According to Gram Research analysis, eating gochujang, a traditional Korean fermented red pepper paste, reduced menopause symptoms by 10-15% in an 8-week study of 59 postmenopausal women. All three gochujang formulations tested significantly decreased hot flashes, night sweats, and mood-related symptoms, with women also experiencing decreases in body fat. However, researchers note that a placebo-controlled study is needed to confirm these benefits work better than expectation alone.
A new study tested whether gochujang, a traditional Korean fermented food made from red peppers and soybeans, could help women manage menopause symptoms like hot flashes and mood changes. Researchers gave 59 postmenopausal women different versions of gochujang for 8 weeks and tracked their symptoms. All three versions significantly reduced menopause symptoms by about 10-15%, and women also lost body fat. The study shows gochujang is safe and well-tolerated, though researchers note a placebo group would strengthen future studies to confirm these benefits.
Key Statistics
A randomized controlled trial of 59 postmenopausal women published in Frontiers in Nutrition in 2026 found that consuming gochujang for 8 weeks reduced menopause symptom scores by 3.4 to 4.1 points across all three formulations tested.
In the 8-week gochujang trial, the high-microorganism formulation reduced menopause symptoms by 3.65 points (95% confidence interval -4.97 to -2.33), with all reductions statistically significant at p less than 0.0001.
All three gochujang formulations in the 2026 study produced significant reductions in menopause symptoms with no adverse events reported, demonstrating that the fermented Korean food is safe and well-tolerated in postmenopausal women.
The 8-week trial showed that percent body fat decreased across all gochujang groups, and fecal short-chain fatty acid concentrations declined in all participants, indicating changes in gut bacteria composition.
The Quick Take
- What they studied: Whether eating gochujang, a spicy Korean fermented paste, could reduce hot flashes, night sweats, and other menopause symptoms in women
- Who participated: 59 postmenopausal women with moderate to severe menopause symptoms, divided into three groups that each received a different version of gochujang for 8 weeks
- Key finding: All three gochujang formulations reduced menopause symptom scores by 10-15% after 8 weeks, with no major differences between the versions. Women also experienced decreases in body fat percentage
- What it means for you: Eating gochujang may help ease menopause symptoms like hot flashes and mood swings as a food-based option. However, more research with a control group is needed to confirm these benefits work better than placebo
The Research Details
This was a randomized controlled trial, which is one of the strongest types of research studies. Researchers randomly assigned 59 postmenopausal women to eat one of three different gochujang formulations for 8 weeks. The study was double-blind, meaning neither the women nor the researchers knew which version each person was eating until the study ended. This prevents bias from affecting the results.
The three versions differed in their microbial content, or the beneficial bacteria they contained. One version had high levels of microorganisms (HTG), one had low levels (LTG), and one was commercial gochujang (CG) as a comparison. All women had moderate to severe menopause symptoms at the start, measured using a standard symptom scale called the Kupperman Menopausal Index.
Researchers measured menopause symptoms, body composition, gut bacteria changes, and safety throughout the 8-week period. They also looked at short-chain fatty acids, which are beneficial compounds produced by gut bacteria.
This research approach is important because it tests whether gochujang actually works for menopause symptoms in a controlled way. By comparing different formulations, researchers could see if the specific bacteria content mattered. The double-blind design prevents expectations from influencing results. However, the study had one limitation: all women received active gochujang without a placebo group, so researchers couldn’t definitively prove the benefits came from gochujang itself rather than placebo effect.
This study has several strengths: it was randomized and double-blind, which reduces bias; it tracked multiple health markers beyond just symptoms; and it monitored safety carefully with no adverse events reported. The study was published in Frontiers in Nutrition, a peer-reviewed journal. The main limitation is the lack of a placebo control group, which means we cannot be certain the symptom improvements came from gochujang rather than from expectation or other factors. The sample size of 59 women is moderate but adequate for detecting differences between groups.
What the Results Show
All three gochujang formulations produced significant reductions in menopause symptoms. The high-microorganism version reduced symptom scores by 3.65 points, the low-microorganism version by 4.10 points, and the commercial version by 3.42 points. These reductions were all statistically significant, meaning they were unlikely to occur by chance. However, there were no meaningful differences between the three formulations, suggesting that the specific bacteria content did not matter for symptom relief.
Beyond menopause symptoms, women in all three groups experienced decreases in body fat percentage, which is an additional health benefit. The study found that gut bacteria composition shifted in all groups after 8 weeks of gochujang consumption, indicating that the fermented food was changing the microbial community in the digestive system.
Fecal short-chain fatty acids, which are beneficial compounds produced by gut bacteria, actually declined in all groups. This was unexpected and suggests that while gochujang changes the gut microbiota, the relationship between these changes and symptom improvement is complex and not fully understood.
Body composition improved across all groups, with decreases in body fat percentage being the most notable change. Metabolic biomarkers were measured but detailed results were not emphasized in the primary report. The study found no adverse events or safety concerns across all three formulations, indicating that gochujang is well-tolerated by postmenopausal women. This is important because it suggests the food is safe for this population to consume.
This is the first randomized controlled trial testing gochujang for menopause symptoms in humans. Previous research has shown that gochujang contains isoflavone aglycones, which are plant compounds similar to estrogen, and capsaicinoids, which are the compounds that make peppers spicy. Both of these have biological properties that could theoretically help with menopause symptoms. This study provides the first direct evidence that eating gochujang may actually help, though the mechanism is not yet clear.
The study had several important limitations. First, all participants received active gochujang without a placebo control group, so we cannot determine whether the symptom improvements came from gochujang itself or from placebo effect and expectation. Second, the study only lasted 8 weeks, so we don’t know if benefits persist over longer periods. Third, the sample size of 59 women is relatively small, which limits how broadly we can apply the findings. Fourth, the exploratory analyses of gut microbiota and short-chain fatty acids did not show clear differences between formulations, suggesting the mechanism by which gochujang helps is still unknown.
The Bottom Line
Based on this research, postmenopausal women with moderate to severe symptoms may consider adding gochujang to their diet as a potential food-based approach to symptom management. However, confidence in this recommendation is moderate because the study lacked a placebo control. Women should discuss this with their healthcare provider, especially if they are taking other medications or have digestive sensitivities. This should not replace medical treatment for severe symptoms without consulting a doctor
Postmenopausal women experiencing hot flashes, night sweats, mood changes, or other menopause symptoms should find this research relevant, particularly those seeking non-hormonal, food-based options. Women who enjoy spicy foods or have Korean cuisine in their diet may find gochujang an appealing option. This research is less relevant for women without menopause symptoms or those who prefer pharmaceutical interventions. Men and premenopausal women would not benefit from this specific finding
In this study, symptom improvements appeared within 8 weeks of regular gochujang consumption. However, individual results likely vary. Some women may notice benefits within 2 to 4 weeks, while others may need the full 8 weeks or longer. Consistency matters: the women in this study consumed gochujang regularly throughout the trial. Benefits may continue to improve with longer-term use, though this has not been tested
