Millions of people on GLP-1 medications still want their morning coffee. Delayed gastric emptying can make high-acid coffee harder to tolerate — Puroast is independently verified low acid, higher in antioxidants, and USPTO-patented so you can keep the ritual without the harsh cup.
GLP-1 medications slow gastric emptying — useful for appetite and blood sugar, but it also means coffee can sit in the stomach longer.
High-acid coffee on a slower stomach is a common mismatch. Many people cut cups, switch to cold brew workarounds, or quit coffee altogether. Puroast exists for the people who will not give up the ritual — and want a cup backed by independent pH and antioxidant data, not just “low acid” on the label.
Important: Puroast is a coffee — a food product — not a medicine. It does not treat obesity, diabetes, GERD, or GLP-1 side effects. Always follow your clinician’s advice for your medication and diet.
The GLP-1 wave, gut-health retail, and coffee’s unresolved acid problem meet in one place: a verified low-acid cup people can keep.
~18% of U.S. adults
FTI Consulting (spring 2026) estimates ~18% of U.S. adults on a GLP-1 (~47M) — a larger live base than earlier ~20M models. About 40–50% report acid reflux issues; GERD risk cited ~+27% vs non-users (Annals of Internal Medicine, 2025).

#1 ritual
Roughly 30% of coffee drinkers report acid issues — and many “low acid” brands fail independent checks. Coffee is the morning ritual that usually survives when other drinks drop.
Independently verified low acid · ~5× less acid than average commercial coffee · antioxidant-rich roast chemistry · no additives — just coffee and heat.
The daily ritual option for GLP-1 users, GERD-sensitive drinkers, and gut-health-conscious consumers who refuse to quit coffee.
Lead with papers and patents — not adjectives. Here’s why Puroast stands apart.
NC A&T measured Puroast Dark French at pH 5.80 — least acidic of 10 brands tested (nearest competitor 5.38). UC Davis / Shibamoto also reports pH 5.74 vs conventional coffee often ~4.5–5.0.
NC A&T pH study · UC Davis / ShibamotoPeer-reviewed work (incl. Shibamoto / UC Davis) shows the roast pathway yields substantially higher antioxidant activity than coffees tested — and far higher than green tea in the comparison set.
Food Chemistry / JAFC literatureThe only USPTO patent for this low-acid coffee roasting approach. Competitors can market “low acid” — they cannot legally copy this protected process.
U.S. Patent 12,660,842 B2| Coffee type | Typical / reported pH |
|---|---|
| Standard light roast (typical) | ~4.7 |
| Standard dark roast (typical) | ~4.85 |
| Other “low acid” claims (often unverified) | Varies — many fail checks |
| Puroast Dark French (NC A&T) | 5.80 (least acidic of 10 tested) |
| Puroast (UC Davis / Shibamoto) | 5.74 |
NC A&T comparative work has reported that most brands marketed as “low acid” did not hold up under independent testing. Always ask for the lab data.

No. Puroast is coffee. It does not treat nausea, GERD, obesity, or diabetes. Many people choose it because independently measured acidity is lower than typical coffee. Ask your clinician about diet while on medication.
Puroast is a food product and does not interact with medications the way a drug would. Whether coffee fits your plan is a question for your prescriber. We don’t claim to “work with” any brand-name medicine.
NC A&T measured Puroast Dark French at pH 5.80 — least acidic among 10 brands in that comparison. UC Davis / Shibamoto reports pH 5.74 and roughly ~70% lower acidity vs many popular brands. The low-acid roast process is USPTO-patented.
No. The process targets acids associated with harshness; caffeine remains in the normal range for dark-roast-style coffee.
Independent checks have found that many products marketed as low acid do not hold up. Ask for lab pH, peer-reviewed antioxidant work, and whether a patent protects the process — Puroast publishes that stack.
