Updated September 9, 2026
Sprite Zero Sugar Lemon-Lime
Sprite Zero
Sprite Zero Sugar Lemon Lime is generally a reasonable occasional choice during pregnancy, with a B+ ingredient based grade. Its aspartame and potassium benzoate are rated likely safe at ordinary food and drink exposures, although direct pregnancy evidence for benzoates is limited. If you have phenylketonuria (PKU), avoid or restrict aspartame according to your metabolic care plan.
Go ahead and use it. Nothing to worry about here.

What Ingredients Are in Sprite Zero Sugar Lemon-Lime?
Sprite Zero Sugar Lemon-Lime has 7 ingredients. All 7 ingredients are considered safe or likely safe for pregnancy.
aspartame
LIKELY SAFE
Aspartame is a low calorie artificial sweetener commonly used to sweeten foods and beverages. Aspartame is considered acceptable during pregnancy within established intake limits for most people, but requires avoidance or restriction if you have PKU.
potassium benzoate
LIKELY SAFE
Potassium benzoate is a preservative commonly used to inhibit the growth of bacteria, yeast, and molds in food and beverage products. Potassium benzoate is generally low concern at regulated food additive amounts during pregnancy, though evidence relies mainly on additive reviews and animal studies rather than direct human pregnancy data.
acesulfame potassium
SAFE
Acesulfame potassium is a calorie free artificial sweetener commonly used to enhance the sweetness of food and beverages. The available potassium evidence concerns normal dietary mineral intake during pregnancy, not a direct pregnancy assessment of acesulfame potassium as a sweetener.
carbonated water
SAFE
Carbonated water is water infused with carbon dioxide gas, creating a fizzy, bubbly sensation. Water from a safe source supports pregnancy hydration, although the water evidence does not assess the finished soda.
citric acid
SAFE
Citric acid is a natural organic acid commonly used as a preservative and flavor enhancer in food and beverages. Citric acid is generally compatible with pregnancy at ordinary food amounts, though acidic drinks may aggravate reflux or dental irritation.
potassium citrate
SAFE
Potassium citrate is a salt used as a dietary supplement and medication to help prevent kidney stones and regulate pH levels in the body. Normal dietary potassium intake is compatible with pregnancy, while concentrated supplements and potassium restrictions for kidney disease require separate clinical guidance.
natural flavors
SAFE
Natural flavors are derived from plant or animal sources and used to enhance the taste of food and beverages. Natural flavors are unflagged, but their unspecified composition does not establish pregnancy specific safety.
Answering Your Questions
How much Sprite Zero Sugar Lemon-Lime is safe during pregnancy?
If you want some, pour a small glass rather than treating it as your main hydration drink. Ingredient amounts per serving are not available here, so there is no reliable product specific maximum to recommend.
Can you use Sprite Zero Sugar Lemon-Lime daily while pregnant?
Enjoy it occasionally and choose water for most of your daily hydration. Cut back if the acidity aggravates heartburn, and consider your other sources of aspartame rather than looking at this drink alone.
Why does Sprite Zero Sugar Lemon Lime receive a B+ grade?
The B+ comes from ingredient based scoring, with aspartame and potassium benzoate contributing likely safe ratings. Aspartame is considered acceptable within established intake limits for most people, while benzoate preservatives are generally low concern at regulated food amounts but have limited direct pregnancy evidence. The grade is not proof that every ingredient or the finished drink has been studied during pregnancy.
Does Sprite Zero Sugar Lemon Lime contain caffeine?
This lemon lime variant is caffeine free. Check your package if you buy a different variant or a product from another country; caffeine free does not mean a drink should replace water.
Does aspartame cross the placenta?
Aspartame is broken down after you consume it, and its breakdown products can cross the placenta. That does not by itself demonstrate harm from ordinary dietary exposure: regulatory assessments consider approved use acceptable within established intake limits. PKU is an important exception because aspartame supplies phenylalanine.
Can I drink it while breastfeeding?
The pregnancy grade is not a separate breastfeeding assessment. Aspartame itself is not detectable in breast milk after maternal consumption, but acesulfame can enter milk and its effects on nursing infants remain uncertain; keeping diet drinks occasional is a cautious approach. If you or your baby has PKU, discuss aspartame with your care team. LactMed: Aspartame, LactMed: Acesulfame
What can I drink instead during pregnancy?
Choose plain water or unsweetened sparkling water if you want a drink without aspartame and potassium benzoate. Check flavored water labels for sweeteners and preservatives, and choose plain still water if acidic drinks bother your reflux.
Is zero sugar soda automatically a better pregnancy choice?
Zero sugar avoids the sugar in regular soda, but it does not make the drink a nutritional necessity or remove all ingredient considerations. This product still contains sweeteners and a preservative, so water remains a simpler everyday choice.

B - Likely Safe
Pretty much safe with very minimal risk. Some ingredients may have limited pregnancy studies, but no significant safety concerns have been identified.
What to do: Use with confidence.
C - Limit
Contains ingredients with some pregnancy considerations. Research shows these ingredients may have limited safety data, potential for minor hormonal effects, or require caution based on animal studies.
What to do: Use sparingly and consider safer alternatives when available.
D - Caution
Similar to C grade but contains multiple cautionary ingredients. The combination increases overall concern.
What to do: Try to avoid if that makes you feel better. If you've already used it, no need to panic.
F - Avoid
Contains an ingredient Pregnancy Safe recommends avoiding during pregnancy. This may reflect an established risk or a precaution based on limited evidence; check the ingredient guidance and exposure context.
What to do: Do not use during pregnancy. If you've already used it, don't worry - contact your OBGYN if concerned.
