Sustainable menstrual products like menstrual cups, reusable pads, discs, and period underwear benefit the environment, economy, and health. Their presence in advertisements is far less than traditional disposable menstrual products. This study attempts to explore the various reasons that cause the limited promotion for sustainable menstrual products. Qualitatively, this research is based on secondary data and studies the negative promotion of sustainable menstrual products caused by menstruation-related stigmas, historical advertisement bans, the disposable product brand monopolies, and the censorship of promotional advertisements as evidenced by market reports and peer-reviewed academic articles. From the thematic analysis, three major structural barriers were identified: censorship of the menstrual cycle, commercial barriers, and digital barriers combined with inadequate consumer awareness. The findings reveal that the invisibility of sustainable menstrual products is driven by interconnected cultural, commercial, and technological factors rather than product quality or consumer demand. The study recommends more inclusive advertising policies, increased public awareness initiatives, and equitable digital marketing opportunities to promote sustainable menstrual health.
