breast milk production and support lactation. yeast-based supplement (SCYS) is an inactive form of yeast (SCY) either obtained from the fermentation process or grown on molasses. Anecdotal evidence suggests SCYS is a galactagogue. SCYS is promoted on the internet as a galactagogue in various forms and doses. Dietary supplementation with SCYS during gestation and lactation significantly increases milk yield in ruminants. No human study has evaluated efficacy of SCYS as a galactagogue. SCYS is rich in B vitamins, beta-glucan, mannan oligosaccharides and bioavailable chromium; these may impact breast milk production or composition, thus may alleviate PIM. The safety of taking SCYS during lactation is not well studied. Studies have reported contamination of SCYS with ochratoxin A (OTA) as well as minor side effects from SCYS. Studies are needed to evaluate the efficacy of SCYS on breast milk production and composition and to assess the safety of taking SCYS during lactation in humans.
认为母乳不足（PIM）会对母乳喂养时间产生不利影响。女性有时会使用催乳剂来增加母乳产量并支持哺乳。酵母基补充剂（SCYS）是酵母（SCY）的一种无活性形式，要么是通过发酵过程获得的，要么是在糖蜜上生长的。一些传闻证据表明 SCYS 是一种催乳剂。SCYS 以各种形式和剂量在互联网上被宣传为催乳剂。在妊娠和哺乳期补充 SCYS 可显著增加反刍动物的牛奶产量。目前没有研究评估 SCYS 作为催乳剂的功效。SCYS 富含 B 族维生素、β-葡聚糖、甘露寡糖和生物可利用的铬；这些可能会影响母乳的产量或成分，从而可能缓解 PIM。关于在哺乳期服用 SCYS 的安全性尚未得到充分研究。研究报告称 SCYS 受到赭曲霉毒素 A（OTA）的污染，以及 SCYS 带来的轻微副作用。需要进行研究来评估 SCYS 对母乳产量和成分的影响，并评估人类在哺乳期服用 SCYS 的安全性。
