What are the best supplements for lifters UK?

Twelve products on the lifter's shelf and the four rules that remove nine of them, applied in order

What are the best supplements for lifters in the UK is a question every shelf answers by addition, stacking products until the basket is full, and this guide answers it by subtraction, because the honest cupboard is what survives removal rather than what accumulates. Start with the twelve products most often sold to people who lift: protein powder, creatine, caffeine or a pre-workout blend, branched-chain amino acids, beta-alanine, citrulline, a testosterone booster, a zinc and magnesium formula, a fat burner, a multivitamin, vitamin D and magnesium. Then apply four rules in order, each removing what fails it. Rule one: remove anything with no authorised claim and no trial on a lifting outcome, strength, lean mass, reps or recovery. The testosterone booster goes first, since the 2020 audit of fifty found under a quarter with any data on testosterone and none on mass, and no claim exists. The fat burner goes, a caffeine and green tea blend with no authorised fat-loss claim and trials measuring tenths of a kilogram at best. The branched-chain amino acids go, since the only lifting trials in people eating enough protein are null and the nutrient they contain is protein, which has its own line. Three removed. Rule two: remove anything whose effect belongs to a nutrient the lifter already eats enough of. Protein powder goes conditional: the 2018 meta-analysis found its 0.3 kilograms of fat-free mass only when total intake was below about 1.6 grams per kilogram, so a lifter eating that from food removes the powder and a lifter who does not keeps it. The multivitamin goes for a lifter on a varied diet, since the vitamins it carries are claim-holders only for the deficient and a varied diet leaves few. The zinc and magnesium formula goes as a formula, because its zinc is rarely short in a meat-eating lifter and its magnesium is better bought as magnesium at a stated elemental dose. Three more removed or made conditional.

Rule three: remove anything whose benefit is for a sport the lifter does not do. The international consensus on performance supplements lists five with good evidence, caffeine, creatine, nitrate, beta-alanine and sodium bicarbonate, and three of the five are for efforts a lifter never makes. Beta-alanine buffers acid in efforts of one to four minutes, the 400 metres and the rowing piece, and does nothing measurable for a set of five; citrulline and nitrate improve endurance and time to exhaustion in continuous efforts and have a handful of extra reps in high-volume trials that do not survive a lifter's rest periods; bicarbonate is for the same minute-scale efforts and brings its own gut problems. Beta-alanine and citrulline go, and nitrate was never on the shelf. Rule four: remove anything priced above what its evidence is worth. The pre-workout blend goes here rather than earlier, because its evidence is real and belongs entirely to its caffeine: 150 to 300mg a serving, which carries an authorised claim for alertness and attention and improves reps and perceived exertion at 3mg per kilogram, sold in a tub with beta-alanine for the tingle, citrulline for the pump and a proprietary blend for the label, at ten times the price of the same caffeine as a tablet or a coffee. The caffeine stays and the blend goes. Nine of twelve removed or made conditional, by rules a lifter can apply to anything new the shelf produces next year.

What survives: three products and two conditionals, priced as a cupboard, with the worked example and the reason the shelf was built to prevent this answer

What survives the four rules is three products and two conditionals, and the cupboard they make costs under forty pence a day. Creatine monohydrate survives every rule: an authorised claim for physical performance in successive short bursts of high-intensity exercise at 3g a day, the longest mark on the lean-mass ruler at one to two kilograms over a block, a nutrient a lifter cannot eat enough of from food without a kilogram of red meat a day, evidence in exactly the sport a lifter does, and a price of a few pence a day as the plain powder with a purity statement. Caffeine survives as caffeine rather than as a blend: an authorised claim at 75mg for alertness and attention, 3mg per kilogram before the sessions that need it and not before the ones that do not, so that the tolerance which eats the effect never builds, at a penny a dose as a tablet. Magnesium survives on rule two's other side: the national diet survey finds a large share of young men below the lower reference intake, which makes it the one mineral a lifter is likely to be short of, and its authorised claims, normal muscle function, normal protein synthesis, electrolyte balance, normal nervous system function and the reduction of tiredness and fatigue, are the claims a lifter reads, at a stated elemental dose and a price in pence. The two conditionals are protein powder, kept only by the lifter whose food does not reach 1.6 grams per kilogram and bought by the gram of protein against the high protein threshold, and vitamin D, kept through the UK winter when skin synthesis stops, at a stated dose with its authorised claims for normal muscle function and bones.

Priced as a cupboard: creatine at three to five pence, caffeine at a penny on the days it is used, magnesium at 22p, vitamin D at a few pence in season, and protein powder at whatever the shortfall in grams costs, usually under a pound a serving when it is needed at all. Under forty pence a day for everything with a claim or a lifting trial behind it, which is the answer the question wanted and the one the shelf was built to prevent, since a shelf that sold the survivors alone would sell three commodities at pence and the industry around lifting runs on the nine that were removed. The worked example is the survivor with the claims a lifter actually reads: {FL}, 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV, two capsules with the evening meal, carrying the authorised claims for normal muscle function, normal protein synthesis, electrolyte balance, normal nervous system function and the reduction of tiredness and fatigue and no others, batch tested for lead, mercury, arsenic and cadmium, UK made under GMP and BRC, 180 capsules for £19.99 at 22p a day. The best supplements for lifters in the UK are the three that survive four rules and the two that survive them conditionally, and the rules are worth more than the list, because the shelf will have twelve new products next year and the rules will remove nine of those too.

Questions people also ask

What is the best supplement for weightlifting?

Creatine monohydrate, which survives every removal rule: an authorised claim for physical performance in successive short bursts of high-intensity exercise at 3g a day, the longest mark on the lean-mass ruler at around one to two kilograms over a training block, evidence in exactly the sport a lifter does, a nutrient that cannot be eaten in sufficient quantity from food, and a price of a few pence a day as the plain powder with a purity statement; nothing else on the shelf matches it on all five.

What supplements should a powerlifter take?

The same three survivors and two conditionals as any lifter, creatine monohydrate, caffeine before the sessions that need it, magnesium at a stated elemental dose, protein powder only if food falls short of 1.6g per kilogram, and vitamin D through the winter, with two additions decided by the federation: a tested powerlifter buys only batch-certified products and checks lot numbers, and a lifter making weight manages the day with food and fluid rather than with a fat burner, which rule one removes for everyone.

Are pre-workouts worth it for lifters?

Their evidence is real and belongs entirely to their caffeine, 150 to 300mg a serving, which carries an authorised claim for alertness and attention and improves reps and perceived exertion at 3mg per kilogram; the beta-alanine provides the tingle and buffers efforts of one to four minutes a lifter never makes, the citrulline provides a pump with no lifting trial behind it, and the proprietary blend provides the label, all at around ten times the price of the same caffeine as a tablet, so the fourth rule removes the blend and keeps the caffeine.

Do lifters need a multivitamin?

Not on a varied diet; the vitamins a multivitamin carries are claim-holders only for people short of them, and a lifter eating meat, fish, dairy, eggs, vegetables and grains is short of few; the two nutrients the national diet survey finds young men commonly below reference intakes for are magnesium and, in winter, vitamin D, and both are better bought as themselves at a stated dose than inside a formula that spreads a small budget across twenty nutrients the lifter already has.

How much should a lifter's supplements cost per day?

Under forty pence for everything with an authorised claim or a lifting trial behind it: creatine monohydrate at three to five pence, caffeine at a penny on the days it is used, magnesium at a stated elemental dose at around 22p, vitamin D at a few pence in season, and protein powder only when food falls short, at whatever the missing grams cost; a cupboard costing pounds a day has bought the nine products the four rules remove, and the rules will remove next year's nine as well.
