We started Sigma because the supplement aisle has a trust problem.
Walk down any supplement aisle and you'll find bold promises, beautiful labels, and almost no way to verify a word of it.
"Proprietary blends" that hide how little active ingredient is actually inside. Doses a fraction of what the research used. Purity claims no one ever checks. The whole category runs on hope — that the powder in the capsule is what the label says.
We thought longevity — of all things — deserved better than hope.
In statistics, sigma measures consistency.
The σ symbol represents standard deviation — how much variation there is from the mean. Low sigma means tight, reliable, predictable.
That's not an accident. It's the entire promise. Every batch dosed the same. Every claim measured, not asserted. Every jar the same as the last. In a category built on variance, we named ourselves after its opposite.
Four principles. No exceptions.
Disclose everything
Every ingredient, every dose, printed in full. No proprietary blends — ever. If it's in the capsule, it's on the label at the exact amount.
Dose to the research
We formulate to the levels used in published studies, not to whatever protects a margin. An underdosed active is just an expensive placebo.
Test every batch
Independent, third-party testing for purity, potency, and contaminants — on every production run. If a batch fails, it never ships. The report is public.
Claim only what's proven
We tell you what the science establishes, what's emerging, and what isn't known. We are not in the business of selling immortality.
What we are, and aren't.
- A brand that promises to reverse aging
- Hiding doses behind a "blend"
- Asking you to just trust the label
- Making disease or cure claims
- A precision-dosed NAD⁺ precursor, fully disclosed
- Third-party tested, every single batch
- Honest about what the evidence does and doesn't show
- Built for people who read the fine print
"We built the company we wished existed when we started reading supplement labels ourselves — one that treats you like someone smart enough to want proof, not just promises."
