Why care about blood sugar and glucose metabolism?
Unstable blood sugar can lead to fatigue, sugar cravings, and eventually to insulin resistance. According to expert reviews, targeted supplements – especially berberine, chromium, and inositol – may help improve insulin sensitivity and support glycemic control.
Disrupted glucose balance may also cause weight gain and fatigue. In addition to traditional actives like berberine, chromium, or inositol, we also include modern, multifunctional ingredients – such as fisetin.
What will you find in this category?
- Berberine – activates AMPK, supports fat metabolism and glycemia.
- Chromium (GTF) – essential for insulin sensitivity and carbohydrate processing.
- Gymnema sylvestre – helps reduce sugar cravings and stabilize blood sugar levels.
- Myo- & D-chiro inositol – popular for PCOS and among biohackers to improve glucose transport.
- Fisetin – a natural flavonoid with anti-inflammatory and senolytic effects, may contribute to metabolic balance and improved insulin sensitivity.
How we choose our products
We carefully select every product – preferring clean-label formulas, direct sourcing from manufacturers and evidence-backed effects. We focus on brands with strong reputations, authentic reviews and, where possible, available clinical studies. We’re the exclusive importer of most brands at www.pravebio.cz, and we personally use everything we sell.
Tips for optimal results
- Take berberine with meals 2–3× daily (effects typically appear after 4–6 weeks).
- Chromium is most effective when taken with your highest-carb meal of the day.
- Combine with probiotics to support the microbiome here – gut health plays a key role in blood sugar control.
FAQ
▶ What is the recommended dosage of berberine and when should I take it?
The most common dosage is 500 mg three times a day, taken 30 minutes before meals. This improves absorption and minimizes digestive discomfort. First results are typically seen after 4–6 weeks of regular use.
▶ How long does it take for berberine to lower blood sugar?
Clinical studies show a noticeable reduction in fasting glucose typically after 4–6 weeks; for some individuals even earlier, depending on diet and lifestyle.
▶ Can I take berberine with metformin or other antidiabetic drugs?
Combination is possible, but only under medical supervision – concurrent use may increase the risk of hypoglycemia. Dosage must be adjusted individually.
▶ Are there any side effects of berberine?
The most common are mild digestive issues (bloating, diarrhea). These usually subside after a few days; starting with a lower dose and taking it with food can help.
▶ How does chromium improve insulin sensitivity and what is a safe dose?
Chromium (preferably GTF or picolinate) enhances insulin efficiency at the cellular level. Standard supplements contain 200–1000 µg daily; higher doses should be used only with medical guidance.
▶ Does myo- & D-chiro inositol help with PCOS?
Yes, the 40:1 ratio (myo to D-chiro) has shown benefits in improving ovulation, reducing androgens, and enhancing insulin sensitivity in PCOS.
▶ How does gymnema reduce sugar cravings and when to take it?
Gymnemic acids block sweet taste receptors and slow glucose absorption. Take 10–15 minutes before consuming sweets.
▶ Can I combine these supplements and what are their synergies?
Berberine + chromium have an additive effect on glucose levels; inositol supports hormonal balance in PCOS; gymnema curbs acute cravings. Introduce one by one and monitor blood sugar.
▶ Who should consult a doctor before using these supplements?
Pregnant or breastfeeding women, people with liver or kidney disease, and those taking antidiabetic or anticoagulant medications should always consult a healthcare professional first.
Disclaimer: Food supplements are not a substitute for a varied diet. If you are pregnant, breastfeeding or taking medication, consult your doctor before use.
