Which supplement is best for beginners?

Spend the first fifty pounds in the order the returns run: a programme at nothing, food for the protein gap, and why those two come before any tub

Which supplement is best for beginners is a question a beginner usually asks with a budget in mind and a shelf in view, and the answer is clearer if the budget is spent in the order the returns run rather than in the order the shelf presents. Take fifty pounds as the sum. The first purchase costs nothing: a programme. Beginner gains come overwhelmingly from the nervous system learning the lifts, from recruiting more of the muscle and coordinating it better each session, which is why a beginner adds weight to the bar every session for months, and that process is driven by a programme that practises a small number of compound lifts, adds load on a schedule, and is followed rather than changed. There are several free, well-constructed beginner programmes that do this and have done it for millions of people, and the difference between a beginner on one of them and a beginner improvising on machines is larger than the difference any supplement has ever produced in anyone. The first return is the largest and it is free, which is why the shelf never mentions it.

The second purchase is food, and it takes most of the fifty pounds. The largest nutritional gap a beginner has is protein: most people arriving at a gym eat around a gram per kilogram of body weight a day, and the lifting guidance's figure, above which the meta-analyses found no further gain in lean mass, is about 1.6g per kilogram, so a seventy-kilogram beginner is around forty grams a day short, which is a tin of fish, a few eggs and a pot of yoghurt. Closing that gap is the biggest nutritional change a beginner will ever make and it costs the price of groceries; a protein powder is a reasonable way to close the last of the gap on days the plate falls short, but it is a food purchase rather than a supplement one and it comes after the plate has been tried. Calories matter too, since a beginner who is underweight and trying to gain needs a modest surplus and one who is overweight can build muscle in a deficit, but protein is the gap most beginners have and the one with the clearest figure.

Why these two come before any tub is a matter of arithmetic the beginner is uniquely placed to misread. A beginner's rate of progress is the fastest it will ever be, which means that any supplement effect smaller than that rate is invisible: the beginner cannot tell whether the extra five kilograms on the squat this month came from the capsule or from being a beginner, and will credit the capsule, because they paid for it. Only an effect large enough to be seen over the beginner's own progress is worth buying, and only one supplement has one, which is the third purchase and the next section.

Two purchases that are free or food, and the third that is the one supplement, the fourth that is nothing, and the two things a beginner never buys, which is the next section.

Creatine as the third purchase and why it is the only one, nothing as the fourth, the two products a beginner never buys on any budget, the under-18 note, the worked example, and the verdict

The third purchase is creatine monohydrate, and it is the best supplement for beginners because it is the only one whose effect survives being hidden. The meta-analyses give it one to two kilograms of lean mass and a few percent on strength over a training block on top of training alone, which is large enough to show even against a beginner's rate of progress, and it has an authorised claim for physical performance in repeated short bursts of high-intensity exercise, the most studied safety record of any supplement, and a price in pence a day for plain monohydrate powder. A beginner takes 3 to 5g every day, including rest days, with a meal, and does not load unless they want the store full in a week rather than after a count of around twenty-eight doses; they expect a kilogram of water in the first days and the real effect over the block; and they buy the plain powder rather than a blend, a flavoured premix or a hydrochloride at ten times the price, because every trial used the plain powder. With a programme, food and creatine, the fifty pounds is spent and the beginner has bought everything that will move them.

The fourth purchase is nothing, and the reason deserves a sentence because the shelf is built to sell it. Every other product sold to a beginner, the pre-workout, the BCAAs, the mass gainer, the fat burner, the testosterone booster, the greens powder, the multivitamin without a reason, the joint formula, has an effect that is either zero or far smaller than a beginner's own progress, which means the beginner cannot measure it and will attribute their progress to it anyway, which is the mechanism by which a lifelong supplement habit is formed in the first month. A beginner who buys nothing fourth has saved the money and, more importantly, has learned to attribute progress to the programme and the plate, which is the correct attribution for the rest of their lifting life.

Two products a beginner never buys on any budget. The first is anything sold for testosterone, hormones or anabolic effect, because the lawful products do nothing to the hormone and the unlawful ones are the one category of product that will do a beginner lasting harm, and a beginner has no business near either. The second is a pre-workout taken to train through tiredness, because a beginner who needs a stimulant to train is a beginner whose sleep, food or programme is wrong, and the stimulant hides the problem for exactly as long as the tolerance takes to build. The under-18 note belongs here and is not optional: a beginner under eighteen takes no supplement on the strength of a web page, including creatine, and talks to a parent, a coach and a doctor, because the trials were run in adults and because a teenager's programme and plate are the whole answer.

The worked example is placed where a beginner's plate puts it, not as the fourth purchase: {FL}, 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV, two capsules with the evening meal, a mineral the national diet survey finds a share of young men short of, with authorised claims for normal muscle function and the reduction of tiredness and fatigue, batch tested for lead, mercury, arsenic and cadmium, UK made, 180 capsules for £19.99 at 22p a day, bought by a beginner whose diet is low in the foods that carry it, which a beginner eating a narrow plate may be, and not by one whose plate is already full. The full label breakdown is here.

The verdict: the best supplement for a beginner is creatine, bought third. A programme is bought first for nothing and food second for most of the money, because those two produce the gains a beginner will credit to whatever they bought, and creatine is the one supplement whose effect is large enough to be seen over them. Nothing is bought fourth, nothing hormonal is bought ever, and a beginner under eighteen buys nothing without a coach and a doctor.

What to check on the label

Questions people also ask

What is the one supplement a beginner should take?

Creatine monohydrate, at 3 to 5g a day every day with a meal, because it is the only supplement whose effect, one to two kilograms of lean mass and a few percent on strength over a block in the meta-analyses, is large enough to be seen over a beginner's own rapid progress, and because it has an authorised claim, the best-studied safety record of any supplement and a price in pence as plain powder; it is bought third, after a free programme and after food has closed the protein gap, because those two produce the gains the beginner will otherwise credit to the tub.

Should a beginner take protein powder?

Only for the shortfall, after the plate has been tried: most beginners eat around a gram of protein per kilogram a day and the lifting guidance's figure is about 1.6g, so a seventy-kilogram beginner is around forty grams short, which groceries close for less than a powder does; a powder is a reasonable way to cover the days the plate falls short and is a food purchase rather than a supplement one, which is why it sits inside the second purchase rather than being the first thing bought.

Do beginners need pre-workout?

No; a beginner who needs a stimulant to train is a beginner whose sleep, food or programme is wrong, and the stimulant hides the problem for exactly as long as tolerance takes to build, while the one ingredient in a pre-workout that works, caffeine, is available as a tablet of known dose for the rare session where it is wanted; a beginner's progress is fast enough that any pre-workout effect is invisible against it, which makes it an unmeasurable purchase and the kind the shelf is built to sell.

Is creatine safe for a beginner?

In adults, yes, with the most studied safety record of any supplement: long-term trials at 3 to 5g a day found no effect on kidney or liver function in healthy people, the documented effects being a kilogram of water drawn into the muscle in the first days and a raised creatinine marker that is a laboratory artefact; a beginner under eighteen is a different case, because the trials were run in adults and a teenager's programme and plate are the whole answer, so they take nothing on the strength of a web page and talk to a parent, a coach and a doctor.

Should a beginner take magnesium?

Only if their plate is short of it, which a beginner eating a narrow diet may be: the national diet survey finds a share of young men below the reference intake, and magnesium has authorised claims for normal muscle function and the reduction of tiredness and fatigue; the worked example is 300mg elemental at 80% NRV in two capsules with the evening meal for 22p a day, batch tested for four metals and UK made, bought when the plate is short and never as the fourth purchase after the programme, the food and the creatine.
