Botanical Extract ThymoQuin-OCare Shown to Reduce Plaque and Support Gum Health

TriNutra has announced the publication of a new human clinical study evaluating its patented ThymoQuin-OCare for oral health support.¹ Published in the Journal of Nutrition Food Science and Technology, the research highlights significant benefits regarding plaque accumulation, gingival function, and the stabilization of the oral microbiome.²

The study addresses an interest in new oral hygiene strategies. While traditional approaches focus primarily on the mechanical removal of plaque and the targeting of harmful bacteria via brushing and flossing, the company explains, there is a growing industry interest in adjunctive solutions that manage gingival inflammation and dysbiosis. These factors are recognized as key contributors to acid formation and teeth demineralization, it adds. ThymoQuin-OCare, a black seed–derived ingredient, aims to fill this gap by suppressing microbial overgrowth and reducing acid formation while supporting gum and dental health.

Clinical Findings and Efficacy

The clinical trial evaluated the safety and effectiveness of ThymoQuin-OCare administered as an oral health lozenge over a 28-day period with 9 adult participants. Researchers tracked shifts in microbial populations alongside assessments of dental and gingival health. Clinical assessments, Gingival Index scoring, oral microbiome analysis, and questionnaires measured the changes in oral health. The results demonstrated significant improvements in both hard and soft oral tissues and the ingredient was well tolerated.

Key data points from the clinical assessment include:

• Gingival Index Reduction: The Gingival Index decreased by 14% over the course of the study
• Inflammation Management: 67% of participants showed measurable reductions in gingival inflammation
• Plaque and Bleeding: Dental plaque accumulation and gingival bleeding also demonstrated improvements

TriNutra noted that every participant in the study demonstrated at least one measurable positive outcome during the 28-day period.

Microbiome Diversity and Subjective Experience

Beyond physical tissue health, the study analyzed the oral microbiota to determine the product’s impact on microbial balance. The analysis revealed that 89% of participants experienced an increase in the Shannon Diversity Index, which measures the variety and abundance of microbial species. Notably, the lozenges promoted the growth of beneficial commensal microflora, and no pathogenic microflora growth was observed before or after the application.

The objective clinical data was mirrored by positive subjective feedback from the participants. Between 67% and 78% of subjects reported experiencing fresher, longer-lasting breath. Furthermore, 89% of participants noted visible improvements in the appearance of their gums, the cleanliness of their teeth, and their overall sense of oral wellness.

Industry Implications

This research further expands the clinical foundation for ThymoQuin-OCare and its application in the functional food and supplement space. "The oral microbiome plays a central role in maintaining gum health, immune function, and barrier integrity," stated Morris Zelkha, CEO of TriNutra. Zelkha noted that these findings suggest the ingredient supports optimal oral hygiene and a healthier mouth environment.

Additional Research on ThymoQuin

Previous research on the ThymoQuin from TriNutra has linked the black seed-derived ingredient to improved sleep and stress resilience. A randomized, placebo-controlled trial published in 2026 demonstrated statistically significant reductions in key biomarkers of stress in moderately stressed adult participants over the 8-week study period.³ Specifically, the results demonstrated a 23% reduction in cortisol levels, and a 31% increase in sleep quality.

Additionally, a study in 2022 involving endurance athletes demonstrated that supplementation with ThymoQuin over 4 weeks reduced upper respiratory tract infections and improved overall psychological wellbeing following endurance training and competition.

The bioactive compound, thymoquinone, is associated with antioxidant and anti-inflammatory activity.
