I started taking berberine after struggling with unpredictable blood sugars, even while eating low carb. I was looking for a natural way to support my body while managing type 2 diabetes, and that's when I found the combination of berberine and quercetin.
I now take them daily as part of my routine, and they've helped me feel more balanced. Here's why this combo works and how it's made a real difference in my journey.

When I was first diagnosed with type 2 diabetes in my 40s, I was overwhelmed. Like most people, I followed the advice the doctor gave me: eat better, exercise, take metformin and hope for the best.
But "eating better" didn't work the way I expected. The doctor never explained what "eating better" meant and didn't discuss with me anything about berberine vs metformin. My blood sugars still spiked, I felt tired all the time, and I never really felt in control. That's what prompted me to try a low-carb diet, and honestly, it changed everything.
That's also why I started my blog, I Hacked Diabetes. I wanted to share what I was learning in real time, not just recipes, but the real-life tools and strategies that were helping. One of those tools? A daily combo of berberine and quercetin.
Why do I follow a low-carb lifestyle?
For me, low carb isn't about restriction, it's about being stable. When I started cutting carbs, especially refined ones, my blood sugars stopped spiking as often and I had more energy and few crashes. My blood sugars started to normalize quickly. Following a low carb meal plan has helped with blood sugar support. I also found being part of a group with similar supportive people beneficial like the IHD Inner Circle.
But even with low-carb eating, I often would still have cravings and would still have moments of being off balance. This is when I started exploring natural supplements that could support what I was already doing. I started taking berberine and although it helped a bit I still felt I could be doing something else.
Berberine for Diabetes: How I Use It with Quercetin Daily
After some research (and a lot of trial and error), I landed on a combination that's worked well for me: berberine and quercetin.
Here's why I take it:
- Berberine is believed to help the body use insulin more effectively, which in my experience, seems to make post-meal blood sugar responses more stable.
- Quercetin is often studied for its potential to reduce inflammation, something many of us with type 2 diabetes deal with, even if we don't feel it.
Together, these two have helped smooth out my blood sugar curves and made my low carb lifestyle even more effective. It's not a miracle cure, but it feels like an extra layer of support.
Scientific Evidence Supporting Their Use
Clinical Studies on Berberine
Berberine, a natural compound found in several plants, has been extensively studied for its potential benefits in managing type 2 diabetes.
Glycemic Control: A randomized clinical trial involving 36 adults with newly diagnosed type 2 diabetes compared berberine to metformin over a 3-month period. A study published in the journal Metabolism found that berberine appeared to reduce fasting blood glucose and HbA1c levels in individuals with type 2 diabetes. The results were similar to those seen with metformin. (Source)
Insulin Sensitivity: Berberine has been shown to improve insulin sensitivity by activating the AMP-activated protein kinase (AMPK) pathway, which plays a crucial role in regulating glucose uptake and metabolism.
Inflammation Reduction: A meta-analysis of six clinical trials indicated that berberine markedly lowered C-reactive protein (CRP) levels in patients with type 2 diabetes, suggesting its role in reducing systemic inflammation associated with insulin resistance. (Source)
Clinical Studies on Quercetin
Quercetin, a flavonoid found in many fruits and vegetables, has been studied for its potential effects on blood sugar regulation and metabolic health.
- Blood Glucose Reduction: Animal studies have demonstrated that quercetin supplementation can lower blood glucose levels and improve glucose tolerance in diabetic models. (Source)
- Insulin Secretion: Quercetin has been observed to enhance insulin secretion and protect pancreatic β-cells from oxidative stress, thereby supporting insulin production and function.
- Lipid Profile Improvement: In hyperlipidemic animal models, quercetin supplementation resulted in decreased levels of triglycerides, total cholesterol, and LDL cholesterol, while increasing HDL cholesterol levels, indicating its potential in managing dyslipidemia associated with type 2 diabetes.

Combined Supplementation Studies
Emerging research suggests that the combination of berberine and quercetin may offer synergistic benefits in managing type 2 diabetes.
- Enhanced Glycemic Control: A study published in the journal Frontiers in Physiology found that the combined administration of berberine and quercetin significantly improved insulin resistance and reduced inflammation in obese rats, more so than either compound alone. (Source)
- Improved Bioavailability: Research into a synthesized berberine-quercetin salt (BQS) demonstrated enhanced dissolution efficiency and bioavailability compared to individual compounds, suggesting that combined formulations may offer improved therapeutic outcomes. (Source)
- Neuroprotective Effects: A study investigating the effects of berberine and quercetin on glucose transporters and insulin signaling in the brain found that both compounds could modulate glucose homeostasis, potentially offering neuroprotective benefits in diabetic conditions. (Source)
What I've noticed since taking Berberine and Quercetin
While this is just my personal experience and not medical advice, I've noticed:
- Post-meal readings tend to be lower
- Energy feels more consistent
- Less daily variability
This combo didn't "fix" anything, but it became a helpful tool in managing my day-to-day patterns.
Pro Tip
Make sure your berberine supplement lists the dosage (typically 500mg per capsule) and is free from fillers. I use one that combines it with quercetin so I only need one capsule a day.
Common Mistakes People Make with Berberine and Quercetin
- Taking them inconsistently
- Using low-quality brands without 3rd-party testing
- Not adjusting carbs or meals
- Expecting instant results
How It Fits Into My Routine
I keep it simple: best time to take berberine for diabetes? I take one capsule of the Berberine and Quercetin supplement daily with my biggest meal (usually before a meal), based on what works best for me. Some people may need different timing or dosages, so always talk to a healthcare provider.
I still eat low carb, I still move my body, and I still track my blood sugar. This supplement didn't replace anything, it just supports everything else I already do.
When I skip it or run out for a few days, I usually notice more variability in my post-meal numbers. I've tried other supplements before, but this is the only one that's consistently supported my numbers, especially when life gets busy or my meals aren't perfectly planned.
Why I Share This on My Blog
When I started I Hacked Diabetes, I didn't have all the answers and I still don't. But I do know what works for me, and I know how frustrating this journey can be when it feels like nothing is working.
That's why I share recipes, real-life experiences, and tools like this. Not because they're trendy, but because they've helped me feel better, more in control, and more hopeful.
Take them with your largest meal of the day to help manage post-meal blood sugar and reduce stomach discomfort.
No, they're not a replacement for medication, they can support blood sugar control but should be used alongside your doctor's guidance.
Quercetin is found in foods like onions, apples, and berries; berberine comes from certain plants like barberry but isn't typically consumed in food amounts.
Most people see results within 2-4 weeks of daily use, especially when combined with a low-carb diet and consistent tracking.
Final Thoughts
If you're living with type 2 diabetes and already eating low carb but still feel like something's missing. If you're curious about natural supplements that may support blood sugar balance, you might consider researching the berberine and quercetin combo.
Just remember: this is not a replacement for medication or medical advice. Always talk to your doctor, monitor your blood sugar, and notice how you feel. For me, it became a small habit that helped support the bigger picture.
