Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

3-5g daily (or 20g/day x 5 days loading, then 3-5g maintenance)

Enhances power, strength, and repeated sprint ability critical for rugby

20 studies | 800 participants
3-6mg/kg body weight, 30-60 min before match/training

Improves alertness, power output, and reduces perceived exertion during high-intensity exercise

15 studies | 600 participants

Supporting Stack (Tier 2)

3-6g daily (divided doses)

Buffers lactic acid; supports repeated high-intensity efforts

10 studies | 400 participants
0.2-0.3g/kg body weight, 60-90 min before intense exercise

Buffers acid in blood; may enhance repeated sprint performance

8 studies | 300 participants
1.6-2.2g/kg/day total; 20-40g post-training

Essential for muscle repair and adaptation; high demands in contact sport

25 studies | 1,000 participants
2000-4000 IU daily

Supports muscle function, bone health, injury prevention; indoor athletes often deficient

10 studies | 400 participants
2-3g EPA+DHA daily

Anti-inflammatory; supports recovery from contact sport trauma; brain health

10 studies | 400 participants

How It Works

Rugby is a physically demanding contact sport requiring a combination of strength, power, speed, endurance, and the ability to recover from repeated impacts. Proper nutrition and supplementation can support these demands.

PHYSICAL DEMANDS:

•High-intensity running and sprinting
•Tackling and being tackled (contact)
•Scrummaging (forwards)
•Repeated explosive efforts
•80 minutes of play with minimal breaks

NUTRITIONAL PRIORITIES:

1. Adequate energy: Match the high caloric demands

2. Protein: For muscle repair and contact recovery

3. Carbohydrates: Fuel for training and matches

4. Hydration: Critical for performance

5. Recovery nutrition: Especially after contact sessions

EVIDENCE-BASED SUPPLEMENTS:

•Creatine: Most proven for power and repeated sprints
•Caffeine: Enhances alertness and power
•Beta-alanine: Buffers acid during intense efforts
•Protein: Essential for muscle repair

POSITION-SPECIFIC CONSIDERATIONS:

•Forwards: Higher body mass needs, more contact, strength focus
•Backs: Speed and agility focus, lighter body composition

CONTACT RECOVERY:

•Omega-3s may help with inflammation
•Adequate protein for tissue repair
•Sleep and rest are critical

ANTI-DOPING:

•Use only third-party tested supplements (Informed Sport, NSF Certified)

* Creatine and caffeine have strongest evidence.

* Protein needs are high due to contact and training demands.

* Recovery support with omega-3 and vitamin D.

Expected timeline: Creatine benefits in 1-2 weeks. Caffeine works acutely. Beta-alanine needs 2-4 weeks loading.

Muscle Size & Strength

5 shared supplements · 334 outcomes

This page on muscle size and strength covers strategies to maximize muscle gain and strength gain. There is notable overlap in nutrition and supplementation strategies to facilitate these two goals, but there is some divergence in the best type of exercise. A larger muscle tends to be a stronger muscle.

General Athletic Performance

General athletic performance refers to an individual's ability to perform in various sports and physical activities, including strength, speed, endurance, and agility.

Type 2 Diabetes

4 shared supplements · 868 outcomes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

Muscle Recovery

4 shared supplements · 219 outcomes

Muscle recovery refers to a reduction in muscle soreness or a return of a muscle’s range of motion, strength, or power to normal levels after fatiguing exercise or muscle damage. Muscle recovery is associated with reductions in markers of muscle damage and inflammation.
