Enzymatic & Endogenous Antioxidants for Dogs | La Petite Labs
Mechanisms, relationships, and cross-links for Enzymatic & Endogenous Antioxidants for Dogs.
Enzymatic & Endogenous Antioxidants in Dogs — Abstract
Dogs rely on innate antioxidant systems such as superoxide dismutase (SOD), catalase, glutathione peroxidase, and endogenous molecules like Glutathione for Dogs and CoQ10 for Dogs to counter oxidative stress. These pathways intersect with Nrf2 Support for Dogs and Mitochondrial Support for Dogs, forming the body’s first line of redox defense. La Petite Labs’ Hollywood Elixir™ is designed to complement these native defenses, ensuring senior dogs maintain vitality and resilience.
- Helps maintain cellular energy output in older dogs.
- Supports calmer skin appearance through balanced oxidative load.
- Assists immune defenses by maintaining redox equilibrium.
- Maintains comfort and longevity in senior dogs under oxidative demand.

Defining Enzymatic & Endogenous Antioxidants
Enzymatic antioxidants are specialized proteins that catalyze neutralization of reactive oxygen species. Endogenous antioxidants like glutathione and CoQ10 are produced internally by the dog’s cells. Together, they form a tightly regulated system that shields DNA, proteins, and membranes from oxidative injury.
These native antioxidants are distinct from dietary antioxidants: they are not “extras” but the very machinery that keeps cells alive under stress. Synonyms commonly used include SOD, GPx, and GSH. Within physiology, this defense network is embedded in mitochondrial respiration, NAD⁺/sirtuin activation, Nrf2 transcriptional control, and nutrient-sensing pathways like AMPK and mTOR.
Mechanism Map of Internal Antioxidant Defenses
Their activity translates to observable signs: sustained playfulness, bright eyes, and resistance to fatigue.
Pathways
- Nrf2/Keap1: Regulates antioxidant enzyme expression (Nrf2 Support for Dogs).
- Sirtuins: Connect NAD⁺ levels to longevity signaling (Sirtuin Activators for Dogs).
- AMPK/mTOR: Energy and nutrient sensing (Nutrient Sensing Pathways in Dogs).
- Mitochondrial ETC: Uses CoQ10 for electron transport.
- Autophagy/SIRT1: Repair and renewal (Autophagy & SIRT1 for Dogs).
Nutrient Interactions
- Glutathione for Dogs: Detoxification, immune tone, DNA protection.
- CoQ10 for Dogs: Heart and mitochondrial resilience.
- Vitamin C for Dogs: Recycles vitamin E, supports collagen.
- Vitamin E for Dogs: Guards cell membranes.
- Zinc for Dogs: Cofactor for antioxidant enzymes.
- Polyphenols for Dogs: Modulate signaling and inflammation.
Species Notes
- Canine heart and liver show high oxidative turnover with aging (Cellular Health for Dogs).
- Brain resilience links to enriched environments and antioxidant tone (Brain Health for Dogs).

Quick Q&A
Are endogenous antioxidants enough on their own? In youth, yes—but with aging, dogs often need nutritional support to maintain balance.
Evidence Snapshot
- Veterinary literature emphasizes SOD, catalase, and GPx as essential for canine redox balance.
- Glutathione levels correlate with immune competence and reduced oxidative burden.
- CoQ10 supplementation improves canine cardiac performance in aged dogs.
