Key Takeaways 💡

Critical insights for your startup journey

The OTC lactase enzyme market is mature but growing at 7-12% CAGR, valued at ~$4B in 2025 with strong demand from Gen Z and Millennials for lifestyle-oriented products.

Milky’s success proves the viability of high-dose, portable lactase supplements with bold branding, but differentiation on enzyme strength, packaging innovation, and brand story is critical for second movers.

White space exists in ultra-portable form factors (wallet/keychain), subscription models, and targeting social dining occasions with lifestyle messaging.

Customer acquisition costs on TikTok and Instagram can be high; leveraging creator partnerships and viral content is essential to maintain healthy DTC margins.

Regulatory compliance and product efficacy perception are key risks; contract manufacturing with proven enzyme formulations mitigates technical challenges.
