About Sodium Alginate

Sodium alginate, a natural substance derived from seaweed, has become an increasingly popular ingredient in products aimed at managing gastroesophageal reflux disease (GERD) and heartburn. The unique properties of sodium alginate make it especially effective for relieving these common digestive issues.

How Sodium Alginate Works

When ingested, sodium alginate reacts with stomach acid to form a gel-like raft that floats on top of the stomach contents. This raft acts as a barrier, preventing acid from rising back up into the esophagus, which is the cause of heartburn and other reflux-related discomfort.

Watch the demonstration to see how ØBEX forms this natural protective barrier in real-time.

Why Sodium Alginate is Beneficial

Rapid Relief

Sodium alginate works quickly to form a protective barrier, often providing immediate relief from heartburn.

Natural and Safe

As a natural extract from seaweed, sodium alginate is generally well-tolerated and considered safe for most people, including pregnant women.

Non-Systemic Action

Unlike proton pump inhibitors or other acid-suppressing medications, sodium alginate does not affect the overall acidity of the stomach.

Complementary to Other Treatments

Sodium alginate can be used alongside other treatments for GERD or heartburn.

👶 Safe for Pregnancy

Natural alginate therapy is considered safe during pregnancy when other heartburn medications may not be recommended. Enjoy your favorite foods without worry.

I had some spicy burps after eating Thai food. I took a packet, and it worked! The burps got better right away and stopped after 15-20 minutes. Highly recommend!

My husband suffers with GERD and with a recent flare up he was finding minimal relief with over the counter medication. Through a co-worker we were introduced to Obex. As stated it creates a barrier to protect the esophagus. Accompanied by Nexum he was able to finally manage his symptoms. It has played a pivotal role and now has become a part of his regular nighttime routine to ensure protection throughout the night. The fact that this product is all natural and can be taken alone or alongside other medications with no interactions is truly remarkable. It is an added bonus that this product comes in a variety of carefully crafted flavours that don't taste medicinal and are true to the flavour description. Our household will never be without Obex.

Frequently Asked Questions

OBEX uses medical-grade sodium alginate derived from seaweed. When you take it after a meal, it reacts with your stomach acid to form a protective gel-like "raft" that floats on top of your stomach contents. This physical barrier prevents acid from rising into your esophagus, providing relief in as little as 5-10 minutes.

No artificial colors, no artificial preservatives, no complicated chemicals—just effective, natural heartburn relief.

Yes, OBEX is considered safe during pregnancy. Unlike PPIs and many other heartburn medications, alginate therapy works as a physical barrier without being absorbed into your bloodstream. Many pregnant women find it to be an effective and reassuring option. As always, consult your healthcare provider before starting any new supplement.

While antacids neutralize stomach acid (which can sometimes cause rebound acid production), OBEX creates a physical barrier that blocks acid reflux without interfering with your natural digestion. This means you get relief without the potential for "acid rebound" that can occur with traditional antacids.

For optimal results, take OBEX within 30 minutes after your meal. The alginate needs stomach acid to form its protective barrier, so taking it on a full stomach ensures the best effectiveness. Many people also take a dose before bed if they experience nighttime reflux.

OBEX is ready to use and does not require mixing. We recommend starting with 1 teaspoon (5 mL). If needed, you can safely take more based on your symptoms.

OBEX is available in three chef-crafted flavours: Lemon Meringue, Smooth Mint, and Orange Cream. Unlike other alginate products with challenging tastes, our formulations were developed by professional chefs to make your heartburn relief something you actually look forward to taking.

Great question! Real mint can relax the lower esophageal sphincter, and citric acid increases stomach acidity—both of which can worsen reflux. However, OBEX uses natural flavour oils, not actual mint leaves or citrus fruit. These flavour oils provide the pleasant taste without the compounds that trigger reflux symptoms. There's no citric acid in our formulations, so you get the enjoyable flavours without the reflux risk.

We ship across Canada with free shipping on orders of 6+ bottles. Most orders arrive within 3-7 business days depending on your location. All products are made fresh in Hamilton, Ontario and shipped directly to your door with tracking provided.

Yes, research shows that alginate therapy can be used as an add-on to existing treatments like PPIs. In fact, studies found that 72% of patients reported improved satisfaction when adding alginate to their PPI regimen. However, we recommend spacing out your doses and consulting with your healthcare provider.

Yes! We're proud to partner with McKnight's Pharmacy as our first retail location. You can find OBEX at both of their Hamilton stores: 685 Main St E (at Proctor) and 460 Main St E (at Ontario). Just stop by during pharmacy hours to grab your bottles—no shipping wait required!
