Baking soda, or bicarbonate of soda, is an indispensable multi-purpose essential in every home. Its applications—from cooking to cleaning—are virtually endless.
Yet, tracking it down in stores can be tricky. Supermarkets, organic shops, DIY centers—we've done the legwork to pinpoint exactly where to find it, saving you time and frustration.
Here's where to buy baking soda effortlessly. Read on:

In major supermarkets, baking soda is widely available. Think Leclerc, Carrefour, Lidl, Aldi, Super U, Hyper U, Intermarché, Auchan, Casino, Monoprix, Spar, Leader Price, Action, and Gifi.
To skip the hunt, check these spots first: most often, it's in the condiments section near salt and spices, like La Baleine brand—guaranteed food-grade since it's in the food aisle.
It may also appear by flours and yeasts, as it doubles as a leavening agent in baking.
The biggest selection? Head to the household products aisle for technical baking soda from brands like Biovie, Starwax, Paulette, Briochin, Onyx, The Green Tree, You Make, and The Bicarbonate Company.
Organic retailers like Biocoop, La Vie Claire, Satoriz, Marcel et Fils, and Naturalia have stocked baking soda for years—it's 100% natural and budget-friendly.
Brands include Marius Fabre, The Soapmaker, Maison Pinson, The Ecological Drugstore, and Nature et Partage. Look in the natural household products section.
Many also feature DIY cosmetics aisles with Orfito, Anaé, or MyCosmetik for deodorants and hygiene products.
Food-grade options, like Ah Table!, sit in the culinary section.
DIY giants such as Castorama, Bricomarché, Brico-Marché, Leroy Merlin, and Mr Bricolage carry it, typically near cleaning products.
Garden centers like Villa Verde, Jardiland, Truffaut, Gamm Vert, and Botanic stock it too—for weedkillers, pool maintenance, and more—in garden care, hygiene, or health sections.
For medicinal uses—like dental care, digestion aid, or skin remedies—pharmacies offer the purest, finest grades, though at a premium price. Brands like Gifrer are common.
Ask the pharmacist directly, as layouts vary. In parapharmacies, check oral hygiene or alternative medicine shelves.
Online shopping skips the search: best prices, home delivery, and packs from 500g to 6kg in boxes, jars, or bags.
Stick to reputable sites to avoid counterfeits and watch delivery fees.

They're chemically identical—sodium bicarbonate—but differ in purity and purpose.
Food-grade is ultra-refined for ingestion, cooking, or cosmetics (check for 'food baking soda' on labels). It's pricier but versatile.
Technical grade suits cleaning and DIY—non-edible, yet highly effective and cheaper (around €4/kg).
Food-grade wins for versatility across cooking, cleaning, and beauty. For a cost-effective large pack at €2.17/kg, opt for quality food-grade.
If solely for household tasks, technical baking soda suffices.
