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.
Named for where it actually works.
Encelar is built from en‑ — within — and cell. Inside the cell is where NAD⁺ is made, spent and replenished, and where a precursor either does its job or doesn't.
That's the whole point of the name. Not a claim about how you'll feel, but a statement about where the work happens. Every batch dosed the same, every ingredient disclosed, every claim measured rather than asserted — because what happens inside the cell isn't something you can feel your way to. You have to measure it.
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."
