The immune system is a large network of cells, organs, and proteins. It helps protect cells from harming microorganisms as well as the toxins.
If the immune system functions at its best, it does amazing job in protecting the body. But having a weakened immune system could increase the risk of delayed wound healing and infectious diseases like colds, and various infections.
Numerous vitamins and minerals commonly referred to by the term “micronutrients,” are necessary for a healthy immune system.
The main micronutrients that play a role in the immune system include:
vitamin A
vitamin C
vitamin D
vitamin E
vitamin B6
vitamin B12
folate
zinc
iron
copper
In ideal circumstances, we’d all get the maximum amount of these micronutrients via an optimum diet that is balanced — but this can be difficult to attain.
A lot of people around the world suffer from nutrient deficiencies. Within the United States, nearly 95 percent of the population is not getting enough of vitamin D. In fact, 84% do not get enough E. Fourteen percent does not receive enough vitamin C, 45% does not receive enough vitamin A, and 15% of people do not receive enough zinc.
Studies have demonstrated that even a small deficiency in one of these vitamins and minerals can result in diminished immunity.
Many factors, such as illness and stress, could increase the loss of nutrient stores within the body.
As we age, our body’s need for micronutrients. People over 50 tend to need more of certain nutrients, including calcium, vitamin D vitamin B6, vitamin B6, and vitamin B12.
In order to maintain an immune system that is healthy and satisfy nutritional requirements one should ensure the diet they consume is balanced and take a multivitamin that includes all of the recommended daily allowance (RDA) of every vitamin.
Many multivitamins might not have enough vitamin C. Researchers believe that
200 milligrams (mg) daily is necessary for immune health.
If a person already suffers from a deficiency that they are suffering from, they may require more of the vitamin than what a multivitamin has.
Some studies have suggested that supplementation with various immune-supporting micronutrients may be beneficial but more research is required.
At present, the strongest evidence suggests that these three micronutrients can provide protection against infection: vitamin C, vitamin D and zinc.
Below, we examine the findings of research on taking supplements with these nutrients.
Vitamin C
Vitamin C ascorbic acid is a soluble water-soluble vitamin recognized for its ability to support a strong immune system. Alongside promoting various cellular functions within the immune system vitamin C aids the body to regenerate and repair tissue, heal wounds, and absorb iron.
Vitamin C has also been identified as an antioxidant, which means that it fights free radicals. It can aid in preventing certain cancers and heart disease.
Studies have shown that vitamin C deficiency can cause an weak immune system and an increased risk of contracting infections.
The human body cannot make vitamin C. It requires food or supplements in the diet.
The RDA for vitamin C is 90 mg.
for adults of males and 75 milligrams for females. Many scientists believe this is not enough . They recommend 200 mg daily to reap the maximum health benefits.
Many studies have shown that vitamin C intake does not prevent colds in the general population however, it can help decrease the symptoms and severity of the symptoms of a cold. A study in 2018 revealed that taking supplementation with vitamin C could help cut down the duration of a common cold by up to half a day, as well in reducing symptoms such as chest pain, a chills, and fever.
Vitamin C supplementation could be more beneficial to people who perform heavy physical activities. In five trials with 598 total participants, who were subjected to short durations of extreme physical stress, vitamin C reduced the risk of getting a common cold by almost 50%.
Vitamin D
Vitamin D plays a critical role in keeping your immune system in good shape so that it can combat viral and bacterial illnesses, such as colds. Some clinical trials suggest the supplementation of 400 internationally unit (IU) 10, or 10 micrograms (mcg), of vitamin D every day could help to prevent common cold.
Other
research has shown that vitamin D treatment can lower the risk of respiratory tract infections, particularly in people with a vitamin D deficiency.
There are some researchers who believe there is a link between vitamin D deficiencies and a higher risk of hospitalizations for COVID-19 although there is some controversy over this theory. In some cases it has been used to reduce the effect of socioeconomic risk factors on at-risk groups.
Many experts think it is likely that the vitamin D intake of 600IU (15 micrograms) for individuals up to 70 years old and 800 IU (20 micrograms) for people over 70 does not provide enough nutrients to support good immune function.
The evidence is unclear, and determining the dose that will best support immune function requires further research.
Zinc
A zinc deficiency could affect the immune system by hindering the development as well as maturation of lymphocytes. They are white blood cells which are an active component of the immune system.
Several studies suggest that zinc levels are low and can raise the risk of viral infections. Some also show that zinc lozenges might reduce the duration of the common cold.
However, finding the right dosages for supporting immunity and fighting colds requires more study.
Many have touted probiotics, or “good bacteria” as another natural way to increase immunity.
We have learned that they are essential in helping maintain the balance of good bacteria in the gut and new research supports the theory that they may have positive effects on the immune system.
One study, for instance, that was conducted in 2020 — conducted by a company that produces probiotics by a company that produces probiotics that the use of probiotics can decrease the duration and frequency of upper respiratory illnesses.
The authors suggest more research to establish a relationship with probiotics as well as the immunity system.
Only vaccinations, in conjunction with strict hygiene measures have been shown to stop COVID-19. In cases of extreme COVID-19, doctors can prescribe certain medications.
The research suggests that supplementing with minerals and vitamins could be an inexpensive way to help support proper immune function.
Supplementing with Vitamins C and D over the current RDAs might be beneficial to your immune system, so long as the doses remain below the recommended safety limits.
Many supplements can be incompatible with medications as well as other supplements. Combining different supplements could also lead to huge amounts of specific nutrients within your body, and this can lead to the potential to cause serious side results.
For example, excess vitamin C can be excreted into the urine, and typically causes no adverse negative side effects. However, excessive amounts of vitamin C can cause abdominal pain, diarrhea, and nausea.
Vitamin D that is too high- more than 4,000 IU or 100 milligramsis harmful and can could cause vomiting, nausea kidney stones, anxiety, loss of appetite, and weakness of the muscles.
High levels of vitamin D can lead to renal failure and an irregular heartbeat and even death. Vitamin D also interacts with drugs, like orlistat, the weight loss pill (Alli, and Xenical), steroids, and cholesterol-lowering statins.
If a person is suffering from too much zinc, it could cause negative effects , such as diarrhea, vomiting, nausea, and headaches. Over time, the excess of zinc may cause lower levels of copper, a decrease in immunity, and lower levels of helpful cholesterol. Zinc can also interfere with other medications.
Probiotics are safe to most people. However, they may worsen illnesses or cause infections with bacteria in people who have very poor immune system or are seriously ill.
Being healthy can boost your body’s natural defenses, and also improve overall well-being. It can be as simple as:
Smoking is not a good idea.
exercising
avoiding excess alcohol consumption, for those who drink
Washing hands often
managing stress well
being up-to-date with recommended vaccines
Maintaining a healthy diet and plenty of fruits and vegetables
being of a moderate weight
getting at least 7 hours of sleep every 24-hour period
There is no evidence to suggest that the massive intake of vitamins and nutrients will boost your immune system. The best way to make sure that your immune system operates effectively is to eat a balanced diet, get adequate sleep, exercise and get the vaccines that are offered.
Any person suffering from nutritional deficiencies and who cannot eat a healthy, balanced diet may find it beneficial to have a daily multivitamin. However, while some studies suggest that getting more than the RDAs of vitamins C and D might help support immune health, the proof will require more study.
If one suspects they may have a nutritional deficiency, they should consider speaking with a physician about getting the blood test. This will reveal any deficiencies and identify the right approach to supplementation.
Before using any supplement, a person is advised to speak with an primary care physician who is acquainted with their medical background.
