Composition of Yerba Mate
Yerba Mate is rich in bioactive compounds, including polyphenols, xanthines, saponins, and various vitamins and minerals. The primary polyphenols found in Yerba Mate are chlorogenic acids, which are known for their antioxidant properties. Other significant compounds include quercetin, kaempferol, and rutin, which contribute to its health-promoting effects4.
Health Benefits of Yerba Mate
Antioxidant Properties
Yerba Mate has been shown to possess strong antioxidant properties. Studies have demonstrated that both organic and conventional Yerba Mate can prevent oxidative damage in the liver and serum, enhancing enzymatic and non-enzymatic defenses5. Additionally, microencapsulation of Yerba Mate extracts has been found to increase its bioactivity, leading to higher antioxidant activities in vivo1.
Cardiovascular Health
Regular consumption of Yerba Mate has been linked to improved cardiovascular health. It has been shown to reduce blood lipid concentrations, including total cholesterol, LDL, and triglycerides, while also lowering blood pressure in both normocholesterolemic and hypercholesterolemic individuals4. Furthermore, Yerba Mate has been found to improve blood viscosity and microcirculation, which are critical factors in preventing cardiovascular diseases8.
Anti-inflammatory Effects
Yerba Mate exhibits significant anti-inflammatory properties. It has been shown to attenuate both central and peripheral inflammatory effects of diet-induced obesity in rats, reducing pro-inflammatory markers and improving insulin pathway regulation7. This suggests that Yerba Mate could be beneficial in managing obesity-related inflammation.
Metabolic Benefits
Yerba Mate has been found to have positive effects on lipid metabolism. In hyperlipidemic models, Yerba Mate tea significantly decreased body weight gain and serum lipid levels, improved antioxidant enzyme activity, and modulated the expression of genes involved in lipid metabolism3. These findings indicate its potential in managing hyperlipidemia and related metabolic disorders.
Probiotic Growth Enhancement
In vitro studies have shown that Yerba Mate can enhance the growth of probiotic bacteria, such as Lactobacillus acidophilus and Pediococcus, which are beneficial for gut health. However, its effectiveness as a feed additive in reducing Salmonella colonization in broiler chickens was not significant in vivo2.
Potential Applications of Yerba Mate
Given its wide range of health benefits, Yerba Mate has potential applications in various fields:
Nutraceuticals: Yerba Mate can be used in the development of functional foods and beverages aimed at improving antioxidant status and cardiovascular health.
Therapeutic Strategies: Its anti-inflammatory and lipid-lowering properties make it a candidate for therapeutic strategies targeting metabolic and cardiovascular diseases.
Animal Feed: While its effectiveness in reducing foodborne pathogens in animals needs further investigation, Yerba Mate could be explored as a supplement to enhance gut health in livestock.

Adverse Effects of Yerba Mate
Impact on Body Weight and Performance in Animals
Yerba Mate decreased body weight and adipose tissue in high-fat diet-induced obese mice and hamsters, suggesting a potential for weight management1 6 10. However, in broiler chickens, Yerba Mate decreased body weight and negatively impacted the performance of probiotic treatments4.
Inflammatory and Oxidative Stress Effects
Yerba Mate has been shown to reduce both central and peripheral inflammatory effects in diet-induced obese rats, indicating anti-inflammatory properties3. Additionally, it reduced oxidative stress and pulmonary damage in mice exposed to cigarette smoke5.
Metabolic and Cardiovascular Effects
Yerba Mate improved lipid profiles and cardiovascular health in both normocholesterolemic and hypercholesterolemic subjects, reducing total cholesterol, LDL, triglycerides, and blood pressure7. It also increased antioxidant capacity by raising serum levels of paraoxonase-1 (PON-1)2.
Potential Adverse Effects
In broiler chickens, Yerba Mate decreased body weight and reduced the effectiveness of probiotics in preventing Salmonella colonization, suggesting potential negative interactions with other treatments and a decrease in overall performance4.

How has Yerba Mate Improved Patient Outcomes?
Cardiovascular Health Improvement
Yerba Mate consumption has been shown to improve blood viscosity and microcirculation, reducing key risk factors for cardiovascular diseases such as atherosclerosis and thrombosis1.
Regular intake of Yerba Mate significantly decreased blood lipid concentrations (total cholesterol, LDL, triglycerides) and blood pressure, particularly in hypercholesterolemic subjects5.
Increased serum levels of paraoxonase-1 (PON-1) and HDL cholesterol were observed, indicating enhanced antioxidant capacity and protective effects against atherosclerotic diseases3.
Metabolic and Anti-Diabetic Effects
Yerba Mate has been found to improve glucose metabolism, reducing fasting levels of glucose, insulin, glucagon, and GLP-1, suggesting a potential role in preventing type 2 diabetes6.
The beverage also modulates the PI3K-AKT signaling pathway, improving hepatic insulin signaling and reducing insulin resistance in high-fat diet-induced obese mice4.
Weight Management and Anti-Obesity Effects
Yerba Mate supplementation led to significant reductions in body fat mass, percent body fat, and waist-hip ratio in obese individuals, without significant adverse effects8.
Enhanced fatty acid oxidation during exercise and improved measures of satiety and mood state were observed, indicating potential benefits for weight-loss interventions2.
Molecular and Genomic Effects
Yerba Mate consumption resulted in significant changes in global gene expression profiles, particularly in genes involved in inflammation, cell signaling, and cardiometabolic health, suggesting a protective genomic response7.

Yerba Mate Mechanisms of Action
Lipid Metabolism and Lipid-Lowering Effects
Yerba Mate decreases body weight and serum lipid levels by enhancing antioxidant enzyme activity and improving lipoprotein lipase (LPL) and hepatic lipase (HL) activities. It also modulates gene expression related to lipid metabolism, such as upregulating peroxisome proliferator-activated receptor α (PPARα) and low-density lipoprotein receptor (LDLR), and downregulating sterol regulatory element-binding protein 1c (SREBP-1c) and acetyl CoA carboxylase (ACC)1 9.
Long-term Yerba Mate supplementation increases energy expenditure and thermogenic gene expression in white adipose tissue (WAT), decreases fatty acid synthase (FAS) mRNA expression, and inhibits hepatic lipogenic enzymes, leading to reduced body weight, adiposity, and plasma lipid levels2.
Antioxidant and Anti-inflammatory Effects
Yerba Mate enhances antioxidant activities and reduces lipid peroxidation in plasma and brain tissues, suggesting its role in mitigating oxidative stress4.
It also reduces both central and peripheral inflammatory markers in diet-induced obesity, including decreasing hypothalamic tumor necrosis factor (TNF)-α and increasing anti-inflammatory cytokines like interleukin (IL)-107.
Glucose Metabolism and Insulin Sensitivity
Yerba Mate improves glucose metabolism by decreasing fasting glucose, insulin, and glucagon levels, and enhancing glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) levels, which may help in preventing type 2 diabetes3.
It also improves hepatic insulin signaling by modulating the PI3K-AKT pathway, which includes downregulating genes like Pepck and G6pc and reducing FOXO1 nuclear translocation5.
Cardiovascular Health
Regular consumption of Yerba Mate reduces blood lipid concentrations (total cholesterol, LDL, triglycerides) and blood pressure, thereby lowering cardiovascular risk, especially in hypercholesterolemic subjects8.
It improves vascular endothelial function by reducing endothelin and thromboxane B2 levels, increasing nitric oxide levels, and upregulating LDLR and scavenger receptor B1 (SR-B1) gene expression10.
Probiotic and Antimicrobial Activity
Yerba Mate enhances the growth of probiotic bacteria in vitro, although it does not significantly reduce Salmonella Enteritidis colonization in vivo9.
