5 Drinks That Help Lower Blood Sugar Naturally
If you’ve been working to improve insulin resistance, balance your blood sugar, or reverse prediabetes or type 2 diabetes, what you drink matters just as much as what you eat.
Some drinks can spike your blood sugar without you realizing it—while others can actually help lower your blood sugar and improve your insulin sensitivity. In this post, I’m sharing 5 drinks that can help support more stable blood sugar levels throughout the day.
I’m Kait, a nutritionist who specializes in insulin resistance and blood sugar. I’ve helped hundreds of people use simple food and lifestyle changes to regain energy, reduce cravings, and reverse metabolic dysfunction. Let’s talk about what to drink!
1. Coffee with Allulose or Protein
If you’re already a coffee drinker, you’ll be happy to know that coffee has been shown in several studies to improve insulin sensitivity and lower the risk of type 2 diabetes.
But what you add to your coffee makes a difference. Skip the sugar and sweetened creamers. Instead, try:
Black coffee
Coffee with a scoop of collagen or protein powder
Coffee sweetened with allulose (a rare sugar that doesn’t spike blood sugar)
Allulose is my top choice because it tastes like sugar but has no impact on glucose or insulin levels.
2. Apple Cider Vinegar in Water
Apple cider vinegar (ACV) is a well-known blood sugar hack that works when taken before meals.
Studies show that taking 1 tablespoon of ACV diluted in water before a carb-containing meal can:
Slow the breakdown of carbs
Reduce the glucose spike from that meal
Improve fasting blood sugar the next morning
You can also take it before bed to help with overnight and morning blood sugar.
How to use it: Mix 1 tbsp ACV with water and a pinch of sea salt, drink it before meals or before bed.
3. Cinnamon Tea or Ceylon Cinnamon in Water
Cinnamon—especially Ceylon cinnamon—has blood sugar-lowering properties.
It works by improving insulin sensitivity and slowing gastric emptying, which helps reduce post-meal blood sugar spikes.
How to use it:
Steep cinnamon sticks or Ceylon cinnamon powder in hot water
You can also add cinnamon to coffee, smoothies, or sprinkle on meals
Just avoid taking too much cassia cinnamon (common in supermarkets), as it can be harmful in large doses.
4. Chromium-Enhanced Sparkling Water
There’s a new category of blood sugar-supporting drinks that include ingredients like chromium and amino acids.
One of my favorites, GOOD IDEA, contains a blend of chromium, amino acids, and electrolytes. These work together to:
Improve insulin sensitivity
Support carbohydrate metabolism
Help reduce the spike in blood sugar from meals
This is a great option before high-carb meals or even between meals to support stable energy.
5. Sleep Support Drinks with GABA or Magnesium
Poor sleep increases insulin resistance—so improving your sleep quality can have a major impact on your blood sugar levels.
Sleep support drinks that contain ingredients like GABA, magnesium, or L-theanine can:
Help you fall asleep faster
Support deeper, more restorative sleep
Reduce morning blood sugar levels by improving overnight regulation
How to use it: Look for sugar-free nighttime drinks or powders that include these ingredients and take them 30-60 minutes before bed.
Final Thoughts
If you’re struggling with cravings, low energy, or high blood sugar—what you drink can make a big difference. Here’s a quick recap:
Coffee with allulose or protein helps stabilize blood sugar
Apple cider vinegar in water reduces post-meal and fasting glucose
Cinnamon tea boosts insulin sensitivity
Chromium-enhanced drinks support better carb metabolism
Sleep support drinks improve insulin sensitivity overnight
Try adding one or two of these into your daily routine and see what difference it makes. And if you’re testing your blood sugar, you’ll likely see the results on your meter too.
