Though he notes that some people have severe, medical vitamin C and vitamin D deficiencies — which can lead to swollen, bleeding gums or bone fractures — and for those individuals, vitamin supplementation is a very effective and necessary measure.

A Cochrane review of randomized controlled trials that examined the effects of taking vitamin C supplements daily on the prevention and treatment of the common cold found that taking the supplement every day didn't reduce the incidence of colds.

However, "it did at least reduce the severity and duration of colds," says Dr. John Mafi , an associate professor of medicine in the Division of General Internal Medicine and Health Services Research at the David Geffen School of Medicine at UCLA.

It's not untrue that vitamin C and vitamin D actually can help to support the function of your immune system. Vitamin D helps your body to create an antimicrobial peptide called cathelicidin, which "stops bacteria, microbes and viruses," and "[regulates] the function of your body's T-cells," Mafi says.

Vitamin D supplements have a bit more evidence for their potential benefits. A systematic review of randomized controlled trials published in the British Medical Journal in found that daily intake of vitamin D supplements protected against acute respiratory infections.

Yet, there are many proven ways to strengthen your immune system outside of supplements like vitamin C and vitamin D, Ben-Aderet says. And if you really want to try vitamin C or vitamin D supplements, Ben-Aderet says: "The jury's still mostly out [on their effectiveness], and vitamin supplementation is cheap and mostly harmless.

If you decide to take vitamin C supplements, you should make sure you don't exceed 2, milligrams of vitamin C in a day, Mafi notes. Too much vitamin C can cause stomach issues like nausea and vomiting and kidney stones, according to Mayo Clinic.

Harvard T. Chan's School of Public Health's hub for nutrition information, The Nutrition Source , recommends a dietary allowance for adults 19 years and older of 90 milligrams for men and 75 milligrams for women.

To get vitamin C, you can eat citrus fruits like oranges, grapefruit and lemons, he notes. Certain greens like kale and broccoli also have great amounts of vitamin C. Taking "roughly to international units IUs of vitamin D per day," is a way to safely address a deficiency, Dr.

Jad Sfeir , a Mayo Clinic endocrinologist, told CNBC Make It in August of It's best to find ways to get the vitamin in your diet from foods, Sfeir said, including fortified milk, orange juice or fatty fish like salmon or mackerel.

Having more than 4, IUs per day can increase your risk of toxicity, by greatly elevating the amount of calcium in your bloodstream and urine, Sfeir noted. Sign up for our new newsletter! Get CNBC's free Warren Buffett Guide to Investing , which distills the billionaire's No.

Immune boosting supplements -

Several studies suggest that low zinc levels can increase the risk of viral infections. Some also show that zinc lozenges may shorten the duration of the common cold.

However, identifying the best dosages for supporting immune health and treating colds will require further research. We know that they play a key role in helping maintain a healthy balance of bacteria in the gut, and new research supports the idea that they have beneficial effects on immunity.

For example, one study from — carried out, it must be noted, by a company that produces probiotics — found that probiotic use may reduce the incidence and duration of upper respiratory infections.

The authors call for more research to establish a relationship between probiotics and the immune system. Many people are taking one or a combination of supplements to prevent or treat COVID But there is not enough data to support the use of any vitamin, herb, or other supplement to treat or prevent this illness.

Only vaccines , together with strict hygiene measures , are proven to help prevent COVID For severe cases of COVID, doctors may use specific medications.

Research does suggest that supplementation with vitamins and minerals can be a low-cost way to support optimal immune function. Even supplementation with vitamins C and D above the current RDAs may be beneficial to the immune system, as long as dosages stay below the recommended safety limits.

Many supplements can interact with medications and other supplements. And combining different supplements can also lead to very high amounts of certain nutrients in the body, which can have potentially severe side effects.

For example, excess vitamin C is excreted in the urine and usually causes no serious side effects. But very high amounts can cause diarrhea , abdominal pain, and nausea. Too much vitamin D — more than 4, IU or mcg — can be harmful and lead to nausea, vomiting, kidney stones , confusion, loss of appetite, and muscle weakness.

Very high levels can even lead to kidney failure, an abnormal heartbeat, and death. Vitamin D also interacts with medications, such as the weight loss pill orlistat Alli, Xenical , steroids , and cholesterol-lowering statins.

If a person has too much zinc, it can cause negative effects such as nausea, vomiting, diarrhea, and headaches. Over time, excess zinc can lead to low copper levels, decreased immunity, and lower levels of helpful cholesterol.

Zinc can also interact with other medications. Probiotics are safe for most people. However, they may worsen illnesses or cause bacterial infections in people who have very weak immune systems or are severely ill.

This can involve :. There is no evidence that mega-doses of vitamins and nutrients can boost the immune system. The best way to ensure that the immune system functions well is to have a balanced diet, get enough sleep, exercise, and take the vaccinations that are offered.

Anyone with nutrient deficiencies who is unable to have a healthy, balanced diet may find it beneficial to take a daily multivitamin. But though some research shows that getting more than the RDAs of vitamins C and D might help support immune health, confirming this requires more research.

If a person thinks they have a nutrient deficiency, they should consider speaking with a doctor about having a blood test. This will help pinpoint any deficiencies and determine the right approach to supplementation. Before taking any supplement, a person should have a conversation with a primary care doctor who is familiar with their medical history.
