SugarStopper, studied in people for 90 days
In 2026 we asked an independent clinical research organisation to test SugarStopper in people. Thirty adults took it every day for 90 days, alongside the medicines their doctors had prescribed.
This page explains how the study was run and what it found.

Who took part
Adults aged 18 to 65 with type 2 diabetes, already on diabetes medicines that were not being changed. Their test results at the start had to fall in these ranges.

| Blood sugar 2 hours after a meal | 180 to 230 mg/dL |
Everyone who joined was taking metformin, and 26 of the 30 were also taking a second diabetes medicine. Nobody stopped or changed a medicine during the study. Everyone was asked to keep their usual food and daily routine.
Who could not join
- People with type 1 diabetes
- HbA1c above 8.5%

How the study ran
Each person came to the hospital four times over 90 days. The same tests were done for everyone, at the same points.
Before
Screening
Checked against the entry rules. Each person signed a consent form.
Day 0
Starting point
HbA1c, fasting and after meal blood sugar, quality of life questionnaire, weight, blood pressure. First capsules given.
Day 30
First check
Fasting and after meal blood sugar, blood pressure, pulse, any side effects.
Day 60
Second check
The same tests as day 30.
Day 90
Final check
All the starting tests repeated, including HbA1c and the questionnaire, plus a final side effects check.
What was measured
| Measure | What it tells you | When |
|---|---|---|
| HbA1c (the main measure) | Your average blood sugar over roughly the last 3 months | Day 0 and day 90 |
| Fasting blood sugar | Blood sugar in the morning, before eating | Every visit |
| After meal blood sugar | Blood sugar 2 hours after a meal | Every visit |
| Quality of life | The World Health Organization's questionnaire (WHOQOL-BREF), covering physical health, mood, relationships and surroundings | Day 0 and day 90 |
| Safety | Side effects, blood pressure, pulse, weight and a physical check by the doctor | Every visit |
How the results were counted
All 30 people are included in the results. Two people stopped coming to their visits before day 90, for reasons not linked to side effects. For these two, their last recorded results were used as their final results. This is a standard, cautious way to count people who leave a study early.
What the study found
Averages for all 30 people, at the start and at day 90.
| Measure | Day 0 | Day 90 | Change |
|---|---|---|---|
| HbA1c | 7.50% | 5.95% | down 1.55 points |
| Fasting blood sugar | 139 mg/dL | 98 mg/dL | down 29% |
| After meal blood sugar | 192 mg/dL | 139 mg/dL | down 28% |
| Quality of life score | 89 | 107 | up 18 points |
- 28 of the 30 people lowered their HbA1c by at least 0.5 points by day 90.
- Quality of life scores went up in all four areas of the questionnaire.
- Weight, blood pressure and pulse stayed about the same.
A fall in HbA1c from 7.50% to 5.95% is a fall of 1.55 percentage points. Bars start at zero.
Side effects
8 of the 30 people reported one side effect each. All 8 were mild.
The study doctor assessed each one and judged that none of them was caused by SugarStopper.
There were no serious side effects, and nobody stopped taking SugarStopper because of a side effect.
If something does not feel right while taking any supplement, stop and speak to your doctor.
| Side effect (all mild) | People | Caused by SugarStopper? |
|---|---|---|
| Headache | 3 | No |
| Nausea | 2 | No |
| Bloating | 2 | No |
| Gas | 1 | No |
| Total | 8 of 30 | None |
What this study can and cannot tell you
Every study has limits. These are the ones that matter here.
There was no comparison group
Nobody took a dummy capsule. So the study cannot separate how much of the change came from SugarStopper and how much from medicines, food, or the extra care people get in a study.
Everyone knew what they were taking
This is called an open label study. Knowing can change how people behave and report how they feel.
It was small and short
30 people, one hospital, 90 days.
Everyone stayed on their medicines
SugarStopper was taken with prescribed medicines, not instead of them.
The numbers are averages
Some people changed more and some less. Your own results may be different.
What it does show: in these 30 people, taking SugarStopper every day for 90 days alongside their usual medicines, average HbA1c and blood sugar readings went down. Side effects were few and mild, and the study doctor linked none of them to SugarStopper.
Questions people ask
Can I stop my diabetes medicine if I take SugarStopper?
No. Everyone in the study stayed on their medicines. Do not stop or change any medicine without your doctor.
Is SugarStopper a medicine?
No. It is a food supplement, FSSAI registered. It is meant to be taken alongside a balanced diet, regular activity and your doctor's care.
How long before I see a change?
The study measured HbA1c at 90 days. Give it at least 3 months of daily use, and check your numbers with your doctor.

About these results
Results from a 90 day, open label, single group clinical study (protocol CTSRS/2623, 2026) of 30 adults with type 2 diabetes who took SugarStopper alongside their prescribed diabetes medicines. There was no placebo group, so the improvement cannot be attributed to SugarStopper alone. Figures are study averages; individual results vary. SugarStopper is a food supplement, not a medicine. Do not stop or change prescribed medicines. Consult your doctor.
