Please note: Supplements are generally not FDA tested or approved. Some supplements can interfere with medications and/or cause side effects. Do not delay seeking medical attention for medical concerns by taking supplements without medical advice. Please discuss any and all supplements you take with your health care provider and be sure to follow your provider’s recommendations for your prostate and overall health. Supplements should not be given to children, breast feeding or pregnant women without the specific advice or your medical provider.   Have you ever felt like you’re constantly battling colds or other illnesses? Whether it’s the flu season, allergy season, or just the daily grind, your immune system works hard to keep you healthy. Your immune system is your body’s defense system, protecting you from harmful germs, bacteria, and viruses. A strong immune system helps you recover quickly, while a weak one leaves you feeling run-down. Keeping your immune system strong year-round isn’t about quick fixes. It’s about forming healthy habits and giving your body the support it needs. By making smart choices with your diet, lifestyle, and stress management, you can boost your immune health and feel your best. In this blog, we will share practical ways to support your immune system and stay healthy throughout the year.

Eat a Balanced and Nutrient-Rich Diet

If you want a stronger immune system, start with what’s on your plate. Your body needs vitamins, minerals, and nutrients to fight off illness. Focus on adding more fruits, vegetables, whole grains, lean proteins, and healthy fats to your meals. Foods like citrus fruits, berries, spinach, nuts, and chicken give you key nutrients like vitamins C, D, and E, plus zinc. These help keep your body ready to defend you. Eating a balanced diet doesn’t have to be complicated—stick to simple, whole foods, and your body will thank you.

Support Your Gut Health

A large part of your immune function is located in your digestive tract. When your gut is healthy, your body can better fight off harmful invaders. Probiotics, prebiotics, and supplements that support your gut lining can help maintain a healthy immune system. Using supplements like Mega Mucosa can help support a healthy mucosal barrier, which is essential for strong immune defenses. This supplement contains ingredients that promote microbial diversity and help maintain the gut lining. At places like Lakeland Drug Company, you can find products designed to give your immune system the support it needs. They provide trusted options to help you care for your immune health year-round.

Author Interviews, Brigham & Women's - Harvard, COVID -19 Coronavirus / 05.11.2020

MedicalResearch.com Interview with: Duane Wesemann, MD, PhD Div. of Rheumatology, Immunology and Allergy Brigham and Women's Hospital Boston, MA 02115 Wesemann Lab   MedicalResearch.com: What is the background for this study? Response: There is a lot of variability in how long antibodies to pathogens are produced in humans.  Some infections and vaccinations like measles induce high levels of antibodies that can be produced for a lifetime.  Other infections or vaccinations induce only short lived antibody responses. Also, some people make longer lasting antibodies compared to others.   We wanted to ask what the antibody durability dynamics looked like after COVID-19 and if we could tease out any insights—both with regard to COVID-19 as well as in general.  (more…)
Author Interviews, Flu - Influenza, Genetic Research, PNAS / 10.09.2019

MedicalResearch.com Interview with: Jacob S. Yount, PhD Associate Professor Department of Microbial Infection and Immunity The Ohio State University, College of Medicine Co-Director, Viruses and Emerging Pathogens Program OSU Infectious Diseases Institute MedicalResearch.com: What is the background for this study? Response: Genetic defects in a human protein known as IFITM3 are linked to hospitalization and death upon influenza virus infections.  IFITM3 is an immune system protein that can inhibit virus entry into cells and it is produced as an early response to virus infections.  In order to better study the role of IFITM3 during infections, we engineered a mouse model that lacks this protein.   (more…)
Author Interviews, C. difficile, Pediatrics / 07.08.2019

MedicalResearch.com Interview with: Larry K. Kociolek, MD MSCI Attending Physician, Division of Infectious Diseases, Associate Medical Director of Infection Prevention and Control, Ann & Robert H. Lurie Children’s Hospital of Chicago Assistant Professor of Pediatrics Northwestern University Feinberg School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Clostridioides (Clostridium) difficile colonization is very common among infants, yet infants almost never develop symptoms of infection. In adults, it is known that immunity against the toxins that C. difficile produces protect against C. difficile infection (CDI). Our goal was to determine whether or not infants who become colonized with C. difficile develop an immune response against these toxins. We collected stool from healthy infants at multiple time points during the first year of life to determine whether or not they became colonized with C. difficile. Then at 9-12 months old, we collected blood to see if we can identify antibodies in their blood that protect against these toxins. We discovered that colonization with C. difficile during infancy was strongly associated with the development of antibodies. These antibodies were able to protect against the harmful effects of these toxins in a laboratory cell culture model. (more…)

MedicalResearch.com Interview with: bats-mattaeMatae Ahn,MD-PhD candidate Emerging Infectious Diseases (EID) Programme Duke-NUS Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Bats, as the only flying mammals, are ‘special’ in their ability to host many highprofile viruses without suffering from disease. Such viruses including Ebola virus, Nipah virus and SARS or MERS coronaviruses, are highly pathogenic and often lethal to humans or animals, but yet cause no or minimal disease in bats. In addition, they also live very long relative to their small body size, despite elevated metabolic rates. However, what makes them special is still unclear. In this study, we discovered dampened NLRP3-mediated inflammation in bats in response to both ‘sterile’ stressors and infection with three different types of zoonotic RNA viruses. We identified multiple molecular mechanisms of altered bat NLRP3, a critical regulator of virus-induced and age-related inflammation, as the cause. Importantly, the reduced inflammation had no effect on the viral loads, which suggests enhanced immune tolerance to infection in bats. Bats’ natural ability to dampen stress-related and virusinduced inflammation may be a key mechanism underlying their long lifespans and unique viral reservoir status.  (more…)

MedicalResearch.com Interview with: Brinda Emu, MD Assistant Professor of Medicine (Infectious Diseases) Yale School of Medicine MedicalResearch.com: What is the background for this study? Response: This was a Phase 3 study of a new antiretroviral agent, ibalizumab, for the treatment of HIV-1 infection.  Ibalizumab is a monoclonal antibody that targets the CD4 receptor on host cells.  CD4 is the receptor that HIV uses to infect CD4+ T cells.  By binding to the CD4 receptor, ibalizumab prevents viral entry.  This study recruited patients that harbor multi-drug resistant HIV and were failing their current regimen of antiretroviral agents, and thus had limited options for treatment of their HIV-1 infection using approved medications.

Author Interviews, Infections / 09.03.2018

MedicalResearch.com Interview with: Chih-Chi Andrew Hu, Ph.D. Associate professor in Microenvironment & Metastasis Program Wistar Institute  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: To help our body fight infections, B cells need to differentiate into plasma cells so that they can produce abundant antibodies against pathogens. Antibodies are folded and assembled in the endoplasmic reticulum (ER). Only those perfectly manufactured antibodies are allowed to be released from the ER and delivered to the outside of B cells to fight against the pathogens. IRE1 is a sensor protein that sits on the membrane of the ER, and can respond to B cell differentiation by activating the transcription factor called XBP1s. Activation of XBP1s allows B cells to expand the size of the ER and produce necessary chaperone proteins to help B cells manufacture perfect antibodies. By studying B cells that lack XBP1s, we discovered that these B cells produced dramatically increased levels of IRE1, and such IRE1 acquired phosphorylation at its serine 729 (S729).  (more…)

MedicalResearch.com Interview with: Amanda Mitchell PhD Postdoctoral researcher Institute for Behavioral Medicine Research The Ohio State University Wexner Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study followed 80 pregnant women across the course of their pregnancy – throughout 1st, 2nd, and 3rd trimesters. We examined whether women exhibited different levels of immune markers called cytokines based on fetal sex. We looked at this in two ways – levels of cytokines in the blood, and levels produced by a sample of immune cells that were exposed to bacteria in the laboratory. While women did not exhibit differences in blood cytokine levels based on fetal sex, we found that the immune cells of women carrying female fetuses produced more proinflammatory cytokines when exposed to bacteria. This means that women carrying female fetuses exhibited a heightened inflammatory response when their immune system was challenged compared to women carrying male fetuses. (more…)
Author Interviews, OBGYNE, Pediatrics, Vaccine Studies / 09.10.2016

MedicalResearch.com Interview with: Ameae M. Walker Vice Provost for Academic Personnel Distinguished Teaching Professor Biomedical Sciences School of Medicine University of California, Riverside MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has previously been some evidence that immune cells in breast milk could pass through the wall of the immature gut, but if active they, like antibodies in milk, were considered likely a form of passive immunity. We now show that in addition to some maternal cells being active in the newborn (i.e. that they do contribute to passive cellular immunity), there are, more importantly, others that go to the thymus where they participate in selection of the neonate’s T cells. In this fashion, the neonate develops cells that recognize antigens against which the mother has been vaccinated – a process we have dubbed maternal educational immunity. (more…)

MedicalResearch.com Interview with: David Underhill, PhD Professor of Biomedical Sciences Research scientist, F. Widjaja Foundation Inflammatory Bowel and Immunobiology Research Institute Cedars-Sinai Los Angeles, CA MedicalResearch.com: What is the background for this study? Response: “Innate immunity” is the body’s natural resistance to microbial infection and stands in contrast to “adaptive immunity,” which is the body’s learned response to infection (e.g. antibodies and vaccines). In the standard model of innate immunity that has emerged over the last several decades, scientists have come to understand that the human genome encodes many “receptors” that have evolved as sensors for specific common microbial molecules, such as bacterial or viral DNA or components of bacterial or fungal cell walls. The job of these receptors is to survey the environment (skin, blood, etc.) for potentially dangerous microbes and initiate inflammatory responses if they are found. These activities are essential for defense against infection, and people and animals with defects in these sensors or the responses they trigger can be susceptible to infection. My laboratory has been interested for more than a decade in identifying these innate sensors and the microbial targets that they recognize. In this study, we were looking for the sensor that allows white blood cells (e.g. macrophages and dendritic cells) to detect Gram-positive bacterial cell walls and trigger a specific inflammatory response: secretion of the potent inflammatory mediator interleukin-1β (IL-1β).

Aging, Author Interviews / 15.07.2016

MedicalResearch.com Interview with: Dr. Martin Piskacek Laboratory of Cancer Biology and Genetics Department of Pathological Physiology, Faculty of Medicine, Masaryk University Brno, Czech Republic MedicalResearch.com: What is the background for this study? What are the main findings? Response: From genome-wide expression analyses, the B lymphocytes avoid the aging until 60 years of age. We did not found any gene expression differences between young (30-45 years) and early aged healthy donors (50-60 years). Our results demonstrate the potential of hematopoietic stem cells to generate uncompromised B lymphocytes in early elderly. These are very encouraging findings for general health, because the immunity maintenance does not seem to need artificial intervention to keep B lymphocytes uncompromised in the early elderly.

Author Interviews, Infections, Nature / 02.12.2015

MedicalResearch.com Interview with: Professor Søren Riis Paludan DMSc, PhD Department of Biomedicine Aarhus University Denmark Medical Research: What is the background for this study? What are the main findings? Prof. Paluden: We were interested in understanding the first immune reactions that occur when an organism meets an infectious agent (virus or bacteria). The main finding is that we have identified an immune reaction that is activated as the microbe disturbed the mucus layer at mucosal surfaces. This is an immune reaction occuring earlier than what has been thought previously, and may represent a mechanism that enables the organism to fight most microbes that we meet without mounting strong immune responses. This is important, since strong immune reactions - in addition to contributing to elimination of microbes - also have negative effects such as fever, etc. (more…)
Allergies, Author Interviews / 14.05.2015

Dr. Christine McCusker MD Associate Professor, Department Pediatrics Meakins-Christie Laboratories McGill University and the MUHCRI, Montreal Quebec, CanadaMedicalResearch.com Interview with: Dr. Christine McCusker MD Associate Professor, Department Pediatrics Meakins-Christie Laboratories McGill University and the MUHCRI, Montreal Quebec, Canada Medical Research: What is the background for this study? What are the main findings? Dr. McCusker: When the body is exposed to new substances, the immune system must evaluate the “threat” and choose the type of response that will best protect the host. Allergies and allergic asthma develop after the response to “allergens” follows the TH2-type inflammatory pathway instead of the non-inflammatory tolerant pathway.  Evidence suggests that there is some plasticity in this “choice” and thus it may be possible to influence the immune response to preferentially choose the tolerant pathway when exposed to allergens. We therefore treated very young mice to a molecule designed to inhibit activation of the TH2 pathway. We showed that this early treatment resulted in long-lasting protection from the development of allergies.  Instead of allergic responses, vaccinated animals developed tolerant responses to allergens and did not show any signs of allergies or asthma.  Importantly, while the influence of the treatment was long-lasting, the molecule itself is rapidly removed from the system.

Author Interviews, Genetic Research, Infections, Inflammation, NYU / 07.05.2015

Dr. Ludovic Desvignes. PhD. Assistant Professor, Departments of Medicine and Pathology NYU Langone Medical CenterMedicalResearch.com Interview Dr. Ludovic Desvignes PhD. Assistant Professor, Departments of Medicine and Pathology NYU Langone Medical Center MedicalResearch: What is the background for this study? Dr. Desvignes: This study is the result of a collaboration at NYU Langone Medical Center, between the laboratories of Dr. Stefan Feske and Dr. Joel Ernst, my mentor. Dr. Feske and colleagues had developed a mouse model of rare, inherited mutations he had identified in infants. These mutations occur in the genes for STIM1 and ORAI1, which are crucial for calcium flux in cells of the immune system. The young patients affected by these mutations suffer from severe, recurrent and chronic infections that often cause death before their first birthday. In particular, some of these patients cannot control infection with BCG, which is a normally innocuous strain of mycobacteria administered to protect against tuberculosis (TB). TB is a chronic infection and one of the leading causes of infection-related death worldwide. Going into this study, Dr. Feske and colleagues knew that without functional calcium channels, immune cells do not function properly. However, they did not fully understand how these channels contribute to immune responses to infectious pathogens in a living organism and in particular, for pathogens that cause chronic infections such as TB. This is why Dr. Ernst and I collaborated with Dr. Feske and provided him with our clinical and research expertise in TB. MedicalResearch: What are the main findings? Dr. Desvignes: Dr. Feske’s mice are genetically engineered to lack STIM1 in a certain type of immune cells, known as T cells or T lymphocytes. We infected these mice with Mycobacterium tuberculosis, the bacterium causing TB. Mycobacterium tuberculosis causes chronic infection by manipulating the immune system even in healthy people. The first very surprising result of our study was that mice lacking calcium flux in T cells handled acute TB fairly well. Only during the chronic phase of infection did they become unable to control mycobacterial growth and developed a strong inflammation in their lungs, which was due to an infiltration by different types of immune cells, including T cells. We discovered that the accumulation of STIM1-deficient T cells in the lungs resulted from the cells’ inability to die, which is a normal mechanism to limit an immune response and prevent excessive inflammation. Another immune control mechanism that failed in the absence of STIM1 is mediated by a subset of T cells called induced regulatory T cells, or iTreg cells. These cells are essential to prevent normal immune responses from going “overboard” by suppressing the functions of other immune cells, including T cells. We found that calcium signals are required for the development of iTreg cells and that their numbers were strongly reduced in the lungs of infected STIM1-deficient mice. We therefore think that the lack of iTreg cells in the absence of STIM1 contributes to the severe lung inflammation in chronic TB. The third finding that really surprised us was that T cells accumulating in the lungs of STIM1-deficient mice produced large amounts of a protein called interferon gamma. While interferon gamma is required to control Mycobacterium tuberculosis, it is also a very potent promoter of inflammation and too much of it can lead to tissue damage. Dr. Feske and colleagues had previously observed that calcium fluxes promote the production of interferon gamma in T cells cultured in vitro and we expected the STIM1-deficient T cells to be defective in the production of that protein. During chronic TB, however, calcium signaling turned out to be not only dispensable for the production of interferon gamma by T cells but it was actually required to limit its production and thus, to control inflammation.

Author Interviews, HIV, Nature, Scripps / 04.03.2015

Dr. Michael Farzan PhD Vice Chairman Department of Immunology and Microbial Science Florida Campus The Scripps Research InstituteMedicalResearch.com Interview with: Dr. Michael Farzan PhD Vice Chairman Department of Immunology and Microbial Science Florida Campus The Scripps Research Institute Medical Research: What is the background for this study? Dr. Farzan: The key points are that HIV-1 needs two receptors – CD4 and CCR5 – to infect cells.  CD4’s primary job is to initially bind the viral entry protein, which upon CD4 binding, uncloaks its CCR5 binding site.   A number of years ago we observed that CCR5 had an unusual modification that was really important to HIV-1.  We later showed that antibodies – protein your body makes to protect from pathogens – mimics CCR5 by incorporating this modification.  We develop a peptide from one of these antibodies that mimics CCR5. Medical Research: What are the main findings? Dr. Farzan: By combined a soluble form of CD4 with this CCR5-mimicking peptide, we created a protein that neutralizes all HIV-1 isolates tested, including the hardest-to-stop viruses, as well as distantly related viruses found in monkeys.  It does so better than the best HIV-1 antibodies.  We expressed this protein using a commonly used gene-therapy vector, and showed that after a one-time inoculation we could protect from doses much higher than most humans are likely to see, and we did so 34 weeks after the inoculation.

Author Interviews, Dermatology / 28.11.2014

Univ.-Prof. Dr. med. Tilo Biedermann Klinikdirektor Klinik und Poliklinik für Dermatologie und Allergologie der Technischen Universität München Biedersteinerstr. MünchenMedicalResearch.com Interview with: Univ.-Prof. Dr. med. Tilo Biedermann Klinikdirektor Klinik und Poliklinik für Dermatologie und Allergologie der Technischen Universität München Biedersteinerstr. München Medical Research: What is the background for this study? What are the main findings? Prof. Biedermann: The skin is constantly exposed to microbes and skin developed during evolution under the constant influence of microbes. Tightly regulated communication between microbes and the skin can be expected and levels of regulation still needed to be explored. We found that Gram-positive bacteria when sensed by one certain innate immune receptor (hetero dimer TLR 2-6 suppresses immunity both in animal models and in humans. Following the sensing of lipoproteins by toll like receptor 2-6) skin produces high levels of InterleukinL6 that induce the accumulation of so called myeloid-derived suppressor cells. These cells can be found in the blood but also migrate to the skin suppressing T-cell-immunity allowing infections to spread on the skin. (more…)
