Quality and testing
Sourced in Japan
We source our key ingredients from Japan, where they are produced to exceptionally high standards in FDA-registered facilities.
Japan was a natural choice for Primeadine®. It has a long-standing dietary tradition rich in spermidine-containing foods, such as natto and mushrooms, alongside a global reputation for excellence in longevity research and food safety.
Our manufacturing partners operate under ISO 22000 food safety standards and are certified by the Japan Institute for Health Food Standards. These frameworks ensure careful oversight at every stage, from raw material sourcing through to final production.
Purity & Potency
Every batch of Primeadine® is independently tested to verify both purity and consistency.
Our raw materials are screened by third-party laboratories for contaminants such as heavy metals, pesticides, and microbiological impurities. We also test to confirm spermidine levels in each formulation:
- Primeadine® Original provides 1 mg of spermidine per daily serving
- Primeadine® GF provides 1.2 mg of spermidine per daily serving
This ensures you receive a consistent, reliable product every time.
High Quality Standards
Primeadine® uses spermidine derived from whole food sources, rather than isolated synthetic forms.
In nature, spermidine exists within a complex food matrix alongside other naturally occurring compounds, including related polyamines. This reflects how it is typically consumed in the diet and studied in human research.
By working with food-derived sources, we aim to preserve this natural context, supporting how the body recognises and utilises nutrients.
