Creatine comes down to 5g of monohydrate — and skipping the loading phase
In short
Choosing a creatine supplement comes down to three checks: the form should be monohydrate, the serving should be 5 grams, and the tub should carry third-party certification such as NSF Certified for Sport or Informed Sport. The loading phase many brands recommend — 10 grams or more daily in the first week — is not supported by convincing enough research to justify burning through the extra servings. Patented raw materials cost more, and research comparing them to other certified monohydrate remains inconclusive.
The creatine shelf looks complicated until you turn the tubs around, at which point most of them say the same thing: 5 grams of micronised creatine monohydrate. What separates products is not that ingredient but everything bolted around it.
What is actually worth comparing?
- Form — monohydrate. The most researched form and the reference point.
- Serving size — 5 grams, which is effectively the standard across every product.
- Third-party testing — NSF Certified for Sport, Informed Sport, USP. It means an outside body confirmed the label matches the contents and nothing banned got in.
- Added ingredients — HMB, flavours, sweeteners. Usually added for differentiation rather than because anything needed them.
"Micronised" means the particles have been made finer, so the powder clumps less and dissolves more easily in water, coffee or a shake. That is a drinking-experience question, not an efficacy one — non-micronised products simply need more stirring.
Do you need a loading phase?
Plenty of brands recommend 10 grams a day, or more, for the first week. But the research exploring the need for a loading phase is not convincing enough to burn through several additional servings. Taking 5 grams daily is simpler and gets to the same place.
Are the premium raw materials worth it?
Some patent-protected micronised monohydrate ingredients emphasise their purity and safety documentation, and they generally arrive with a higher price tag. Research comparing them against other certified forms of creatine monohydrate is inconclusive. If you pay more, pay for confidence in a company's testing, not for expected performance.
The spread is real. For the same 5 grams of monohydrate, cost per serving ranges from around 33 cents to 96 cents — close to three times. Read the per-serving cost alongside the tub size, and buy a quantity you will finish before the best-by date.
Anyone with kidney disease or abnormal renal function tests should discuss creatine with a doctor before starting. It has a long safety record in healthy adults, but with an underlying condition that call belongs to a clinician.
How this relates to your strength score
Starting creatine draws water into muscle, so bodyweight rises first. A relative strength score is corrected for bodyweight, which means it can dip during the first few weeks — before the lifts have moved. Nothing got weaker; the denominator moved first. Skipping the loading phase makes that weight change gentler and the data less jumpy. When you start creatine, log your bodyweight and your Big 3 on the same day, so that stretch is readable later.

Frequently asked questions
How much creatine should you take per day?
5 grams is effectively the standard serving across every product, taken daily and consistently. The first-week loading phase brands recommend is not supported by convincing enough research.
Do you need a creatine loading phase?
No. Many brands recommend 10 grams a day or more for the first week, but the research exploring the need for loading is not convincing enough to justify burning through the extra servings. Taking 5 grams daily is simpler.
Which form of creatine should you choose?
Monohydrate. It is the most researched form and the reference point, and "micronised" relates to how well it dissolves rather than how well it works. Added ingredients such as HMB or flavourings are generally there for differentiation.
Are expensive patented creatine ingredients more effective?
There is no conclusion to that effect. Research comparing patent-protected micronised monohydrate to other certified forms of monohydrate is inconclusive, while the price is often higher.
Does creatine make you gain weight?
Bodyweight rises early as water is drawn into muscle. A bodyweight-corrected strength score can therefore dip temporarily during that period — not because strength fell, but because bodyweight moved first.
