Energy your cells make themselves.

I am Esef Cosic, founder of PureNADH and co-founder of Pharm Scale, the factory that makes it.

If you are here, you probably know the feeling. You do everything right and still hit a wall by mid-afternoon. That feeling is the reason this company exists.

I was not looking for a stimulant. I was looking for the molecule the cell itself uses to make energy. That search leads to the NAD family fast. Most of the market sells NAD+ and NMN: the oxidized form and a precursor, which your cells still have to convert and load with electrons. NADH is the loaded form, the molecule that carries the electrons the cell uses at the first step of making ATP. That is why I chose it.

There was a catch. NADH falls apart in moisture, oxygen, light and stomach acid. We started testing in our own laboratory in August 2024 and saw it ourselves. In mid-2025 an independent laboratory in Croatia confirmed it on our first unprotected batch: much of what we had put in was already gone. That batch never reached a customer. If you have tried NADH before, you had no way of knowing how much was left in the capsule. Neither did we, until we measured.

So we kept going, in our own laboratory at Pharm Scale, almost every working day. A formulation, an analysis, a result, and back again. In December 2025 we reached the formulation we still make today. Counting the stability readings that followed, almost two years of testing, from August 2024 to June 2026.

What finally held is a complex, not a coating. The short version is in the box under this letter. We filed it for patent on 6 August 2026. It is patent-pending, not patented, and we will say so until that changes. It is why a 100 mg capsule was worth making.

We did not grade our own homework. An independent laboratory measured how much NADH stayed in our stabilized formulation every month from March to June 2026. Every reading stayed within 5% of the first. It is the same NADH and the same protection that go into every PureNADH batch. You do not have to take my word for it: the readings are on our Science page.

We sold PureNADH in Europe first: the Netherlands in January 2026, Germany a month later. Then the emails from the United States started and did not stop. So we came, officially, in August 2026: Pure NADH Research LLC, Hamilton, New Jersey. The same factory and the same standards.

One honest thing. What we have measured is what we can measure: that our stabilized NADH is still there months later. What happens after you swallow it we have not measured in a study of our own, and I will not pretend otherwise. This is not a stimulant, and you will not feel anything in twenty minutes. Give it the time the guarantee gives you, and decide for yourself. If PureNADH does not do right by you within 100 days of delivery of your first order, write to me and we refund you. I answer for every word on this page.
