The Science Behind Vitamin A And Immunity
Vitamin A strengthens both the innate and adaptive immune systems of the body. The innate immune response protects the skin, eyes, respiratory tract, gastrointestinal tract and reproductive organs. The adaptive immune system produces antibodies that attack foreign invaders . Carotenoids are also powerful antioxidants that help the body fight inflammation. Like most nutrients for immune health, the best way to get your vitamin A is from food, rather than supplements.
Vitamin A supplementation is especially prone to causing toxicity, and over-supplementation can actually weaken the immune system. The good news? Food sources of vitamin A are safe and effective for meeting your daily needs. Plus, they’re colorful and delicious!
Benefits Of Cranberry Supplements
Cranberry supplements may help prevent and treat urinary tract infections, help strengthen your urinary tract walls, and support your overall immune system so you’re at a lower risk of infection. Cranberry naturally contains high levels of antioxidants that help fight free radicals and their oxidative damage. It also contains vitamin C which is known for its immune-boosting properties.
Some brands add vitamin C and other micronutrients to further enrich their products and help protect your overall health and well-being.
Vitamin A And The Immune System
Vitamin A contributes to the maintenance of the normal function of the immune system and the maintenance of normal mucous membranes. These membranes are found on the linings of the nose, mouth, lungs, and stomach, and such form an important barrier for the body.
The best food sources of vitamin A include liver , orange and yellow vegetables, such as carrots, sweet potatoes and pumpkins, tomatoes and leafy green vegetables, such as kale, spinach and broccoli.

The Truth About Immune
Increasing your intake of zinc and vitamins C and D during winter isnt a magic bullet. Heres what the science says about the most commonly touted interventions.
To guard against a winter rise in respiratory infections, some people boost their immune system with supplements and nutrient-rich foods. For a subset, that is in addition to social distancing, masking, and flu and COVID-19 vaccinations, which reduce the risk of getting an infection or developing severe symptoms for others its their sole defense.
Theyre hoping to use minerals like zinc and vitamins including C and D to amp up the immune response in case an infection strikes. Although such efforts are unlikely to prevent an infection, they could support a persons immune system. But for an average person who eats well, exercises, and gets enough sleep, supplements may not do a whole lot, says immunologist Scott Read at Australias Western Sydney University, unless they’re deficient.

Instead, a balanced diet and healthy lifestyle factors such as good hygiene and adequate exercise provide more than sufficient support for your bodys immune system.
However, this is not always the case. For some children, vitamin supplements can be beneficial. Here are some of those exceptions:

Three Vitamins Minerals To Boost Your Immune System And Fight Covid
Associate Professor of dietetics and nutrition shares which supplements and food groups can help keep you healthy
As we continue to keep an eye on COVID-19 and its new strains, now is a great time to strengthen our immune systems to combat the virus.
According to Associate Professor of dietetics and nutrition Cristina Palacios, supplements and foods rich in certain vitamins and minerals are crucial.
Those of us that have a better nutritional status can fight the disease better than others, says Palacios, a faculty member at the Robert Stempel College of Public Health & Social Work. We constantly have pathogens, such as virus and bacteria, coming into our bodies. If our immune system is working really well, we dont get infected.
She adds, In general, nutrition affects our entire body. All body processes require enzymes, and many vitamins and minerals help enzymes work better. Theres the saying, We are what we eat. Its true. If you want to be healthy, you have to consume certain nutrients.
So, how do we keep our immune systems healthy during this time?
To shed light on the matter, Palacios recently hosted a free virtual webinar for the community. The webinar was part of an ongoing series organized by Palacios and a team of graduate students to share information with folks who are trying to keep their families healthy.
Here are the top three supplements adults should consider taking.
Nutrients through food

Can Supplements Help Boost Your Immune System
As outlined above, supplements are not a substitute for a balanced diet and a healthy lifestyle. The body can absorb and regulate its requirement for vitamins and minerals more easily from food sources. Not all vitamin and mineral formulations are equal. Some iron supplements for example may cause side effects such as bloating, constipation or stomach upset.
Other nutrients are best absorbed in food form for safety reasons, vitamin E for example is not recommended for those on certain blood thinning medications. While others such as probiotics in theory can help with gut function which may improve your immune health overall but lack the research to prove their effect on improving your immunity.
If for some reason you find that you are unable to meet your bodys need through food alone then you may decide to supplement some or many of the immune supporting vitamins and minerals your body needs e.g. Vitamin C, Vitamin D, Iron and Zinc.
Zinc For Immune Support
Zinc is an essential nutrient important for the daily maintenance of your bodys natural defenses. Our bodies dont store zinc, so we need a daily dose.
Many foods are rich in zinc, including meats, shellfish, legumes, seeds and dairy. But if you find it difficult to get enough of them or dont have a strong appetite, consider a supplement.
A daily serving of Nutrilite Immunity Defense Zinc + Holy Basil supplies 20mg of zinc. It also includes 400mg of holy basil, which is a sacred plant in Traditional Ayurvedic Medicine. Research shows that holy basil supports your respiratory health and promotes healthy immune function.

Cant Get To The Farmers Market Buy The Frozen Stuff
There is a myth that frozen fruits and vegetables are useless, and that only fresh local produce can give you the right immunity boost. While we support preparing food from as many fresh ingredients as possible, we also want you to keep in mind that theres nothing wrong with some frozen choices. Why? Because they are generally frozen when they reach their peak ripeness, which means they retain their nutritional value. Just make sure you dont go for packets with added sugar or salt!
Immune Support Supplements: Zinc
For maximum immune health support, turn to zinc. As you age, your zinc levels decline, making it harder for your body to defend itself against challenges. That’s why zinc is an especially crucial immune health supplement for the elderly. No matter what your age, though, this mineral is a must-have if you’re concerned about staying well!

What Vitamins Support Your Immune System
Vitamins are one of natureâs necessities. Not only do they build strong bones, teeth, hair, and skin, but they help prevent the common cold, flu, or other diseases from taking hold of our bodies. Of course, knowing which particular vitamins offer what type of immune support is key.
A multivitamin will typically deliver your daily dose of nutrients, or you can shop for vitamins separately based on what your body needs. Here are some essential vitamins and minerals:
- Vitamin A: an infection-fighter, this plant carotenoid supports healthy eyes and skin
- Vitamin B6: immune and cognitive function support that regulates your sleep and appetite
- Vitamin B9 : a prenatal vitamin for healthy cell growth and function
- Vitamin B12: helps keep your blood and nerve cells healthy
- Vitamin C: an important immune support vitamin your body needs daily to fight infection
- Vitamin D: a disease-fighting essential your body typically converts from the sun

Immune System Your Bodys Defense Mechanism
The immune system is our natural defense mechanism against environmental factors. Its made up of a network of cells, molecules, tissues and organs that work together for the benefit of your health.
It includes physical barriers like your skin or your saliva and tears that wash intruders away. It also includes white blood cells and other internal mechanisms that jump into action to support your health when needed.
And something that may be surprising, it also includes your gut. A whopping 70% of your immune system is located in your gut, which is also home to trillions of tiny good and bad bacteria. Thats called your microbiome.

Best Vegan Immune Formula: Megafood Immune Defense
For this immune supplement, MegaFood recommends consumers take two tablets three times a day for five days, when you need more intensely focused immune care and support. In their words, “when you need it most.” If you take this product at their recommended frequency, you’d be getting 750 mg of vitamin C a day, 15 mg of zinc bisglycinate daily, and potent doses of three botanicals , too. This vegan supplement is also GMO-free, gluten-free, dairy-free, soy-free, and Kosher. However, in my opinion, excluding vitamin D3 in an intensive immune formula seems like a miss. And while designed for short-term use, it does require some dedication .*
Stress And Immune Function
Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress. Despite the challenges, scientists are actively studying the relationship between stress and immune function.
For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another. When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person’s subjective impression of the amount of stress is accurate. The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors.
Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one’s work. Some scientists are investigating whether ongoing stress takes a toll on the immune system.
Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress.

What Can You Do To Boost Your Immune System
The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don’t know about the intricacies and interconnectedness of the immune response. For now, there are no scientifically proven direct links between lifestyle and enhanced immune function.
But that doesn’t mean the effects of lifestyle on the immune system aren’t intriguing and shouldn’t be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans. In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.
Immunity in action. A healthy immune system can defeat invading pathogens as shown above, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them .

Vitamins And Boosting Your Immune System The Truth
Most people would like to know what vitamins and minerals boost our immune system, thinking that certain foods and drinks can drastically increase our bodies ability to fight off harmful microorganisms. However, scientists doubt there is much we can do to actually give our immunity a boost, which would mean that our defence against diseases would be working in overdrive. Instead, they argue that we can only help it to function to the best of its abilities.
But what do they mean?
Well, your immune system consists of a vast network of cells, tissues and organs, constantly standing guard and detecting unwelcome substances.
When this system recognises foreign tissues, it attacks and destroys them for our own good. But to be able to keep doing so every time when our body is under threat, all of its parts must work together like a well-tuned machine. And this is only possible if we sustain healthy habits that dont interfere with any of the major players in this immunity network, causing a weak immune system.
