Sugar in energy drinks – the underestimated problem

Sugar in energy drinks – the underestimated problem

If you open a standard energy drink can, you'll often find an inconspicuous line on the back: 27g of sugar per can. That sounds abstract – but in reality, it's almost seven teaspoons of pure sugar at once. The effects of that on your body are well-researched – and anything but harmless.

What sugar triggers in the body

After consuming a sugary drink, blood sugar levels spike within minutes. The pancreas reacts with a massive release of insulin – and blood sugar drops just as quickly as it rose. The result: the infamous "sugar crash." Fatigue, difficulty concentrating, irritability, and renewed sugar cravings set in – a cycle that can repeat itself throughout the day.

•         Insulin resistance: Those who experience this cycle daily train their bodies in the long term to respond less well to insulin – a key risk factor for type 2 diabetes and metabolic syndrome.

•         Pro-inflammatory: High sugar intake activates pro-inflammatory signaling pathways in the body. Chronic low-grade inflammation is now considered a contributing factor to cardiovascular disease, obesity, and even neurodegenerative processes.

•         Negative effects on the brain: Sugar affects dopamine release similarly to addictive substances – providing short-term rewards but leading to long-term exhaustion. Studies show that high sugar consumption can impair memory, learning ability, and mood stability.

•         Empty calories, no nutritional value: Sugar provides energy without a single micronutrient. Those who use energy drinks as a performance booster get a short-term boost – and pay the price with a subsequent performance crash.

Why Neuroblends is taking a different approach

At Neuroblends, we consistently rely on stevia as a natural sweetener – and this is not a marketing decision, but a matter of integrity towards our customers.

•         No blood sugar spike: Steviol glycosides – the sweeteners from the stevia plant – have a glycemic index of zero. They do not trigger an insulin response, no energy slump, no sugar crash. Energy levels remain stable, as does focus.

•         Calorie-free, but not uncompromising: Stevia sweetens without calories – but unlike artificial sweeteners such as aspartame or sucralose, it is a plant-based natural substance that has been used in South America for centuries and is considered one of the best-researched plant-based sweeteners worldwide.

•         No impact on the microbiome: Artificial sweeteners like sucralose are suspected of negatively affecting the gut microbiome. Stevia, on the other hand, shows prebiotic properties in studies – it can even support the growth of healthy gut bacteria.

•         Well-tolerated and safe: Steviol glycosides are classified as safe by the EFSA and FDA and are suitable for all population groups – including diabetics and people who avoid sugar for health reasons.
