“Get sleep under control and everything else gets easier: energy, food, movement, life.” - Elaine Ellis, Co-Founder, Sentro Labs.

In this episode, CEO Elaine Carroll talks with Elaine Ellis about launching Sentro Labs, an Irish, evidence-led supplement brand focused on sleep, stress, gut and hormonal health. We dig into why transparency (clear dosages, cited studies) and Irish manufacturing matter, how Sentro scaled from one SKU D2C to nationwide stockists, and what TikTok Shop changed about growth.

Highlights:

The origin problem: midlife overload, broken sleep, and building a product that tackles sleep and stress together.
Transparency as strategy: published dosages, cited research, full traceability, Irish-made.
Go-to-market: start D2C, prove demand, then add wholesale; why TikTok Shop became a real revenue engine.
Category insight: the male hormonal health gap and Sentro’s traction there.
Ops discipline: outsource logistics early to protect focus and cash flow.
Founder sustainability: sleep first, strength training, batch cooking-burnout prevention in practice.
What’s next: a weight-management line grounded in blood sugar & appetite control, not hype.

👉 Tune in for practical, evidence-driven tactics to build trust, ship better products, and scale smart.
