Creatine Loading vs. Maintenance: Which Strategy Is Better?

What Is Creatine and Why Is It the Most Researched Supplement in the World?

Creatine is a natural compound produced by the body from amino acids (arginine, glycine, methionine) and obtained from food — primarily red meat and fish. Muscles store creatine as phosphocreatine (PCr), which is the body's fastest energy source for intense, short-duration efforts.

Creatine has been studied in over 500 scientific studies and is one of the few supplements whose effectiveness is conclusively proven:

• Strength gain: 5-15% improvement in strength parameters (Rawson & Volek, 2003)
• Muscle growth: 1-2 kg additional mass in the first weeks (water + muscle)
• Endurance: Better performance in repeated sprint efforts (Buford et al., 2007)
• Brain function: Studies show improved cognitive performance (Avgerinos et al., 2018)
• Recovery: Faster recovery between workouts

Creatine monohydrate is the gold standard — the most studied, effective, and affordable form. Other forms (HCl, ethyl ester, buffered) have not shown better results.

What Is a Creatine Loading Phase and How Does It Work?

The loading phase is a strategy where creatine is taken in higher doses during the first 5-7 days to quickly saturate muscle creatine stores.

Traditional loading protocol:

• Phase 1 (loading): 20 g creatine monohydrate per day, split into 4 doses (4x5 g), for 5-7 days
• Phase 2 (maintenance): 3-5 g per day continuously

How it works:

Muscles can store a limited amount of creatine. In a normal state, muscles are ~60-80% full. The loading phase saturates stores to 100% within ~5 days.

Without loading, reaching the same level with 3-5 g daily takes ~3-4 weeks.

Scientific evidence:
Hultman et al. (1996) showed that 20 g/day for 6 days increased muscle creatine content by 20-40%. The same result was achieved with 3 g/day, but only after 28 days.

Is a Loading Phase Actually Necessary?

Short answer: not necessary, but accelerates results.

Loading phase advantages:

• Creatine stores fill in 5-7 days (vs. 3-4 weeks)
• You notice strength gains sooner
• Useful when you want fast results (e.g., before a competition period)

Loading phase disadvantages:

• Digestive issues (bloating, gas, diarrhea)
• Greater weight gain in the first days (water retention)
• More creatine consumed (lower cost-efficiency)
• Uncomfortable for some (4x5 g per day)

What does science say?

International Society of Sports Nutrition (ISSN) position stand (Kreider et al., 2017):

• Loading phase is effective for rapidly saturating creatine stores
• However, 3-5 g/day is sufficient to achieve the same results long-term
• Both protocols are safe and effective

What Is the Optimal Creatine Maintenance Dose?

If you decide to skip the loading phase (which is perfectly reasonable), here are the guidelines:

Standard dose: 3-5 g creatine monohydrate per day

Body weight-based dosing:

• Under 70 kg: 3 g per day
• 70-90 kg: 4 g per day
• Over 90 kg: 5 g per day

Timing:
This is a much-debated question. Science says:

• Before vs. after workout: Both work similarly
• On training days: Take before or after workout (with carbs and protein, which improve absorption)
• On rest days: Take anytime during the day
• Most important: Consistency! Take every day, not just on training days

What to take it with?

• With carbohydrates (insulin promotes creatine transport to muscles)
• With a protein shake (convenient and effective)
• With food (improves absorption)

Do You Need to Cycle Creatine (On/Off Periods)?

This is one of the most common creatine myths. Answer: no, you don't.

Why not:

• Long-term studies (up to 5 years) show no negative side effects from continuous use (Kreider et al., 2017)
• Cycling means losing loading benefits and having to restart
• ISSN recommends continuous use

Exceptions where cycling might be considered:

• Weight-class sports (wrestling, boxing) — creatine water retention may affect weight class
• Individual preferences — some people simply prefer cycles

What Are Creatine's Side Effects and Myths?

Actual side effects (rare and mild):

• Water retention: 1-3 kg weight gain (water in muscles, not fat). This is actually a desired effect — muscles are hydrated and larger.
• Digestive issues: Only with large doses (>10 g at once). Solution: split into smaller doses.
• Muscle cramps: Myth! Studies don't support this. Creatine may actually reduce cramps. Still, drink enough water and add magnesium.

Myths that are NOT true:

"Creatine damages kidneys" — Over 500 studies show no kidney damage in healthy individuals. Creatinine (a creatine breakdown product) rises in blood tests, but this does NOT mean kidney damage. Exception: people with existing kidney disease should consult a doctor.

"Creatine is a steroid" — Creatine is an amino acid compound, not a hormone. It's a natural substance the body produces. WADA does not ban creatine.

"Creatine causes hair loss" — One study (2009) showed a DHT increase, but subsequent studies did not confirm it. Current evidence-based position: no link between creatine and hair loss.

"Creatine is only for young people" — Studies show benefits for elderly (50+) too — maintaining muscle and bone health. Cognitive function improvement in the elderly.

How Do You Combine Creatine with Other Supplements?

Excellent combinations:

• Creatine + protein powder: Classic post-workout shake. Protein + creatine + carbs.
• Creatine + magnesium: Magnesium supports ATP production (the same system creatine uses). 300-400 mg in the evening.
• Creatine + vitamin D: Vitamin D supports muscle function. 2000-4000 IU in Estonian winter.
• Creatine + omega-3: Omega-3 reduces inflammation, creatine improves strength. Complementary effect.
• Creatine + ashwagandha: Ashwagandha supports testosterone and recovery. Studies show greater strength gains when combined with creatine.

Combinations with no conflict but no extra synergy:

• Creatine + BCAAs — BCAAs are unnecessary if protein is sufficient
• Creatine + L-carnitine — different mechanisms, no interaction

Summary: Which Creatine Strategy Should You Choose?

Our recommendation for most trainees:

1. Choose creatine monohydrate — cheapest and most effective form
2. Start with 5 g per day — no loading needed
3. Take every day — including rest days
4. With food — improves absorption
5. Drink enough water — minimum 2-3 liters per day
6. Be patient — stores are full after 3-4 weeks
7. Don't stop — continuous use is safe and effective

Creatine is one of the few supplements that truly works. Don't overcomplicate it — 5 g per day, every day, and results will come.
