Immune Support

Comprehensive immune + antioxidant support This is the primary immune-support formula in the protocol. Immune Active combines vitamin C, zinc, N-acetylcysteine (NAC), quercetin, and green-tea polyphenols/EGCG, providing nutritional and antioxidant support for healthy immune function and glutathione production. Because this formula already contains zinc, vitamin C, NAC, and quercetin, additional supplementation with these nutrients generally does not need to be included in this foundational protocol unless individually indicated.

Vitamin D + immune function Vitamin D plays an important role in normal immune function and immune signaling. Individual needs can vary considerably depending on current vitamin D status, sun exposure, dietary intake, season, and existing supplementation. For longer-term or higher-dose supplementation, vitamin D is best individualized using serum 25-hydroxyvitamin D [25(OH)D] levels.

Gut + immune support The gastrointestinal tract and immune system are closely interconnected. Probiotic IMM provides 5 billion CFU per capsule from five probiotic strains, including Bifidobacterium longum BB536, B. lactis, Lactobacillus acidophilus, L. plantarum, and L. casei. It is specifically formulated to support gastrointestinal microbial balance and healthy immune function.

Additional immune-resilience support A beta-glucan/larch arabinogalactan formula provides polysaccharides used to support normal immune-system activity and complements the nutritional, antioxidant, vitamin D, and microbiome support provided by the rest of the protocol.
