NAKED Cherry Lime Energy Pre-Workout Review: The Label, the Doses, and the Research

"Clean" pre-workout is a marketing category, and it deserves the same scrutiny as any other. A short label is not automatically a good label. What matters is whether the doses that are printed on it are the doses that were studied, and whether the front of the tub matches the back. NAKED Cherry Lime Energy is a useful product to test that on, because it publishes every amount, lists only about ten active ingredients, and leans hard on the idea that it has nothing to hide.

This article covers what the supplement panel says, how each dose compares with the research, what the product costs per serving, and where the listing contradicts itself.

What You Are Buying

The details below come from the Amazon listing for NAKED Cherry Lime Energy, including the supplement panel shown in the listing's product images. The panel is an image on this listing and not text, so we read the amounts from the image. Check the tub you receive against this summary, since formulas change between production runs.

The listing is also inconsistent about a few of the vitamin numbers. The feature bullets give niacin as 39 mg, vitamin B6 as 600 mcg, and calcium as 27 mcg, while the panel image shows 40 mg, 1 mg, and 30 mg. We used the panel, because a panel is a regulated label and a bullet is ad copy. The differences are small and do not change any conclusion, but they are a reminder that the listing text was not proofread closely.

The Serving-Size Catch: Two Scoops or One

This is the detail most buyers will miss. The panel's serving size is 16 g, and the panel states that this is "about 2 scoops." Every amount in the table above is for that full 16 g serving. But the directions on the listing say to mix 1 to 2 level scoops. If you take a single scoop, you are taking roughly half of everything: about 100 mg of caffeine, 1 g of beta-alanine, 0.5 g of creatine, 0.5 g of arginine, and about 3 g of added sugar. That assumes the two scoops are equal in size and the powder is evenly mixed, which is our arithmetic and not something the manufacturer states.

The 480 g net weight checks out against the label: 30 servings of 16 g is exactly 480 g. It also means each scoop holds roughly 8 g of powder. That is a lot of powder for a product whose active ingredients add up to about 4.2 g plus the vitamins. The rest is mostly cane sugar, which we come to next. It also changes how you should read cost. The $1.50 per serving is for two scoops. If you only use one scoop, you are paying $0.75 per dose, but you are also taking a half dose of a product whose full doses are already modest. We use the full 16 g serving as the basis for every comparison below, because that is what the label says a serving is.

The Sweetener Claim vs. the Panel

The listing title reads, in part, "No Added Sweeteners, Colors Or Flavors." The supplement panel shows 6 g of total sugars and 6 g of added sugars per serving, representing 12 percent of the daily value, and the other-ingredients line leads with cane sugar. It also lists fermented Reb-M, which is a stevia-derived sweetener, and monk fruit extract. The image elsewhere in the listing is more careful and says "No Artificial Colors or Flavors," which is accurate. The vegetable juice is a color, and the "natural plant based flavors" are flavors, so "no added colors or flavors" in the title is also loose.

We are not saying 6 g of sugar is a problem. It is about one and a half teaspoons, it contributes under 30 of the 45 calories, and for a lifter eating a normal diet it is trivial. The point is that "no added sweeteners" is a plainly false description of a product that contains added sugar, Reb-M, and monk fruit, and it appears in the listing title, where it carries the most weight. If a company misdescribes something that is checkable in five seconds on its own label, that is worth knowing when you decide how much weight to give its other claims. The practical consequence is for people who track sugar or who bought the product specifically to avoid sweeteners. It is not stim-free, sweetener-free, or sugar-free. It is a lightly sweetened, low-calorie powder.

Caffeine: 200 mg Against the Research

The caffeine dose is the part of this label that clearly lines up with the research. The International Society of Sports Nutrition position stand on caffeine (Guest and colleagues, 2021) concluded that caffeine consistently improves exercise performance at 3 to 6 mg per kilogram of body mass, that the minimal effective dose may be as low as 2 mg/kg, and that about 9 mg/kg causes a high incidence of side effects without being needed for benefit. An umbrella review of 21 meta-analyses by Grgic and colleagues (2020) found caffeine ergogenic for aerobic endurance, muscle strength, muscle endurance, power, jumping, and exercise speed, with a generally larger effect on aerobic than anaerobic work and most underlying trials in young men.

Run the numbers on 200 mg. For a 65 kg lifter it is about 3.1 mg/kg. For an 80 kg lifter it is 2.5 mg/kg, and for a 100 kg lifter it is 2 mg/kg. So a full two-scoop serving is in the studied range for lighter lifters and at the low end for heavier ones, and a single scoop (about 100 mg) would fall below the 2 mg/kg threshold for anyone over about 50 kg. That is a feature if you want a gentle boost and a bug if you want the full ergogenic dose. The label says the caffeine comes from green coffee beans, and the front of the listing says "unroasted coffee beans" and "organic." Those are sourcing claims. Caffeine is the same molecule whatever the source, and the research on performance is on caffeine, not on its origin.

Where the label is helpful is the safety framing. The listing says no more than one serving every four hours and no more than two servings in 24 hours. Two servings would be 400 mg of caffeine from this product alone. The Wikoff and colleagues (2017) systematic review used 400 mg per day as the adult comparator for healthy adults, so the label's own maximum puts you at that ceiling before any coffee, tea, or soda. Our practical read is that one serving per day is the sensible use, and two servings is a limit that leaves no room for anything else. The Jagim and colleagues (2019) survey of 872 regular pre-workout users found that 54 percent reported side effects, that 14 percent took two or more servings at a time, and that 18 percent took the product more than once per day, which is the pattern to avoid. See our caffeine guide for timing, tolerance, and genetics.

Beta-Alanine: 2 g Is a Starter Dose

Beta-alanine is listed at 2 g of the branded CarnoSyn form per full serving. CarnoSyn is a trademarked beta-alanine, and the molecule is the same one studied in the literature. What matters is the amount and the schedule. The ISSN position stand on beta-alanine (Trexler and colleagues, 2015) concluded that four weeks of supplementation at 4 to 6 g daily significantly raises muscle carnosine, that daily supplementation at that level for at least 2 to 4 weeks improves exercise performance, with more pronounced effects in tasks lasting 1 to 4 minutes, and that the only reported side effect is paresthesia, which can be reduced with divided lower doses of 1.6 g or a sustained-release form.

Two grams per serving is under the 4 to 6 g daily range, and it is a single dose, so you will likely feel tingling from it. For a lifter who trains four days per week and uses one serving on training days only, the average works out to about 1.1 g per day over the week by our arithmetic, a fraction of the studied intake. If you use a single scoop, it is about half of that. That does not mean the product does nothing, because the research is dose-and-time dependent and 2 g on training days will raise carnosine more slowly. It means you should not expect the full buffering effect that the studies describe. The effect size is small to begin with: Saunders and colleagues (2017) pooled 40 studies and 1,461 participants and found an overall effect size of 0.18 (95 percent CI 0.08 to 0.28), and they found that exercise duration moderated the effect, with the strongest signal for efforts lasting 30 seconds to 10 minutes. Our beta-alanine guide covers the loading protocol in depth.

Creatine 1 g and Arginine 1 g

Creatine

The classic loading study by Hultman and colleagues (1996), in 31 men, found that muscle total creatine rose about 20 percent after 6 days at 20 g per day, that 2 g per day maintained the level, and that 3 g per day produced a similar 20 percent rise over 28 days. One gram per serving is below every dose in that study. It will not hurt you, and it is not nothing, since daily creatine intake counts toward your total. But it is a trace amount compared with the 3 to 5 g that people take in studies, so we would not count it as a creatine supplement. If you want the benefits of creatine, you need a separate product. Our creatine guide explains why, and a plain monohydrate powder costs a few cents per gram.

Arginine

The 1 g of arginine is the least defensible ingredient on the label. The case for oral arginine as a pump or performance ingredient is weak even at higher doses. A systematic review of arginine as an ergogenic aid by Alvares and colleagues (2011) found only five acute studies, three of which reported improvement, and eight chronic studies, four of which reported improvement, and concluded it was premature to recommend arginine supplements as an ergogenic aid for healthy active people. A placebo-controlled crossover trial by Meirelles and Matsuura (2018), in 12 trained men, gave 6 g of arginine 60 minutes before a strength test and found no effect on repetitions and no change in plasma nitrite. That is six times the dose in this serving.

The mechanism problem is that oral arginine is largely cleared before it reaches the circulation. Schwedhelm and colleagues (2008) described oral arginine as hampered by extensive presystemic elimination due to intestinal arginase activity, and found that citrulline raised plasma arginine more effectively than arginine itself. Studies that did find a blood pressure effect used much more: a meta-analysis by Dong and colleagues (2011) of 11 trials covered doses of 4 to 24 g per day, and a dose-response analysis by Shiraseb and colleagues (2022) found the effective dose for systolic pressure was at least 4 g per day. A gram of arginine is below those figures by a factor of four or more. See the arginine discussion in our supplements blacklist, and the citrulline guide for the better-supported alternative. The honest description of this ingredient is label dressing: it lets the product list an ingredient that sounds like a pump ingredient without using a dose that would do anything.

The Vitamins

The panel includes vitamin C at 370 percent of the daily value, niacin at 250 percent, vitamin B6 at 40 percent, folate at 83 percent, and vitamin B12 at 1958 percent. The listing frames these as supporting normal energy metabolism and antioxidant support. The B vitamins do play roles in energy metabolism in the body, but that is not the same as acting as an energy supplement for someone who is not deficient. We did not find a performance trial of this vitamin combination at these doses to cite, so we treat them as harmless filler at best.

One practical note: the niacin is listed as nicotinic acid, a form some people notice as skin flushing at higher intakes. Combined with the tingling from beta-alanine, a first-time user could experience two different skin sensations from one scoop and have trouble telling which is which. That is a usability point, not a safety finding. A 47 mcg dose of B12 is extremely high relative to the daily value, but B12 is water-soluble and the percentage is a function of a small daily-value denominator, so it is not a concern on its own.

What It Costs Per Serving

At $44.99 for 30 servings, the tub costs about $1.50 per full serving, or about $0.75 per scoop.

The comparison that matters is what you get for that $1.50. The only active ingredient with strong evidence at the dose in the tub is the caffeine. The beta-alanine, creatine, and arginine are all present at doses below those used in the research, and the vitamins have no performance case. Of each 16 g serving, only about 4.6 g is accounted for by the listed actives (4.2 g) and vitamins (a bit under half a gram), by our arithmetic from the panel. The other 11 g or so is carrier, sugar, sweeteners, acid, and flavoring, and the panel shows 6 g of that is sugar. The label does not break out the rest. In plain terms, you are paying about $1.50 for 200 mg of caffeine, a starter dose of beta-alanine, and a flavored sugar base.

We have not fetched prices for other pre-workouts or for plain caffeine for this review, so we are not going to state a comparison with them. Our pre-workout roundup compares products on a common cost-per-serving basis, and our ingredient evidence ranking explains which ingredients are worth paying for at all.

Safety and Who Should Not Use It

The listing's own safety text is more conservative than most. It says the product is for healthy individuals only, not for anyone who is pregnant or nursing, not for anyone under 18, and not for anyone with a medical condition or taking prescription medication. It also says not to consume it with other stimulants and to assess tolerance with one scoop before increasing. That last instruction is consistent with the serving-size catch above: the manufacturer's own advice is to start with one scoop, which delivers about half the label doses.

The main safety considerations are the usual ones for a stimulant. Caffeine can raise heart rate, cause jitters and anxiety, and interfere with sleep, and 200 mg taken in the evening can still be active at bedtime. Beta-alanine causes tingling. The arginine dose is far too small to raise safety questions on its own, though arginine in general can lower blood pressure at higher doses, as the meta-analyses above show. The sugar and vitamins are not a concern at these levels.

Quality and Third-Party Testing

This is where NAKED's listing is stronger than many competitors. The title and bullets say the product is NSF Certified and verified for purity and safety, and the product images show an NSF "Contents Certified" mark. That is a product-level claim, which is different from a facility claim, and it is a real point in the product's favor if it is accurate. We did not look the product up in NSF's public database for this review, so we are reporting what the listing says, not confirming it. The mark shown reads "Contents Certified," which is a different wording from the NSF Certified for Sport program that athletes in tested sports typically rely on. If you compete in a tested sport, confirm the exact certification and the lot on NSF's site, and ask the company for a certificate of analysis.

Independent testing is a good reason to pick a product with a modest formula. It does not change the dosing analysis above, and it does not make the listing's sweetener description accurate.

Who Should Buy It and Who Should Skip It

It makes sense if you want a moderate-caffeine, low-calorie pre-workout with a short ingredient list and a product-level testing claim, you are comfortable with a flavored, sugar-sweetened powder, and you treat it as a caffeine product with some extras. A lighter lifter using one full serving is in the studied caffeine range, and the safety instructions on the label are conservative.

Skip it if you want the effective doses of beta-alanine, creatine, or arginine from a pre-workout, you want a sweetener-free or sugar-free product, you are caffeine-sensitive, or you want the cheapest way to get 200 mg of caffeine. For most of those goals, the useful ingredients are cheaper bought separately. If your main goal is the pump, our citrulline malate guide explains an ingredient with better evidence than arginine, and none is in this tub.

How HonestLifter Is Reviewing This Product

This is a research review built on the manufacturer's listing and the published studies. HonestLifter's plan for each product is a written review first, then dated checkpoint updates at 30, 60, 90 days, 6 months, and 12 months, backed by our own notes and data and added to this page as they are written. You can read more in our longitudinal review program article.

The Bottom Line

NAKED Cherry Lime Energy is a modest, fairly honest label with one misleading headline. The 200 mg of caffeine is a legitimate dose for most adults. The 2 g of beta-alanine, 1 g of creatine, and 1 g of arginine are all below the amounts used in the research, so they are better thought of as trace additions than as functional doses, and the arginine in particular is a weak ingredient even at higher doses. The two-scoop serving size means a single scoop is a half dose. The listing says "no added sweeteners" over a panel that shows 6 g of added sugar. At $1.50 per full serving, you are mostly paying for caffeine, a flavored base, and the NSF mark if it checks out.

Buy it for the caffeine, the testing claim, and the lack of a proprietary blend. Do not buy it expecting the effective doses of beta-alanine, creatine, or arginine. Check the lot-level testing if you compete in tested sport, talk to your doctor if you take medication, and watch this page for our dated checkpoint updates.
