The level of glucose (sugar) in the blood tells us a lot about how well your body converts food into energy. When it is stable, you have more energy, you control your weight more easily and you reduce the risk of long-term metabolic problems. And when it fluctuates, the body feels it — often long before laboratory changes appear.
What is a normal blood sugar level?
Reference values can vary depending on the laboratory, but roughly:
- Fasting glucose: 3.9 – 6.1 mmol/l (normal).
- Glucose 2h after a meal: below 7.8 mmol/l.
- Values of 6.1 – 6.9 mmol/l fasting indicate prediabetes and require checking.
- Values of ≥ 7.0 mmol/l fasting in two analyses indicate diabetes.
The exact diagnosis is always made by a doctor. If you suspect a sugar problem — have a glucose and HbA1c analysis done (average blood sugar over the last 3 months).
Signs that blood sugar levels are disturbed
- Frequent thirst and dry mouth.
- Frequent urination, especially at night.
- Fatigue and sleepiness after meals.
- Strong craving for sweets.
- Blurred vision and difficulty concentrating.
- Slower wound healing and frequent infections.
How diet affects blood sugar
Choose complex carbohydrates
Whole grains, legumes, vegetables and pulses release energy gradually and do not cause a sugar spike, unlike white bread, sweets and soft drinks.
Combine carbohydrates with fibre and protein
Adding fibre (vegetables, seeds) and protein (eggs, fish, legumes) slows down sugar absorption and keeps you full longer.
Regular meals and physical activity
A regular meal rhythm and a walk after eating help muscles use glucose more efficiently. The goal is at least 150 minutes of moderate activity per week.
Natural support for normal blood sugar
Certain herbs and natural ingredients are traditionally used to support metabolic balance:
- Berberine — an active substance studied for its favourable effect on glucose metabolism.
- Cinnamon extract — may improve the sensitivity of cells to insulin.
- Chromium — a mineral involved in carbohydrate metabolism.
- Bitter melon — traditionally used to support normal blood sugar levels.
- Alpha-lipoic acid — an antioxidant that supports metabolic health.
These ingredients are often found in combined supplements for sugar regulation, such as the products from our Blood sugar category.
Frequently asked questions (FAQ)
Do sweets always cause a blood sugar spike?
Usually yes, especially if eaten alone. Foods with a high glycaemic index raise glucose faster; combining them with fibre and protein softens the spike.
When should I check my blood sugar?
The recommendation is that all adults after 45 check glucose every 3 years, and earlier if there are risk factors (obesity, family history of diabetes, physical inactivity).
Do supplements replace diabetes therapy?
No. Supplements are only support and do not replace medicines prescribed by a doctor. Do not interrupt therapy without consulting your doctor.
