Fish: A Rich and Varied Source of Creatine
Fish and seafood are among the richest dietary sources of creatine, with some species containing higher concentrations than red meat.
For Malaysia — a nation with over 4,600 km of coastline and a large fishing industry — seafood is a central component of the diet and a significant contributor to dietary creatine intake (Kreider et al., 2017) .
The creatine content in fish varies considerably by species, with some cold-water fish containing up to 10g per kg of raw flesh — the highest of any natural food source.
Creatine Content by Fish Species
High Creatine Fish (5-10g/kg raw)
| Fish Species | Creatine Content (per kg raw) | Availability in Malaysia |
|---|---|---|
| Herring | 6.5-10.0 g | Imported, limited |
| Salmon | 4.5-5.0 g | Imported, supermarkets |
| Tuna | 4.0-5.0 g | Common, fresh and canned |
Medium Creatine Fish (3-5g/kg raw)
| Fish Species | Creatine Content (per kg raw) | Availability in Malaysia |
|---|---|---|
| Mackerel (ikan kembung) | 3.5-5.0 g | Very common, affordable |
| Cod | 3.0-4.0 g | Imported |
| Plaice/flatfish | 3.0-4.0 g | Limited |
| Snapper (ikan merah) | 3.0-4.0 g | Common |
| Grouper (ikan kerapu) | 3.0-4.0 g | Common |
| Threadfin (ikan kurau) | 3.0-4.0 g | Common, premium |
Lower Creatine Seafood (1-3g/kg)
| Seafood | Creatine Content (per kg raw) | Notes |
|---|---|---|
| Prawns/shrimp (udang) | 1.5-3.0 g | Common in Malaysian cuisine |
| Squid (sotong) | 1.0-2.5 g | Popular, lower creatine |
| Crab (ketam) | 1.0-2.0 g | Seasonal, lower creatine |
| Shellfish | 0.5-2.0 g | Variable by species |
Popular Malaysian Fish and Creatine Content
Malaysians consume a wide variety of fish. Here is how common local fish compare in estimated creatine content:
| Malaysian Fish | Local Name | Estimated Creatine (per kg raw) |
|---|---|---|
| Indian mackerel | Ikan kembung | 3.5-5.0 g |
| Red snapper | Ikan merah | 3.0-4.0 g |
| Pomfret | Ikan bawal | 3.0-4.0 g |
| Grouper | Ikan kerapu | 3.0-4.0 g |
| Threadfin | Ikan kurau | 3.0-4.0 g |
| Spanish mackerel | Ikan tenggiri | 3.5-4.5 g |
| Sardines | Ikan sardin | 3.0-4.0 g |
| Catfish | Ikan keli | 2.5-3.5 g |
| Stingray | Ikan pari | 2.5-3.5 g |
| Tilapia | Ikan tilapia | 2.5-3.5 g |
Cooking Effects on Fish Creatine
How Malaysian Fish Preparations Affect Creatine
Different cooking methods retain different amounts of creatine (Harris et al., 1992) :
| Cooking Method | Retention | Malaysian Examples |
|---|---|---|
| Steamed | 75-85% | Ikan kukus, steamed fish with soy sauce |
| Grilled/bakar | 60-75% | Ikan bakar, BBQ fish |
| Fried | 55-70% | Ikan goreng, goreng tepung |
| Curry/stew | 55-70% | Kari ikan, gulai ikan |
| Asam pedas | 60-75% | Creatine leaches into sauce — eat the gravy |
| Sambal | 60-75% | Quick cooking preserves more creatine |
Tips to Maximize Creatine from Fish
- Choose steaming when possible — it retains the most creatine
- Eat the sauce/gravy from fish curries and asam pedas — it contains leached creatine
- Shorter cooking times preserve more creatine
- Sashimi and raw fish retain virtually all creatine (for those who consume raw fish)
Creatine from Fish in Malaysian Meals
Typical Meal Analysis
| Meal | Fish Portion | Estimated Creatine |
|---|---|---|
| Nasi campur with ikan kembung goreng | 100-150 g | 0.25-0.45 g |
| Ikan bakar with rice | 200-300 g | 0.40-0.70 g |
| Asam pedas ikan (with gravy) | 150-200 g | 0.35-0.55 g |
| Fish head curry | 200-300 g | 0.35-0.60 g |
| Ikan kukus (steamed) | 150-250 g | 0.40-0.75 g |
| Canned tuna sandwich | 80-100 g | 0.25-0.35 g |
| Sushi/sashimi | 100-150 g | 0.40-0.60 g |
Even the most fish-heavy meals provide fewer than 1g of creatine — a fraction of the recommended supplementation dose.
Fish vs. Beef vs. Chicken: Creatine Comparison
| Protein Source | Creatine per kg (raw) | Malaysian Consumption | Daily Creatine Estimate |
|---|---|---|---|
| Herring | 6.5-10.0 g | Rare | Minimal |
| Beef | 4.0-5.0 g | Moderate | 0.1-0.3 g |
| Fish (average) | 3.0-5.0 g | High | 0.2-0.5 g |
| Chicken | 3.0-4.0 g | Very high | 0.3-0.5 g |
The Supplementation Case
A typical Malaysian diet including regular chicken and fish consumption provides approximately 0.5-1.5 g of dietary creatine daily.
This contributes to basal creatine levels but falls significantly short of the 5g daily dose shown to optimize phosphocreatine stores in research.
The gap between dietary intake and optimal supplementation is 3.5-4.5 g daily — precisely what a creatine monohydrate supplement provides.
At RM 0.50-1.00 per day, supplementation is dramatically more efficient than trying to increase fish consumption to meet the target.
The Bottom Line
Fish is an excellent dietary source of creatine, with species like herring (6-10g/kg), tuna (4-5g/kg), and mackerel (3-5g/kg) ranking among the richest natural sources.
Malaysian fish like ikan kembung, ikan merah, and ikan tenggiri provide meaningful creatine, especially when steamed or consumed with their cooking liquids.
However, typical fish portions provide only 0.3-0.7g of creatine per meal — far below the 5g needed for optimal supplementation.
Enjoy fish for its excellent protein, omega-3, and nutrient profile, and supplement with creatine monohydrate for complete creatine optimization.

Mechanism of Action
Understanding the biochemistry behind creatine's effects provides context for the practical recommendations in this guide. Creatine functions primarily through the ATP-phosphocreatine (ATP-PCr) system:
- Storage: Approximately 95% of the body's creatine is stored in skeletal muscle, with the remaining 5% in the brain, kidneys, and liver
- Conversion: The enzyme creatine kinase attaches a high-energy phosphate group to free creatine, creating phosphocreatine (PCr)
- Energy release: During high-intensity activity, PCr rapidly donates its phosphate group to ADP, regenerating ATP within milliseconds
- Resynthesis: During rest periods, the process reverses — ATP donates a phosphate back to creatine, replenishing PCr stores
This cycle operates continuously in all metabolically active tissues. Supplementation increases the total creatine pool by 20-40%, expanding the energy buffer available for intense physical and cognitive work.
Evidence Quality Assessment
When evaluating claims about creatine, consider the hierarchy of evidence:
- Systematic reviews and meta-analyses — the strongest evidence, pooling data from multiple studies. Creatine has numerous favourable meta-analyses
- Randomised controlled trials (RCTs) — well-designed experiments with control groups. Creatine has 500+ published RCTs
- Observational studies — useful for identifying associations but cannot prove causation
- Case reports and anecdotes — the weakest evidence, useful for generating hypotheses but not for making recommendations
The recommendations in this article are based on level 1-2 evidence wherever possible.
Malaysian Context
For readers in Malaysia, several local factors are worth considering:
- Climate: Malaysia’s tropical heat (27-33 degrees Celsius average) and high humidity increase fluid requirements. Supplement creatine with 2.5-3.5 litres of daily water intake, more during intense outdoor activity
- Halal considerations: Unflavoured creatine monohydrate powder is synthetically produced and generally considered permissible. See our halal creatine guide for brand-specific verification
- Affordability: Creatine is one of the most cost-effective supplements available in Malaysia, starting from RM0.50 per serving. See our price comparison guide for current pricing
- Availability: Widely available through Shopee, Lazada, and specialty supplement shops across Peninsular Malaysia, Sabah, and Sarawak
