Q: What's the best supplement stack for CrossFit?
A: CrossFit demands strength, endurance, and rapid recovery. Core stack: creatine (5g daily) + beta-alanine (3.2g daily) + MusclEAA Xtreme (intra-WOD) + Isoflex (post-WOD) + Omega 3.
CrossFit WODs are 5-25 minute glycolytic-aerobic efforts — neither pure strength nor pure endurance. Creatine handles short bursts (sprints, heavy lifts), beta-alanine buffers the 1-4 minute lactic-acid wall, and EAAs preserve muscle during high-volume training. Together, the stack addresses all three energy systems.

What to Look For
- Beta-Alanine timing: Daily consistency matters more than timing. 3.2g per day saturates muscle carnosine in 2-4 weeks.
- WODs over 20 min: Add 30-50g carbs pre-WOD for glycogen support.
- Recovery is the limiter: CrossFit volume tests recovery capacity. Sleep + protein + omega-3 are non-negotiable.
- Banned-substance testing: If competing, choose certified products (PVL IsoGold is Informed-Choice).
Frequently Asked Questions
Will creatine make me slower?
No. The slight water-retention is intramuscular, not cardiovascular. Strength and explosive power increase. Some experience minor weight gain (1-2 kg) which can affect bodyweight-class events.
Beta-Alanine tingling — is that safe?
Yes — harmless paresthesia at single doses above 1.6g. Splitting daily doses (1.6g twice daily) reduces tingling. Effects continue with consistent daily use.
Should I use carbs intra-WOD?
Only for WODs over 30 min. Shorter WODs run on glycogen + ATP-CP. Intra-WOD carbs help marathon-style metcons (Murph, 20-min AMRAPs).
What about pre-workout?
Stim or stim-free both work. For high-intensity WODs, moderate caffeine (100-200mg) is the sweet spot. Avoid mega-dose pre-workouts that cause GI issues during inverted/explosive movements.
Best post-WOD recovery shake?
1 scoop Isoflex (27g protein) + 1 scoop creatine + half banana for carbs. Mix in 8-10 oz cold water. Easiest 30g protein + 5g creatine on the planet.
