Avanse "LumUltra"

TCE Overall Rating 98.7%

What happens when you take the most potent (legal) memory enhancer – Noopept – and add in a couple of 'clean' stimulants such as Guarana for powerful motivation and mental drive, and a handful of neuro-protectants, and focus boosting plant extracts? The answer is LumUltra - a Noopept based 'super pill' promising to help you develop a smarter, calmer, more focused mind after just 30 days use. But does it work?... Well your emails and reviews seemed to agree with our judging panel who were quick to fall in love with this new 'daily essential'.

Focus Boost

Last Updated: May 15, 2024

Focus Boost

Background Check

Focus Boost is a brain supplement that’s not seen so much popularity in the industry for the few years that it’s been around… and upon first impressions, we sort of understood why. Focus Boost has apparently gone through a few design changes recently, where they completely switched their color scheme from red to green (an odd choice).

Checking out their website, everything about it looked extremely sketchy. Landing on the homepage, you’ll notice that there isn’t actually a lot of information about Focus Boost… not even a short product description. You’re greeted by a couple of stock images put on a slider and an image of Focus Boost’s bottle. Oh, and there’s also a “Shop Now” button.

It truly is a little disappointing though that a supplement that can affect the brain has a “Shop Now” button, but not even the smallest bit of information describing it, what it does, and how it works. Are we supposed to buy without reading more about it first?

Fortunately, the scarcity of any words on Focus Boost’s website also means that sensationalized marketing hype is far and few.

Journeying deeper into the website, while there appear to be tabs for “How it Works” and “Ingredients”, it everything is very vague and the information very shallow, often slightly grazing on a subject without actually going into detail on anything. On the “How it Works” tab, for example, the only piece of information listed is that “Focus Boost is a high quality supplement that promotes energy, focus, memory, and mental acuity” and that “global research on these natural ingredients demonstrate that they bla, bla, bla.” There’s really no information on how it actually works.

Without any detailed information on the mystery that is Focus Boost, we’re at a loss on whether Focus Boost was created by an actual neuroscientist or not.

“Focus Boost is the leading brain supplement designed to boost alertness,
improve memory, and enhance focus.”

Formula Highlights

Supplement Facts:
Vitamin B12 6 mcg
Pantothenic Acid 6 mg
Focus Boost Proprietary Blend 960 mg
Acetyl L-Carnitine, Caffeine Anhydrous, Citicholine,
Bacopa Monnieri, L-Theanine

We have to admit that it was a bit of a hassle looking for Focus Boost’s supplement facts label. While the website talks about Focus Boost’s ingredients, everything is noncommittal and vague… If you want to check the supplement facts out, you’ll find it on Amazon (perhaps due to the stricter regulations they have on supplements sold).

Under first glance, the formula itself looks pretty potent, with only 8 core ingredients being used, including high quality nootropics like Acetyl L-Carnitine, Citicholine (also known as CDP Choline).

We still would love to have seen the ingredients not listed in a proprietary blend, for transparency’s sake. At its current state, it’s very difficult to gauge on the effects of these ingredients (as some nootropics can have different effects under different dosages). We would also like to know how large the dosage of caffeine actually is to prevent overdoing it (generally speaking, the average adult can only take a maximum of 400 mg of caffeine every day).

Aside from this, there isn’t actually a lot to complain about Focus Boost’s formula. While we would have liked a little more transparency, the formula is quite potent, using mostly high quality ingredients (although guarana extract would have been a better choice than caffeine anhydrous).

Key Ingredients:

Bacopa Monniera: An Ayurvedic herb that is believed to help promote clear thinking. Bacopa has a protective role in the brain, aiding the synapses and neurons for better connectivity, while also repairing connections that have been damaged. Bacopa also has antioxidant properties, making it good for preventing age-related brain ailments.

Acetyl L-Carnitine: The “enhanced” version of Carnitine that not only aids in fat burn, but also offers benefits to the brain due to its ability to cross the brain-blood barrier. It aids in the production of acetylcholine, which is a neurotransmitter responsible for improving memory, learning, problem-solving ability, and general cognition.

One thing to note is that while Focus Boost’s formula is potent, there aren’t actually any ingredients that work directly towards improving memory. A suggestion that we could make would probably be the inclusion of Ginkgo Biloba and some form of Ginseng… While that does bump the formula up to having 10 ingredients, it would still be plenty potent.

Effects and Benefits

We gave Focus Boost around the office for everyone to test for 30 days (or at least tried to), but unfortunately, due to some complications, we had to end the test early… but we’ll get to that in a little bit.

Right off the bat, Focus Boost did exactly what it set out to do. Within 10 minutes of popping the first capsule, we could already feel slightly buzzed. Most of us noted on feeling extremely energized and it would be very easy to get our heads down in the office and actually do some productive work. Distractions were pretty much nonexistent, as many of us didn’t even feel the need to go to the bathroom or to the pantry to make a cup of coffee.

This continued for the next couple of weeks. Everyone was super productive and were able to get a lot of work done before they left the office.

The problem with Focus Boost wasn’t so evident in the beginning, but became more so as the test progressed. Mostly, at the end of the day, some felt exhausted and fatigued. At first, we thought this was just due to the fact that we got so much work done, so naturally, we’d be pretty tired. However, we soon realized that this was not the case. This period of fatigue only grew longer and longer as the test went on, and towards the third week, on some days, the mornings after would have us feeling like zombies… unmotivated, and at times, with splitting migraines.

Of course, this only occurred to some of us. A couple did not have these problems at all and they were able to continue to the end of the thirty days. They said that Focus Boost also had positive effects on mood. They felt generally great, stress-free, and always had a fresh start every morning.

We didn’t notice Focus Boost to have any effects on our memory, but going online, some have reported that Focus Boost seemed to work very positively for them in that regard.

Rating: 13/20

Potential Side Effects

While Focus Boost was a success for the most part, there were undoubtedly also some stutters in the duration of our tests. While it was great for focus, we believe that some of us were perhaps just a little too intolerant to the effects of caffeine, which explains the zombie-like mornings and the few headaches here and there. While this doesn’t happen to everyone, some might be more susceptible than others. To be safe, please discontinue taking Focus Boost if any complications arise.

Since Focus Boost also contains caffeine, which can act as a diuretic, your body will lose water faster, and so you should remember to drink plenty of water to prevent dehydration.

Rating: 12/20

Pricing Options

Focus Boost has numerous pricing options, starting from $39.95 for a single 30-capsule bottle, $67.92 for two 30-capsule bottles, and $89.90 for a single 90-capsule bottle. With the recommended daily dosage being 2 capsules, the single bottle should only last you half a month, so the price for a month’s supply should be $67.92.

We’re going to have to warn you though that the SSL Certificate for Focus Boost’s shop has expired already for around half a year now, according to Google, so it may not be such a good idea to order directly from their website. We weren’t able to get to the Shop without going around Google’s protection services, so please keep that in mind for your own safety.

If you would still like to order, a better option would be to go through Amazon as they have better customer protection.

For the price, Focus Boost seems to be of poor value. Its effects are mainly only to Focus, with some minor improvements to mood (although not all of us noticed this). There isn’t actually anything wrong with this… seeing that it does primarily what it says it’s going to do. However, the price just isn’t right. For the amount you’re paying for Focus Boost, there are definitely other options out there that can do the job better, while also being more rounded and affecting memory and mood greatly as well.

Rating: 15/20

Online Reviews

The online reviews on Focus Boost seem a bit mixed, but there are still substantially more positive reviews than negative ones. While some positive reviews do note on Focus Boost also improving on their memory, negative reviews mostly say that Focus Boost is no more effective than just a cup of coffee.

Some have noted that some of Focus Boost’s reviews are fake, though. Try looking for other reviews if all seem very positive.

User Review by Tizzy-Licious on

I got this in exchange for an honest review. I like the easy to swallow gel caps. The color makes it easier to remember to take them daily. Like, “oops where is the red one?” when I look at the handful of supplements I take daily. I only started a few days ago, and I am not real sure it is helping me focus, but I have a lot more energy. Since caffeine is in this in some form, I am thankful to not have the jitters from taking it. Most products with caffeine in them make me really jittery. As far as it making me more focused…. things like this may take time to metabolize in the system and I have really, really bad ADD. So, it could be a while before I notice any real improvements on that part. My energy level is really great and there is no crash stage either.

User Review by Paul on

I decided to do a little investigation myself. To my surprise ! most of the 5 star reviews might be or are possibly fake, because the same people giving 5 stars for this product were also giving 5 stars for Doxiderol. If you think I am making this up, check it yourself. Also, coffee is way better than this product. This is nothing but pure hype. It only took me 2 days to dispose the whole supply because all I felt was nothing, it only kept me awake. No I regret purchasing this product. Remember, check the other 5 star reviewers first.

Rating: 16/20



  • Great as a focus and energy enhancer
  • Potent formula and mostly high-quality ingredients
  • Has a few great ingredients


  • Website lacking any clear information and sources
  • SSL Certificate on website expired for half a year now
  • Little to no effects on memory
  • Not as well rounded as most true nootropics
  • Poor value as just a focus booster at $67.92 for a month’s supply
  • Some side effects are present (mostly caffeine-related)

Our Verdict

At the end of the day, Focus Boost actually excels at what it sets out to do: boost focus. The improvements to focus are actually substantial, and they are more than helpful whenever you need some extra energy to finish a big project, or if as a student, you just have a night to study for an exam.

Beyond this, however, Focus Boost isn’t able to do much else. While there are increases to mood, they are only minor, and during our tests, we did not notice any improvements to memory at all. While the formula is indeed potent, most of the ingredients included only have focus and energy boosting properties. There can be side effects too, if you are intolerant to the effects of caffeine. We can’t say for a fact how much caffeine is in there, but it’s a lot. So please do not try going over the recommended daily dosages, just to be safe from the off chance of negative reactions.

For the price of $67.92, Focus Boost is pretty expensive, considering it doesn’t do much aside from improving your focus states. We recommend that you try out some other nootropics that are better-rounded in effects for a better bang for your buck.


The Best Brain Supplements: Your Complete, Personalized Guide

In such a busy, harried world, people look for all the help they can get.

They’ve got problems remembering things, concentrating in school or focusing on a big work project, or being in the best energy and mood level for family and their personal goals.

Nootropics - also known as “smart pills” and brain enhancement supplements - are designed to help address these cognitive issues and improve memory and learning, focus and concentration, problem solving, and overall energy and vibrancy. These supplements are a potential fit for students (usually college students), professionals and business executives, and the elderly who want to enhance their brain power and performance.

Check the Best Smart Pills

The question, though, is…

Do you know the best brain-enhancing supplement for you?

Our product reviews will answer exactly this. By presenting accurate, up-to-date product information, conducting weeks-long product trial, and raising the alarm on fillers and low-quality ingredients, we’re about to guide you in your decision-making.

We take a long, hard look at the manufacturer, where they manufacture the pill, the website, pricing, customer testimonials, and different authoritative websites that point to how safe and effective a smart pill is.

At the end of it all, we present our Top 5 rated smart pills for your easy reference.

How Do Nootropics Work?

Known by many different names, nootropics act as brain enhancement aids and brain boosters that don’t leave your cognitive wellness to fate.

There are two kinds of nootropics: (1) pharmaceutical cognitive enhancers made up of chemicals believed to have a clear effect on the brain and nervous system, and (2) natural cognitive enhancers, which are mostly herbal or nutrient-based in their composition. Our reviews focus on the second group, which don’t require a prescription, not considered drugs, and thus are allowed to be sold the counter and online via vitamin retail shops like Amazon.

Are natural nootropics actually the savior they’re painted to be?

These plant-based extracts promise improved mental functioning, no less. Their surging popularity, particularly in recent years, can be attributed to their high overall safety value and few and minor side effects compared with their pharmaceutical counterparts.

If you’ve heard of the term “nootropic stack,” it means different herbal or nutrient-based nootropics “stacked” together to achieve your own cognitive targets.

Types of Natural Nootropics

  1. Neurotransmitter enhancers - These increase the activity of brain chemicals responsible for mental sharpness. Examples are acetylcholine, and other neurotransmitters.
  2. Vasodilators - Boost blood flow to the brain via widening the blood vessels.
  3. Antioxidants - Preserve and protect brain cells from the damage caused by free radicals roaming in the body

A high-quality nootropic can change your brain wellness and make you limitless in many different ways. These include enhanced memory, increased attention to detail, outrageously good focus, increased alertness, better mental and visual acuity, improved learning and thinking, managed stress, better mood and energy, and a generally renewed sense of life and brain performance.

This is why this product review guide will help you in so many ways to know a nootropic inside and out. From the ABCs of the product formula to the overall verdict, you will have an informed choice of what to choose for your next nootropic bottle or product.

What Should You Look For In A Top-Rated Nootropic?

  1. Offers essential vitamins and nutrients - Your brain gobbles up an unbelievable amount of vitamins, minerals, amino acids, and nutrients for it to properly function for life’s everyday demands. The nootropic you deserve provides these crucial components and more. Ginkgo biloba, Bacopa monnieri, Panax ginseng, and more - the list is endless, but only a few good ones deserve your attention. Click here for the top-rated ingredient list for a smart pill.

  2. Backed by clinical data and experts - The best nootropics have a solid scientific basis through independent, third-party research data on their effectiveness and benefits.

    There’s no reason for a credible health care expert not to endorse a well-created supplement for brain enhancement.

  3. Superior manufacturing standards - It’s not just about the ingredients, but also creating the product with the highest standards of production. The best supplements are manufactured in the United States, in a laboratory registered by the FDA. The manufacturer should be GMP certified as well!

  4. Independent reviews (Not just Amazon!) - Reviews can be bought and unverified, so keep an eye out for them. Our reviews, for instance, maintain their independence through a circle of product testers that really get to the bottom of things and assess individual product performance and quality.

What Should You Avoid In A Brain Enhancement Supplement?

  1. Improper dosage - Incorrect levels of each active ingredient - yikes! This leads you to believe that you’re getting optimum value and not the cheaper, over-hyped product that it actually is.

  2. Insufficient return policy and fraud - Reputablecompanies offer 100% money-back guarantee since they are confident enough that their product works. Read the fine print and don’t just trust what you see on the surface.

  3. “Free trial” offers - Does it seem too good to be true? Then it probably is. If you have to enter your credit card details to get to try a product for a month for free, then it’s not free.

Let’s combine your due diligence in research and our honest, in-your-face product reviews that won’t leave you guessing and wanting more information.
