Optimum Nutrition vs MyProtein: The Full Breakdown
Choosing between Optimum Nutrition (ON) and MyProtein creatine is one of the most common dilemmas Malaysian supplement buyers face.
ON commands brand prestige and third-party certification, while MyProtein consistently undercuts on price. Both sell creatine monohydrate — the most researched form of creatine (Kreider et al., 2017) .
Head-to-Head Comparison
| Feature | Optimum Nutrition | MyProtein |
|---|---|---|
| Creatine Form | Micronized Monohydrate (Creapure) | Monohydrate |
| Serving Size | 5 g | 5 g |
| Third-Party Tested | Informed Sport | Batch tested |
| Price (500 g) | RM 95–120 | RM 55–75 |
| Cost Per Serving | RM 0.50–0.80 | RM 0.30–0.50 |
| Halal Status | No formal cert | No formal cert |
| Malaysia Availability | Shopee, Lazada, retail | Shopee, Lazada, MyProtein MY |
| Flavour Options | Unflavoured | Unflavoured, Berry Blast |
| Mixability | Excellent (micronized) | Good |
| Country of Origin | USA / Germany (Creapure) | UK |
Purity and Quality
ON uses Creapure-sourced creatine monohydrate manufactured in Germany, widely regarded as the gold standard for purity.
The original phosphocreatine research by Harris et al. confirmed that creatine monohydrate effectively raises intramuscular creatine stores (Harris et al., 1992) .
MyProtein sources its creatine from multiple suppliers.
While no published reports indicate contamination, MyProtein does not carry the same Informed Sport certification that ON holds.
For competitive athletes subject to drug testing, ON provides an extra layer of assurance.
Value Analysis for Malaysian Buyers
At current Malaysian retail prices, MyProtein offers roughly 35–40% savings per serving compared to ON. Over a six-month supplementation cycle at 5 g daily, that translates to:
- ON total cost: approximately RM 90–144
- MyProtein total cost: approximately RM 54–90
The savings are meaningful, especially for students or those on tight budgets. However, the ON premium buys you Creapure certification and Informed Sport testing.
Who Should Buy Which?
Choose Optimum Nutrition if:
- You are a competitive or tested athlete
- You want Creapure-certified sourcing
- You prefer a brand with decades of market presence
- Mixability and micronized texture matter to you
Choose MyProtein if:
- Budget is your primary concern
- You are a recreational gym-goer
- You want direct-to-consumer pricing
- You are comfortable without Informed Sport certification
The Bottom Line
A thorough review of creatine supplementation confirms that all creatine monohydrate delivers the same performance benefits regardless of brand (Roschel et al., 2021) .
The choice between ON and MyProtein comes down to certification needs and budget.
Malaysian buyers get excellent value from either option — ON for certified peace of mind, MyProtein for maximum savings.

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
