The Science Of NAD+

Backed by Research

We follow the science. We verify the science. We uphold the science.

With NMN and NR supplements becoming increasingly popular, it’s more important than ever to separate real, evidence-based research from marketing hype.

We go the extra mile to ensure that every supplement we produce is grounded in peer-reviewed scientific studies, human clinical trials, and expert-reviewed data.

Safety & Quality Assurance

Full Lab Testing Reports Available

We take our supplements. Our family take our supplements. Our friends take our supplements. That’s why our safety standards are so high.

It's so refreshing to find a company as dedicated to their customer's safety as NADBio. I found their support team to be completely open and honest with every question I had. I won't buy my NR supplements from anywhere else now.

Premium Ingredients

Synthetically produced supplements allows for higher purity, greater bioavaliability, and eliminates contaminants found in naturally occuring products.

Derived From Naturally Occurring Compounds

Our supplements are synthetically derived from nautrall occurring compounds found in foods like broccoli, avacados, and soybeans.

This helps eliminate contaminants, provide greater bioavaliability, more scalability and sustainability, and allows for higher purity and consistency.

Bioidentical Forms

Our supplements are bioidentical to the forms found in your body. Meaning they function exactly the same their naturally occurring coutnerparts.

Our supplements are made through fermentation or enzymatic synthesis to ensure purity, stability, and effectiveness.

Higher Bioavaliability

Premium ingredients are safer. Rigeous raw-material testing eliminates contaminants, heavy-metals, and impurities from entering our supplements.

Premium ingredients ensure higher bioavailability, meaning your body absorbs and utilises them more efficiently.

Full Process Testing

We test every stage - from raw material sourcing to the finished product. This ensures that every ingredient meets strict quality and safety standards before it reaches you.

You can be confident that what's marked on the pack is what's contained in the pack. Nothing goes unchecked, guaranteeing a clean and effective supplement.

Strict Process Monitoring

Our manufacturing process is monitored for lab compatibility, ensuring that every batch is certified, free from contaminants, and meets our high-performance standards.

Any labs involved in the production or testing of our supplements are ISO-Certified and conform to the FSA standards.

Transparent Reports

We believe in full transparency. We quality test raw ingredients and every finished batch to enquire it meets our high quality standards.

Want to see your batch test results? Email us your batch number and we'll send you the lab report.

We stand by our quality, and we’re happy to prove it.

Testing & Certification

Every batch of our supplements undergoes rigorous testing to ensure purity, potency, and safety. From raw materials to final production, we guarantee uncompromising quality.

Clinically Researched

Our supplements are forumaled based on the latest human clinical research – ensuring you our dosages are scientifically validated and safe. These include regulatory dosages stipulated by agencies such as the Food Standards Agency (FSA).

Research Backed Dosages

Many brands either underdose or overdose their formulas, limiting their effectiveness. We follow human clinical trials to ensure our dosages are scientifically validated and safe:

Dosage amounts are also backed and regulated by the UK Food Standards Agency.

Advanced Delivery

Standard NMN and NR can break down in the stomach, reducing their effectiveness before reaching your cells.

That's why we use and develop delivery methods such as delayed-release capsules (protecting the supplement from the stomach acid) and high-stability forumals (to prevent degradation and maintain potency).

Scientific Driven Forumlations

Every supplement, ingredient and dosage we use is founded from human clinical trials, and cross verified with multiple studies. The supplement market is flooded with poor-quality, high profit margin products. You deserve supplements that are backed by real science, lab-tested, and clinically researched.
