Private label pre-workout manufacturing: the label problem nobody warns you about

Pre-workout is one of the most profitable categories in sports nutrition and one of the easiest to get wrong on paper. Not because the formula is difficult — it is a well-understood combination of a stimulant, some performance actives and a flavour system — but because almost nothing the consumer buys it for can legally be said on the label. That gap between what the product does and what you are allowed to write is the single most important thing to understand before you manufacture one.

The short version

Short answer

None of the hero ingredients of a pre-workout has an authorised health claim in the EU. Caffeine, beta-alanine, citrulline, arginine, taurine, carnitine and glutamine do not appear in the authorised claims list at all. What does appear is the supporting cast: niacin, riboflavin, thiamine, vitamin B6, vitamin B12 and magnesium, with claims on normal energy-yielding metabolism, normal nervous-system function and — for magnesium — helping reduce tiredness and fatigue. So a compliant pre-workout label is built on the vitamins and minerals, exactly the way a collagen label is built on vitamin C. Separately, Annex III of Regulation (EU) 1169/2011 imposes additional mandatory particulars for high-caffeine products, which your manufacturer must compute for your serving and format.

Why the label is the hard part

In the EU, a health claim is not a sentence you write. It is a sentence that has been authorised, with fixed wording and conditions of use, and you either meet the conditions and use the authorised text or you say nothing. We covered the framework in health claims and supplement labelling in the EU.

Applied to pre-workout, that framework has a blunt consequence. We checked the authorised claims table published by AESAN, the Spanish competent authority, ingredient by ingredient:

IngredientAuthorised claims in the EU
CaffeineNone
Beta-alanineNone
CitrullineNone
ArginineNone
TaurineNone
CarnitineNone
GlutamineNone
Niacin (B3)Yes — energy metabolism, nervous system, and others
Riboflavin (B2)Yes — energy metabolism, nervous system, and others
Thiamine (B1)Yes — energy metabolism, nervous system
Vitamin B6Yes — energy metabolism, and others
Vitamin B12Yes — energy metabolism, nervous system, and others
MagnesiumYes — including helping reduce tiredness and fatigue

Read that table again from a marketing point of view. Every ingredient the consumer is paying for is silent, and every ingredient they ignore is the one that can speak.

This is not a loophole to exploit; it is the structure of the regulation, and the professional response is to design the formula so that the claims you want are actually available to you. That is the same logic collagen products follow when they add vitamin C — we described it in the private label collagen guide.

What that means for your formula

Three consequences that change formulation decisions, not just copy:

  1. The vitamin and mineral package is not filler. If you want to say anything about energy or fatigue on the front of the tub, the B vitamins and the magnesium have to be present at levels that meet each claim’s condition of use — typically that the product is at least a source of that nutrient. Under-dose them and the claim disappears, which means you have paid for the ingredient and lost the label.
  2. Your differentiation moves to where you are allowed to compete. Since you cannot out-claim a competitor on caffeine, you compete on the things the label can carry: the transparency of the actives list, the flavour, the format, the absence of things people avoid, and the brand itself.
  3. The stimulant dose is a labelling decision as much as a formulation one. Additional mandatory particulars apply above the caffeine thresholds set in Annex III of Regulation (EU) 1169/2011. We are deliberately not quoting the figure here — it must be read from the current consolidated text and applied to your specific serving and format — so make it an explicit question to your manufacturer’s regulatory team before artwork goes to print.

Formats: tub or sticks

Pre-workout is a flavoured, multi-gram powder, which narrows the format decision to two realistic options:

  • Flavoured powder in a tub. The category default. Lowest cost per serving, the consumer sees the volume they are buying, and it supports the scoop-based ritual that is part of the product’s appeal.
  • Single-serve sticks. The fastest-growing option, and a strong one for a new brand: they remove the dosing question, travel well, sell into pharmacy and convenience channels, and support a higher price per serving in a category where the customer cannot evaluate the formula and buys on presentation.

Both are standard formats in a powder plant, so this is a commercial decision rather than a technical constraint. The economics of each are in the most in-demand supplement formats, and format is the main driver of minimums — see the MOQ guide.

One technical note worth raising early with your manufacturer: pre-workout combines an acidic flavour system with hygroscopic actives, so flow, caking and packaging choice interact. Ask what has actually run on the line in your format and grammage, rather than what is theoretically possible.

What to ask a pre-workout manufacturer

Beyond the general checklist in how to choose a supplement manufacturer:

  • Who reviews the label before printing, and whether they compute the caffeine particulars for your serving.
  • Which vitamin and mineral levels the formula needs to keep the claims you want, quantified against each claim’s condition of use.
  • Certificate of analysis per batch, and what the specification covers for each active.
  • Anti-doping assurance, which matters more in pre-workout than in almost any other category if you sell to competing athletes — see supplement manufacturer capacity.
  • Flavour development: whether you are choosing from validated flavours already running or paying for development, which is the difference between private label and OEM.

Who launches private label pre-workout

  • Gyms and box chains, where the product is consumed on the premises and the brand is already trusted by the buyer.
  • Coaches and creators with an audience that asks what they take before training.
  • Nutrition retailers adding an own-brand reference in a high-margin, high-repeat category.
  • Established sports brands completing a range that already has protein and creatine — usually manufactured alongside the rest of our private label sports nutrition catalogue so the whole range shares one manufacturer and one set of documentation.

How to start

The order of decisions: positioning → stimulant level (which sets your labelling obligations) → actives → vitamin and mineral package that carries your claims → flavour → format → volume. Note where the vitamins sit in that sequence: not last, as an afterthought, but as the part of the formula that determines what your packaging can say.

"In pre-workout, the ingredients that sell the product cannot be claimed, and the ingredients that can be claimed do not sell it. Designing for both at once is the whole job."

Sources and date checked

The ingredient-by-ingredient claims check in this article was carried out on 17 August 2026 against the table of authorised nutrition and health claims published by AESAN, the Spanish competent authority, which consolidates the claims authorised under Regulation (EC) 1924/2006 and Regulation (EU) 432/2012. The authorised list changes over time: verify against the EU Register of nutrition and health claims before printing labels. Caffeine labelling particulars are set in Annex III of Regulation (EU) 1169/2011 and are deliberately not quoted here.

Frequently asked questions

Can I claim that caffeine improves focus or performance on my pre-workout label?

No. Caffeine does not appear as an authorised health claim in the EU list at all, so there is no compliant wording available for it — and paraphrasing your own version is not an option, because health claims are fixed authorised wording. The same applies to beta-alanine, citrulline, arginine, taurine, carnitine and glutamine. Claims on a pre-workout label are normally built on the B vitamins and magnesium in the formula, which do have authorised claims.

So what can a pre-workout label actually say?

Claims built on the nutrients in the formula that have authorised wording. Niacin, riboflavin, thiamine, vitamin B6, vitamin B12 and magnesium all have authorised claims such as contributing to normal energy-yielding metabolism or to the normal function of the nervous system, and magnesium has one on helping reduce tiredness and fatigue. Each has its own condition of use — typically that the product is at least a source of that nutrient — so the formula has to be designed to meet it.

Does a pre-workout need a warning on the label because of the caffeine?

Additional mandatory particulars apply to high-caffeine beverages and to foods with added caffeine under Annex III of Regulation (EU) 1169/2011, and the threshold and exact wording are set there. Because those values must be read from the current consolidated text rather than quoted second-hand, ask your manufacturer's regulatory team to compute it for your specific serving and format before you print.

Which format is best for a private label pre-workout?

Flavoured powder in a tub is the category default and the cheapest per serving, and it lets the consumer see the volume they are buying. Single-serve sticks are growing fast because they solve dosing, travel well and support a premium price, which matters in a category where the consumer cannot judge the formula. Both are standard formats, so the choice is commercial rather than technical.
