Introduction To Noobru

Noobru is a simple idea - offering the benefits of nootropics in a drink. A nice idea, but does it really work in practice? Before we get started, let's talk about the guy behind Noobru – Martyn Cook. You probably haven't heard of him, but he's a self-proclaimed serial entrepreneur. But when you strip away the self-promotion, what are we left with? A genuine brain elixir, or just a cleverly marketed beverage? As we dive further, we'll sift through the claims, the ingredients, and, of course test the product for ourselves. Because, let's be real: while a catchy sales pitch can be entertaining, it's the substance that truly matters. Let's find out if Noobru and its creator stand up to the scrutiny.

Benefits of Noobru

Claimed Benefits of Noobru

Noobru claim that Noobru Advantage does the following:

  • "Be at your best everyday"
  •  "Sharp focus"
  •  "Clear thinking"
  • "Quick mind"
  • "Happy, relaxed alertness"
  • "Everything the brain needs to unlock its peak performance"

Noobru pitches itself not just as a drink, but as a daily dose of your best self. The grand promise? Transforming ordinary days into ones where you're constantly at your peak. It's a compelling image: every sip seems to guarantee razor-sharp focus, unclouded thinking, and a mind that works faster than a caffeinated squirrel on a treadmill. Beyond the cognitive flair, there's also the allure of a "happy, relaxed alertness", seemingly striking that perfect balance between calm and energy. The origin story is straightforward: the creators wanted this nirvana state for themselves, so they brewed up Noobru, aiming to offer everyone a key to unlock their brain's full potential. While the pitch is tantalizing, the real test is whether the drink can deliver on such lofty claims.

Our Experience With Noobru

After receiving our Noobru order and anticipating its captivating claims of peak daily performance, our team decided it was time for a thorough trial. Our objective was simple: to determine if Noobru could genuinely deliver on its promise of sharp focus, clear thinking, and an invigorating yet relaxed alertness.

Starting with the taste, while Noobru offers strawberry and lemon flavors, the presence of Stevia gave an unmistakable and, to many, an unpleasant artificial aftertaste.

However, taste is subjective. The real concern arises when assessing the drink's efficacy. Despite our earnest trials, we found no discernable effects on our cognitive or mood enhancement, a sentiment echoed by a significant portion of customer reviews.

Examining the ingredient list offers some insights into potential reasons. While L-Theanine, found in many nootropics for its calming properties[1], and Ashwagandha, known for its stress-reducing capabilities[2], are part of the mix, their effectiveness often hinges on dosage. For instance, many studies suggest L-Theanine's optimal dose to be in the range of 100-200 mg[3], and while Noobru™ does seem to meet this threshold, other ingredients fall short.

Sulbutiamine, an enhanced version of Vitamin B1, requires dosages around 400-600 mg for noticeable effects[4]. With Noobru™ containing only 1 mg, this is a glaring underdose. Similarly, Phosphatidyl Serine has research backing its potential in cognitive enhancement, especially in elderly populations[5]. However, its efficacy is often seen at doses of 300 mg[6]. Noobru's formulation contains a mere 50 mg, which might be insufficient to produce any tangible effects.

Furthermore, the blend doesn't seem to consider potential interactions. For instance, Piperine can enhance the bioavailability of several compounds[7], but without detailed studies on its interactions with all Noobru ingredients, it's hard to predict its overall impact.

While Noobru brings together a range of nootropic ingredients, the devil, as always, is in the details. The dosages and potential interactions play a pivotal role in any supplement's efficacy. Based on our experience and a deeper dive into its formulation, Noobru might benefit from revisiting and potentially refining its ingredient list and dosages. As in many scientific pursuits, while individual ingredients can show promise, their amalgamation requires rigorous research and optimization[8].

Research And Evidence

Potentially Misleading Claims

Claim: Sharp focus and clear thinking

  • L-Theanine (200 mg): Found in tea, it is known to promote relaxation without drowsiness and can potentially enhance attention. However, its solo contribution to "sharp focus" and "clear thinking" can be debated, as its effects are more pronounced when combined with caffeine[9].
  • Alpha GPC (120 mg): It might support cognitive function and is sometimes taken to enhance mental focus. However, the optimal dosages for these effects are debated[10].
  • Huperzine A (200 μg): Used for memory enhancement and protection from cognitive decline. Its contribution to daily "focus" is less well-documented[11].

Claim: Quick mind

  • N-Acetyl L-Tyrosine (50 mg): It can potentially improve cognitive performance during stressful situations. Yet, its daily dosage for a "quick mind" isn't established[12].
  • Sulbutiamine (1 mg): It's a synthetic derivative of thiamine believed to improve fatigue. However, its role in promoting a "quick mind" is not well-researched, and the provided dose seems lower than typical dosages[13].

Claim: Happy, relaxed alertness

  • KSM-66® Ashwagandha (100 mg): Ashwagandha has an adaptogenic role and can reduce stress. It may potentially contribute to a "relaxed" state[14]. However, "happy" is subjective and difficult to quantify with any ingredient.
  • L-Theanine (200 mg): As stated, it promotes relaxation but might need to be paired with other ingredients like caffeine for alertness[15].

Claim: Peak performance

  • Most of the ingredients like choline bitartrate, B-vitamins, and others can contribute to overall brain health, but tying them directly to daily "peak performance" is an overreach without comprehensive evidence. For instance, while choline is crucial for cognitive functions, the form presented here (Choline Bitartrate) is less effective in crossing the blood-brain barrier compared to others like CDP-Choline[16].

While some of the ingredients individually might have benefits, their synergistic effects when combined in one drink, like Noobru, are not well-documented. Additionally, the presence of Stevia might affect the palatability for some users due to its saccharine taste. It may be misleading to suggest that the drink, as formulated, can consistently deliver on all the ambitious claims made. More comprehensive and specific studies on the product itself would be needed to validate such assertions.

A Scientific Assessment of Noobru's Ingredients and Dosages

Noobru aims to capitalize on the rapidly expanding nootropic market, but how does it measure up scientifically? Let's delve into the ingredients.

  • Vitamin B1 (1mg): This falls below the clinically-proven amounts required to manifest discernible nootropic benefits. Optimal dosages for cognitive enhancement are considerably higher.
  • Vitamin B5 (as Pantothenic Acid) (30 mg): This vitamin is involved in energy production and the synthesis of coenzyme A[17]. The recommended daily intake is around 5 mg for adults, so the dosage in Noobru is generous[18].
  • Vitamin B6 (as Pyridoxine HCI) (2 mg): Essential for neurotransmitter synthesis, the recommended intake for adults ranges from 1.3 to 2 mg[19]. Noobru's formulation sits comfortably within this range.
  • Choline Bitartrate (250 mg): Choline is vital for cognitive functions, but the bitartrate form is less effective at crossing the blood-brain barrier compared to others like CDP-Choline[20]. Typical dosages for cognitive benefits range from 250 mg to 500 mg, so Noobru's offering is on the lower end[21].
  • L-Theanine (200 mg): Found in tea, L-theanine can promote relaxation and attention, especially when combined with caffeine[22]. This dosage aligns with many studies.
  • Alpha GPC (120 mg): A source of choline that can support cognitive function. However, for noticeable cognitive enhancement, studies have often used doses between 300 mg to 600 mg[23].
  • KSM-66® Ashwagandha (100 mg): Ashwagandha can reduce stress. Studies usually employ 300-500 mg of the root extract for noticeable effects[24].
  • N-Acetyl L-Tyrosine (50 mg): It might improve performance during stress, but studies often use a dosage of 500 mg to 2g[25].
  • Phosphatidyl Serine 20% (50 mg): It's been shown to enhance cognitive function, especially in the elderly. Clinical doses range from 100 mg to 400 mg[26].
  • Sulbutiamine (1 mg): A derivative of thiamine, typical doses range from 200 mg to 600 mg. Noobru's offering seems exceptionally low[27].
  • Huperzine A (200 μg): Known to inhibit acetylcholinesterase, it can support memory, but its long-term safety remains under-researched[28].

Several other ingredients, like taurine and citric acid, provide more general health or flavor benefits rather than direct cognitive enhancements.

Interestingly, there's an absence of certain staples in the nootropic community such as caffeine or bacopa monnieri. These have established bodies of research showcasing their cognitive benefits.

Lastly, the taste. Stevia, a natural sweetener, can sometimes leave an aftertaste reminiscent of saccharine, which some individuals might find off-putting.

While Noobru incorporates several ingredients with nootropic potential, the dosages of several key ingredients fall short of clinically studied amounts. This, combined with the absence of several established nootropics, may leave consumers underwhelmed. We should however give Noobru credit for being transparent in its formulation.

  4. Mild Nausea:
    • Cause: KSM-66® Ashwagandha[34]. While the adaptogenic herb is generally well-tolerated, it may cause stomach upset in some individuals.
  5. Potential Hypertension (High Blood Pressure):
    • Cause: Huperzine A[35]. This compound might lead to elevated blood pressure in certain cases.
  6. Nerve Damage at High Levels:
    • Cause: Excessive Vitamin B6[36]. While the Noobru™ dose seems safe, consistent overconsumption might pose risks.
  7. Aftertaste or Taste Sensitivity:
    • Cause: Stevia[37]. The natural sweetener can leave a lingering taste that some find off-putting.
  8. Potential Diarrhea:
    • Cause: Erythritol[38]. Some sugar alcohols can cause digestive issues, especially if consumed in large amounts.

Best Alternative to Noobru

For a tried and trusted brain booster, NooCube is our current go-to nootropic. Its use of tried and tested nootropic ingredients at clinically proven dosages quite simply works.

Noobru Alternative


4.9 / 5

NooCube is our top recommended nootropic and could be a smarter choice when compared to Noobru. Here's why:

  1. Better Ingredients: NooCube has Bacopa Monnieri, a well-known brain booster. Studies show it helps improve memory and thinking. Noobru doesn’t have this power-player.
  2. Clear Dosages: NooCube tells you exactly how much of each ingredient is inside, ensuring you know what you're taking.
  3. Capsules Over Drinks: NooCube comes in a capsule format. This means it's easier to take, store, and has a longer shelf-life compared to Noobru's drink format.
  4. Trusted by Many: NooCube has been around for a long time and is trusted by many users. Noobru is recently launched and has more negative reviews than we like to see - both around the product experience and customer service.
  5. No Artificial Taste: Unlike Noobru, which some say has an off-putting taste due to Stevia, NooCube capsules don't leave a weird aftertaste.


Our assessment of Noobru has underscored several concerns. Firstly, there's the issue of underdosing of certain crucial ingredients, hampering their effectiveness[39]. Moreover, the taste, often a secondary consideration, has been marred by the use of Stevia, leading to an off-putting saccharine taste for many.

On the broader scale, the company's approach raises eyebrows. Claims, no matter how attractive, should be backed by empirical evidence and transparent information. Unfortunately, Noobru falls short in this regard, with elusive dosage details and exaggerated cognitive enhancement assertions.

Contrastingly, NooCube is our recommended alternative. It's a more traditional capsule nootropic, rather than a drink - but more importantly unlike Noobru it works really well to enhance cognitive performance. Its formulation boasts ingredients like LuteMax 2020, Bacopa Monnieri, and Pterostilbene[40], all dosed transparently and backed by scientific literature[41]. Furthermore, NooCube's inclusion of Alpha GPC4, a renowned cholinergic compound, and a combination of vitamins, demonstrates an understanding of holistic cognitive support.

The world of nootropics is vast, and it's essential to ensure what we consume is both safe and effective. Given the data, NooCube stands out as a more trustworthy option, grounding its claims in science and ensuring user clarity[42] Stay informed, choose wisely, and remember that the brain, our most complex organ, deserves only the best.


Do nootropics work?

Many nootropic ingredients and formulations have been shown to improve attention, memory, and learning, while others may promote relaxation and reduce stress and anxiety. For example, caffeine is a commonly used nootropic that can increase alertness and reduce fatigue, while L-Theanine, an amino acid found in tea leaves, has been shown to promote relaxation and reduce stress.

Are nootropics safe?

Nootropics that contain natural ingredients and have undergone clinical testing are generally considered safe when used properly. It is important to follow recommended dosages and to avoid taking more than the recommended amount. It's also worth being aware of any potential side effects and if necessary consult with your doctor if you have any underlying medical conditions.

What should I expect from a nootropic?

When taking a nootropic supplement, you should expect to experience some improvement in cognitive function, such as enhanced memory, concentration, and mental clarity. The effects of a nootropic will vary depending on the specific ingredients and dosage of the supplement, as well as individual factors such as age, overall health, and your lifestyle.

Which nootropic should I buy?

Popular nootropic supplements include NooCube, Mind Lab Pro, and Vyvamind. NooCube contains a blend of ingredients that may improve memory, focus, and overall cognitive function. Mind Lab Pro is designed to support brain health and cognitive performance through a variety of ingredients, including vitamins, minerals, and plant-based compounds. Vyvamind is a premium nootropic supplement that focuses almost exlcusively on cognitive function and mental performance.
