Why we started SmithCross
The formulas we wanted under one roof.
We were buying different products from different brands to support the same daily priorities: better health, lasting performance, and a longer, stronger life.
SmithCross is owned and founded by Grant and Lauren Smith to bring those essentials together in one considered line. Every product begins with what we would choose for our own routines, then is held to the quality, transparency, and U.S. manufacturing standards we expect for ourselves.
Clinical perspective
Grant Smith is a specialist in longevity and performance medicine, a fellowship-trained physical therapist, and a former collegiate athlete.

Start with what matters.
Each formula begins with a specific purpose and earns its place through ingredient quality, useful dosing, and a clear reason to take it.

Original SmithCross formulas
Custom, not catalog.
Our growing line is being designed around the supplements we use consistently, not a collection of off-the-shelf products chosen to fill a storefront. We are keeping the formulas private while development and testing are underway.
Future formulas will follow the same rule: fewer ingredients, purposeful doses, and clear timing so every component has a reason to be there.
- Purpose first
- Every formula must solve a clear everyday need.
- Quality within reach
- Spend on ingredients and execution, not unnecessary markup.
- Made here
- Manufactured in the United States to our stated specifications.

The SmithCross standard
Premium belongs in the formula, not the markup.
We direct the investment toward sourcing, purity, effective doses, and verification. The result is a supplement line built to be taken consistently, not admired occasionally.
