What is the primary function of ENO powder and how does it work?

ENO is designed to neutralise excess stomach acid; the sodium bicarbonate and sodium carbonate react with citric acid to produce carbon dioxide bubbles, creating an alkaline solution that temporarily relieves heartburn and indigestion.

Is the sodium content of ENO a concern for individuals on a low-sodium or hypertension diet?

Yes, each dose contains a substantial amount of sodium from the bicarbonate and carbonate salts, so people who need to limit sodium intake should use ENO only under medical advice.

How should ENO be stored after opening to preserve its efficacy?

Store the powder in a tightly sealed container in a cool, dry place away from moisture and direct heat to prevent clumping and maintain its effervescent properties.

Product Insights

ENO is a 200g powdered antacid supplement sold at Woolworths and Coles, formulated with sodium bicarbonate, sodium carbonate and citric acid. The blend creates an effervescent reaction that quickly neutralises excess stomach acid, offering fast relief from heartburn and indigestion. However, the product delivers a high sodium load from the bicarbonate and carbonate salts and includes food-additive E-numbers, which may be unsuitable for those on low-sodium or additive-sensitive diets.

Comparative Analysis

ENO stands out in the antacid segment by delivering a minimalist three-ingredient, fast-acting effervescent formula that differentiates it from multi-ingredient heartburn remedies.
