Synergy

What is happening. Spirulina and NAC both support antioxidant defenses through complementary mechanisms, with spirulina (phycocyanin) scavenging free radicals and NAC raising glutathione.

Mechanism. NAC supplies cysteine to drive endogenous glutathione synthesis, while spirulina's phycocyanin directly scavenges reactive oxygen species and improves glutathione-related enzyme activity, reinforcing the same antioxidant network.

Recommendation. Reasonable to combine for antioxidant and detoxification support at standard doses. Effects are complementary rather than redundant.
