Mechanism of action

1

L-Ergothioneine antioxidant superiority

MitoPrime (L-ergothioneine) provides antioxidant power exceeding glutathione, vitamin C, and CoQ10. OCTN1 transporter-mediated mitochondrial and immune cell accumulation. Mechanism shared with MitoGreens and MitoReds — the ergothioneine-amplified approach across NNB's superfood line.

2

29-botanical multi-pathway antioxidant

29 superfood botanicals provide multiple polyphenol classes — flavonoids, anthocyanins, proanthocyanidins, phenolic acids. Each polyphenol targets different reactive oxygen species and tissue compartments. Multi-pathway approach broader than single-compound interventions.

3

Mitochondrial function support

MitoGreens-derived formulation specifically targets mitochondrial function — distinguishing from generic greens products. Ergothioneine accumulation in mitochondria plus quercetin AMPK/PGC-1α activation drive mitochondrial protection and biogenesis.

4

Immune cell ergothioneine accumulation

Ergothioneine accumulates in immune cells (neutrophils, monocytes, lymphocytes) via OCTN1 transporter. The high concentrations support immune function via cellular protection during immune activity. Mechanism explains the immune support applications.

5

Phytonutrient-mediated cellular protection

Phytonutrients from 29 botanicals provide cellular protection via multiple mechanisms — direct antioxidant activity, NF-κB modulation, Nrf2 pathway activation, and other signaling effects. Plant-based defense compounds with conserved biological activity across species.
