APC Restore is a comprehensive herbal–nutrient formula designed to restore healthy antigen-presenting cell (APC) function, support immune regulation, and improve cellular energy metabolism in individuals recovering from Lingering Pathogenic Illness (LPI). It combines mitochondrial cofactors such as malic acid, alpha-ketoglutarate, magnesium L-aspartate, and inosine to offset metabolic suppression from the itaconate shunt, improving ATP production and reducing post-exertional malaise. Lumbrokinase provides fibrinolytic support to address microvascular impairment, while taurine and berberine modulate inflammation, oxidative stress, and metabolic signaling. The blend also features targeted Chinese herbs - including Ling Zhi, Wu Wei Zi, Bai Zhu, Fu Ling, Yuan Zhi, Huang Qi, and Shan Zha - to tonify Qi, calm the spirit, improve digestive resilience, and enhance immune surveillance. This multi-modal approach addresses both the root and branch of immune dysfunction, making it a core therapeutic option for patients with complex chronic illness, especially those experiencing fatigue, brain fog, poor stress tolerance, and lingering inflammation. For maximum benefit, combine APC Restore with a Lingering Pathogenic Illness formula that suits your symptoms.
