Gram Research analysis shows that scientists have successfully standardized how 150 Mediterranean plant-based dietary supplements are classified and labeled using international coding systems. This standardization makes supplement labels clearer and more honest, helping consumers know exactly what they’re buying and allowing doctors and manufacturers to communicate more reliably about supplement contents and safety.
Mediterranean plants have been used for thousands of years to treat illnesses and keep people healthy. Today, these plants are turned into dietary supplements that millions of people take. However, there’s a problem: different countries and companies classify and label these supplements differently, making it hard to know exactly what you’re getting. Researchers just completed a major project coding 150 Mediterranean plant-based supplements using standardized systems to create a reliable database. This work helps manufacturers, doctors, and consumers understand exactly what’s in these supplements, making them safer and more trustworthy to use.
Key Statistics
A 2026 research project coded 150 Mediterranean plant-based dietary supplements using LanguaL™ and FoodEx2 standardized classification systems to create a reliable, transparent database of supplement ingredients and bioactive compounds.
Mediterranean plant supplements contain three main types of bioactive compounds—alkaloids, polyphenols, and terpenes—that offer therapeutic benefits, according to research reviewed by Gram on standardized supplement classification.
Standardized coding of dietary supplements improves data interoperability, allowing manufacturers, health professionals, and consumers to access consistent, transparent information about supplement contents across different countries and brands.
Continuous updates to standardized supplement databases are crucial for managing comprehensive information and supporting informed decision-making about Mediterranean plant-based health products, according to 2026 research on supplement classification systems.
The Quick Take

- Who participated: Researchers analyzed 150 different dietary supplements containing Mediterranean plants like oregano, thyme, and olive leaf that are sold as health products
- Key finding: Using two standardized coding systems (LanguaL™ and FoodEx2), scientists successfully classified all 150 supplements, creating a reliable database that makes supplement information consistent and transparent across different countries
- What it means for you: When you buy a Mediterranean plant supplement, standardized coding means the label will be clearer and more honest about what’s actually inside. This helps you make better choices about which supplements to buy and use
The Research Details
This research project focused on organizing and standardizing information about 150 dietary supplements made from Mediterranean medicinal plants. The scientists used two main classification systems—LanguaL™ and FoodEx2—which are the international gold standards for describing food and supplement ingredients. Think of it like creating a universal language so that a supplement labeled in Italy means the same thing as one labeled in France or Germany.
The researchers carefully coded each of the 150 supplements, documenting their ingredients, the plant sources, and the bioactive compounds (the parts that actually do something in your body) they contain. These compounds include alkaloids, polyphenols, and terpenes—natural chemicals found in Mediterranean plants that have been shown to have health benefits.
The goal was to update the Italian Dietary Supplement Label Database with accurate, standardized information. This makes it easier for manufacturers to label products correctly, helps doctors recommend safe supplements to patients, and gives consumers confidence that they’re buying what the label says they’re buying.
Right now, dietary supplements are labeled differently in different countries, which creates confusion. A supplement that says it contains ‘Mediterranean herb blend’ in one country might be labeled completely differently elsewhere. This standardization project matters because it creates a common language that everyone—from manufacturers to doctors to shoppers—can understand. When information is standardized, it’s easier to track which supplements are safe, which ones work, and which ones might cause problems.
This research represents an important organizational and classification effort rather than a traditional scientific experiment. The strength of this work lies in its systematic approach to standardizing 150 real-world supplements using internationally recognized coding systems. The use of LanguaL™ and FoodEx2—the main classification systems used globally—ensures the results are reliable and can be used across different countries. The work is strengthened by its focus on updating an actual database (the Italian Dietary Supplement Label Database) that will be used by real people making real decisions about supplements.
What the Results Show
The research team successfully classified all 150 Mediterranean plant-based dietary supplements using the LanguaL™ and FoodEx2 coding systems. This comprehensive coding project created a standardized database that clearly identifies what’s in each supplement, including the specific plants used and the active compounds they contain.
The supplements studied contained Mediterranean plants rich in bioactive compounds—natural chemicals that have therapeutic benefits. These compounds include alkaloids (found in plants like berberine-containing species), polyphenols (found in olive, grape, and green tea), and terpenes (found in herbs like oregano and thyme). By standardizing how these supplements are coded and described, the researchers made it possible to compare supplements across different countries and manufacturers.
The standardized coding system now allows health professionals, manufacturers, and consumers to access consistent, transparent information about what’s actually in these supplements. This is crucial because it means a supplement labeled in Italy will have the same clear description as one labeled in Spain or Greece, reducing confusion and improving safety.
The research highlighted the importance of continuous database updates for managing supplement information. As new supplements are developed and existing ones are reformulated, the database needs to stay current. The standardized coding system also makes it easier to conduct scientific research on these supplements because researchers can now reliably identify which supplements contain which ingredients. Additionally, the work demonstrates that accurate classification supports ‘data interoperability’—meaning different computer systems and databases can now share and understand supplement information without confusion.
Mediterranean medicinal plants have been used for centuries, and modern research has confirmed that many of them contain compounds with real health benefits. However, previous efforts to classify and standardize these supplements have been inconsistent and fragmented. This research builds on decades of work in food and supplement classification by applying the most current international standards (LanguaL™ and FoodEx2) specifically to Mediterranean plant supplements. It represents a significant step forward in bringing order and transparency to a market that has historically lacked standardization.
This research focuses on classification and coding rather than testing whether the supplements actually work or are safe. The study analyzed 150 supplements, which represents a good sample but doesn’t cover every Mediterranean plant supplement on the market. The research also depends on accurate information from manufacturers about what’s in their products—if a company mislabels a supplement, the coding system can only work with the information provided. Additionally, while standardized coding improves transparency, it doesn’t guarantee that all supplements are equally effective or safe; that requires separate safety and effectiveness testing.
The Bottom Line
If you use Mediterranean plant-based dietary supplements, look for products from manufacturers who follow standardized labeling practices. When buying supplements, check the label carefully to see if it clearly lists the specific plants and their amounts. Talk to your doctor or pharmacist before starting any new supplement, especially if you take medications. The standardized coding system helps ensure transparency, but it’s not a guarantee of safety or effectiveness—those require separate scientific testing. Confidence level: High for improving transparency and safety; moderate for determining actual health benefits without additional research.
This research matters most to people who take Mediterranean plant supplements, manufacturers who make these products, pharmacists and doctors who recommend supplements, and health agencies that regulate supplements. If you buy supplements at health food stores, pharmacies, or online, this standardization effort helps protect you by making labels clearer and more honest. People with chronic health conditions who use supplements should especially pay attention, as accurate labeling helps prevent dangerous interactions with medications.
The benefits of standardized coding appear immediately—you should notice clearer, more consistent labeling on supplement bottles right away as manufacturers adopt these standards. However, it will take time for all manufacturers to update their labeling and for the database to become widely used. Over the next 1-2 years, you can expect to see more consistent supplement information across different brands and countries. The long-term benefit is that as more data accumulates in the standardized database, scientists will be able to better study which supplements actually work and which ones are safest.
