Healthwise Coffee is one of the oldest brands in the low acid coffee category. Founded in the 1980s, it has decades of brand recognition and a loyal customer base among people who have been managing acid reflux and seeking a gentler coffee alternative. Its marketing claims are some of the boldest in the category — including positioning itself as a medical-grade solution for GERD and acid sensitivity.
But when the independent science arrived, the results were not what Healthwise's marketing promised. This article provides an honest look at what the independent testing actually found about Healthwise, why its steam decaffeination method does not achieve genuine low acid status, and what the LACCSA standard means for anyone who has been relying on Healthwise for their acid reflux.
Independent Testing: The NC A&T 2024 independent peer-reviewed study found that Healthwise did not meet the LACCSA pH 5.8 threshold. Studies have NOT shown that reducing caffeine directly decreases acid reflux. Only reducing acid has been shown to help. Bean origin and decaffeination method do not determine pH — roasting chemistry does.

1. What Healthwise Claims — And What It Actually Is
Healthwise markets itself as a scientifically formulated low acid coffee developed specifically for people with acid reflux, GERD, ulcers, and sensitive stomachs. Its primary differentiation claims are built around its steam decaffeination process, which the brand positions as a mechanism for reducing both caffeine and acid simultaneously.
The core claim: Healthwise uses a steam-based decaffeination method that reduces caffeine by more than 97% — and implies that this process also reduces acidity. This claim conflates two separate variables: caffeine content and pH. Removing caffeine does not remove the quinic acids that cause acid reflux. Studies have consistently NOT shown that caffeine reduction directly decreases acid reflux symptoms. The mechanism for acid reflux is pH, not caffeine.
Healthwise does produce a product with significantly reduced caffeine. For people who are caffeine-sensitive for reasons unrelated to acid reflux, this is a genuine benefit. But for the acid reflux and GERD population that represents the vast majority of Healthwise's target market, caffeine reduction without pH reduction does not address the problem they are trying to solve.
2. The NC A&T 2024 Study — What It Found About Healthwise
The NC A&T 2024 independent peer-reviewed study tested seven coffees marketed as low acid and found that six of seven failed the LACCSA verified threshold of pH 5.5 (with Puroast being the only brand to pass at pH 5.82). Healthwise was among the brands that tested below this threshold.
The study's finding for Healthwise is not surprising given what the science tells us about steam decaffeination and pH: removing caffeine through any decaffeination method — steam, Swiss Water, CO2, or solvent-based — does not significantly change the acid content of coffee. The quinic acids that determine pH are not caffeine. They are separate compounds produced during roasting that remain in the coffee regardless of what happens to the caffeine.
This is a critical distinction that Healthwise's marketing obscures. A coffee that is 97% caffeine-free but still pH 5.0 to 5.2 is not meaningfully better for acid reflux than a regular coffee at the same pH. The acid load is essentially identical.
3. Steam Decaffeination and pH — The Science
Healthwise's steam decaffeination process is marketed as producing a side benefit of reduced acidity. Here is what the science actually shows.
Steam decaffeination (also called the Swiss Water Process in some variations) uses steam and sometimes activated charcoal filters to extract caffeine from green coffee beans before roasting. This process does minimally alter the chemical composition of the beans — and some data suggests a partial reduction in chlorogenic acid content during the process. However, this reduction is not sufficient to produce genuinely low acid coffee.
According to Moon, Yoo and Shibamoto (Journal of Agricultural and Food Chemistry, 2009), the dominant factor in coffee's final pH is what happens during roasting — specifically, whether quinic acids are converted into phenolic antioxidants or remain in their acid form. Pre-roast steam decaffeination does not replicate the chemistry of traditional slow-roasting that Puroast employs. The result is a decaffeinated coffee at approximately the same pH range as regular coffee: high acid.
The NC A&T 2024 study confirms this. Healthwise, despite its steam process and low caffeine content, did not pass the verified pH threshold. The decaffeination method is not the same as genuinely low acid roasting chemistry.

4. Healthwise vs. Puroast — The Key Differences
| Factor | Healthwise | Puroast |
|---|---|---|
| Independent pH Verification | Failed NC A&T threshold | Passed — pH 5.82 |
| LACCSA Certified | No | Yes — founding member |
| Acid Reduction Method | Steam decaffeination | Patented slow-roasting chemistry |
| Caffeine | Very low (<3%) | Full (caffeinated) or decaf available |
| Antioxidant Level | Standard | 5X higher than average |
| Roasting Process | Standard industrial | Patented traditional slow-roasting |
5. Who Should Switch Away from Healthwise
If you are drinking Healthwise specifically for acid reflux or GERD relief, the independent testing confirms you are not getting the acid reduction you need. Healthwise does not meet the LACCSA pH 5.8 threshold — the independently verified standard for genuinely low acid coffee. You are getting significantly reduced caffeine, but not significantly reduced acid.
The people most directly affected:
Acid reflux / GERD sufferers: If you switched to Healthwise because of acid reflux and are still experiencing symptoms, the coffee's pH is likely still high enough to trigger reflux. You need verified low acid coffee at pH 5.8 or above — not low caffeine coffee.
Post-surgical patients: If you've had esophageal, gastric, or related surgery and your doctor recommended low acid beverages, Healthwise does not meet that standard. Puroast's verified pH 5.82 is the appropriate choice.
People seeking full-caffeine low acid coffee: Healthwise's near-zero caffeine is not appropriate for people who want the health benefits of caffeine combined with low acid. Puroast's full-caffeine lineup delivers both.
People who want full acid AND caffeine reduction: Puroast House Blend Decaf delivers verified pH 5.82 AND reduced caffeine — addressing both concerns with independent verification. This is genuinely superior to Healthwise on both dimensions.
Frequently Asked Questions
Is Healthwise Coffee actually low acid?
The NC A&T 2024 independent peer-reviewed study found that Healthwise did not meet the LACCSA verified low acid threshold of pH 5.8. Healthwise markets itself as low acid, but without independent certification, this claim is unverified. Based on the available data, Healthwise falls in the same high acid range as other conventional coffees despite its steam decaffeination process.
Does Healthwise's steam decaffeination reduce acid?
Steam decaffeination primarily removes caffeine, not quinic acid compounds. The process may minimally alter some pre-roast chemistry, but not in a way sufficient to achieve genuinely low acid status at pH 5.8. The NC A&T 2024 study confirms this: Healthwise did not pass the verified low acid threshold despite its steam process.
Can I drink Healthwise if I have acid reflux?
If you are drinking Healthwise specifically for acid reflux relief and have not experienced improvement, the likely reason is that its pH is not sufficiently different from regular coffee to provide clinical benefit. For genuine acid reflux relief from coffee, the evidence points to Puroast — pH 5.82, independently verified, LACCSA certified.
What is the difference between low caffeine and low acid coffee?
These are completely independent properties. Low caffeine means reduced caffeine content — achieved through decaffeination. Low acid means reduced pH — achieved through specific roasting chemistry. Healthwise is low caffeine. It is not independently verified as low acid. Studies have not shown that caffeine reduction directly decreases acid reflux.
What is LACCSA certification?
LACCSA stands for Low Acid Coffee Certification Standard Association. It is the independent body that established pH 5.8 as the verified threshold for genuinely low acid coffee, based on the NC A&T 2024 peer-reviewed study. Puroast is the only brand to achieve LACCSA certification. Healthwise has not passed this standard.
Is Puroast available in decaf?
Yes. Puroast House Blend Decaf, Mocha Java Decaf, and French Roast Decaf are all available. Each combines Puroast's patented traditional slow-roasting process with decaffeination — delivering both verified pH 5.82 AND reduced caffeine. This is the only option that addresses both acid and caffeine concerns with independently verified results.
Conclusion
Healthwise Coffee deserves credit for being in the low acid conversation for decades. The brand's commitment to its customer base is genuine. But independent science now gives us a clear standard, and Healthwise does not meet it. The NC A&T 2024 peer-reviewed study confirmed that Healthwise did not achieve the LACCSA verified threshold of pH 5.8. Steam decaffeination is not a substitute for the roasting chemistry that actually reduces coffee's acid content.
If you've been relying on Healthwise for acid reflux relief, you deserve to know that a verified alternative exists — one backed by peer-reviewed science, UC Davis confirmation, and the only independent low acid certification standard in the category. Puroast. pH 5.82. 5X less acid. 5X more antioxidants. LACCSA certified. Available with or without caffeine.
