The best zero sugar drinks for diabetes are water, unsweetened sparkling water, unsweetened coffee and tea, and sugar-free sports drinks like Gatorade Zero and Powerade Zero. None of them add sugar, and as a registered dietitian living with type 1 diabetes, these are my go-tos.
Sugary drinks are one of those things that can make blood sugar harder to manage fast, and sometimes you do not realize how much they are affecting you until you start paying closer attention. I know for me, having a few zero sugar drink options I actually enjoy makes it a whole lot easier to stay hydrated without feeling like my only choice is plain water all day long.
I’ll also cover what “zero sugar” actually means on a label, which sweeteners you’ll run into, and when Gatorade Zero and Powerade Zero make sense.
Zero Sugar Drinks Help Most When They Replace Sugary Ones
Zero sugar drinks can be a great tool for people with diabetes or anyone who pays attention to blood sugar. They help maintain more stable blood sugar levels while keeping you hydrated and refreshed. And they can also help you cut back on the amount of added sugar or refined sugar you consume if you enjoy them in place of a sugary beverage.
Not all zero sugar drinks need to play the same role in your routine. Some are great for everyday hydration, while others are better enjoyed in moderation.
“Zero Sugar” Means Less Than 0.5 Grams of Sugar Per Serving
This is one of the most common points of confusion when people are shopping for sugar-free drinks for diabetes.
Under FDA labeling rules, “zero sugar” or “sugar free” generally means the product contains less than 0.5g sugar per serving. “No sugar added” is a little different. That means no sugars were added during processing, but the product may still contain naturally occurring sugar. So even when a front label looks reassuring, it is still worth checking the Nutrition Facts panel.
How to choose zero sugar drinks for diabetes
A lot of zero sugar drinks exist on the market. Everything from plain water to artificially sweetened diet sodas. Some are great to consume frequently and others are best consumed in moderation.
When you’re looking for a zero sugar drink for diabetes to enjoy, remember that these beverages should not be replacing your daily water intake. Instead, they can help supplement your fluid intake and offer variety without the extra sugar.
I also recommend thinking about a few things:
- Is this something I want for everyday hydration or just once in a while?
- Does it truly have zero sugar and zero carbohydrate?
- Does it contain caffeine or alternative sweeteners I may want to moderate?
- Is it actually satisfying, or am I going to want something else right after?
Alternative sweeteners in zero sugar drinks
Sweetened zero sugar drinks will contain alternative sweeteners. When the FDA approves an alternative sweetener or a non-nutritive sweetener for use in the U.S., they designate an Acceptable Daily Intake level. The ADI is the amount a person can safely consume each day for a lifetime.
It would be incredibly difficult for most people to actually reach the ADI for any sweetener. Alternative sweeteners should be viewed as a tool to use when managing diabetes. Which sweeteners you choose to consume can depend on your flavor preferences, the type of beverage you’re drinking, and how often you want to include them. You don’t have to use them, but moderate amounts are fine if you enjoy them.

Zero Sugar Soda Works Best as an Occasional Swap
As we discussed above, some zero sugar beverages are best consumed in moderation or only occasionally. Zero sugar soda is one of those beverages. It can be a great alternative when you’re craving a soda or another type of sugary beverage, but it is not something that should be consumed excessively or in place of water.
Save it for when you’re craving a soda and reach for water the rest of the time.
Best zero sugar drinks for diabetes
From naturally flavored waters to teas and electrolyte drinks, there are a lot of refreshing sugar-free drink options for people with diabetes to choose from.
1. Water
Water is an obvious first choice for people with diabetes. And it would be a bit weird not to have it on our list. So we’ll get it out of the way first as a zero sugar drink option for diabetes. It has zero calories, zero carbohydrates, and zero sugar, making it one of the easiest beverages for people with diabetes to enjoy. Staying hydrated with water also supports overall health and healthy blood sugar management.
2. Infused water
Adding fresh fruit, herbs, or vegetables to water enhances the flavor without significantly increasing sugar or calorie intake. You can infuse water with so many different things:
- Lemon
- Cucumber
- Mint
- Raspberries
- Lime
- Oranges
- Strawberries
And more.
Infused water is a great alternative to flavored sugary beverages because it keeps hydration levels up while avoiding high-sugar drinks. If plain water feels boring, this is one of the easiest ways to make it more appealing.
3. Unsweetened coffee
Coffee, without high-sugar creamers and sweeteners, has been linked in research to improved insulin sensitivity and a lower risk of type 2 diabetes, though of course that does not mean coffee is a treatment. It can be a nice zero sugar drink for diabetes if you enjoy it in moderation and keep an eye on what you add to it. Keep in mind that too much coffee may raise blood sugar and can impact insulin resistance in some people.
If you can’t do coffee without creamer (I love my creamer, too!), check out the best coffee creamers for diabetes, so you can still enjoy your morning cup of Joe without spiking your blood sugar!
4. Unsweetened sparkling water
Unsweetened sparkling water is one of my favorite alternatives to sugary soda because it offers the carbonation I love without large amounts of added sugar. Flavored versions without added sugar can provide some fun variety without raising blood sugar much, if at all.
Some of my personal favorite brands include:
- LaCroix
- Waterloo
- Spindrift
- San Pellegrino
- Bubly
- Store brands like Good & Gather at Target
One quick note here though. Not every sparkling water is exactly the same. Some products made with real juice can still contain small amounts of carbohydrate and sugar depending on the flavor, so it is always worth checking the label if you want something that is truly zero sugar.
5. Herbal tea
Herbal tea is naturally caffeine free and sugar free, making it one of the best zero sugar drinks for people with diabetes.
Common varieties include:
- Chamomile
- Peppermint
- Hibiscus
- Cinnamon
- Ginger
Herbal teas can offer anti-inflammatory properties, and some teas may offer small blood sugar benefits. But even beyond that, they are just a nice way to add more variety to your day without relying on sugary beverages.
6. Unsweetened iced tea
Unsweetened iced tea has no sugar, but it does have some caffeine. It offers hydration and antioxidants. Specifically, catechins found in green tea may support insulin function. Unsweetened iced tea is a refreshing alternative to sugary drinks without affecting blood sugar the way sweet tea can.
Some brands also offer naturally flavored options, which can be a fun way to mix things up. Some of my favorite brands include:
- Lipton
- Pure Leaf
- Snapple
7. Sweetened sugar-free iced tea
Flavored sugar-free iced teas use alternative sweeteners like stevia or other non-nutritive sweeteners. These can be a good option for people who want a sweet beverage without added sugar. They offer a nice alternative to high-sugar beverages while still giving you that sweet tea flavor.
Some of my favorite flavored tea brands include:
- Lipton
- Snapple
- Pure Leaf
- Arizona
8. Sugar-free sports drinks
Sugar-free sports drinks help replenish electrolytes lost through exercise or dehydration without adding extra sugar. They can be useful for people with diabetes who need to stay hydrated during workouts without the blood sugar spike that can come with traditional sports drinks. Most do contain artificial sweeteners though, so keep that in mind if that is important to you.
Some of my favorite options include:
- Propel Zero
- Gatorade Zero
- Powerade Zero
These are more of a situational drink than an all-day beverage. For most everyday hydration, water is still going to be the better first choice.
Gatorade Zero and Powerade Zero Are Good Picks for Sweaty Days
Both Gatorade Zero and Powerade Zero are zero sugar, and Powerade Zero lists 0 grams of carbs per 12-ounce serving and is sweetened with sucralose and acesulfame potassium. That makes either one a much better pick than a regular sports drink when you’re sweating through a workout or a hot day and want electrolytes without the sugar.
The one time to skip them is when you’re low. Zero sugar drinks won’t raise your blood sugar. The CDC recommends 15 grams of fast-acting carbs, like 4 ounces of juice or regular soda, then rechecking after 15 minutes. I break that down in my guide to the best snacks for low blood sugar.
Swapping Sugary Drinks for Zero Sugar Ones Makes Blood Sugar Easier to Manage
Replacing sugar-sweetened beverages with zero sugar options can make it much easier to manage blood sugar. That is one reason zero sugar drinks can be such a helpful tool for people with diabetes. They give you more choices without automatically loading extra sugar into your day.

FAQs About Zero Sugar Drinks and Diabetes
Zero Sugar Drinks Are a Helpful Swap for People Living with Diabetes
Zero sugar drinks can be a helpful option for people with diabetes, especially when they replace sugary beverages. They can help support hydration and make blood sugar easier to manage, depending on the drink and how often you include it.
Most Zero Sugar Drinks Barely Move Blood Sugar
Most zero sugar drinks will have little to no impact on blood sugar, but not every product marketed as healthy or light is actually zero carbohydrate or zero sugar. Reading the label is still important, especially with flavored sparkling waters or drinks made with juice.
Approved Sweeteners Fit in Moderation for Most People
For most people, approved non-nutritive sweeteners can fit in moderation. FDA sets Acceptable Daily Intake levels, and most people are nowhere close to those amounts in a normal day.
Unsweetened Sparkling Water Is a Great Soda Swap
Unsweetened sparkling water is a great option for people living with diabetes. It gives you flavor and carbonation without the sugar found in regular soda. Just check the label on products that use juice or fruit blends.
Zero Sugar Soda Is Fine in Moderation
Zero sugar soda can be a helpful option sometimes, but I would not make it your main source of fluids. Water and other unsweetened beverages are still the better everyday choices.
Gatorade Zero and Powerade Zero Work Best Around Workouts
Sugar-free sports drinks like Gatorade Zero and Powerade Zero are useful when you need electrolytes without extra sugar, especially after exercise or sweating. Skip them when your blood sugar is low, since they won’t bring it back up. For everyday hydration, water is still the simplest choice.
The best zero sugar drinks for diabetes are the ones that help you stay hydrated, fit your preferences, and make blood sugar easier to manage, not harder. I am a big fan of making diabetes care feel more doable, and sometimes that starts with something as simple as having a drink you actually want to reach for.
