I tried Gluconol as a dietary supplement to support normal blood sugar levels. I took it mainly due to fluctuations after meals and wanted more stable values after breakfast and dinner.

The box mentioned capsules, and the composition was based on cinnamon, gymnema, banaba, fenugreek, ginkgo, and astaxanthin. This made sense to me as a supportive aid to my routine, not as a replacement for food, exercise, or medication. I liked that they were capsules because I can’t stand powders in water. They were just a bit larger for me, and for the first two days, I had to wash them down with almost a whole glass of water; otherwise, I felt them in my throat.

How I took it

I stuck to a simple routine. One capsule in the morning with food and one in the evening with food. When I tried it on an empty stomach once, I felt a slight rumbling in my stomach and a strange empty feeling within an hour, so I didn’t repeat that. I managed to take it for six weeks straight.

I also had my own monitoring. At home, I occasionally measure my blood sugar, so I mainly tracked it in the morning on an empty stomach and sometimes two hours after meals when I knew I had eaten something worse. I didn’t go overboard with the diet; I just made sure not to stack sweet things on the same day. My phone alarm helped me mainly with the evening dose because I would easily forget it on weekends.

What I noticed about myself

During the first week, almost nothing happened. I didn’t feel any boost, and the readings on the meter looked similar to before. Around the third to fourth day, I noticed that I had less craving for sweets after lunch, but part of that could have been because I was eating more protein. I didn’t attach much importance to it.

In the second week, I had a few days when my numbers were calmer two hours after meals, especially after dinner. It wasn’t a miracle, more like smoothing out the spikes. I could tell even without measuring because I used to feel fatigue and a sort of heaviness after some meals. That started to happen less often, although it didn’t disappear completely.

The third and fourth weeks were the strongest for me. I felt like I was better at sticking to my routine because I wasn’t as tempted to snack between meals. When I had a classic breakfast, after which I sometimes spiked, the fluctuation wasn’t as sharp. However, the morning fasting values made less of an impression on me than I expected. I was hoping for more there. It was more about how I felt throughout the day.

By the fifth and sixth weeks, the effect was more stable. Nothing new was added, and it didn’t seem to escalate further. On days when I had a lot of carbohydrates and little movement, Gluconol didn’t save me. I say that openly.

What bothered me

  • In the first few days, I experienced slight bloating and more frequent burping, but then it subsided.
  • When I took the capsule without food, I had an unpleasant feeling in my stomach.
  • Sometimes I felt a strange warm sensation in my face about half an hour after taking it.
  • The morning fasting values didn’t improve as much as I expected.
  • Fatigue after a heavy meal didn’t disappear; it just became milder.

I was also bothered by the fact that the information on the packaging was in English. For a dietary supplement sold here, it didn’t seem very trustworthy to me. And one more small thing: the smell from the blister reminded me of cinnamon and something herbal, so when I left it open on the table, it was noticeable in the kitchen.

I considered safety as I would with a dietary supplement, not a medication. I monitored how my body reacted and didn’t add anything else to it.

Who I would recommend it to

In my opinion, Gluconol could make sense for people who deal with mild fluctuations after meals, want to stabilize their routine a bit, and are willing to give it at least three to four weeks. It’s also suitable for those who already have some measuring routine or at least are aware of how they feel after eating.

On the other hand, I would skip it if someone expects quick and significant reductions in values without changes in diet and exercise. I would approach it cautiously with a sensitive stomach because it didn’t sit well with me on an empty stomach. And if someone is already taking medication for sugar, I would take combinations seriously and discuss it with a doctor because surprises in values are not something I would want to play with.

For me, it’s not a product for high expectations, but it worked as a supportive aid. After six weeks, I would only buy it again during times when I know I will have a worse routine and want to monitor fluctuations. I don’t consider it a long-term solution or a replacement for the basics. In my case, it slightly smoothed out the spikes after meals and reduced cravings for sweets, but I didn’t see any miracles.
