Naughty Boy EAA 350g - Vegan Fermented Essential Amino Acids & 30 Servings

What is Naughty Boy Amino EAA?

It is a mixable essential amino acid powder with an 11.5 g serving delivering 8.5 g of amino acids and only 10 kcal. The 350 g tub covers exactly 30 servings. The flavours listed: PickNMix, Fizzy Peach Sweets, Ultra Energy, Strawberry Mango and Cherry Mango.

What sets this product apart is the raw material: all nine amino acids come from plant fermentation, which makes the formula entirely vegan. The manufacturer also declares it gluten free, lactose free and with no added sugars.

The rest of the composition fits into four lines: malic acid, natural flavourings, sucralose and a colour that varies with the flavour. One clarification along the way, because the manufacturer's own sheet words it differently: sucralose is an artificial sweetener, not a natural one. The full British brand range sits in our Naughty Boy aisle, and the whole category in EAA.

What does an 11.5 g serving contain?

* Column calculated from the values declared for 11.5 g. No NRV is established for amino acids.

The figure worth remembering, and it is a good one: 8.5 g of amino acids out of 11.5 g of powder, that is 74% of the serving. In other words, only 3 grams go to the flavouring, the malic acid and the sweetener. That is an honest ratio for this category, where some heavily flavoured powders drop a good deal lower.

What is missing, on the other hand, has to be flagged, and it matters: the manufacturer does not publish the amount of each individual amino acid. The ingredients list names them in descending order — leucine, isoleucine, valine, lysine, threonine, phenylalanine, histidine, methionine, tryptophan — but no figure comes with that list. So you cannot know the leucine content, which is the first point of comparison for any EAA. We will not invent it; read the label on the tub you receive.

What the order of the list does tell you is that leucine is the dominant amino acid and that the three BCAAs take the top three places — a classic pattern, consistent with a 2:1:1 ratio across that fraction.

A regulatory note to close: no health claim is authorised in Europe for free amino acids. Not protein synthesis, not recovery, not endurance, not anti-catabolism. We describe a composition, a dose and a use — not an effect.

How do you take Naughty Boy Amino EAA?

Serving: 11.5 g, that is one scoop. Liquid: 400 ml of cold water. Timing: 15 to 30 minutes before the session, during exercise lasting more than 60 minutes, or straight after. Frequency: one serving a day, rest days included according to the manufacturer. Duration: 4 to 12 weeks of use, followed by a 1 to 2 week break.

Four hundred millilitres for 11.5 g is a generous dilution, and it is deliberate. Free amino acids are acidic; at 250 ml the drink becomes hard to finish. Use cold water: warm water dissolves it less well and the taste suffers. Shake until fully dissolved and drink once prepared.

The manufacturer allows for three windows. In practice they are not equally useful depending on your situation: before the session if you train fasted, during beyond an hour of exercise, after if your next meal is a long way off. If you have eaten a full meal two hours before, the extra intake is of little further interest.

The one to two week break after 4 to 12 weeks is a manufacturer recommendation. Nothing compels you to follow it on a product that is only an amino acid supply, but it does have one practical merit: it forces you to check that your diet stands up on its own.

Close the tub properly and store it in a dry place: free amino acid powders take up moisture and cake into a solid block, as the manufacturer points out itself. Stated shelf life: 24 months in the unopened original packaging.

Who is this EAA for, and who is it not for?

It is aimed first and foremost at vegans: the amino acids come from plant fermentation, with no animal raw material. It also suits anyone training fasted or a long way from a meal, and anyone who cannot stomach a milky shaker during exercise — at 10 kcal and with no fat, this drink weighs on nothing.

The manufacturer advises against it for children under 12, and asks pregnant and breastfeeding women as well as people on medication to seek professional advice. Mind the list of traces, which is a long one: the product is made in a facility that handles GLUTEN, MILK, EGGS, SOYA, FISH, CRUSTACEANS, PEANUTS and NUTS. If you are allergic to any of them, the “gluten free” claim made elsewhere is not enough to reassure you. Do not exceed 11.5 g a day.

It suits you less well if you want to compare precisely what you are buying: with no published leucine content, comparison with another EAA remains approximate. That is the real limitation of this product.

What you should not expect from it: 8.5 g of amino acids do not replace a protein intake. This is not a substitute for protein, and the cost per gram is far higher. If your daily intake is already adequate, this product will add nothing measurable — that is the first question to ask yourself, and rarely the one you hear asked in the aisle.

Naughty Boy EAA or Rule One Essential Amino 9?

We sell both, in the same 11.5 g serving size and the same number of servings. The comparison is therefore direct, and it is instructive.

Rule One Essential Amino 9 delivers 7.5 g of amino acids per serving, one gram less, but it publishes the content of each of the nine — 2,500 mg of leucine at the top — and it adds 500 mg of electrolytes. It is the better choice if you want to know exactly what you are drinking, and if the sodium and magnesium intake matters to you on long sessions.

Naughty Boy wins on two concrete points. The amount of amino acids per serving, at 8.5 g against 7.5 g. And the declared plant fermentation, which makes it a genuinely vegan option where not every competitor spells that out. It also offers a wider choice of flavours, in an unashamedly confectionery register.

What settles it, then, is what you value: one extra gram of amino acids, or full transparency on the detail. If your need is mainly mineral hydration, neither will replace a product from the electrolytes aisle. And if you are weighing up a cheaper option, be aware that our BCAA aisle supplies only three amino acids out of nine: the saving is paid for with an incomplete profile.

Frequently asked questions

How much leucine per serving?

The manufacturer does not publish it in the labelling data available to us, and we will not invent it. The ingredients list places leucine first, which indicates it is the dominant one of the nine, with no further precision. The label on the tub you receive is what counts.

Is the formula suitable for vegans?

Yes. The amino acids come from plant fermentation, with no animal raw material, and the manufacturer declares the formula lactose free and gluten free. One caveat, though: the production facility handles milk, eggs and fish, and traces are possible.

How many servings in the 350 g tub?

Thirty exactly, at 11.5 g per serving. At four sessions a week, that works out at around seven weeks; taken daily as the manufacturer suggests, one month. The stated shelf life is 24 months unopened.

Does the Ultra Energy flavour contain caffeine?

The ingredients list supplied to us mentions no stimulant, and no caffeine content has been communicated to us for this flavour. As the name may be misleading, check the label on the tub you receive if you are sensitive to caffeine or if you train in the evening.

Do you really need 400 ml of water?

That is what the manufacturer settles on, and it is a good setting. A free amino acid powder is acidic and concentrated in taste: at 250 ml the drink becomes unpleasant to finish. The generous volume has a second advantage, it makes you drink during the session.

Should you take a break between two periods of use?

The manufacturer advises 4 to 12 weeks of use then a 1 to 2 week break. Nothing requires it on a simple amino acid supply, but that break has one merit: it obliges you to check that your diet stands up on its own.

Can you take it on rest days?

The manufacturer allows it. We are more measured: if your protein intake is already sufficient, taking it on days without a session brings nothing demonstrated and halves how long the tub lasts. Save it for the days when a protein meal is genuinely missing.

Where can you buy Naughty Boy Amino EAA 350 g?

The flavours can be ordered from this page, and we ship throughout France and Europe. The 350 g tub with 30 servings is a sensible size to try for a first EAA.

At the Vendargues shop, about ten minutes from Montpellier, it is one of the few products we put straight up against a competitor on the counter, because the two tubs have exactly the same serving size. One extra gram of amino acids on one side, the full label detail on the other: it is up to the customer to say what matters most. The rest of the amino acids can be compared in our sports nutrition aisle.
