Sodas Without Phosphoric Acid: The Full List, and What They Use Instead

Last reviewed: November 2026. Acid status for Coca-Cola, Diet Coke, Coke Zero Sugar, Pepsi, Pepsi Zero Sugar, Dr Pepper, Sprite, 7 Up, Fanta, Sunkist, Mountain Dew, and Poppi is from the U.S. labels we photographed in October and November 2026. Root beers, ginger ales, Zevia, and the Olipop and Poppi colas are from the manufacturers’ current published ingredient lists. Formulas change, so check the can.

People go looking for a soda without phosphoric acid for three reasons: a dentist mentioned enamel, a doctor mentioned bones or kidneys, or a renal diet put a number on phosphorus. The good news is that the list is long and easy to remember, because phosphoric acid is the cola acid. It’s in Coke, Pepsi, and Dr Pepper, in every diet and zero-sugar version of them, and in almost nothing else on the shelf. The less convenient news is that the sodas without it are still acidic and, in most cases, still carry 38 to 46 grams of sugar. Here’s the full list of Sodas Without Phosphoric Acid from the labels, what each one uses instead, and what the switch does and doesn’t buy you.

Quick answer: which sodas have no phosphoric acid?

Sodas Without Phosphoric Acid

Sprite and Sprite Zero Sugar Citric acid

The label we photographed lists citric acid and sodium citrate, and nothing from the phosphate family. A 12 oz Sprite has 38 g of sugar and no caffeine or color. Sprite Zero Sugar keeps the citric acid and swaps the corn syrup for aspartame and Ace-K, which makes it the easiest answer for someone who wants a zero-sugar soda with no phosphoric acid and no caffeine.

7 Up Citric acid

Six ingredients: filtered carbonated water, high fructose corn syrup, citric acid, natural flavors, potassium citrate, and calcium disodium EDTA. No phosphoric acid and no benzoate preservative either. The sugar matches Sprite at 38 g. Our 7 Up breakdown goes through all six.

Fanta and Sunkist Citric acid, dyed

Both orange sodas use citric acid. What they add instead is color: Yellow 6 and Red 40 in each. Fanta Orange has 44 g of sugar in 12 oz, more than a Coke, and no caffeine. Sunkist has a little less sugar and 19 mg of caffeine. If you’re leaving cola to get away from an additive, check that you haven’t traded it for two synthetic dyes.

Mountain Dew Citric acid, 46 g sugar

No phosphoric acid, and the least persuasive entry on the list. Mountain Dew uses citric acid, and it also has the most sugar (46 g) and the most caffeine (54 mg) of any mainstream soda, plus Yellow 5. Dental studies that rank sodas by how much enamel they dissolve put citrus sodas like this one at or above the colas.

Root beer: A&W, Mug, Barq’s None or citric

Root beer is brown because of caramel color, which leads people to assume it’s built like a cola. It isn’t. By their published lists, A&W has no added acid at all, and Mug and Barq’s use a small amount of citric acid. That makes root beer the least acidic of the mainstream sodas. The sugar is in the mid-40s per 12 oz, a little above a cola, and Barq’s is the one with caffeine.

Ginger ale and cream soda Citric acid

Canada Dry and Schweppes ginger ales use citric acid. So do most cream sodas. Sugar is in the mid-30s per can, slightly under a cola.

Poppi and Olipop Vinegar, juice, tartaric acid

The prebiotic sodas get their tartness from food acids. The Poppi can we photographed lists apple cider vinegar and fruit juice, with 5 g of sugar. Olipop uses juice concentrates and lemon or lime juice, with 2 to 5 g of sugar. Both are the rare entries here where the sugar problem is solved as well.

The three colas without it: Zevia, Olipop, Poppi Cola, no phosphoric acid

If what you want is cola flavor, these are the only widely sold options. Zevia Cola is sweetened with stevia and acidified with citric and tartaric acid, with no caramel color and 45 mg of caffeine. Olipop Vintage Cola uses lime juice and has 50 mg of caffeine from green tea. Poppi Classic Cola uses apple cider vinegar and tartaric acid, with 40 mg of caffeine. None of them tastes exactly like a Coke, and the missing phosphoric acid is part of why: it gives cola a dry, sharp bite that fruit acids don’t reproduce.

Acid on the label: the table

Three things to notice. The phosphoric acid column splits exactly along the cola line, and diet or zero versions never change which side a soda is on. The sugar column barely moves between the two halves, so a switch from Coke to Sprite removes one acid and one gram of sugar. And the only rows that are green in both columns are Sprite Zero Sugar, Poppi, and Olipop.

Which sodas have phosphoric acid?

The colas, and the two “pepper” sodas that are built on a cola base. From the labels: Coca-Cola, Diet Coke, and Coke Zero Sugar; Pepsi, Diet Pepsi, and Pepsi Zero Sugar; Dr Pepper and Dr Pepper Zero Sugar; plus Cherry Coke, Pibb Xtra, RC Cola, and store-brand colas. Pepsi and Diet Coke list citric acid as well, on top of the phosphoric. The quick test on any can: if it’s brown and it isn’t root beer, expect phosphoric acid until the ingredient list says otherwise.

Why avoid phosphoric acid? (And should you?)

Here are the reasons people give, with what the evidence says about each.

“It’s bad for my teeth.” True, and so is its replacement. Enamel starts to dissolve below about pH 5.5. Colas sit around 2.5, Dr Pepper around 2.9, and Sprite and 7 Up around 3.3. That’s a real gap on paper, but citric acid also binds calcium, and lab studies that soak teeth in soda find citrus sodas erode enamel as much as colas do, sometimes more. Switching acids doesn’t protect your teeth. Drinking it with a meal, through a straw, and not sipping one can for an hour does.

“It’s bad for my bones.” This is the finding that’s specific to cola. In the Framingham Osteoporosis Study, women who drank cola daily had lower hip bone density, and other carbonated drinks showed no such link. It’s an association, not proof: the effect could come from phosphoric acid, from caffeine, or from cola taking milk’s place in the diet. If bone density is your concern, switching from cola to a non-cola soda is consistent with the evidence, and switching to milk or water is better supported.

“It’s bad for my kidneys.” A 2007 case-control study found that two or more colas a day went with roughly double the risk of chronic kidney disease, for regular and diet cola alike, and found no link for non-cola sodas. That points at the phosphoric acid and not the sugar. For kidney stones the picture is different: a large cohort study found sugar-sweetened non-cola sodas raised stone risk at least as much as sugared colas, so leaving cola for Sprite doesn’t help there.

“My renal diet limits phosphorus.” This is the strongest reason, and it gets its own section below.

Our phosphoric acid explainer goes through the studies one by one.

What the sodas without it use instead

Citric acid. The acid in nearly every non-cola soda. It gives a brighter, fruitier tartness, and it’s a normal part of human metabolism. Its one cost is dental, as above.

Citrate salts. Sodium citrate in Sprite and potassium citrate in 7 Up buffer the acid so the tartness stays even. They’re harmless at these amounts.

The same sugar. This is the part the acid question hides. Sprite and 7 Up have 38 g, Coke has 39, Fanta has 44, and Mountain Dew has 46. The research on daily sugared soda (weight gain, type 2 diabetes, fatty liver) applies to all of them equally, and it’s far stronger than anything known about phosphoric acid. Our corn syrup breakdown covers it.

Dyes, in the fruit sodas. Cola’s color is caramel. Leave cola for orange or citrus soda and you pick up Yellow 5, Yellow 6, or Red 40.

Fruit acids and vinegar. Tartaric acid, lime juice, and apple cider vinegar in the Zevia, Olipop, and Poppi colas. These are the only swaps on this page that don’t bring a new question with them.

If you’re on a low-phosphorus diet

For people with chronic kidney disease, phosphoric acid matters for a specific reason. The phosphorus in additives is absorbed almost completely, while the body takes up roughly half of the phosphorus that occurs naturally in food. A 12 oz cola carries about 50 mg of it. That’s why renal dietitians single out dark colas and usually allow clear sodas.

Two cautions from the labels. First, “no phosphoric acid” is not the same as “no phosphate.” Sports drinks use phosphate salts as electrolytes: the Gatorade bottle we photographed lists monopotassium phosphate, and Prime Hydration lists dipotassium phosphate. Scan any ingredient list for the letters “phos.” Second, the clear sodas that pass the phosphorus test can fail a potassium or fluid limit. Your own lab numbers decide this, so run the list past your nephrologist or renal dietitian.

Sodas without phosphoric acid: the verdict

The concerns in a soda without phosphoric acid, ranked by evidence:

1. Sugar. 38 to 46 g a can in the sugared ones. This is the clearest long-term harm in any soda, and it’s unchanged by the switch.
2. Enamel erosion. Citric acid plus sugar, sipped slowly. It’s comparable to cola.
3. Synthetic dyes. Yellow 5, Yellow 6, and Red 40 in Mountain Dew, Fanta, and Sunkist.
4. Sweeteners in the zero versions. Aspartame and Ace-K in Sprite Zero Sugar. Evidence of harm at normal intake is weak.
5. Everything else. Citrate salts, EDTA, and benzoate are minor at these amounts.

Phosphoric acid-free sodas for kids, pregnancy, and kidney disease

Kids: the bone research is one more reason not to make cola a child’s daily drink, since those are the bone-building years. A clear soda removes the cola acid and the caffeine and keeps all the sugar. Milk and water are still the answer.

Pregnancy: phosphoric acid isn’t a pregnancy concern at soda amounts. Caffeine and sugar are, and the caffeine-free sodas on this list (Sprite, 7 Up, Fanta, most root beer and ginger ale) take care of the first. Our guide to which sodas have caffeine has the numbers.

Kidney disease: clear sodas over dark colas is standard renal-diet advice. Check potassium, fluid limits, and hidden phosphate additives with your care team.

Cleaner alternatives

For cola flavor without the acid: Zevia Cola, or an Olipop or Poppi cola. For a zero-sugar soda with no phosphoric acid and no caffeine: Sprite Zero Sugar or Zevia Lemon Lime. For the fizz with no acid added at all: plain sparkling water or club soda. Flavored seltzers add a little citric acid and nothing else.
