Core Training Supplements
1. Informed Whey® Protein by Bulk™
Anthony Joshua's supplement foundation starts with Informed Whey®, which he has directly called his "favorite Bulk™ product." The British heavyweight consumes this protein before training sessions or mixed with breakfast, making it central to his daily routine. The formula delivers 24g of protein per serving through a whey isolate–dominant blend, part of Bulk™’s mTOR Whey Complex™ formulation.
Key benefits:
-
Contains 3g of leucine and 3g of glutamine peptides to trigger muscle protein synthesis
-
Informed Sport certification ensures batch testing for banned substances
-
Supports recovery during camps where Joshua trains up to three times daily
-
Fast absorption makes it ideal for pre-training or breakfast consumption
The formulation specifically addresses the breakdown that occurs during intense boxing training. Joshua has explained that "during camp I train" up to three times daily, making protein timing and absorption critical. The Informed Sport certification ensures every batch is tested for banned substances, a non-negotiable requirement for professional athletes competing at championship levels.
For athletes prioritizing strength and performance alongside muscle recovery, high-quality whey protein addresses the dual demands of acute recovery and sustained performance capacity that elite training requires.
2. Aftermath™ Post-Workout Recovery by Bulk™
Immediately after training, Joshua turns to Aftermath™, an all-in-one recovery formula combining protein and carbohydrates. This supplement addresses what Joshua describes as urgent nutritional demands post-workout, when his muscles have been "ripped apart" and damaged through training.
Why the dual approach works:
-
Protein triggers muscle protein synthesis for repair
-
Carbohydrates replenish depleted glycogen stores
-
Insulin response enhances nutrient uptake into muscle cells
-
Timing-specific formula capitalizes on the post-workout recovery window
According to research on post-exercise nutrition, consuming both protein and carbohydrates within the post-workout window optimizes recovery. Joshua has confirmed using "a blend of protein and carbohydrate shakes to help me recover and give me the energy to keep training." As part of Bulk™'s PRO Series with Informed Sport certification, the formula meets the same anti-doping testing standards as his other supplements.
Athletes who train with similar intensity can enhance recovery further by supporting cellular protection. XV1's Glutathione Complex provides liposomal glutathione for superior cellular protection, helping combat oxidative stress from high-volume training.
3. Caffeine and Pre-Workout Supplements
Unlike many athletes who rely on daily stimulants, Joshua takes a strategic approach to caffeine supplementation. Nutritionist Mark Ellison revealed that when the boxer's energy lags, he "might have caffeine" through either coffee or pre-workout supplements to "perk him up."
Strategic caffeine use:
-
Prevents tolerance buildup from daily consumption
-
Maintains effectiveness for peak performance demands
-
Allows natural energy systems to function optimally
-
Informed Sport-certified pre-workouts ensure anti-doping compliance
This measured strategy reflects sophisticated understanding of stimulant usage. Ellison noted that during Joshua's 2018 camp, he hadn't needed caffeine, suggesting that adequate sleep, nutrition, and recovery make constant stimulation unnecessary. When Joshua does use pre-workout supplementation, he prioritizes certified products while "boosting his energy" before working out.
For sustained energy and focus without stimulant dependence, XV1's Green Superfood Powder provides natural energy through B-vitamins and organic greens while filling nutritional gaps.
Performance Optimization and Hydration
4. Electrolyte Drinks and Hydration Supplements
Hydration management becomes critical when training three times daily in the volume Joshua maintains. The boxer incorporates electrolyte supplementation as part of his training protocol, with Ellison noting that when caffeine isn't needed, Joshua opts for electrolyte drinks to maintain mineral balance.
Why electrolytes matter:
-
Replace sodium, potassium, and magnesium lost through sweat
-
Regulate muscle contraction and nerve signaling
-
Maintain fluid balance across multiple training sessions
-
Support performance without unnecessary stimulation
The mineral replacement becomes particularly crucial during high-intensity training when sweat loss depletes electrolytes at rates that water alone cannot restore. These minerals regulate muscle contraction, nerve signaling, and fluid balance—all critical for maintaining performance across multiple daily sessions. The combination of electrolyte drinks with recovery shakes ensures both mineral balance and macronutrient delivery happen in tandem.
While electrolytes address acute hydration needs, comprehensive gut health support enhances nutrient absorption. XV1's Green Superfood Powder includes an advanced probiotic blend with prebiotic fiber and digestive enzymes.
Recovery and Longevity Support
5. CBD Oil for Sleep and Recovery
Joshua has integrated CBD oil into his recovery protocol, particularly around high-stakes fights. As a partner with CBD brand Love Hemp, the boxer has embraced CBD as part of his wellness approach for sleep optimization and recovery support. The timing of his CBD adoption—specifically before critical comeback fights—underscores his confidence in the supplement's recovery benefits.
CBD's proposed benefits:
-
Supports sleep cycle regulation through endocannabinoid system modulation
-
May help manage inflammation response from training stress
-
Supports overall recovery and wellness
-
Increasingly adopted by elite athletes for recovery protocols
While research on CBD in athletic performance continues to develop, many professional athletes have incorporated it during critical training and recovery periods. For athletes seeking comprehensive detox and cellular health support beyond sleep optimization, XV1's Glutathione Complex addresses oxidative stress at the cellular level.
6. Sports Multi AM:PM™ by Bulk™
As part of his Bulk™ supplement lineup, Joshua uses products from the PRO Series including Sports Multi AM:PM™, a split-dose multivitamin formulation. The AM/PM split dosing optimizes absorption by separating nutrients that compete for uptake pathways and timing certain vitamins with the body's natural circadian rhythms.
Split-dosing advantages:
-
Morning dose supports energy metabolism with water-soluble vitamins
-
Evening dose focuses on recovery and cellular repair
-
Prevents nutrient competition for absorption pathways
-
Aligns with circadian rhythms for optimal utilization
The comprehensive vitamin and mineral support becomes essential when training volume reaches 30 hours weekly, as micronutrient demands increase with metabolic rate and physical stress. While whole foods form the foundation of Joshua's nutrition, the multivitamin fills gaps that emerge when caloric needs prioritize macronutrients. The Informed Sport certification maintains anti-doping compliance across his entire supplement stack.
Athletes focused on longevity and vitality can amplify multivitamin support with targeted cellular optimization through comprehensive wellness supplements.
7. Omega-3 (PROM3GA™) and Essential Fatty Acids
Omega-3 supplementation addresses the anti-inflammatory needs of a boxer whose training volume generates significant exercise-induced inflammation. While Joshua hasn't explicitly detailed his omega-3 usage, PROM3GA™ appears alongside other Bulk™ products he endorses.
Omega-3 benefits for athletes:
-
EPA and DHA fatty acids modulate inflammatory pathways
-
Support cardiovascular health and brain function
-
May help prevent exercise-induced muscle damage
-
Critical for managing inflammation from high training loads
According to research published in Sports Science Exchange, omega-3 fatty acids play important roles in reducing inflammation and supporting exercise recovery. For an athlete training 30 hours weekly with the impact stress unique to boxing, managing inflammation becomes as important as building strength. The anti-inflammatory properties complement Joshua's protein and recovery supplements by addressing a different aspect of the adaptation and repair process.
For comprehensive joint and bone health, pairing omega-3s with collagen support provides both anti-inflammatory benefits and structural protein. XV1's Liquid Collagen delivers hydrolyzed Type I and III collagen peptides with hyaluronic acid, biotin, and zinc.
Building Complete Wellness: The XV1 Advantage
Anthony Joshua's supplement strategy demonstrates a fundamental truth about elite performance: success requires a comprehensive, science-backed approach that addresses multiple physiological systems simultaneously. While Joshua relies on Bulk™ products tailored for professional boxing, the principles underlying his stack—protein optimization, strategic recovery, cellular support, and foundational nutrition—apply universally to anyone seeking peak performance and long-term wellness.
XV1 was founded on these exact principles: delivering clinically-researched supplements that support complete wellness rather than isolated outcomes. Where Joshua's regimen addresses the extreme demands of championship boxing, XV1's product line serves the modern individual balancing demanding careers, fitness goals, and long-term health optimization. The parallel is clear—elite performance at any level requires addressing recovery, cellular health, energy, and foundational nutrition as interconnected systems.
