Noobru is a supplement brand that's been growing in popularity. The company's most popular product is a powdered nootropic supplement called Noobru Advantage that's used to "Think Clear" and "Boost Focus."

But does Noobru contain ingredients shown in clinical studies to support optimal cognition, or are these just marketing claims? Does the brand use any questionable additive ingredients? How do real users rate and describe the effects of Noobru? And was Noobru really featured in The Guardian?

In this article we'll answer all of these questions and more, as we analyze the ingredients in Noobru based on clinical studies to give our take on whether or not the supplement is likely to have a nootropic (cognitive enhancing) effect.

We'll feature unsponsored customer reviews of the brand, and share our concerns about some of the health and media claims on the Noobru website.

Ingredient Analysis

The ingredients in Noobru Advantage are shown above.

Some of the active ingredients do have research backing for their nootropic effect.

Choline bitartrate "has shown favorable effects...in terms of improved cognitive function" according to a medical review published in the Frontiers in Endocrinology journal.

N-acetyl tyrosine is a dopamine precursor, and can improve cognitive function during short-term stress (such as an exam setting) according to a 2015 medical review.

Alpha GPC is clinically shown to support cognitive function, as we documented in our Auri Mushroom Gummies reviews article.

Phosphatidylserine is another research-backed nootropic ingredient, and was shown in a 2010 medical review to enhance memory.

Some of the inactive ingredients in this supplement, however, may be questionable from a health perspective.

Erythritol is a naturally-derived sweetener that can increase blood clotting and is associated with increased risk of stroke according to a medical review published in the Nature Medicine journal.

Citric acid is clinically shown to trigger whole-body inflammation in some individuals.

Natural flavors is a broad categorical descriptor that fails to document the specific flavoring agents used, and without this information it's challenging to make a safety assessment.

Overall, we consider Noobru Advantage to be an effectively formulated supplement for nootropic effect, but it's not a product we currently recommend given the inactive ingredients highlighted above.

Real People Try Noobru

A YouTube creator named "RunArnoRun" has a video sharing his experience after taking Noobru Advantage for a full year:

A TikTok creator named Leslie Crudup suggests in the comments that Noobru has been helpful for supporting her focus:

Does Noobru Cause Side Effects?

Noobru doesn't appear to be clinically tested, which makes it challenging to predict the risk of side effects.

However, we can make an educated guess based on its ingredients.

We already discussed the potential risk related to erythritol in the ingredient analysis section.

Alpha GPC increased the risk of stroke by over 40% in people over 50 years old in one medical review, as we documented in our Quantumind reviews article.

Based on these two active ingredients, we consider the risk of side effects to be somewhat higher for Noobru than for the average nootropic supplement that we've reviewed to date on Illuminate Health.

We would advise patients to speak with their doctor about the ingredients in this supplement before taking it.

Questionable Claims on Brand's Website

There are a number of questionable and uncited claims on the Noobru website that we want to call reader attention to.

As shown below, Noobru's website suggests that the supplement was praised in The Guardian:

However, we can't find any evidence that this is the case, and as shown below, a search of the brand's name on The Guardian's website returns no results:

The Noobru website also claims that their formulation delivers a synergy "far more potent" than the sum of the individual effects from the active ingredients:

We don't understand how the brand can make this specific health claim, since this supplement doesn't appear to have been studied in any clinical trials.

There is no citation provided for this claim.

We recommend that consumers be extremely wary when purchasing from brands that make specific and uncited health claims.

Conclusion

Noobru Advantage is the nootropic supplement sold by Noobru.

It's decently formulated from an efficacy perspective, and poorly formulated from a safety perspective in our opinion.

Most of the active ingredients in this supplement contain research backing for cognitive enhancement, but several of the inactive ingredients (and one of the active ingredients -- Alpha GPC) may cause side effects based on our review of clinical studies.

At the time of publishing this article, the Noobru website (linked here for convenience) appears to be the only official retailer of this supplement.

Noobru has a quote from The Guardian on their website, but we can't find any evidence The Guardian actually published a favorable review of Noobru.

Noobru's website also claims that the supplement has a synergistic effect, but there is no evidence provided to support this claim, and we don't understand how the brand can make a specific health claims about ingredient synergy if they didn't fund a clinical trial.

In this article we featured two real user reviews of Noobru, both of which were positive.
