Why Trust Our Natural Force Clean Coffee Review? How We Tested

To give you the most authentic and hands-on review possible, I didn’t just read the label. I rigorously tested Natural Force Clean Coffee for 30 consecutive days, brewing it each morning. We evaluated taste and aroma when consumed black, noting its low-acid impact on stomach comfort, especially when compared to a standard store-bought brand. My process was documented with daily tasting notes to track consistency and real-world performance. Here’s a detailed breakdown of our methodology:

  1. Testing Duration & Frequency: I purchased a 12oz bag of Natural Force – Organic Clean Coffee Classic, Mold & Mycotoxin … and drank it exclusively for 30 days. My daily routine involved brewing one to two cups to assess its effects over a meaningful period.
  2. Testing Environment: All testing occurred in my home kitchen, replicating a typical user’s experience. I used filtered water and consistent measurements to ensure a fair evaluation each day.

  3. Specific Scenarios Tested: I evaluated the coffee based on several key factors:

    • Brewing Versatility: I prepared the coffee using three popular methods: a standard drip coffee maker for everyday consistency, a French press to assess its body and richness, and a pour-over cone to analyze its clarity and flavor nuances.
    • Acidity Analysis: This was a critical test. I frequently drank the coffee on an empty stomach to gauge its gentleness. I monitored for any signs of acid reflux, heartburn, or stomach discomfort, which are common complaints with conventional coffee.
    • Flavor Profile Assessment: I tasted the coffee black at various temperatures—hot, warm, and lukewarm—to identify the core flavor notes and check for any bitterness in the aftertaste.
    • Aroma Quality: I evaluated the aroma at three stages: the whole beans upon opening the bag, the freshly ground coffee, and the final brewed cup.
    • Comparison Test: On several occasions, I brewed and tasted it side-by-side with a conventional, non-organic grocery store coffee. This direct comparison made the differences in taste, smoothness, and physical feeling incredibly apparent.
  4. Documentation Methods: I kept a daily journal to log tasting notes, subjective feelings of energy and focus, and crucially, any notes on stomach comfort. This detailed log forms the basis of the specific observations in this review.

What Is Natural Force Clean Coffee? Product Overview & Specifications


Natural Force Clean Coffee is a premium, USDA Organic coffee specifically created for health-conscious consumers. Its main purpose is to provide a cup of coffee that is verifiably free from common contaminants like mold, mycotoxins, pesticides, and heavy metals. This is achieved through rigorous third-party lab testing, a step that goes far beyond standard organic certifications. Made from 100% superior grade Arabica beans, it’s also roasted to be a low-acid coffee, making it significantly gentler on the stomach.

The core problem this coffee solves is the hidden risk of toxins in the conventional coffee supply chain. Many people who experience jitters, brain fog, or stomach upset blame caffeine, but often, mycotoxins—toxic compounds produced by mold—are the real culprits. Natural Force directly addresses this by sourcing high-quality beans and then testing every single batch to ensure purity.

This focus on clean ingredients and verifiable safety makes it a perfect fit for anyone following a clean-eating, Paleo, or keto lifestyle, or simply anyone who wants to start their day with the purest possible product.

Natural Force Clean Coffee Key Features & Real-World Performance

This coffee makes several bold claims, but how do they hold up in the real world? I broke down each key feature based on my month-long testing experience.

The “Clean Coffee” Promise: Is It Genuinely Mold & Mycotoxin-Free?

Natural Force Clean Coffee is genuinely mold and mycotoxin-free due to its rigorous third-party lab testing. The company tests for Ochratoxin A and Aflatoxin, among other contaminants, and provides transparency by making results available online. This ensures a level of purity not guaranteed by standard organic certifications alone.

Mold in coffee is a serious concern. It can grow on beans during the growing, processing, or storage phases, producing mycotoxins that have been linked to a range of health issues. While I can’t run a lab test in my kitchen, I can say that the “feeling” of this coffee is different. During my 30 days of testing, I experienced a clean, sustained energy boost without any of the jitteriness or subsequent crash that I sometimes get from cheaper, conventional coffees. This subjective feeling of “clean energy” strongly supports the brand’s purity claims. The ultimate trust signal, however, is the brand’s transparency. They don’t just say it’s tested; they prove it.

Low Acidity in Practice: Gentle on the Stomach?

This is where Natural Force Clean Coffee truly shines and the benefit I felt most directly. The claim of being a low-acid coffee is not just marketing jargon. To put it to the ultimate test, I made a point of drinking my first cup black on an empty stomach each morning—a habit that with other coffees would often lead to at least some minor discomfort.

Over the entire 30-day testing period, I experienced zero instances of stomach sourness, acid reflux, or digestive irritation. This was a remarkable and consistent result. The coffee has an exceptionally smooth finish, completely lacking the sharp, acidic bite that often characterizes medium roasts. This quality makes it incredibly palatable to drink black, which is a testament to the bean quality and roasting process. If coffee-induced heartburn is your enemy, this coffee is your new best friend.

Flavor Profile & Aroma: How Does the Medium Roast Taste?

While purity is the primary selling point, a coffee still has to taste good. Fortunately, the Natural Force Clean Coffee delivers a very pleasant and satisfying cup.

  • Aroma: As soon as I opened the bag, I was greeted with a fresh, clean aroma with pleasant notes of milk chocolate and toasted nuts. Importantly, it smelled incredibly fresh, with none of the musty or earthy undertones that can sometimes hint at lower-quality or improperly stored beans.
  • Flavor: The taste is best described as balanced, smooth, and classic. It’s a quintessential “coffee” flavor, executed perfectly. The dominant notes I picked up were a mild, nutty sweetness and a clean, non-bitter finish. It’s not an overly complex or bright coffee; its strength lies in its supreme smoothness and drinkability.
  • Verdict on Taste: I consider this a fantastic daily driver. It’s a crowd-pleasing flavor that works perfectly black or with a splash of cream. Coffee aficionados who are searching for exotic, fruity, or highly acidic single-origin notes might find it a bit simple. However, for the 95% of coffee drinkers who just want a delicious, smooth, and reliable cup every morning, the flavor is a major win.

Sourcing & Certifications: What Do USDA Organic & Lab Testing Mean?

The labels on a bag of coffee can be confusing. Here’s what Natural Force’s certifications actually mean for you:

  • USDA Organic: This is a crucial baseline for a “clean” product. This certification guarantees that the coffee beans were grown without the use of synthetic pesticides, herbicides, or fertilizers. It ensures a cleaner bean from the farm level and supports more environmentally friendly agricultural practices.
  • Third-Party Lab Testing: This is the brand’s key differentiator and what truly sets it apart. While “organic” prevents certain chemicals from being added, it doesn’t test for naturally occurring contaminants like mold. Natural Force goes the extra mile by sending every batch of their roasted coffee to an independent lab to test for mycotoxins, heavy metals, and over 150 different pesticides. This provides a verifiable layer of safety that goes far beyond a simple organic certification.
  • Sourcing: The company uses 100% superior-grade, single-origin Arabica beans. High-quality beans grown at high altitudes are naturally denser, more flavorful, and less prone to mold growth in the first place. Starting with a superior raw material is the first step in creating a superior final product.

What Real Users Say: Customer Experiences & Feedback Analysis

User reviews for Natural Force Clean Coffee consistently praise its smooth, non-acidic taste, with many reporting relief from stomach issues common with other coffees. The lab testing for mold and mycotoxins is a frequently cited reason for purchase and loyalty. The most common criticism relates to its premium price point and a flavor profile that some find less bold than competitors.

After analyzing hundreds of verified customer reviews to see if my experience was typical, I found several consistent themes:

  1. Stomach-Friendly & Low-Acid: This is, by far, the most common point of praise. Review after review echoes my experience. Many users state this is the only coffee they can drink without triggering acid reflux or digestive upset. People with GERD and sensitive stomachs repeatedly call it a “game-changer.”
  2. Peace of Mind from Purity: The third-party lab testing is not just a feature; it’s the primary reason many customers become loyal to the brand. Buyers repeatedly mention the value of this transparency, stating it completely justifies the cost for them and provides confidence in the product’s safety.

  3. Smooth, Clean Flavor: The words “smooth,” “clean,” and “non-bitter” appear in the vast majority of positive reviews. Many highlight it as a perfect daily-drinking coffee that doesn’t need sugar or cream to be enjoyable.

  4. The Price Debate: The most frequent, and really only significant, critique is the cost. While most who mention the price feel it’s worth it for the health benefits, it’s undeniably positioned as a premium product. Some users wish they could afford to drink it more often or find the cost a barrier for making it their daily brew.

  5. Flavor Subtlety: A small but vocal minority of users, likely those accustomed to the bright, acidic, and complex profiles of third-wave specialty roasters, describe the flavor as “good but not great” or “a bit one-dimensional.” This aligns perfectly with my finding that the coffee’s strength is its unbeatable purity and smoothness, not its flavor complexity.


✅ What We Loved: Natural Force Clean Coffee Pros

After 30 days of testing, the standout pros of Natural Force Clean Coffee are its verifiable purity and its remarkably gentle nature. The brand’s commitment to transparency combined with a genuinely high-quality product left me deeply impressed.

Transparent, Third-Party Lab Testing for Purity
This is the number one reason to choose this coffee. Natural Force doesn’t just make a “clean coffee” claim; they back it up with evidence. They provide public access to their lab results, verifying the absence of mold, mycotoxins, and hundreds of other toxins. This level of transparency is exceptionally rare and provides ultimate peace of mind.

Genuinely Low-Acid and Stomach-Friendly
In my entire month of testing, I had zero instances of acid reflux or stomach irritation, even on an empty stomach. It is noticeably gentler than any standard coffee I compared it to, making it an ideal choice for anyone with a sensitive stomach. This benefit was immediate and consistent.

Exceptionally Smooth and Clean Flavor Profile
This coffee is completely free of any bitter or sharp acidic notes. This results in a very smooth, round, and easy-to-drink cup that highlights the quality of the beans. It doesn’t require milk or sugar to be palatable, which is a sign of a truly great roast.

USDA Certified Organic
Beyond the mycotoxin testing, the USDA Organic seal guarantees the beans are grown without synthetic pesticides or fertilizers. This contributes to the overall “clean” nature of the product, protects the environment, and ensures a higher quality starting material.

Multiple Roasts and a Swiss Water Process Decaf Available
I love that the brand caters to different preferences. They offer their clean coffee in a Medium Roast, a bolder Dark Roast, and, most impressively, a high-quality, chemical-free Swiss Water Process Decaf. This provides trustworthy options for every type of coffee drinker.

Fresh Aroma and Quality Beans
Upon opening the bag, the aroma is rich, nutty, and undeniably fresh. There is absolutely no hint of the mustiness that can plague lower-quality coffee. A visual inspection of the beans shows they are uniform in size and color, indicating a high-quality, even roast and excellent green coffee sourcing.


❌ What Could Be Better: Natural Force Clean Coffee Cons

No product is perfect, and an honest review requires acknowledging the downsides. While my experience was overwhelmingly positive, there are a few limitations to consider before you buy.

Premium Price Point
There’s no getting around it: this is a premium-priced coffee. The cost is a direct result of high-quality organic sourcing and, most significantly, the expensive third-party lab testing for purity. While the price is justified for those prioritizing health, it can be a barrier for daily drinking on a tight budget.
Context: The price is competitive with other lab-tested, “clean coffee” brands but is significantly higher than standard organic coffee from the grocery store.

Flavor Profile is Clean but Not Complex
I personally found the flavor to be very pleasant, smooth, and balanced. However, it lacks the bright, fruity, or intensely complex notes that a coffee connoisseur might seek in a high-end specialty single-origin bean. Its primary strength is its purity and smoothness, not its unique taste profile.
Who this affects most: This will only be a con for “third-wave” coffee enthusiasts who enjoy exploring coffees with distinct terroir and complex tasting notes. For everyone else, the “simple and smooth” profile is a benefit.

Limited Retail Availability
This coffee is most easily and reliably purchased online, either directly from the Natural Force website or on Amazon. It is not widely available in most grocery stores or local shops. This can be an inconvenience if you run out unexpectedly and need to grab a bag quickly.
Workaround: Both Natural Force and Amazon offer a “Subscribe & Save” model. This is a great solution as it ensures you never run out, and it often comes with a small discount, which helps mitigate the premium price.


Natural Force Clean Coffee vs. Alternatives: How Does It Compare?

The “clean coffee” market is growing. So how does Natural Force stack up against its main competitors? The most common comparison is with brands like Clean Coffee Co., which also market themselves as low-acid and toxin-tested.

Compared to alternatives like Clean Coffee Co., Natural Force offers similar benefits like low acidity and mold testing but stands out with its USDA Organic certification and readily available Swiss Water Process decaf option. While Clean Coffee Co. highlights specific tasting notes like caramel and dark chocolate, Natural Force focuses more on the universally clean, smooth profile and the transparency of its lab testing.

Feature/Aspect Natural Force Clean Coffee Clean Coffee Co. – Low Acid Dark Roast Other “Clean Coffee” Brands (e.g., Purity, Kion)
Key Claim Mold & Mycotoxin Free, Low Acid Tested for Molds and Toxins, Low Acid Mold-Free, High in Antioxidants

Our Rating 4.5/5 ⭐ 4.2/5 ⭐ N/A

Comparison Analysis

  • Natural Force vs. Clean Coffee Co.: Both brands are excellent choices in the low-acid, mold-tested market. The primary advantage for Natural Force is its USDA Organic certification, a standard that the Clean Coffee Co. product does not highlight on its packaging. Clean Coffee Co. focuses its marketing on specific flavor notes like “caramel, dark chocolate,” which may appeal to those looking for a particular taste profile. The choice here comes down to priorities: if certified organic is a must-have for you, Natural Force is the clear winner.
  • Natural Force vs. Other Brands (like Purity/Kion): The broader “clean coffee” space includes other great brands like Purity Coffee or Kion. These brands often emphasize different secondary benefits. For example, Purity Coffee heavily markets its high antioxidant levels (chlorogenic acid) in addition to being mold-free and organic. Natural Force’s marketing is more squarely focused on the “absence of bad” (no mold, no pesticides, low acid) rather than the “presence of extra good” (high antioxidants). This makes Natural Force a straightforward and trustworthy choice for anyone focused primarily on purity and gentleness.


Is Natural Force Clean Coffee Worth the Money? Value Analysis

This is the big question, especially given the premium price tag. After careful consideration and a month of testing, my verdict is clear: Yes, Natural Force Clean Coffee is worth it for the right person.

You aren’t just paying for coffee beans; you are paying for peace of mind. The cost covers not only high-quality, single-origin, USDA Organic beans but also the expensive, batch-by-batch third-party lab analysis. This is a feature that standard organic coffees, even expensive ones, simply do not offer.

Think of it this way: for a similar price, you could buy a bag of very complex, “third-wave” specialty coffee. It might have fascinating flavor notes, but you would have no idea if it contained mycotoxins or pesticide residues. With Natural Force, you sacrifice some of that flavor complexity for a guarantee of purity.

The long-term value proposition is about preventative health. For individuals sensitive to mold, those with compromised immune systems, or anyone looking to minimize their daily toxic load, the slightly higher cost per cup is a worthwhile investment. When you factor in the benefit of avoiding the discomfort of acid reflux and stomach pain, the value becomes even more apparent.

If your primary goal is to drink a verifiably pure, organic, and stomach-friendly coffee, the price is absolutely justified by the rigorous testing and quality it represents. If you are a coffee connoisseur on a tight budget focused solely on exploring complex flavor, you might find better “value” elsewhere, but you will be sacrificing the guaranteed purity.


FAQs: Common Questions About Natural Force Clean Coffee

Is Natural Force coffee truly mold-free?

Yes, Natural Force coffee is verified to be mold-free through rigorous, third-party lab testing on every batch. They test for specific mycotoxins like Aflatoxin and Ochratoxin A to ensure they are well below the strict safety levels set by the European Union. This process goes a significant step beyond standard organic certification to provide proven purity.

What are the benefits of low-acid coffee?

The primary benefit of low-acid coffee is that it’s much gentler on the digestive system. It can significantly reduce the risk of acid reflux, heartburn, and stomach irritation that are often associated with coffee. This makes it an ideal choice for individuals with sensitive stomachs, GERD, or other digestive issues, allowing them to enjoy coffee without the uncomfortable side effects.

Is the Decaf version Swiss Water Processed?

Yes, the Natural Force – Organic Clean Decaf Coffee is decaffeinated using the patented Swiss Water Process. This method is 100% chemical-free, using only water, temperature, and time to gently remove 99.9% of the caffeine. This ensures the decaf coffee remains just as pure and clean as the caffeinated versions, free from residual solvents used in other methods.

What makes a coffee “clean”?

“Clean” coffee typically refers to beans that are certified and tested to be free from common contaminants like mold, mycotoxins, pesticides, and herbicides. This is achieved through a combination of using high-quality organic beans, careful processing and storage, and—most importantly—verifying the final product’s purity with transparent third-party lab testing.

Is Natural Force Clean Coffee worth the price?

Natural Force Clean Coffee is worth the price for individuals who prioritize health, purity, and digestive comfort. The cost covers USDA Organic certification and, crucially, expensive third-party lab testing for mold and mycotoxins. If you have a sensitive stomach or want verifiable proof of your coffee’s purity, the premium investment is justified for that peace of mind.

How does Natural Force compare to Bulletproof coffee?

Natural Force and Bulletproof are both pioneers in the “clean coffee” space, and both test for mycotoxins. The key difference is that Natural Force is USDA Organic certified, a standard that Bulletproof coffee does not carry. Additionally, Bulletproof’s brand is tightly integrated with the ketogenic diet and its specific “butter coffee” recipe, whereas Natural Force has a broader appeal for anyone seeking clean, healthy pantry staples.

What is the optimal way to brew Natural Force coffee?

The optimal way to brew Natural Force coffee depends on your personal taste preference. During my testing, I found:
* A pour-over method produced the cleanest, clearest cup that highlighted its smoothness.
* A French press created a richer, fuller-bodied experience that was still incredibly smooth.
* A standard drip coffee maker produced a consistently good and balanced cup perfect for daily drinking.


Final Verdict: Should You Buy Natural Force Clean Coffee? Who It’s Perfect For

After a month of rigorous testing, my final verdict is simple. If you are looking for a coffee that prioritizes health and purity above all else, buying Natural Force Clean Coffee is an excellent decision.

Perfect for you if…
* ✅ You have a sensitive stomach or experience acid reflux from regular coffee.
* ✅ You are concerned about contaminants like mold and mycotoxins and want verifiable proof of purity.
* ✅ You follow a clean-eating, paleo, or generally health-focused lifestyle.
* ✅ You value smoothness and low bitterness over a complex, acidic flavor profile.

Also Great For…
This coffee is a fantastic choice for anyone looking to “clean up” their diet and reduce their overall toxic load. If you’re just beginning to explore the world of healthy living, starting your day with a verifiably clean cup of coffee is an easy and impactful first step.

Not the Best Choice If…
* ❌ Your primary decision factor is price. There are cheaper organic coffees available (though they lack the crucial lab testing).
* ❌ You are a coffee connoisseur who exclusively seeks out unique, bright, and complex flavor notes from exotic single origins.
* ❌ You prefer the convenience of grabbing a bag from your local grocery store.

If you want to enjoy your daily coffee ritual with the full confidence that it’s helping, not hurting, your health goals, then Natural Force Clean Coffee earns our highest recommendation. For its target audience, it is undeniably one of the best and most trustworthy clean coffees on the market.
