Hi Alan, thank you for taking the time to leave this. Twelve months is a real commitment, and we are glad Diabec has become part of your daily routine. Feedback from long-term customers like you means a great deal to our small team.

It's a miracle!
I saw an ad for Diabec on Facebook so started reading reviews and after seeing how good they were I ordered it for my husband and omg this stuff is a miracle! His A1C dropped from 9 to 8.3 in four days and he only takes two a day since he dropped to low at night. His glucose levels went over 300 hundred after every meal but now it doesn't go over 230 after a big meal and drops fast! I just wonder if it's alright to drop so quickly and does it help people with type 1 diabetes? Thanks to whoever created this miracle pill!

Hi Carmen,
Thank you so much for taking the time to write this, and for the kind words about the team. We are really glad you and your husband have had such a positive experience.
We do have to add a serious note. Diabec is a food supplement made from traditional Ayurvedic herbs, formulated to support healthy blood sugar levels as part of a balanced diet and lifestyle. It is not a medicine, and it is not a substitute for medical care or for anything a doctor has prescribed, so we are not able to comment on individual readings.
On your two questions, both really need to go to your husband's doctor or diabetes nurse rather than to us. You mentioned he went low at night, and that is exactly the sort of thing his clinical team should hear about, because it can mean his prescribed medication needs reviewing. Please do not stop, reduce or change any prescribed medication without speaking to them first.
As for type 1 diabetes, that is always managed under medical supervision with insulin, so anyone with type 1 should speak to their doctor before adding any supplement.
If it helps, we are happy to send over the full ingredient list so his doctor can look through it. Just email us at support@dia-bec.com, and we will get it across to you.
Wishing you both all the best,
The Diabec Team

My Experience with Diabec
I have been very pleased with my experience using Diabec. Since incorporating it into my daily routine, I have noticed a significant improvement in my blood glucose readings and, more importantly, greater consistency in maintaining healthier levels throughout the day.
What has impressed me most is the change I have observed in my overall glucose management. My readings have become much more stable, and I feel that Diabec has been a valuable addition to the lifestyle changes I have been making with my nutrition, intermittent fasting, and overall wellness routine.
I understand that individual results can vary, and I do not consider my experience a substitute for professional medical guidance. However, based on my personal experience, I am very satisfied with the results I have seen and would continue to use Diabec as part of my overall wellness approach.

Thank you for such a considered review, Prof. Baez. We really appreciate you taking the time to describe how Diabec sits alongside your nutrition, fasting, and wider wellness routine, and we appreciate just as much that you noted individual experiences vary and that nothing replaces professional medical guidance. That is exactly the balanced approach we would want anyone to take with a supplement. If you ever have questions about the six Ayurvedic herbs in the formula, or about your orders, our team is here whenever you need us. Wishing you continued wellness. The Diabec Team

Hello, thank you for taking the time to leave feedback. We have looked carefully through our records, and we cannot find any order, account, or contact under your details. The product you describe is not one that we sell or have ever sold. Diabec offers a single Ayurvedic glucose support supplement and nothing else, so it looks like there may be a genuine mix-up with a different company that has a similar name. We would really like to help get this pointed in the right direction. Please email us at support@dia-bec.com, and we will do whatever we can to assist. Kind regards, The Diabec Team

I cannot believe what has happened to my life recently. I have been highly Diabetic since the age of 16 for 26 years. Insulin hardly works for me and metformin therefore cannot do too much on its on
Started taking this and went down from 26 MMOL to 10 MMOL

Thank you for taking the time to share such a heartfelt review, Andrew. We are genuinely moved that you have had such a positive experience, and we are grateful to have you as part of the Diabec family.
One really important note for your safety. Insulin and other diabetes medications should only ever be reduced or stopped under the direct guidance of your doctor, who can monitor your blood glucose and adjust your treatment safely. Please keep your healthcare team closely involved in any changes, even when you are feeling well, so they can support you.
On the formula, thank you for the kind words. We are always committed to our quality and consistency.
Wishing you continued good health, and thank you again for sharing your story.

FIABEC you have done it again 2026
FIABEC you have done it again 2026. I had reason to contact Customer Care because I was experiencing Hipos (my readings were 2.0 on several times. I was taking only 3 Capsules a day after eating. Customer Care suggested 2 aday but changed how I took them. That was over 2 weeks ago but I now only take 1 in the morning. By doing regular checks, I now have a snack between 3 & 4pn to avoid Hypos. I read many reviews saying Diabec reverses Diabetes and in my case it seems I'm well on the way. My GP after my last AC1 test I was going something right. The best thing I did was to stop taking Metformen and I couldn't be happier with DIABEC. I'm about to cancel my next delivery thanks to only needing 1 a day. Not sorry.
❤️🥰🙏can I add, my GP is aware of my progress and is aware I stopped my Metformen TWO years ago. Also that my readings are bow totally normal with No Hypos at all for quite some time. ❤️🥰🙏

Judy, thank you for this detailed update and for your patience in reaching out to our Customer Care team. A reading of 2.0 mmol/L sits well below the ADA's recommended fasting blood glucose target of 4.0 to 7.0 mmol/L, and we are glad the team was able to help you adjust both your timing and dosage to stabilise those levels. Hearing that your HbA1c is now trending positively is exactly the outcome Diabec's glucose support formula is designed to support.
Diabec's formulation, including berberine, cinnamon bark extract, and chromium, works to support healthy glucose levels by improving insulin sensitivity and moderating post-meal glucose variation. Your approach of one capsule in the morning with a strategic mid-afternoon snack shows excellent self-management and a real understanding of your body's response.
We want to be clear about something important: Diabec is a natural blood sugar support supplement, not a replacement for prescribed medication or insulin. We are genuinely pleased your GP is actively monitoring your progress. We always strongly recommend that any changes to medication dosage, type, or frequency, including Metformin, be made only under the direct supervision of a qualified healthcare professional. Blood sugar management is highly individual, and your doctor is best placed to guide any treatment adjustments. Please do not stop or reduce any prescribed medication without consulting your doctor first. We care deeply about your long-term health and safety.
Thank you for your loyalty and for trusting Diabec as part of your health journey. Continue working closely with your GP, and reach out to our Customer Care team anytime.

Diabec is a wonder supplement
Diabec is a wonder supplement. All this while I have used all kinds of medication and gone through all kinds of diets with no result, but under 48 hours after I started Diabec, my sugar level crashed and almost went below normal, so I had to cut all other medications temporarily.

Reply from Diabec
Thanks for the kind words, Gbenga. One thing matters more than anything else here though: please do not cut your other medication on your own, even for a short while. A sudden drop like the one you describe is exactly what your doctor needs to hear about, so they can check your levels and tell you what is safe for you. Diabec is a food supplement, not a replacement for the medication your doctor put you on. Have that chat with them first, and take care of yourself.

Keep them in the loop so they can keep an eye on your numbers. Thanks again for staying with us this long.

Thank you, Grace - we're delighted to hear Diabec has been helpful for you.
Consistency matters, and it sounds like you've found a routine that works. We take the formulation seriously: berberine, cinnamon bark extract, chromium, and alpha-lipoic acid, each chosen for the strength of the evidence behind it.
We'd love to hear how your experience develops. How long have you been taking Diabec?

Mick, glad to hear you're seeing results in the first few days.
The berberine and chromium in Diabec are both well-researched ingredients. Berberine has been the subject of extensive clinical investigation, and chromium plays a key role in supporting normal macronutrient metabolism.
Keep tracking your numbers and let us know how things develop over the coming weeks. What changes have you made alongside taking Diabec?

Hi Gbenga,
Thank you so much for taking the time to share your experience with Diabec. It genuinely means a lot to our small team.
A friendly note from us: a fasting reading of 3.8 mmol/L is at the lower end of the normal range, so please do stay in close contact with your GP and keep monitoring regularly, especially in the first weeks. Diabec is a 6-herb Ayurvedic food supplement (not a medicine), best used alongside a balanced diet, hydration, and movement. Any changes to prescribed medication should always be discussed with your doctor, who knows your full clinical picture.
If you'd like personalised guidance on how to fit Diabec into your daily routine, our care team is one message away at support@dia-bec.com or via WhatsApp.
Wishing you continued well-being.
