Is Mushroom Coffee Good for Diabetics? What Science Says

So, you’ve swapped your sugary cereal for steel-cut oats and your soda habit for sparkling water — bravo! But what about that daily cup of coffee?
If you’re managing diabetes, you might’ve seen a video or two about mushroom coffee. Is it just a trend, or does it actually do something helpful for blood sugar? In this article, we’ll answer every question you have.
Does Mushroom Coffee Have Mushrooms in It?
Mushroom coffee is like your regular cup of joe, but it has some extra-special ingredients. And before you ask, no, it doesn't taste like a sautéed portobello. Instead, mushroom coffee blends traditional coffee beans with powdered or extracted functional mushrooms to add extra benefits.
Here's a breakdown of what could be in your cup:
- Chaga: Rich in antioxidants, this mushroom has been studied for its potential to support healthy blood sugar and immune function.
- Lion’s Mane: Known for its nootropic benefits, this mushroom may support cognitive function and encourage gut health.
- Cordyceps: This mushroom is believed to boost endurance and energy without the caffeine crash.
- Reishi: This mushroom is often touted for immune modulation and stress relief.
- Maitake: This mushroom has been studied for its ability to improve insulin sensitivity in animal models.
While many blends use cheap fillers like mycelium grown on grain, our Mushroom Coffee+ is made from 100% fruiting bodies. That means there’s more of the stuff you want and less of the stuff you don’t. Plus, our mushroom coffee contains way less caffeine than traditional brews (clocking in at 45 mg per serving), making it easier on your nervous system.
Can Mushroom Coffee Help Diabetics?
Mushroom coffee can have crazy benefits, but do any of these benefits translate specifically for diabetics? Read on to learn more.
Supports a Healthy Blood Sugar
Chaga mushroom has been studied for its potential to support balanced blood sugar levels. Research has found that chaga extracts can support insulin sensitivity and encourage a healthy glucose metabolism in diabetic mice.
These benefits are thanks to polysaccharides and antioxidant compounds like betulinic acid, which may help reduce oxidative stress, a known contributor to insulin resistance. While we’re still waiting on large-scale human trials, early results are promising enough to make chaga a centerpiece in the world of blood sugar–friendly fungi.
Relieves Feelings of Stress
Managing diabetes isn’t just about numbers — it’s about stress, too. Elevated stress can increase cortisol, which in turn can spike blood sugar. That’s where lion’s mane mushroom and L-theanine (an amino acid naturally found in tea) can come into play.
Lion’s mane can support the nervous system and encourage a balanced mood by influencing gut health and overall brain health. Meanwhile, L-theanine promotes alpha brain waves, which are associated with relaxation. A calmer body means a stable blood sugar response, especially when life throws curveballs like traffic jams or surprise carb counts.
Provides Fiber
When people think about fiber, they usually picture bran muffins, not mushrooms — but fungi have a sneaky type of fiber called beta-glucans. These soluble fibers can help slow the absorption of sugar in the digestive tract, which means fewer spikes and crashes in blood glucose.
Research also shows that beta-glucans can bind to receptors on immune cells and influence metabolic pathways that support glycemic control. Plus, they feed your gut’s good bacteria, which play a surprising role in everything from mood to insulin sensitivity.
Supports Insulin Sensitivity
Believe it or not, caffeine can support your insulin sensitivity, but only in small, steady doses. Some studies suggest that moderate caffeine intake may support insulin function by encouraging glucose uptake. However, too much can cause spikes in cortisol, which we already know isn’t good for your blood sugar.
Luckily, L-theanine actually has a unique synergy with caffeine that allows you to experience the motivation and energy from your morning cuppa without the dreaded stress and crash. Plus, our Mushroom Coffee+ contains only 45 mg of caffeine per serving. It’s enough to help you feel awake, but it shouldn’t cause the stress spikes or jitters that come with caffeine overdose.
Provides Stable Energy
We’ve all experienced a caffeine crash. It hits mid-morning, feels kind of like a blood sugar dip, and has you reaching for another cup (or a sugary snack to wake you up).
However, the crash is a thing of the past with mushroom coffee (or at least some brands). Thanks to our use of L-theanine, you can get smooth, long-lasting energy that shouldn’t spike your cortisol or send your nervous system into overdrive.
Our mushroom coffee also contains collagen, which is rich in amino acids like glycine and proline that can help fuel muscle tissue and maintain energy over time. For people with diabetes, stable energy means fewer cravings, fewer blood sugar swings, and a much more productive day.
Protects Against Oxidative Stress
Oxidative stress might be a buzzword, but it’s also a real metabolic menace, especially for people with diabetes. When blood sugar levels are high, your body produces more free radicals, which can damage cells, worsen inflammation, and interfere with insulin signaling.
Cue chaga mushroom. Chaga is packed with polyphenols, melanin, and superoxide dismutase (fancy name, big impact), all of which help neutralize free radicals and minimize their effects.
Studies show that chaga can even support antioxidant enzyme levels. By reducing oxidative stress, chaga may help preserve insulin function and protect organs commonly affected by diabetes, like your heart, kidneys, and even your eyes.
Practical Tips for Diabetics
If you’re living with diabetes and thinking about giving mushroom coffee a try, there are a few things to keep in mind.
These include the following:
- Choose Quality Blends: Look for mushroom coffee made with fruiting bodies and dual extracts, clearly labeled with dosages. Avoid brands that play hide-and-seek with their ingredient list.
- Watch for Additives: Skip blends with added sugar, artificial creamers, or mystery flavorings. Stick to unsweetened or naturally flavored options.
- Start Small: Everyone’s body reacts differently. It may be wise to begin with a half dose or smaller serving and track your blood sugar response.
- Consult Your Healthcare Provider: This is especially necessary if you’re on blood sugar-lowering medications, as some mushrooms can enhance those effects.
- Don’t Ditch Your Meds: Mushroom coffee can support your health, but it’s not a substitute for insulin, metformin, or your doctor's wisdom.
- Stay Consistent: Like with most functional foods, the magic isn’t instant. Give your body a few weeks to adjust and assess how you feel.
The Bottom Line
Mushroom coffee is a trend, sure — but it’s a trend with some weight to it. With ingredients like chaga, lion’s mane, L-theanine, and collagen, it can support stable energy, insulin sensitivity, and feelings of relaxation.
While it’s not a replacement for medication or medical advice, mushroom coffee can be a powerful addition to a diabetes-friendly routine. And if you want to try it for yourself, it’s as easy as checking out our selection of mushroom blends. Once you try it, there’s no going back!
