What Is Quercetin?

Quercetin is a naturally occurring flavonol, a type of plant flavonoid. It is found in foods such as onions and apples.
Laboratory studies examine its effects on oxidative stress responses and signalling pathways such as NF-κB and MAPK. These systems help regulate how cells respond to stress and inflammatory signals.
These research areas explain the interest in quercetin within healthy ageing nutrition and inform its selection for NovaStemix®.
Natural Origins & Ingredient Form

Quercetin occurs naturally in foods such as onions and apples. In these foods, it is often present as glycosides, meaning it is linked to a sugar molecule.
NovaStemix® uses a liposomal quercetin preparation. We consider the ingredient’s form, specification and daily amount within the complete 12-ingredient formula.

Formulation Context
Cell studies examine quercetin’s effects on NF-κB and MAPK signalling, alongside oxidative stress and inflammatory mediators. These findings provide mechanistic context for its study in healthy ageing.
Human studies have examined absorption and selected markers of oxidative stress and inflammation. Results vary across studies, so the population, preparation, dose and outcomes measured matter when interpreting findings.
These findings inform quercetin’s selection for NovaStemix®. Its role is considered alongside resveratrol, curcumin and other ingredients within a formula designed around cellular maintenance and protection.
Why It Is Included in NovaStemix®
Cell studies of quercetin investigate NF-κB and MAPK signalling, which help regulate stress and inflammatory responses. These findings provide a mechanistic basis for its inclusion in NovaStemix®.
NR is an NAD⁺ precursor, while coenzyme Q10 participates in mitochondrial electron transport. We consider these roles alongside quercetin’s research profile when designing the complete formula.
NovaStemix® uses a liposomal quercetin preparation. The recommended daily portion of four capsules provides 250 mg of quercetin.
