Everyone seems to be talking about how messed up their metabolism is these days. Maybe it’s because so many of us have hit that frustrating plateau where putting in the effort doesn’t seem to match the results.
You tweak your meals and push through workouts, yet progress feels slow. Maybe you need to find something to complement the hard work you’re already putting in. Metabolism-boosting supplements have been doing just that.
People are increasingly using them for that extra edge, something to help their bodies work smarter.
BrickHouse Nutrition LEAN seems to be the most popular one. It’s marketed as a formula designed to support weight management by boosting your metabolism.
Does it work? Does its blend of ingredients stand out? Heck, does it even taste decent? Let’s find the answers to these questions, and see whether it’s worth a spot in your health routine.
Ingredient Analysis
BrickHouse Nutrition LEAN combines a variety of ingredients, aiming to lose and manage their weight, and boost their metabolism. Among these, some stand out due to their solid scientific backing.
The product’s formula includes Caffeine Anhydrous, Chromium, Caralluma fimbriata Stem Extract, Meratrim®, and InnoSlim®, as well as several other components like EGCG, Advantra Z, and Fucoxanthin. Let’s take a closer look at the key ingredients;

Caffeine Anhydrous
Caffeine Anhydrous is a concentrated form of caffeine that’s had water removed, leaving a potent, crystalline powder. It works by blocking the neurotransmitter adenosine, which helps you feel more awake and energized.
Research, including a 2020 study, supports its role in boosting metabolism and enhancing fat burning by increasing thermogenesis (heat production).
There have been quite a few studies that suggest higher blood concentrations of caffeine may be associated with a lower body mass index (BMI) and lower body fat mass. — Allegra Picano
At the same time, caffeine can aid exercise performance and focus, providing an edge for those combining weight-loss efforts with physical activity.
For most adults, moderate caffeine consumption (up to 400 milligrams daily) is generally considered safe. However, exceeding this amount can cause side effects like jitteriness or insomnia. So, you might want to stay within recommended limits[1].
We approve of this ingredient.
Chromium
Chromium is a trace mineral essential for processing carbohydrates, fats, and proteins. According to a 2014 study, it supports the action of insulin, which can help regulate blood sugar and improve insulin sensitivity.
Some studies have shown its potential to reduce sugar cravings, perfect for those tackling hunger and overeating.
While research around chromium's weight-loss benefits is mixed, its role in healthy metabolic function is well-documented.
Optimizing chromium intake through diet or supplements may support blood sugar stability, which is crucial for managing energy and appetite[2].
We approve of this ingredient.
Caralluma fimbriata Stem Extract
This plant extract comes from a cactus plant, and was traditionally consumed to suppress hunger. To this day, it’s still known for its appetite-suppressing claims.
However, the research available is limited and inconsistent. While some studies suggest it may reduce appetite or waist size, there are no long-term and large-scale trials to confirm these effects definitively[3].
Furthermore, potential digestive side effects like bloating and stomach upset may scare away potential users. Until more robust evidence emerges, Caralluma fimbriata cannot be confidently recommended as an effective weight-loss tool.
We don’t approve of this ingredient.
Meratrim®
Meratrim® is a patented blend of Sphaeranthus indicus (a flower) and Garcinia mangostana (mangosteen fruit rind).
It is marketed as a fat-burner purported to reduce fat storage and enhance metabolic activity. While some small studies suggest modest weight-loss results, they are typically funded by industry groups and have methodological limitations, raising concerns about bias[4].
Independent research validating these claims is minimal, and the lack of peer-reviewed large-scale trials makes it hard to endorse Meratrim® as a proven weight-loss ingredient. Without stronger data, it remains speculative at best.
We, therefore, don’t approve of this ingredient.
InnoSlim®
This proprietary blend of ginseng and astragalus claims to support glucose metabolism, reduce fat absorption, and activate AMPK, an enzyme associated with energy regulation[5].
While intriguing, the evidence backing these claims is limited to preliminary studies with unclear applicability to real-world settings.
There’s also little transparency about the blend’s exact composition, which can leave users uncertain about what they’re consuming.
Without independent, large-scale studies to validate its efficacy and safety, the claims surrounding InnoSlim® don’t hold enough weight to earn approval.
We don’t approve of this ingredient.
We tried BrickHouse Nutrition LEAN

We gave BrickHouse Nutrition LEAN a shot, and it felt like an experiment in diligence.
Now, the capsules were easy to incorporate into a morning routine, though remembering to take all three post-breakfast required some consistency. We appreciated this convenience, though.
For mixability, or in this case, ‘swallow-ability’ (if we can call it that), the capsules were straightforward. They went down easily with water and avoided any lingering aftertaste. However, there’s no flavor to assess, so taste is off the equation.
LEAN seemed to provide a steady but mild energy uplift. There were no jitters, but also no dramatic bursts of vitality.
Appetite control was noticeable, especially in reducing those midday snack cravings. Yet, these changes felt just…moderate. We could observe some progress when paired with light exercise and a mindful diet, but not enough to rave about.
The product is undeniably convenient for busy schedules, though it’s not unique. At least not in a crowded market.
While it could do something for those looking for minor appetite suppression, the results don’t justify a high personal recommendation. It’s decent, but its effectiveness doesn’t outshine its peers in the weight-loss supplement space.
Side Effects & Safety
BrickHouse Nutrition LEAN may cause mild side effects in some users.
Commonly mentioned issues include jitteriness, restlessness, or trouble sleeping, often linked to its caffeine content. Those sensitive to stimulants may need to take extra caution and adjust their dosage or timing to avoid unpleasant effects.
A few users have reported minor digestive discomfort, such as bloating or upset stomach, possibly due to the blend’s active ingredients.
These reactions are typically temporary and tend to subside as the body adjusts.
LEAN is not recommended for individuals under 18, pregnant or nursing women, or those with existing medical conditions without consulting a healthcare provider.
Anyone on medications or managing chronic conditions like high blood pressure should seek professional advice before use.
Real Customer Reviews
Feedback for BrickHouse Nutrition LEAN has been mixed. On Trustpilot, the company holds a commendable rating of 4.5 out of 5 stars.
Some users claim they experienced reduced appetite and improved energy. But, as you’d expect, opinions are varied.
One satisfied customer who left a 4-star rating, shared,
I’m on my second week and have lost 2 pounds. My appetite is reduced later in the day and my energy is up. No side effects. If this keeps up, I’ll be at my goal weight in about 4 months. The only issue is the price. It’s expensive.
On the other hand, not every user has been impressed. A less favorable review from a user who left a 1-star rating, reads,
Lean did not do anything for weight loss besides giving me diarrhea. So not worth the money at any price. So disappointing.
So, reviews for LEAN are mixed, suggesting that results might significantly depend on individual factors like body type, diet, and lifestyle.
Where to Find the Best Value
BrickHouse Nutrition LEAN is primarily available on the official BrickHouse Nutrition website. Here, a single bottle costs $99.95, with discounts offered for bundles and subscriptions.
Compared to similar metabolism-boosting weight loss supplements, LEAN falls on the higher end of the price spectrum. Many competitors offer their products between $40 and $70 per bottle.
The manufacturer argues that LEAN’s ingredient profile might justify the premium pricing. We still think there are better budget-friendly options for those seeking a more comprehensive formula.

Should You Buy BrickHouse Nutrition LEAN?
Customer reviews for BrickHouse Nutrition LEAN are mainly positive, with many users praising its ability to curb hunger and provide sustainable energy.

There are some caveats. LEAN contains caffeine, which could cause jitters or sleeplessness for sensitive individuals.

Consider supplementing LEAN with the powerful botanicals found in KetoFuse, such as African Mango, Raspberry Ketones, and Green Tea Extract.
