A 2026 randomized controlled trial of 70 healthy adults found that a red okra and Diospyros lotus supplement increased fecal fat excretion by 55% after just 2 days of use. According to Gram Research analysis, participants taking 1.5 grams daily passed significantly more dietary fat in their stool compared to placebo, suggesting the supplement binds to fat and prevents absorption. However, the study lasted only 2 days, so long-term effectiveness remains unknown.
Researchers tested a natural supplement made from red okra and a fruit called Diospyros lotus to see if it could help your body get rid of more fat. In a study with 70 healthy adults, people who took the supplement for just 2 days while eating a controlled diet passed significantly more fat in their stool compared to those taking a placebo. According to Gram Research analysis, the supplement appeared to work by binding to dietary fat and preventing your body from absorbing it, which could help with weight management. The supplement was safe and didn’t cause any harmful side effects during the short study period.
Key Statistics
A 2026 randomized controlled trial of 70 healthy adults found that the red okra and Diospyros lotus supplement increased wet fecal fat excretion from 18.54 mg/g in the placebo group to 28.65 mg/g in the supplement group—a 55% increase after 2 days.
According to research reviewed by Gram, participants taking the botanical supplement passed nearly 80% more total fat mass (3,238 mg versus 1,802 mg) compared to placebo over a 2-day period while eating a controlled 130-150 gram daily fat diet.
In the 2026 trial, dry fecal fat measurements showed the supplement group excreted 58.39 mg/g compared to 39.54 mg/g in placebo—a 48% increase—demonstrating consistent fat-binding effects across different measurement methods.
The supplement produced these fat-excretion results without causing any reported safety concerns or changes to stool properties during the 2-day study period in 70 healthy adults.
The Quick Take
- What they studied: Whether a botanical supplement made from red okra and Diospyros lotus fruit could increase the amount of fat your body eliminates through stool
- Who participated: 70 healthy adults (34 received the supplement, 36 received placebo) who ate a controlled diet containing about 130-150 grams of fat per day for 2 days
- Key finding: People taking the supplement passed 55% more fat in their stool (measured in wet weight) compared to the placebo group after just 2 days
- What it means for you: This supplement may help reduce how much dietary fat your body absorbs, potentially supporting weight management efforts. However, this was a very short 2-day study, so longer-term effects remain unknown. Talk to your doctor before trying any new supplement.
The Research Details
This was a randomized, double-blind, placebo-controlled trial, which is considered the gold standard for testing whether something actually works. Researchers randomly divided 70 healthy adults into two groups: one received 1.5 grams per day of the red okra and Diospyros lotus supplement (called RODL), while the other received a placebo (fake pill) that looked identical. Neither the participants nor the researchers knew who was getting the real supplement until after the study ended, which prevents bias from affecting the results.
Participants ate a carefully controlled diet containing 130-150 grams of fat daily for 2 days. Researchers collected stool samples before and after the 2-day period to measure how much fat was being eliminated from the body. They also measured blood lipid levels and free fatty acids to see if the supplement affected how the body processed fats.
The researchers used standard statistical methods to compare the two groups and determine whether differences were statistically significant (meaning they weren’t likely due to chance).
This study design is important because it tests whether the supplement actually works in real humans under controlled conditions. Previous research had only tested the supplement in laboratory settings, not in people. By controlling the diet and using a placebo comparison group, researchers could isolate the supplement’s effects from other factors that might influence fat excretion.
This study has several strengths: it was randomized (reducing selection bias), double-blind (preventing expectation bias), and placebo-controlled (providing a fair comparison). The sample size of 70 participants is reasonable for this type of study. However, the study lasted only 2 days, which is very short and doesn’t tell us about long-term effects or safety. The study also only included healthy adults, so results may not apply to people with obesity or other health conditions.
What the Results Show
After 2 days of taking the supplement, the RODL group showed significantly higher fecal fat excretion compared to placebo across all measurements. In wet stool samples, the supplement group excreted 28.65 mg of fat per gram compared to 18.54 mg in the placebo group—a difference of about 55%. When measuring dry stool weight (removing water), the difference was even more dramatic: 58.39 mg versus 39.54 mg, representing a 48% increase.
When researchers measured total fat mass eliminated, the supplement group passed 3,238 mg of fat compared to 1,802 mg in the placebo group—nearly 80% more fat. All of these differences were statistically significant, meaning they were very unlikely to have occurred by chance.
Importantly, the supplement didn’t change the physical properties of stool or cause any safety concerns during the 2-day study period. Blood lipid profiles and free fatty acid levels were also measured, though the abstract doesn’t detail these results.
The study confirmed that the supplement worked specifically through fat-binding mechanisms—it grabbed onto dietary fat and prevented the body from absorbing it, rather than working through other pathways. The fact that stool properties remained normal suggests the supplement didn’t cause digestive distress or abnormal bowel movements. The safety profile appeared clean with no reported adverse effects during the study period.
Previous laboratory studies had suggested this botanical combination could block fat absorption and boost fat metabolism in fat cells, but this was the first human study to confirm these effects actually occur in real people eating normal diets. The results align with how similar fat-binding supplements (like chitosan) work, but this botanical approach appears to be more effective based on the magnitude of fat excretion increases observed.
The biggest limitation is that this study lasted only 2 days, which is far too short to determine whether the supplement would work long-term or whether people would continue to see benefits after weeks or months. We don’t know if the body adapts to the supplement over time. The study only included healthy adults, so we can’t say whether it would work for people with obesity or metabolic disorders. The study also used a relatively high-fat controlled diet (130-150g daily), which is higher than typical recommendations, so results may differ with normal eating patterns. Finally, we don’t have information about whether the supplement would work as well in real-world conditions where people eat varied diets rather than controlled meals.
The Bottom Line
Based on this single 2-day study, the supplement appears safe and does increase fecal fat excretion. However, evidence is still limited. If you’re interested in trying this supplement for weight management, discuss it with your doctor first, especially if you take medications or have digestive conditions. Don’t rely on it as your only weight management strategy—combine it with healthy eating and exercise. Confidence level: Low to Moderate (based on short study duration).
This research may be relevant for people interested in natural approaches to weight management or those looking to reduce dietary fat absorption. However, it’s not appropriate for people with certain digestive disorders, those taking fat-soluble medications (like some vitamins), or pregnant/nursing women without medical supervision. More research is needed before recommending it broadly.
This study only measured effects over 2 days, so we don’t know how long benefits last or when you might notice changes. Real-world weight management typically takes weeks to months to become noticeable. Don’t expect dramatic results from a supplement alone—it works best combined with diet and lifestyle changes.
Frequently Asked Questions
Does the red okra and Diospyros lotus supplement actually help you lose weight?
This 2-day study shows it increases fat excretion by 55%, but that’s too short to prove weight loss. Long-term studies are needed. The supplement may help reduce fat absorption when combined with diet and exercise, but shouldn’t be your only weight management strategy.
How long do you need to take this supplement to see results?
This study only tested 2 days, so we don’t know. Real weight management typically takes 4-6 weeks to become noticeable. Don’t expect immediate results. Combine the supplement with healthy eating and exercise for best outcomes.
Is the red okra supplement safe to take every day?
The 2-day study found no safety issues, but longer-term safety data doesn’t exist yet. Talk to your doctor before taking it daily, especially if you take medications or have digestive problems. It may interfere with absorption of fat-soluble vitamins.
Can this supplement replace diet and exercise for weight loss?
No. This supplement works by blocking some dietary fat absorption, but it’s not a substitute for healthy eating and physical activity. It’s best used as one tool alongside lifestyle changes, not as a replacement for them.
Who shouldn’t take the red okra and Diospyros lotus supplement?
Avoid it if you’re pregnant, nursing, take fat-soluble medications (vitamins A, D, E, K), have digestive disorders, or are allergic to okra or Diospyros lotus. Always consult your doctor before starting any new supplement.
