Immunocal Sport and Booster Energy Hibiscus Pack

Immunocal Sport and Booster Energy Hibiscus Pack — The Complete Athletic Performance Bundle

For athletes and active individuals, performance comes down to two things: what you build and what you protect. Building means having the protein, amino acids, and energy systems needed to train hard, recover fast, and adapt effectively. Protecting means shielding muscle cells from the oxidative damage that intense exercise generates — the free radical load that, left unaddressed, impairs recovery, slows adaptation, and accelerates the cellular aging that eventually limits what your body can do.

The Immunocal Sport and Booster Energy Hibiscus Pack brings both dimensions together in a single athlete-focused bundle. Immunocal Sport® delivers the patented glutathione precursor system specifically formulated for athletic performance — with Bonded Cysteine™ to raise intracellular glutathione for cellular protection, L-Citrulline for blood flow and muscle endurance, Beet Extract for nitric oxide support, and Tart Cherry Extract for post-exercise recovery. Immunocal Booster Energy Performance Hibiscus adds the clean pre-workout energy layer — natural caffeine from three sources for sustained alertness and focus, the Nrf2 Catalyst for antioxidant gene activation, and the bright hibiscus flavor that makes it genuinely enjoyable before every training session. Together these two products address every physiological demand of athletic performance from the cellular protection level up.

What Is Included in the Immunocal Sport and Booster Energy Hibiscus Pack

Immunocal Sport® — The Athlete's Glutathione Precursor

Immunocal Sport® is the Informed Sport certified version of Immunocal® — independently tested for banned substances and cleared for use by competitive athletes at every level — enhanced with three targeted performance ingredients that take the foundational glutathione precursor system beyond what standard Immunocal delivers.

Bonded Cysteine™ and the Glutathione Foundation: The core of Immunocal Sport® is the same patented Bonded Cysteine™ technology that makes Immunocal® the world's most clinically validated glutathione precursor. Undenatured whey protein isolate delivers cysteine in its bonded form — the only form that survives digestion and reaches cells intact for glutathione synthesis. Glutathione is the primary intracellular antioxidant that neutralizes the reactive oxygen species that intense exercise generates at the mitochondrial level — protecting muscle cells, supporting immune function during high training loads, and enabling the cellular repair processes that make recovery and adaptation possible. No supplement that simply adds glutathione as a supplement achieves this — orally consumed glutathione is broken down before reaching cells. Only a cysteine precursor that enters cells intact can raise intracellular glutathione where exercise-generated oxidative stress actually occurs.

L-Citrulline — Muscle Blood Flow and Endurance: L-Citrulline is one of the most well-validated ergogenic compounds in sports nutrition. Converted to arginine in the kidneys, L-Citrulline elevates nitric oxide production more effectively than arginine supplementation directly — supporting the vasodilation that delivers oxygen and nutrients to working muscles during exercise and accelerates metabolite clearance during recovery. Research consistently shows that L-Citrulline supplementation improves exercise capacity, delays fatigue onset, and reduces post-exercise muscle soreness — directly addressing the physical performance dimensions that every athlete works to optimize.

Beet Extract — Dietary Nitrate for Oxygen Efficiency: Beet Extract provides a concentrated source of dietary nitrates that are converted to nitric oxide through a complementary pathway to L-Citrulline — amplifying the vasodilatory and oxygen utilization benefits without redundancy. The combination of L-Citrulline and Beet Extract in Immunocal Sport® creates layered nitric oxide support from two distinct biochemical pathways — improving the oxygen efficiency, blood flow, and muscle endurance that separate good athletic performance from great athletic performance.

Tart Cherry Extract — Post-Exercise Recovery and Anti-Inflammation: Tart Cherry Extract is one of the most evidence-supported natural recovery compounds in sports nutrition research — delivering anthocyanin antioxidants and anti-inflammatory compounds that specifically target exercise-induced muscle damage, delayed onset muscle soreness, and the inflammatory signaling that impairs recovery between training sessions. Competitive athletes, weekend warriors, and anyone training regularly will recognize the value of a genuine recovery compound built into their daily glutathione precursor — addressing both the protective antioxidant layer and the active recovery layer in a single serving.

Immunocal Sport® is fat-free, sugar-free, and lactose-intolerant friendly. 30 pouches per box.

Immunocal Booster Energy Performance Hibiscus — The Nrf2 Energy System, Hibiscus Flavor

The Immunocal Booster Energy Performance Hibiscus is the clean pre-workout and daily energy companion to Immunocal Sport® — delivering the proprietary Nrf2 Catalyst that makes the Booster uniquely valuable in the Immunotec system, alongside natural energy from three caffeine sources and the light, refreshing hibiscus flavor that makes daily pre-training use genuinely enjoyable.

The Nrf2 Catalyst — Amplifying the Glutathione System: The most important function of the Immunocal Booster Energy Performance Hibiscus for athletes using Immunocal Sport® is its Nrf2 activation. Nrf2 — Nuclear factor erythroid 2-related factor 2 — is the master regulator of the body's endogenous antioxidant gene expression. When activated, it switches on the genes that produce glutathione, glutathione peroxidase, superoxide dismutase, catalase, and a broad range of other protective antioxidant and detoxification enzymes. Sulforaphane from broccoli seed extract — the most potent known Nrf2 activator — provides this gene-level activation, while selenium supports the glutathione peroxidase that uses the glutathione Immunocal Sport® helps produce. The Booster Energy Performance does not raise glutathione directly — but it dramatically amplifies the effectiveness of the glutathione that Immunocal Sport® enables your cells to make.

Natural Caffeine From Three Sources: Green tea leaf extract, green coffee bean extract, and guarana seed extract deliver approximately the equivalent energy support as a moderate coffee serving — with natural, plant-sourced caffeine that provides onset within 15 minutes and duration of up to 6 hours without the hard crash. Vitamins C and B12 support mental focus and reduce tiredness and fatigue. The result is the kind of clean pre-workout energy that supports both training performance and the alertness needed for demanding days outside the gym.

Hibiscus Flavor — Refreshing Pre-Training Experience: The hibiscus flavor of this Booster variant brings a bright, floral, slightly tart profile that is particularly refreshing when mixed cold before training. It is light and clean rather than sweet — making it practical as a pre-workout without the heavy sweetness that some fruit-flavored supplements carry. Sugar-free, gluten-free, vegan.

30 stick packs per box.

Why Immunocal Sport® and the Booster Energy Performance Work Best Together

This combination was not assembled arbitrarily — these two products are purpose-built complements in the Immunotec ecosystem.

Immunocal Sport® raises intracellular glutathione, providing the cellular antioxidant foundation that protects muscle cells during training and enables recovery afterward. The Booster Energy Performance Hibiscus activates Nrf2, switching on the gene expression that makes the glutathione produced through Immunocal Sport® maximally effective through the selenoprotein enzyme glutathione peroxidase. One product provides the raw material — the other activates the system that deploys it.

The energy and focus benefits of the Booster also address a practical need that glutathione precursors alone do not — they keep training motivation, intensity, and focus elevated on the days when showing up and pushing hard is what separates athletes who progress from athletes who plateau. Clean energy before training, cellular protection during training, and accelerated recovery after training: the complete athletic performance cycle covered in two daily products.

Who the Immunocal Sport and Booster Energy Hibiscus Pack Is For

This bundle is designed for physically active adults who train regularly and want both performance and longevity from their supplement routine — athletes who recognize that managing oxidative stress is as important as managing training load. It is equally appropriate for competitive athletes who need Informed Sport certification, recreational gym-goers who want to train consistently without injury or excessive soreness, and active adults over 40 who are prioritizing both performance maintenance and cellular health as training demands interact with the natural decline in antioxidant capacity that comes with age.

How to Use the Immunocal Sport and Booster Energy Hibiscus Pack

Immunocal Sport®: Mix one pouch with 6 oz of cold water or milk in a shaker cup. Take once daily, preferably in the morning on a light stomach for optimal cysteine absorption. Do not blend at high speed or heat — the undenatured protein requires gentle mixing to preserve bioactivity.

Immunocal Booster Energy Performance Hibiscus: Mix one stick pack with 6 oz of cold water 15 to 30 minutes before training, or whenever sustained energy and focus are needed. Take once daily. Avoid after 3pm if sensitive to caffeine. Take together with or shortly after Immunocal Sport® for the most complete combined glutathione-Nrf2 system activation.
