FAQ
What is SIGNAL?
SIGNAL is a supplement brand for high screen-time professionals — founders, developers, remote workers, and creators. We make science-backed, low-hype products designed to support daily clarity, calm, and steady performance.
Are these products safe?
All SIGNAL products use well-established ingredients with a strong safety profile. We follow conservative claim guidelines and include FDA disclaimers on every product page. Always consult a physician if you have a medical condition, are pregnant, or are under 18.
What's the difference between strips and capsules?
Strips dissolve on the tongue in seconds — no water, no swallowing. They're designed for convenience and speed. Capsules are better for larger ingredient doses and are taken as part of a morning or evening routine.
How long until I notice a difference?
Most adaptogenic and nootropic ingredients work cumulatively. Give it 2–4 weeks of consistent daily use before evaluating. Daily habits matter more than single doses.
Do you ship internationally?
Currently US-only. International availability may be added in future.
Who fulfills the orders?
Products are fulfilled on demand — no warehouse inventory, no expiry risk.
What does "bundle" mean? Do the products ship together?
Bundles are convenience groupings at a discounted price. Each item in a bundle ships and is fulfilled separately — you will receive multiple packages, one per product.
