If you experience burning in your chest after meals, an uncomfortable sour stomach, or painful fullness that lingers for hours, ordinary chalky antacid tablets often fall short. Most traditional antacids merely neutralize acid temporarily without addressing the root cause: heavy, undigested food sitting in your stomach and pushing upward against your lower esophageal sphincter.
NOW Acid Relief with Enzymes provides an innovative two-in-one approach to occasional acid indigestion. Each natural berry-mint chewable tablet pairs fast-acting calcium carbonate from Aquamin® TG sea minerals with a targeted blend of vegetarian digestive enzymes (amylase, protease, lipase, and cellulase). While the porous marine minerals buffer excess stomach acidity within minutes, the enzymes actively break down fats, proteins, and carbohydrates so your meal empties smoothly from your stomach, preventing uncomfortable post-meal pressure.
✓ Rapid Acid Buffering Delivers 560 mg of bioavailable calcium carbonate from mineral-rich marine algae to neutralize excess acid without causing rebound spikes. ✓ Plant-Derived Enzymes Enzyme blend breaks down dietary proteins, fats, starches, and fiber right in the upper stomach to accelerate digestive comfort. ✓ Tooth-Friendly Xylitol Sweetened with dental-friendly xylitol and natural flavors instead of sucrose or corn syrup that feed gut dysbiosis. ✓ 100% Risk-Free Guarantee Backed by VitaNet®, LLC's 31+ years of experience[cite: 1]. We pay return shipping even on opened bottles[cite: 1].To understand how Acid Relief Chewable Enzymes work, it helps to understand why occasional heartburn happens in the first place. Your stomach produces concentrated hydrochloric acid and pepsin to break down dense food, particularly proteins. Separating your stomach from your esophagus is a muscular ring called the lower esophageal sphincter (LES). The LES acts like a one-way valve, preventing harsh gastric contents from splashing up into the sensitive lining of your throat.
When you eat a large, rich, or fatty meal, your stomach takes much longer to break down the food. This delay—known as delayed gastric emptying—causes food to sit in the stomach, ferment, and produce gas. The resulting buildup of intra-gastric pressure forces the LES valve open, allowing stomach juices to splash upward. That burning sensation is what we call heartburn or acid indigestion.
When people take traditional drugstore chalk tablets (mined rock calcium carbonate), they neutralize all the acid in their stomach. While this provides temporary relief, it completely halts natural protein breakdown. The stomach senses that digestion has stopped and responds by releasing an excessive surge of the hormone gastrin. This causes acid rebound, where the stomach pumps out even more acid a few hours later. NOW Acid Relief solves this dilemma by buffering acid gently while supplying active digestive enzymes that keep food moving forward.
Not all calcium carbonate is the same. The source and physical structure of the mineral determine how quickly it works, how long it buffers acid, and whether it causes digestive discomfort like constipation or bloating.
Standard drugstore antacids use calcium carbonate ground from mined limestone rock. Rock-based calcium has a dense, crystal structure that neutralizes stomach acid abruptly, often creating gas bubbles and sharp rebound spikes.
In contrast, NOW Acid Relief with Enzymes uses Aquamin® TG, a multi-mineral complex harvested sustainably from the calcified red seaweed Lithothamnion grown in pristine North Atlantic waters. Under an electron microscope, Aquamin® reveals an intricate, open honeycomb structure. This porous geometry creates a far greater surface area, allowing it to buffer acid in a controlled, continuous manner rather than a violent spike. Furthermore, it naturally delivers over 70 bioactive trace marine minerals—including magnesium, zinc, and selenium—that nourish the digestive tract.
The primary reason NOW Acid Relief Chewable Enzymes stand out from ordinary antacids is its broad-spectrum vegetarian digestive enzyme matrix. Because stomach acid is partially buffered after taking the chewable, these acid-stable enzymes immediately get to work in the upper stomach, breaking down complex meals before they trigger pressure:
Fungal Protease (1,800 HUT)Derived from Aspergillus oryzae
Splits complex dietary proteins into easily absorbed amino acids and peptides. When acid is buffered, natural pepsin slows down; fungal protease steps in so steak, chicken, and dairy continue digesting without causing heaviness. Fungal Amylase (2,500 DU)Derived from Aspergillus oryzae
Breaks down complex carbohydrates, grains, and starches (like bread, pasta, potatoes, and rice) into simple sugars, preventing starch fermentation and gas buildup in the upper digestive tract. Fungal Lipase (60 FIP)Derived from Candida rugosa
Hydrolyzes dietary fats, oils, and fried foods into free fatty acids and glycerol. Because fats slow down stomach emptying more than any other food group, lipase is crucial for speeding up post-meal digestion. Cellulase (400 CU)Derived from Trichoderma longibrachiatum
Breaks down plant cell walls and rigid dietary cellulose fibers found in salads, raw vegetables, and legumes—fibers that the human body cannot break down on its own without enzyme support.At VitaNet®, LLC, we review the peer-reviewed medical literature to ensure our customers receive clear, evidence-based guidance. The synergy between calcium buffering and enzyme supplementation is well documented in clinical gastroenterology:
Drawing from over three decades of answering customer questions at our retail counter in Hartville, Ohio[cite: 1], here is how to get the most effective relief from NOW Acid Relief with Enzymes:
| Situation / Timing | Suggested Serving | How It Helps |
|---|---|---|
| After a Heavy, Fatty, or Spicy Meal | Chew 1 to 2 tablets thoroughly | Buffers excess stomach acid while enzymes immediately assist in digesting fats, proteins, and starches. |
| At the First Sign of Occasional Heartburn | Chew 1 to 2 tablets as symptoms arise | Provides fast, soothing relief from sour stomach and burning sensation in the chest. |
| Maximum Daily Guidance | Do not exceed 6 tablets daily | Keeps supplemental calcium intake well within safe nutritional guidelines. |
At VitaNet®, our highest priority is your long-term health and safety. While calcium carbonate and food-grade enzymes are widely recognized as safe, certain medical conditions and medications require caution:
Occasional heartburn is very common during the second and third trimesters of pregnancy due to hormonal changes and upward physical pressure from the growing baby. While calcium carbonate is commonly recommended by obstetricians for pregnancy heartburn, always consult your OB-GYN or midwife before introducing digestive enzyme formulas.

Standard drugstore antacids rely solely on mined limestone calcium carbonate to neutralize stomach acid, which can halt digestion and cause acid rebound. NOW Acid Relief combines plant-based calcium from porous Aquamin® sea minerals with a blend of four vegetarian digestive enzymes. This dual action soothes acidity while actively breaking down fats, starches, and proteins so your stomach empties efficiently.
You should always chew these tablets thoroughly before swallowing. Chewing breaks down the tablet matrix, distributes the buffering marine minerals across the food bolus, and mixes the digestive enzymes with saliva so they start working immediately upon entering the stomach.
The best time is during or immediately following a heavy, rich, or spicy meal, or at the first onset of occasional heartburn. Because this formula contains active digestive enzymes, it is most beneficial when there is food present in the stomach to digest.
NOW Acid Relief tablets have a pleasant, mild berry-mint flavor. They are sweetened naturally with xylitol, leaving a refreshing taste in your mouth without the chalky, gritty, or artificial aftertaste typical of ordinary limestone antacids.
Calcium carbonate can bind to certain medications, particularly tetracycline and fluoroquinolone antibiotics, as well as levothyroxine thyroid medication. Always separate this chewable supplement by at least 2 to 4 hours from your prescription drugs, and check with your healthcare provider before use.
No. This product contains xylitol, which is completely safe for humans but extremely toxic to dogs and cats. Ingestion of xylitol by pets causes a dangerous release of insulin, resulting in severe hypoglycemia and potential liver failure. Always store this bottle in a secure cabinet out of reach of household animals.
