Why Load Creatine?
Creatine monohydrate is a compound found naturally in muscle cells that helps produce energy during heavy lifting or high-intensity exercise. A loading phase saturates your muscle creatine stores significantly faster (1 week vs 4 weeks).🚀 The Science: Phosphocreatine (PCr)
Your body uses ATP for energy. During explosive movements (1-10 seconds), ATP runs out. Creatine donates a phosphate group to turn ADP *back* into ATP. * More Creatine = More Reps = More Volume = More Growth.The Loading Protocol (First 5-7 Days)
Take 0.3 grams per kg of body weight (or ~0.14g per lb). Start big to fill the tank. * Example (180 lbs / 82kg): ~25g Total Daily. * Split It Up: Take 4 doses of ~6g to avoid stomach upset.📅 Loading vs. Maintenance
| Phase | Dosage | Duration | Purpose | | :--- | :--- | :--- | :--- | | Loading** | **20-25g / day | 5-7 Days | Saturate muscles fast | | Maintenance** | **3-5g / day | Indefinite | Keep levels topped off | | No-Load** | **3-5g / day | 30 Days | Slow saturation (no bloat) |The Maintenance Phase (Week 2 Onwards)
Once saturated, you only need to replace what you degrade daily. * Standard Dose: 3-5g per day. * High Responders: Larger athletes (>220lbs) may need 5-8g.💧 Hydration is Non-Negotiable
Creatine pulls water *into* the muscle cell (cell volumization). This is good (anabolic signal), but it requires water. * Drink 3-4 Liters of water daily during loading. * Cramping? You aren't "holding water," you are dehydrated. Drink more.Frequently Asked Questions
Q: Will I get bloated? A: "Bloat" is usually subcutaneous water (under the skin). Quality Creatine Monohydrate causes *intracellular* water retention (inside the muscle), making you look fuller and harder, not puffy.Q: Does creatine cause hair loss? A: One study in 2009 suggested a link to DHT. No study has ever replicated this. It is considered a myth by the ISSN.
Q: When should I take it? A: Post-workout with carbs is technically best for absorption (insulin spike), but consistency matters more than timing. Just take it daily.
常見問題 (FAQ)
Q: 肌酸安全嗎?有什麼副作用?
A: 肌酸一水化物是所有運動補充品中研究最多、安全性記錄最完整的品項。超過 1,000 篇人體研究顯示,正常劑量(3–5g/天)對腎臟健康成人是安全的。常見副作用:體重略微增加(細胞內水分增加 0.5–1.5 kg),部分人可能出現輕微腸胃不適(建議隨餐服用)。腎功能不全者請先諮詢醫師。
Q: 肌酸素食者可以使用嗎?
A: 可以,肌酸補充品通常是合成製造,不含動物成分(請確認標籤)。素食者天然飲食中肌酸攝取幾乎為零(肌酸主要來自肉類),因此補充效果可能優於肉食者,研究顯示素食者補充肌酸後認知和力量提升更顯著。
