Creatine Guide: How Much to Take, Which Form to Buy, and Why (NZ)

What is creatine?

Creatine is the fuel your muscles use for short, hard efforts — a heavy set, a sprint, a jump — and a 3–5 g daily supplement keeps that tank full. Your body makes some and meat and fish add some; most of it sits in muscle as phosphocreatine, a fast-access energy reserve. Vegetarians usually start with less of it, which is one reason they often notice a larger change when they supplement.

Creatine monohydrate is the most-studied form and the one most of the research is built on. It is not a steroid, not a stimulant, and not related to caffeine — it is a compound your muscles already use every day. Every creatine product on our shelves supplies this same compound; the formats differ in how it is bound, mixed and taken.

How does creatine work?

Creatine works by keeping your muscles' quick-charge battery — phosphocreatine — topped up. Hard efforts drain your muscles' immediate energy (ATP) in seconds; phosphocreatine recharges it on the spot, so a bigger store means one more hard rep or a few more metres at full pace before fatigue sets in.

That is why creatine shows up in strength, power and repeated high-intensity work — lifting, sprints, team sport — and not in steady, low-intensity exercise, where a different energy system does the work. It is not a stimulant: you don't feel it kick in; you see it in your training numbers over weeks.

What does creatine do for training?

Creatine monohydrate supports more strength, more power and more quality reps over a training block — the International Society of Sports Nutrition's 2017 position stand rates it among the most effective performance supplements studied. By outcome:

• Strength and power: supports maximal strength and repeated high-intensity efforts during structured training.
• Training volume and lean mass: by supporting higher-quality sessions, creatine can indirectly support lean-mass gains over a training block.
• Women, vegetarians and older adults: the research covers both sexes, and people with lower baseline muscle creatine — many vegetarians, older adults — often see a larger relative benefit.

Where it does less: pure steady-state endurance events (runners, see our Running Fuel guide). And because creatine draws a little extra water into muscle, expect a small rise on the scales — water in muscle, not fat, and worth knowing in a weight-class sport. Every format in the next sections delivers these same effects; the choice is about how you'll take it.

How much creatine should you take?

The daily dose of creatine monohydrate is 3–5 g, at any time of day, every day including rest days — consistency matters more than timing. Taking it with carbohydrate may support uptake in some protocols, but it isn't required. Creatine HCL products are dosed by bodyweight instead; the label on the tub gives the chart.

Missed a day? Just carry on. Muscle stores fall slowly — over weeks, not days — so one missed dose changes nothing. Take it whenever you'll remember: with breakfast, in a shake, or with dinner. Powder gives you full control of the dose; capsules, tablets and gummies pre-measure it for you.

Do you need to load creatine?

No — a creatine loading phase is optional. Loading (around 20 g a day in split doses for 5–7 days) fills muscle creatine stores in about a week; 3–5 g a day gets to the same point in around 3–4 weeks. Load if you want it faster, or keep it simple with the daily dose.

What you'll notice, and when. Nothing on day one — creatine is not a stimulant. As stores fill, look for an extra rep or two on hard sets and better-quality sessions, not a feeling. If a loading dose sits heavily, skip loading and take 3–5 g a day, or split the loading dose across meals.

Which creatine is right for you? Monohydrate, HCL, capsules, gummies and blends

The right creatine format depends on how you'll take it: plain monohydrate powder for value, flavoured for taste, capsules for convenience, gummies for the easiest habit, HCL for a small serve that mixes clear. Every one of them gets creatine into your muscles; creatine monohydrate is the most-studied form and the default, and the rest exist because people mix, swallow and stick to routines differently. Powder gritty? Stir it into warm water or a shake, or pick a micronised powder or HCL.

The formats on our shelves

You may see buffered or nitrate forms on other shelves; the formats above are what you'll find at Xplosiv, in-store and online.

How to choose in 30 seconds

Choosing a creatine at Xplosiv takes four questions: mix or swallow, plain or flavoured, small serve or standard, calories or not.

• Mix, swallow or chew?Mix → a monohydrate powder. Swallow → capsules or tablets. Chew → gummies or chews.
• Plain or flavoured?Plain → unflavoured monohydrate, the best value per gram. Flavoured → a flavoured monohydrate or a blend.
• Want a small serve that mixes clear, or does monohydrate sit heavily?→ Creatine HCL, powder or capsules, dosed by bodyweight.
• Want the calories with it after training, or everything in one scoop?Calories → a creatine + carbohydrate formula. One scoop → a multi-form blend.

Whatever you pick, take it every day. All of these formats are available online and in Xplosiv stores nationwide, with click & collect. Browse the creatine range.

Is creatine safe? What the research says

Creatine is one of the most-studied supplements in sports nutrition, and daily use at 3–5 g is well tolerated by healthy adults. The common worries, against the evidence:

• Kidneys? At standard doses creatine has not been shown to impair kidney function in healthy adults. It can raise blood creatinine, a test marker, without that meaning kidney injury. If you have a kidney condition, check with a health professional first.
• Hair? A 12-week randomised controlled trial (Lak 2025; 45 resistance-trained men, 5 g a day) found no difference in hair outcomes between creatine and placebo.
• Cramping or dehydration? Research does not support creatine as a cause of cramping or dehydration at recommended doses. Drink to thirst as you normally would; there is no gallon-a-day rule.
• Scale weight? Creatine draws a little extra water into muscle, which can show as a small rise on the scales — water in muscle, not fat.
• Cycling off? Not required. A daily 3–5 g keeps stores topped up; there is no need to stop and start.

This guide is for general education only and is not medical advice. Creatine supplements are not medicines and are not intended to diagnose, treat, cure, or prevent any disease. If you are pregnant, breastfeeding, under 18, have a kidney condition or other medical condition, or take prescription medicines, talk to a qualified health professional before use. Competitive athletes should check current anti-doping advice for their sport.

Buying creatine in New Zealand

Every format in this guide is available online at xplosiv.nz and in Xplosiv stores across New Zealand, with click & collect so you can pick up same-day rather than wait on a courier. If you follow a vegetarian diet — common among Kiwi gym-goers cutting back on red meat — you likely start with lower muscle creatine than a meat-eater, and that profile often sees a larger relative benefit from supplementing.

If you compete under a sporting body's anti-doping code, creatine itself is not a banned substance; check your sport's current advice and look for third-party tested options, which you can filter for on the creatine category page.
