It is worth noting that after AGE consumption, when immune cells were stimulated ex vivo we found both enhanced NK proliferation and increased expression of the surface receptor NKG2D on those cells (19). Tissue damage caused by an overactive immune system creates a cycle whereby the immune system attempts to repair the damage, which, in turn, creates more inflammation and potentially more damage (Figure 1). Potential mechanisms by which diet may influence immunity, inflammation, and/or oxidative stress. Fructo-oligosaccharide and Nα-fructosyl arginine are aged garlic compounds that have structures resembling pathogen-associated molecular patterns, with the potential to interact with immune cells (3). The results also suggest that the immune system functions well with AGE supplementation, perhaps with less accompanying inflammation. var rcel = document.createElement("script"); Immunity requires GSH for 2 reasons. Known as Allium sativum in scientific circles, garlic is considered one of the best disease-preventing foods because of its potent and widespread effects. Garlic has blood pressure-lowering properties and the mechanism of action is biologically plausible. These results suggest that, although not helping to prevent an illness, the addition of AGE to the diet could be useful in reducing illness severity. Previous studies also suggest that aged garlic extract is more effective than a placebo for lowering systolic blood pressure in those with uncontrolled hypertension. Participants' average age was 26 y and 60% were female.

So can a certain amount of aged garlic extract actually be bad for the body? Aged garlic extract has become a nutritional powerhouse. First, because the immune system produces free radicals to kill pathogens, GSH serves to protect the host immune cells with its antioxidant activity. They concluded that AGE alters the cytokine pattern toward T helper (Th) 1, whereas aflatoxin B1 alters the cytokines into a Th2 pattern. Aggarwal NR, Tsushima K, Eto Y, Tripathi A, Mandke P, Mock JR, Garibaldi BT, Singer BD, Sidhaye VK, Horton MR, et al. The organosulfur components of AGE’S-allyl cysteine and S-propyl cysteine, are water soluble and help fortify the liver’s glutathione production. In addition, Lautenbach et al. In a population of cells from participants who consumed AGE for 45 d, the γδ-T and NK cells were able to proliferate better in ex vivo cultures than cells from those who consumed the placebo (19).The γδ-T cells nearly doubled their ability to proliferate, whereas the NK cells almost tripled their proliferation numbers when compared with preconsumption values. It has been suggested that AGE may help regulate body weight by increasing sugar metabolization; and it supports brain health by benefitting memory and nerve growth. Check price at AmazonWhile other garlic supplements focus on delivering an equivalent dose of raw garlic material, Zhou Nutrition sets its priorities higher: it aims to deliver at least 5000 micrograms of allicin, the compound in garlic that many nutritionists believe is responsible for its health benefits. Incidence of self-reported cold or flu (A), number of symptoms reported by participants who became ill (B), and number of days that participants reported a decrease in their normal routines due to illness during consumption of an AGE supplement (2.56 g/d; n = 56) or a placebo (n = 56) for 90 d. P values are shown when the groups differed significantly (z-test of proportions). Chronic inflammation results from the prolonged activation of immunity or an inability to resolve the immune response and is associated with many disease states such as metabolic syndrome, high blood pressure, atherosclerosis, diabetes, and arthritis (14, 15). The purpose of this review was to summarize the influence of aged garlic extract (AGE) on the immune system. rcel.async = true; Additionally, as garlic ages it loses its strong flavor, so there's no need to … In recent studies, it has shown potential for reducing risk factors that can lead to heart disease, such as … It is unclear why the individuals in the placebo group had lower GSH concentrations after the study than they did before the study began. The author's laboratory is interested in AGE's effects on cell proliferation and activation and inflammation and to learn whether those changes might affect the occurrence and severity of colds and flu. Over 12 formulas developed specifically to support cardiovascular, immune and cognitive health and overall well-being. Listing a study does not mean it … ; Organic Health Ltd.; Oy Valioravinto Ab; Purity Life Health Products L.P.; PT Nutriprima Jayasakti; Vitaco Health Ltd.; Vitae Natural Nutrition; Sanofi Consumer Health Care; Wakunaga Pharmaceutical Co., Ltd.; and Wakunaga of America Co., Ltd. Clinical and Inflammatory Features of Exacerbation-Prone Asthma: A Cross-Sectional Study Using Multidimensional Assessment. This led us to hypothesize that AGE supplementation might reduce inflammation in a chronically inflamed population. Garlic contains numerous compounds that have the potential to influence immunity. Researchers discovered that SAC inhibits cholesterol formation by decreasing the production of HMG-CoA reductase. AGE alone also increased survival time, reduced tumor growth, and increased the production of IFN-γ (17). AGE also lowers levels of homocysteine, an amino acid related to a high risk for heart disease. It is thought that garlic is native to Siberia, but spread to other parts of the world over 5000 years ago. The effect on cold and flu symptoms was determined by using daily diary records of self-reported illnesses. The aging process also helps remove many of the irritants, oxidants, and odorous components from raw garlic. Because garlic thins the blood, consult a physician before taking the supplement if you are currently taking any medication. Aged Garlic Extract (AGE) has been the subject of more than 700 medical studies assessing its various aspects, including garlic’s benefits for cardiovascular health, immunity support, and even cognition. T-regulatory cells are involved in the transition from inflammation to resolution of inflammation (12), and there is an active coordinated process of apoptosis and clearance of cells by macrophages (13). It also supports healthy cell production at the DNA level. The odorless extract obtained is … This process naturally stabilizes the sulfur compounds found in garlic, making it easier to digest and increasing its antioxidant content. AGE is slightly different than the garlic clove used for cooking. Presented at the conference "2014 International Garlic Symposium: Role of Garlic in Cardiovascular Disease Prevention, Metabolic Syndrome, and Immunology," held 4–6 March 2014 at St. Regis Monarch Beach Resort in Dana Point, CA. Building a stronger heart has become vital. These health improvements may prevent cardiac events like a stroke or heart attack.

Ebrahimpour et al. It also lowers bad cholesterol (LDL), increases good cholesterol (HDL), and decreases calcified plaque buildup. Once the threat has been removed, the immune system returns to surveillance mode (arrow 3). Adipose tissue actively secretes adipokines, cytokines, and chemokines, and the more adipose tissue one has, the more inflammatory mediators will be secreted (29). Inflammation is the product of an immune cell response, which is necessary and valuable for pathogen elimination and wound healing. Do the antioxidant properties of AGE help protect against the free radicals that damage the host and that set up a vicious cycle of tissue damage, inflammation, and more tissue damage? Although not many γδ-T cells are found in the blood, they are numerous in the intestine and epithelial linings of the lung and genitourinary tract. Similar to other garlic forms (powder, oil, or extract), AGE must be processed before it can be used as a supplement. It is well known that obesity is associated with chronic inflammation in both adults (27) and children (28). Two innate lymphocytes, γδ-T and natural killer (NK) cells, appear to be susceptible to diet modification. With 55% of the placebo group and 45% of the AGE group reporting illnesses, no significant difference in the incidence of colds and flu was seen between the groups (Figure 2A). Once the immune system has eliminated the pathogen, it then returns to surveillance mode by an active process of resolving inflammation. Healthy human participants (n = 120), between 21 and 50 y of age, were recruited for a randomized, double-blind, placebo-controlled parallel-intervention study to consume 2.56 g AGE/d or placebo supplements for 90 d during the cold and flu season. AGE is slightly different than the garlic clove used for cooking. Changes in serum SAC and PBMC cytosol GSH concentrations in adults who received 2.56 g AGE/d or placebo for 45 d1. Baseline values were subtracted from the values at 45 d. The negative value in the placebo group indicates that GSH concentrations were lower at the end of the study. Aged garlic is used to make AGE (aged garlic extract), a popular herbal supplement that has been proven to boost the immune system and possibly prevent cancer and cardiovascular disease. Taking these results into consideration, we concluded that supplementing the diet with AGE resulted in enhanced immune cell function, and perhaps under less inflammatory conditions. AGE plus naltrexone increased survival times, tumor growth inhibition, and the immune response, mainly cytotoxicity, as well as the CD4+-to-CD8+ ratio and IFN-γ production (16). Chandrashekar PM, Prashanth KVH, Venkatesh YP. Surveillance by the immune system allows for the destruction of potential pathogens, without any accompanying signs of illness. The paper noted that aged garlic extract has been known to have a variety of pharmacological effects, including anti-allergenic, anti-tumor and anti-psychological stress effects. His dedication to good science and his voice for nutrition are remembered and sorely missed. The symposium was supported by Agencias Motta S.A.; Bionam; Eco-Nutraceuticos; Healthy U 2000 Ltd.; Magna; Mannavita Bvba; MaxiPharma; Medica Nord A.S.; Nature's Farm Pte. Naltrexone, an opioid antagonist, was used with or without AGE. These results suggest that AGE supplementation may enhance immune cell function and may be partly responsible for the reduced severity of colds and flu reported. No studies, to our knowledge, have examined the effect of AGE on γδ-T cells, and this cell has been shown by our previous studies to be modified by diet (21, 22). Chandrashekar and Venkatesh (4) showed that the fructans from AGE were a well-tolerated adjuvant to IgG production when mice were treated with ovalbumin as the antigen. The Th1 pattern is beneficial to immunity in general and to antitumor immunity specifically. Immune cells, especially innate immune cells, are responsible for the inflammation necessary to kill pathogens. Second, lymphocytes are dependent on adequate GSH concentrations; T cell proliferation and NK cell cytotoxic activity are functions that are impaired under low GSH conditions (25, 26). The expression of CD314 [natural killer group 2 member D (NKG2D)], a marker of activity, on the surface of NK cells was significantly greater after AGE supplementation, suggesting the potential for more cytolytic activity by NK cells. Aged garlic extract (AGE) 4 is manufactured from organically grown garlic cloves (Allium sativum L.) that are sliced and soaked in an aqueous ethanol solution and extracted and aged up to 20 mo. Immune function is reduced in obese and overweight people, and yet they are in a chronic state of inflammation. Published in a supplement to The Journal of Nutrition. Aged Garlic Extract Study (AGE) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. (31) found a reduction in NK cells in the livers of obese individuals. Tetrahydro-β-carboline (5), Nα-(1-deoxy-D-fructos-1-yl)-L-arginine (6), and S-allyl-L-cysteine (SAC) (7, 8) are compounds in AGE that were shown to have antioxidant and protective effects against neurodegeneration, cardiotoxicity, and diabetic complications. What is important, however, is that many, if not all, of our disease risks are associated with chronic inflammation. Surveillance is the state in which the immune system removes the pathogen without causing symptoms related to illness. This response includes the proliferation of immune cells and the subsequent activation of those cells, characterized by increased expression of cell surface receptors and the synthesis and secretion of cytokines. AGE also assists in the conversion of enzymes in the liver, which are responsible for the detoxification of heavy metals, chemicals, and other toxins. Aged Garlic Extract is a Great Place to Start. Supplement Coordinator disclosures: SS Percival has been awarded research grants from Wakunaga of America Co., Ltd., and received an honorarium for serving as Vice-Chair of the conference. It’s a good source of manganese, vitamin B6, vitamin C, selenium, and fiber. })(); I went over this web site and I believe you have a lot of wonderful Participants (n = 120) were instructed to keep a daily diary of symptoms related to illness as a secondary study outcome. Notify me of follow-up comments by email. The literature is replete with research that endorses the concept of inappropriate immunity leading to inflammation, whether as chronic inflammatory activity or an inability to resolve an immune response. Your Microbiome is as Unique as You Are. Capsules were consumed for a total of 90 d, and the blood draw was taken at the beginning and at 45 d to determine if immune changes had occurred. It’s time to bring garlic from the kitchen to the medicine cabinet. Theories to define what might be responsible for creating this problem have included the following: alterations in adipokine synthesis and secretion, oxidative stress, adipose tissue hypoxia, endoplasmic reticulum stress, and FA-induced inflammation (29). Susan S Percival, Aged Garlic Extract Modifies Human Immunity, The Journal of Nutrition, Volume 146, Issue 2, February 2016, Pages 433S–436S, https://doi.org/10.3945/jn.115.210427. This publication must therefore be hereby marked "advertisement" in accordance with 18 USC section 1734 solely to indicate this fact. It boosts the activity of natural killer cells, which attack foreign bacteria and virus cells, a first line of defense against the common cold and other infections. The incubation medium or extract is then filtered and concentrated to dryness and is stored at −20°C for further studies. After 45 d of AGE consumption, γδ-T and NK cells proliferated better and were more activated than cells from the placebo group. var referer="";try{if(referer=document.referrer,"undefined"==typeof referer)throw"undefined"}catch(exception){referer=document.location.href,(""==referer||"undefined"==typeof referer)&&(referer=document.URL)}referer=referer.substr(0,700); Aged Garlic Extract (AGE) – Part I: The Different Forms of Garlic and Why AGE Is A Better Health Choice Michael Garko, Ph.D. AGE is easier on the stomach and highly digestible, but it may cause heartburn, in some cases, if taken on an empty stomach. When Garlic is aged, it becomes a “tonic herb.” When a herb is tonic this means it can be taken safely for long periods of time without causing disruptions to your system. Mapping the Human Milk Microbiome: Impetus for a Long-Awaited Renaissance in Maternal and Infant Nutrition Research? AGE, aged garlic extract; GSH, reduced glutathione; PBMC, peripheral blood mononuclear cell; SAC, S-allyl-L-cysteine. In healthy persons, the immune system lives in surveillance mode, with cells migrating through the blood and lymph systems to detect pathogens in the body (Figure 1). Outcome of Patients Admitted to Intensive Care Units due to Influenza-Related Severe Acute Respiratory Illness in 2017-2018 Flu Season: A Multicenter Study from Turkey. If a dietary supplement derived from garlic could help to alleviate the consequences of this type of inflammation, this could only lead to improved health outcomes in the general population. Cardio Among many benefits, AGE may prevent cardiovascular disease. The authors noted that aged garlic extract also has the potential to improve inflammation, arterial stiffness, and other cardiovascular markers in patients with high blood pressure. Tramonti D, Andrew EM, Rhodes K, Newton DJ, Carding SR. Ballatori N, Krance SM, Notenboom S, Shi S, Tieu K, Hammond CL. AGE also helps the body slow the release of histamine, an immune-system response that is commonly associated with allergies. SSP had responsibility for all parts of the manuscript. Visser M, Bouter LM, McQuillan GM, Wener MH, Harris TB. 06 ($5.77/Fl Oz) $31.95 $31.95 Detox Another important benefit of AGE is its ability to help the liver. Aged Garlic Extract. Publication costs for this supplement were defrayed in part by the payment of page charges. The study continued for another 45 d to capture the full cold and flu season. (arrow 2). In the peripheral blood of overweight and obese individuals, increased inflammation has been represented by a higher neutrophil-to-lymphocyte ratio, elevated high-sensitivity C-reactive protein, and increased chemokines (30). More than garlic. Aged garlic extract (AGE) differs from dietary garlic and most garlic supplements because, as indicated by its name, it is naturally aged for 20 months. (7) It is highly bioavailable and exerts biological activity in both animals and humans. Aged garlic extract (AGE) is a supplement which is high in antioxidants and is said to regulate blood pressure, lower cholesterol, and cleanse the blood.This supplement is created by carefully aging raw garlic before processing it into gel capsules or powder. Ltd.; Nature Valley W.L.L. This makes this garlic supplement especially attractive if you are trying to design your supplementation routine to mirror the scientific research … For our randomized, double-blind, placebo-controlled, parallel-intervention study, we recruited 120 healthy individuals, 60 for each group, to determine the effect of consuming 2.56 g AGE daily. Copyright © 2020 American Society for Nutrition. Aged garlic extract (AGE)4 is manufactured from organically grown garlic cloves (Allium sativum L.) that are sliced and soaked in an aqueous ethanol solution and extracted and aged up to 20 mo. Recent studies have shown that AGE contains powerful antioxidant compounds, such as carboxylic acid and L-arginine, which play important roles in combating oxidant-induced conditions that occur as the body ages. Can diet, or more specifically AGE, improve immune surveillance, improve the immune response, and/or help inflammation subside? AGE provides critical nutrients used by the body to produce its own antioxidants for protecting itself from radiation, neutralizing chemicals, and clearing out toxins. Numerous compounds have been detected in AGE that have the potential to affect immunity, including the lectin family, which is known to interact with pathogen recognition receptors on immune … Same thing statins do returns to surveillance mode by an active process resolving.
