When should I take supplements for best results?

Creatine: any time, consistently. Caffeine: 30-60min pre-workout. Beta-alanine: split doses throughout day. Protein: within 2 hours post-workout. Magnesium: before bed.

Can supplements replace a good diet?

Never. Supplements provide 1-3% improvement at best. Elite athletes optimize: 1) Training, 2) Sleep, 3) Nutrition, 4) Recovery, then 5) Supplements. The basics matter most.

What about pre-workout supplements?

The only proven ingredients are caffeine (3-6mg/kg), beta-alanine (3g+), and citrulline (6-8g). Most pre-workouts underdose these and add fillers. DIY is often better.

What to Avoid or Limit

Antioxidants around training. May blunt training adaptations - save for competition
NSAIDs chronically. Impairs muscle and tendon healing
Proprietary blends. Can't verify doses; may contain banned substances

Lifestyle Factors

Supplements work best when combined with lifestyle awareness. These factors significantly affect nutrient needs for athletes & active adults.

Protein timing: 20-40g within 2 hours post-workout optimizes synthesis

Sleep is the ultimate recovery supplement - prioritize 8+ hours

Hydration: monitor urine color; electrolytes matter for 60+ min efforts

Periodize supplements like training - some for adaptation, others for competition

Special Considerations

1.Get tested for iron, vitamin D, and ferritin annually
2.Use third-party tested supplements (NSF Certified for Sport, Informed Sport)
3.Caffeine tolerance develops - cycle off periodically
4.Creatine works better with consistent loading vs cycling

Frequently Asked Questions

No. Loading (20g/day for 5-7 days) saturates muscles faster but causes GI issues for some. 5g daily reaches the same saturation in 3-4 weeks with no side effects.
