Eriodictyol Benefits Explained

Eriodictyol Benefits Explained An Exhaustive Deep Dive into This Powerful Citrus Flavanone

Eriodictyol, a lesser-known but increasingly studied natural compound, is a flavanone found predominantly in citrus fruits (especially lemons and oranges) and the Californian native plant Yerba Santa ( Eriodictyon californicum), from which it derives its name. As research into the vast potential of plant-derived bioactives accelerates, Eriodictyol is emerging from the shadow of more famous flavonoids like Quercetin, Hesperidin, and Naringenin, revealing a spectrum of impressive health-promoting properties. This article aims to provide a comprehensive, in-depth exploration of the known benefits of Eriodictyol, delving into the scientific mechanisms and offering fresh perspectives on its therapeutic potential as a dietary supplement. Going far beyond typical summaries, we will uncover the multifaceted ways this molecule interacts with our biology to support health and combat disease.

Understanding Eriodictyol Source, Structure, and Bioavailability Basics

Before diving into its benefits, it’s crucial to understand what Eriodictyol is and how it behaves in the body. Chemically, Eriodictyol is a flavanone, a type of flavonoid characterized by a specific structure featuring a ketone group. Its chemical formula is C₁₅H₁₂O₆. It is structurally similar to Hesperetin and Naringenin, differing only in the hydroxylation pattern on the B-ring. This seemingly small difference can significantly impact its biological activity, solubility, and metabolism. Eriodictyol exists in nature primarily in its aglycone form (the form without an attached sugar molecule) or as glycosides (with sugars). The aglycone form is less soluble in water but generally considered more easily absorbed in the gut after enzymatic cleavage of the sugar moiety by gut bacteria or enzymes in the small intestine. However, like many flavonoids, Eriodictyol’s bioavailability can be a limiting factor for its systemic effects. Absorption can be influenced by factors such as food matrix, gut microbiota composition, and individual metabolic differences. Once absorbed, Eriodictyol undergoes extensive metabolism in the liver and gut, primarily through methylation, glucuronidation, and sulfation, resulting in various conjugated metabolites that circulate in the bloodstream and are eventually excreted. While the aglycone form is often the focus of in vitro studies, it’s the circulating metabolites that exert many of the in vivo effects, and understanding their biological activity is key to appreciating Eriodictyol’s full potential.

Eriodictyol’s Powerful Antioxidant Properties Scavenging Free Radicals and Combating Oxidative Stress

One of the most well-established benefits of Eriodictyol lies in its potent antioxidant capacity. Oxidative stress, caused by an imbalance between the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) and the body’s ability to neutralize them, is implicated in the pathogenesis of numerous chronic diseases, including cardiovascular disorders, neurodegenerative diseases, metabolic syndrome, and cancer. Eriodictyol tackles oxidative stress through multiple mechanisms

1. Direct Free Radical Scavenging: Eriodictyol’s chemical structure, particularly the arrangement of hydroxyl groups on its rings, allows it to donate hydrogen atoms or electrons to stabilize highly reactive free radicals like superoxide anion (O₂⁻•), hydroxyl radical (•OH), peroxyl radical (ROO•), and peroxynitrite (ONOO⁻). This direct scavenging prevents these radicals from damaging cellular components like lipids, proteins, and DNA.
2. Metal Ion Chelation: Transition metal ions, such as iron and copper, can catalyze the formation of highly damaging free radicals (e.g, via the Fenton reaction). Eriodictyol possesses the ability to chelate (bind to) these metal ions, thereby preventing them from initiating or propagating oxidative chain reactions.
3. Upregulation of Endogenous Antioxidant Enzymes: Beyond direct scavenging, Eriodictyol can influence the body’s own antioxidant defense system. Studies indicate it can activate signaling pathways, such as the Nrf2-Keap1 pathway, which is a master regulator of cellular antioxidant responses. Activation of Nrf2 leads to the increased expression of crucial endogenous antioxidant enzymes like Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), and enzymes involved in glutathione synthesis. By bolstering these internal defenses, Eriodictyol enhances the cell’s capacity to handle oxidative insults more effectively and sustainably.
4. Protection Against Lipid Peroxidation: Eriodictyol is particularly effective at inhibiting lipid peroxidation, the oxidative degradation of lipids. This process damages cell membranes and is a key event in the development of atherosclerosis and other diseases. By scavenging peroxyl radicals and chelating metals, Eriodictyol helps preserve cell membrane integrity and function. This robust antioxidant activity forms the foundation for many of Eriodictyol’s other reported benefits, as oxidative stress is a common underlying factor in inflammation and various chronic diseases.

Eriodictyol as an Anti-Inflammatory Champion Modulating Immune Responses and Inflammatory Pathways

Chronic inflammation is another major contributor to the development and progression of modern diseases. Eriodictyol demonstrates significant anti-inflammatory properties, acting through various mechanisms to dampen excessive inflammatory responses

1. Inhibition of Pro-inflammatory Mediators: Eriodictyol has been shown to suppress the production and release of key pro-inflammatory cytokines and chemokines, such as Tumor Necrosis Factor-alpha (TNF-α), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6), and Monocyte Chemoattractant Protein-1 (MCP-1). These molecules are central players in initiating and propagating inflammatory cascades.
2. Modulation of Key Signaling Pathways: A major mechanism underlying Eriodictyol’s anti-inflammatory effects is its ability to modulate critical intracellular signaling pathways involved in inflammation. It can inhibit the activation and translocation of Nuclear Factor-kappa B (NF-κB), a master transcription factor that regulates the expression of numerous pro-inflammatory genes (including those for cytokines, chemokines, and enzymes like COX-2 and iNOS). By blocking NF-κB activation, Eriodictyol effectively shuts down the inflammatory gene expression program. It can also influence other pathways like the Mitogen-Activated Protein Kinase (MAPK) pathways (ERK, JNK, p38), which are involved in transmitting inflammatory signals.
3. Suppression of Inflammatory Enzymes: Eriodictyol can inhibit the activity or expression of enzymes that produce inflammatory mediators. This includes Cyclooxygenase-2 (COX-2), which produces pro-inflammatory prostaglandins, and Inducible Nitric Oxide Synthase (iNOS), which produces nitric oxide (NO), a molecule that can contribute to inflammation and oxidative stress at high concentrations.
4. Impact on Immune Cells: Research suggests Eriodictyol can influence the function of various immune cells involved in inflammation, such as macrophages and mast cells, reducing their activation and subsequent release of inflammatory substances. Through these diverse actions, Eriodictyol helps to resolve inflammation, reduce tissue damage caused by chronic immune activation, and potentially mitigate the symptoms of inflammatory conditions like inflammatory bowel disease (IBD), arthritis, and asthma. Its dual antioxidant and anti-inflammatory capabilities make it a powerful candidate for addressing diseases where these two processes are intertwined.

Cardiovascular Health Support Protecting the Heart and Vessels with Eriodictyol

Given its antioxidant and anti-inflammatory prowess, it’s not surprising that Eriodictyol shows significant promise for supporting cardiovascular health. Heart disease remains a leading cause of mortality, and oxidative stress and inflammation are key drivers of atherosclerosis and other cardiovascular pathologies. Eriodictyol contributes to cardiovascular wellness through several potential mechanisms

1. Anti-Atherosclerotic Effects: Atherosclerosis, the hardening and narrowing of arteries due to plaque buildup, is a major risk factor for heart attacks and strokes. Eriodictyol can potentially slow down or prevent atherosclerosis

• Reducing the oxidation of low-density lipoprotein (LDL) cholesterol, a critical early step in plaque formation. Oxidized LDL is highly pro-inflammatory and taken up by macrophages to form foam cells, the precursors of atherosclerotic plaques.
• Inhibiting the adhesion of monocytes (a type of white blood cell) to the endothelial lining of blood vessels, another crucial early event in atherosclerosis.
• Reducing inflammation within the arterial wall by modulating inflammatory cytokines and pathways as discussed previously.
• Improving endothelial function, the health and flexibility of the inner lining of blood vessels, which is impaired in cardiovascular disease.

2. Lipid Profile Modulation: Some studies suggest Eriodictyol may have a positive impact on lipid profiles, potentially helping to lower levels of total cholesterol, LDL cholesterol (“bad” cholesterol), and triglycerides, while possibly increasing high-density lipoprotein (HDL) cholesterol (“good” cholesterol). These effects contribute to reducing cardiovascular risk.
3. Blood Pressure Regulation: While research is ongoing, Eriodictyol’s ability to improve endothelial function and reduce inflammation could indirectly contribute to healthier blood pressure levels. Endothelial cells produce nitric oxide (NO), a molecule that helps relax blood vessels and lower blood pressure. By protecting endothelial cells from oxidative stress and inflammation, Eriodictyol might support NO production and vasodilation.
4. Potential Antiplatelet Effects: Platelet aggregation is crucial for blood clotting, but excessive aggregation can lead to dangerous thrombi (blood clots) that cause heart attacks and strokes. Some flavonoids have antiplatelet properties, and preliminary research might explore if Eriodictyol shares this potential, further contributing to its cardiovascular protective profile. By addressing multiple facets of cardiovascular risk – oxidative stress, inflammation, lipid profiles, and endothelial function – Eriodictyol presents itself as a promising natural compound for supporting heart and vascular health.

Neuroprotective Potential Eriodictyol for Brain Health and Cognitive Function

The brain is particularly vulnerable to oxidative stress and inflammation, which are implicated in aging-related cognitive decline and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Eriodictyol’s powerful antioxidant and anti-inflammatory properties translate into significant potential for protecting brain health.

1. Crossing the Blood-Brain Barrier: For a compound to exert direct effects on the brain, it must be able to cross the blood-brain barrier (BBB), a highly selective filter. While the permeability of Eriodictyol aglycone itself across the BBB is still under investigation and likely limited, its circulating metabolites (such as glucuronides and sulfates) may have better BBB permeability or exert indirect effects by influencing endothelial cells of the brain microvasculature. Research is ongoing to clarify which forms reach the brain and in what concentrations.
2. Combating Oxidative Stress in the Brain: Once in the brain, Eriodictyol or its metabolites can protect neurons and other brain cells from oxidative damage caused by ROS/RNS. This is crucial because neurons are energy-intensive and produce significant amounts of oxidants, and their membranes are rich in polyunsaturated fatty acids, making them susceptible to lipid peroxidation. By scavenging radicals and boosting endogenous antioxidant defenses, Eriodictyol helps maintain neuronal integrity.
3. Reducing Neuroinflammation: Neuroinflammation, driven by activated microglia and astrocytes, plays a critical role in the progression of neurodegenerative diseases. Eriodictyol’s ability to inhibit pro-inflammatory mediators and pathways like NF-κB can help quell this neuroinflammation, reducing damage to neurons and supporting a healthier brain environment.
4. Protecting Against Neurotoxicity: Studies suggest Eriodictyol can protect neurons from various insults, including excitotoxicity (damage caused by excessive stimulation by neurotransmitters like glutamate), amyloid-beta toxicity (a key feature of Alzheimer’s disease), and damage induced by neurotoxins.
5. Supporting Synaptic Function and Plasticity: Emerging research hints that Eriodictyol might support synaptic health, the connections between neurons crucial for learning and memory. By reducing oxidative stress and inflammation, it helps maintain the structural and functional integrity of synapses. There’s also preliminary interest in its potential to influence pathways related to neurogenesis (the birth of new neurons) and synaptic plasticity, processes vital for cognitive function and adaptation.
6. Potential Cognitive Benefits: While human clinical trials are needed, the protective effects on neurons, reduction of oxidative stress/inflammation, and potential support for synaptic function suggest that Eriodictyol could have benefits for cognitive function, including improvements in memory, learning, and protection against age-related cognitive decline. The neuroprotective potential of Eriodictyol is a highly active area of research, offering hope for natural strategies to support brain aging and potentially mitigate the burden of neurodegenerative diseases.

Metabolic Health Support Eriodictyol and Blood Sugar Regulation

Metabolic syndrome and type 2 diabetes are growing global health concerns, characterized by insulin resistance, high blood sugar, dyslipidemia, and obesity. Eriodictyol shows promise in supporting metabolic health and potentially helping to manage blood sugar levels.

1. Improving Insulin Sensitivity: Insulin resistance, where cells don’t respond effectively to insulin, is a hallmark of type 2 diabetes. Some studies suggest Eriodictyol may help improve insulin sensitivity, allowing glucose to be taken up more efficiently by muscle and fat cells, thereby lowering blood sugar levels. This could involve influencing insulin signaling pathways.
2. Reducing Glucose Absorption: Certain flavonoids can interfere with the absorption of glucose from the digestive tract. While specific mechanisms for Eriodictyol are still being elucidated, this could be one way it impacts post-meal blood sugar spikes.
3. Protecting Pancreatic Beta Cells: Pancreatic beta cells produce insulin. In diabetes, these cells can become dysfunctional or die due to oxidative stress, inflammation, and glucotoxicity (damage from high glucose). Eriodictyol’s antioxidant and anti-inflammatory properties can help protect beta cells from these insults, preserving their function and insulin production capacity.
4. Modulating Glucose Metabolism Enzymes: Eriodictyol may influence the activity of enzymes involved in glucose production (gluconeogenesis) or breakdown (glycolysis) in the liver, potentially helping to regulate hepatic glucose output.
5. Addressing Associated Metabolic Issues: By reducing oxidative stress and inflammation, Eriodictyol can also indirectly benefit other components of metabolic syndrome, such as dyslipidemia and fatty liver disease, which are often co-occurring conditions. While more clinical research is needed, the preclinical evidence suggests Eriodictyol holds potential as a complementary approach for supporting healthy glucose metabolism and potentially mitigating the risks associated with metabolic syndrome and type 2 diabetes.

Liver Protection (Hepatoprotective Effects) of Eriodictyol

The liver is a central metabolic organ frequently exposed to toxins, pathogens, and metabolic overload, making it susceptible to damage from oxidative stress and inflammation. Eriodictyol exhibits significant hepatoprotective properties.

1. Protecting Liver Cells from Oxidative Damage: The liver performs numerous metabolic processes that generate ROS. Eriodictyol’s potent antioxidant activity directly scavenges these radicals and boosts the liver’s own antioxidant defense enzymes (like SOD, CAT, GPx), protecting hepatocytes (liver cells) from oxidative injury.
2. Anti-Inflammatory Actions in the Liver: Chronic inflammation is a key factor in the progression of various liver diseases, including non-alcoholic fatty liver disease (NAFLD) and viral hepatitis. Eriodictyol’s ability to suppress pro-inflammatory cytokines and inhibit inflammatory pathways (like NF-κB) helps to reduce hepatic inflammation and prevent fibrotic changes.
3. Protection Against Toxin-Induced Liver Injury: Studies have shown Eriodictyol can protect the liver from damage induced by various toxins, such as carbon tetrachloride (CCl4) or acetaminophen (paracetamol) overdose, which are commonly used in experimental models to induce liver injury. It achieves this by reducing oxidative stress, inflammation, and preventing hepatocyte apoptosis (programmed cell death).
4. Potential Benefits in Fatty Liver Disease: NAFLD is characterized by excessive fat accumulation in the liver, often associated with obesity and metabolic syndrome. Oxidative stress and inflammation play significant roles in NAFLD progression. By reducing these factors and potentially influencing lipid metabolism, Eriodictyol may offer therapeutic benefits for managing fatty liver. The hepatoprotective effects of Eriodictyol underscore its potential as a supportive agent for maintaining liver health in the face of various challenges.

Exploring Anti-Cancer Properties Eriodictyol’s Role in Cancer Prevention and Treatment Research

Research into the potential anti-cancer effects of natural compounds is a major area of interest, and Eriodictyol has shown promise in preclinical studies. It’s crucial to note that this research is primarily in vitro (cell culture) and in vivo (animal models), and Eriodictyol is not a substitute for conventional cancer treatment. However, its mechanisms suggest potential as a chemopreventive agent or as an adjunct therapy.

1. Inhibition of Cancer Cell Proliferation: Eriodictyol has been shown to inhibit the uncontrolled growth and division of various cancer cell lines, including those from colon, breast, prostate, liver, and leukemia.
2. Induction of Apoptosis: Many anti-cancer agents work by inducing apoptosis (programmed cell death) in cancer cells, a process that is often impaired in malignancy. Eriodictyol has been observed to trigger apoptotic pathways in cancer cells, leading to their demise.
3. Cell Cycle Arrest: Cancer cells have disrupted cell cycle control, leading to rapid proliferation. Eriodictyol can potentially induce cell cycle arrest in cancer cells, preventing them from dividing.
4. Inhibition of Angiogenesis: Tumors require a blood supply to grow beyond a certain size and metastasize. Angiogenesis is the formation of new blood vessels. Eriodictyol may inhibit angiogenesis, thereby starving tumors and limiting their growth and spread.
5. Inhibition of Metastasis: Metastasis, the spread of cancer cells to distant sites, is the primary cause of cancer-related deaths. Preliminary research suggests Eriodictyol might interfere with processes involved in metastasis, such as cell migration and invasion.
6. Antioxidant and Anti-Inflammatory Contribution: While direct mechanisms against cancer cells are studied, Eriodictyol’s general antioxidant and anti-inflammatory properties are also relevant to cancer prevention, as chronic oxidative stress and inflammation can contribute to tumor initiation and promotion. While highly promising, the anti-cancer potential of Eriodictyol requires extensive further research, particularly in human clinical trials, to determine its efficacy and safety in preventing or treating cancer.

Skin Health Benefits Eriodictyol’s Role in Protecting and Rejuvenating Skin

The skin, our largest organ, is constantly exposed to environmental stressors, particularly UV radiation and pollutants, which induce oxidative stress and inflammation, leading to premature aging and damage. Eriodictyol’s protective properties extend to skin health.

1. Protection Against UV-Induced Damage: UV radiation from the sun is a major cause of skin aging (photoaging) and skin cancer. Eriodictyol’s potent antioxidant activity helps neutralize the free radicals generated by UV exposure, reducing damage to skin cells, collagen, and elastin fibers.
2. Reducing Skin Inflammation: Eriodictyol’s anti-inflammatory effects can help soothe irritated skin and potentially alleviate symptoms of inflammatory skin conditions like dermatitis, eczema, and psoriasis by reducing redness, swelling, and itching.
3. Potential Anti-Aging Effects: By combating oxidative stress and inflammation, two key drivers of skin aging, Eriodictyol may help preserve skin elasticity, reduce wrinkle formation, and maintain a more youthful appearance. It might also support collagen synthesis, although more research is needed in this specific area.
4. Wound Healing: Some flavonoids have shown benefits in wound healing by reducing inflammation and promoting tissue regeneration. While specific research on Eriodictyol in wound healing is less extensive, its general protective properties suggest potential in this area. Eriodictyol can be considered both for topical applications (as an ingredient in skincare products) and potentially for systemic benefits through diet or supplementation to support skin health from within.

Immune System Modulation How Eriodictyol Influences Immune Responses

The immune system is a complex network responsible for defending the body against pathogens and abnormal cells, while also regulating inflammation. Eriodictyol appears to modulate immune responses, helping to maintain balance.

1. Reducing Excessive Inflammation: As discussed earlier, Eriodictyol inhibits the production of pro-inflammatory cytokines and modulates inflammatory pathways, which is crucial for preventing chronic inflammation and autoimmune reactions where the immune system mistakenly attacks the body’s own tissues.
2. Influencing Immune Cell Function: Studies suggest Eriodictyol can impact the function of various immune cells, such as macrophages, lymphocytes, and mast cells, influencing their activation status, cytokine production, and ability to respond appropriately to stimuli.
3. Potential Antiviral Effects: Some research has explored the potential of Eriodictyol and other flavonoids from Yerba Santa to exhibit antiviral activity, although this area requires more investigation to determine clinical relevance.
4. Balancing Immune Responses: Rather than simply boosting or suppressing immunity, Eriodictyol seems to promote a more balanced immune response, dampening hyper-responsiveness (inflammation, allergy) while potentially supporting appropriate defenses against pathogens. This modulatory effect on the immune system adds another layer to Eriodictyol’s therapeutic potential, particularly in conditions involving dysregulated immunity.

Other Potential Benefits A Glimpse into Emerging Research on Eriodictyol

Beyond the major areas discussed, research is exploring other potential health benefits of Eriodictyol

• Eye Health: Oxidative stress contributes to age-related macular degeneration and cataracts. Eriodictyol’s antioxidant properties could potentially offer protection for eye tissues.
• Respiratory Health: Its anti-inflammatory and antioxidant effects might be beneficial in inflammatory respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD), helping to reduce airway inflammation and oxidative damage.
• Gut Health: Flavonoids can interact with the gut microbiota, influencing its composition and activity. This interaction might contribute to some of Eriodictyol’s systemic effects or directly benefit gut barrier function and reduce gut inflammation. These areas are still in early stages of research, but they highlight the broad potential of this versatile flavonoid.

Synergistic Effects Combining Eriodictyol with Other Compounds

An important aspect of natural product research is understanding synergy – how compounds interact to produce combined effects greater than the sum of their individual effects. Eriodictyol is found in nature alongside other beneficial compounds, such as Hesperidin and Naringenin in citrus, or other unique phytochemicals in Yerba Santa.

1. Synergy with Other Flavonoids: Eriodictyol may exhibit synergistic or additive effects when combined with other antioxidants and anti-inflammatory flavonoids. For example, combining it with Hesperidin or Naringenin, which share structural similarities but have distinct biological activities, might offer enhanced protection against oxidative stress, inflammation, or cardiovascular disease compared to using a single compound alone.
2. Enhancing Bioavailability: Some compounds can improve the bioavailability of others. While speculative, exploring combinations that might enhance Eriodictyol’s absorption or metabolic profile could be a future research direction.
3. Complementary Mechanisms: Combining Eriodictyol with compounds that act via different but complementary mechanisms could offer more comprehensive therapeutic benefits, such as combining its anti-inflammatory action with an agent that directly targets a different disease pathway. Understanding these potential synergies is crucial for developing effective dietary strategies or multi-compound supplements that maximize the health benefits of Eriodictyol.

Bioavailability, Dosage, and Safety Considerations for Eriodictyol Supplementation

As with any dietary supplement, understanding bioavailability, appropriate dosage, and safety is paramount.

• Bioavailability: As mentioned earlier, Eriodictyol’s bioavailability is a key factor influencing its efficacy. It is absorbed in the gut and undergoes significant metabolism. Factors like the form consumed (aglycone vs. glycoside), the presence of other food components, and individual differences in gut microbiota and liver enzymes can affect how much Eriodictyol and its active metabolites reach systemic circulation. Further research is needed to optimize delivery methods and understand inter-individual variability.
• Dosage: There are currently no established Recommended Daily Allowances (RDAs) for Eriodictyol. Dosage information from research studies varies widely depending on the model (cell culture, animal) and the specific health outcome being investigated. Human studies using isolated Eriodictyol are limited, making it difficult to recommend specific dosages for supplementation. Dosages used in animal studies, when translated to humans, often suggest ranges that would require concentrated extracts. It’s important to note that the amount of Eriodictyol obtained from typical dietary sources like citrus fruits varies and is generally much lower than doses used in experimental settings showing significant effects.
• Safety: Eriodictyol is a natural component of foods widely consumed by humans (citrus). Based on its presence in the diet and limited toxicity data from preclinical studies, it is generally considered safe for consumption in amounts typically found in food. However, the safety of high-dose, concentrated supplementation has not been extensively studied in humans. Potential interactions with medications have not been thoroughly investigated. As with any supplement, individuals with underlying health conditions, pregnant or breastfeeding women, and those taking medications should consult a healthcare professional before starting Eriodictyol supplementation. Current knowledge suggests Eriodictyol derived from dietary sources or moderate supplementation is likely safe, but more research, especially long-term human studies at various dosages, is needed to fully establish its safety profile and optimal intake levels.

2. Bioavailability and Metabolism in Humans: More detailed studies are needed to understand the absorption, distribution, metabolism, and excretion of Eriodictyol and its metabolites in humans, and how these processes vary among individuals. Research into strategies to improve bioavailability is also important.
3. Mechanisms of Action: While many mechanisms have been identified, deeper exploration of specific molecular targets and signaling pathways influenced by Eriodictyol and its metabolites is warranted.
4. Synergistic Effects: Investigating how Eriodictyol interacts with other dietary compounds, medications, or gut microbiota could reveal new therapeutic strategies.
5. Targeted Delivery Systems: Developing methods for targeted delivery of Eriodictyol to specific tissues or organs could enhance its efficacy and reduce potential off-target effects.
6. Standardization of Extracts: For supplement development, standardizing extracts based on active Eriodictyol content (including key metabolites) is important to ensure consistency and reliability. Addressing these research gaps will provide clearer guidance on the therapeutic utility, optimal use, and safety of Eriodictyol as a dietary supplement.
