Immunocal Sport — Full Review
Immunocal Sport is the performance-focused member of the Immunocal family — the same world-class glutathione precursor technology at its core, but engineered specifically for athletes, high performers, and anyone who pushes their body hard. Where standard Immunocal focuses on immune and antioxidant support and Platinum addresses aging and inflammation, Sport addresses the specific physiological demands of intense training: oxidative stress, muscle recovery, oxygen delivery, and energy output.
Training creates oxidative stress. Intense workouts drain glutathione — your body's key recovery molecule. Caffeine and creatine can help push performance, but they don't support cellular repair. That gap is exactly what Immunocal Sport was designed to fill. The addition of Tart Cherry, Citrulline, Beetroot, and BCAAs on top of the proven Bonded Cysteine™ foundation creates a genuinely different product from any other sports supplement on the market.
Trusted by Inter Miami & 100+ Olympic Athletes
Athletes from teams including Inter Miami trust Immunocal Sport to help them recover faster and perform better. The Informed Sport certification — which requires independent testing for all banned substances — makes it safe for competitive athletes at the highest levels of sport worldwide, including Olympic competition.
Immunocal Sport is backed by the same 45+ years of research, 79+ patents, and McGill University pedigree that underpins the entire Immunocal line. What's new is the sport-specific formula that adds three evidence-backed performance ingredients to the glutathione precursor base. The result is a pre/post-workout supplement unlike anything else: one that actually addresses cellular health rather than just stimulating performance at the expense of it.

100% Pure Ingredients — What's Inside
From faster absorption to smarter recovery and improved blood flow, every element of the Immunocal Sport formula is designed to support optimal performance. Here are the three sport-specific additions on top of the Bonded Cysteine™ core:
Bonded Cysteine™
Glutathione Precursor — Core FormulaWith up to 1.6× higher bioavailability than common protein sources like chicken or traditional whey, this undenatured protein delivers Bonded Cysteine in a form your body can efficiently absorb and use to produce glutathione intracellularly — the master antioxidant your recovery depends on.
Tart Cherry
Recovery & Sleep SupportTart Cherry is an excellent source of anthocyanins — powerful antioxidants that help reduce exercise-induced inflammation and muscle soreness. It also contains melatonin, which helps regulate sleep and speed up overnight recovery. Faster recovery means more productive training sessions.
Citrulline & Beetroot
Nitric Oxide Boost — PerformanceThis exclusive citrulline and beetroot blend raises nitric oxide levels in the body, which increases the delivery of oxygen and nutrients to muscles during exercise. Better circulation means better endurance, faster pumps, and improved output throughout your training session.
How Immunocal Sport Powers Performance
Citrulline and beetroot raise nitric oxide, boosting blood flow and oxygen delivery to working muscles for longer, stronger performance.
Tart Cherry reduces post-workout inflammation and soreness, while Bonded Cysteine™ helps restore glutathione depleted by intense exercise.
Training creates massive oxidative stress. Glutathione is your body's first line of defense against it — Immunocal Sport replenishes it at the source.
The melatonin naturally present in Tart Cherry supports sleep quality — and better sleep means better hormonal recovery and performance gains.
Rich in EAAs and BCAAs, Immunocal Sport supplies essential amino acids that support both performance during workouts and repair afterwards.
Unlike caffeine or creatine, Immunocal Sport supports actual cellular repair — addressing the root cause of athletic decline rather than masking it.

The Only Sports Supplement That Rebuilds at the Cellular Level
Immunocal Sport is a genuinely different kind of sports supplement. While most products focus on stimulating performance through caffeine, creatine, or pre-workout blends, Immunocal Sport addresses what actually happens to your body during intense training: glutathione depletion, oxidative stress, inflammation, and cellular damage. The combination of Bonded Cysteine™, Tart Cherry, and Citrulline/Beetroot is both unique and scientifically grounded. For serious athletes who want more than a temporary boost, this is a standout product.
Buy Immunocal Sport →What Verified Buyers Are Saying
I am impressed!! I think this is the smoothest whey protein I've had and the other ingredients are a big bonus. Thankfully it doesn't upset my stomach as some other whey products do.
I'm giving Immunocal Sport 4 stars, but only because the formula deserves it; flavor and price wise, it feels more like a 3. Including the mixing cup is genuinely excellent. The ingredient list is impressive — packed with what seem to be high-quality ingredients. The flavor is a major letdown — medicinal and lingering. If they ever fix the taste, this could be a staple; for now, it's a solid product with a serious flavor flaw.
I love it.
More than one reviewer has flagged the flavor as medicinal. This appears to be a genuine tradeoff of the formula — the active compounds (citrulline, beetroot, tart cherry) have strong natural flavors. Mixing into a smoothie or juice largely masks this. If you're mixing with water alone, manage expectations accordingly.
