    Even essential nutrients can interfere with many common medications. If you take a traditional blood thinner like warfarin, just the small amount of vitamin K in an MVM can cut its strength. Taking more than 1,000 mg of vitamin E per day can raise your risk for bleeding. And if you take thyroid medication, taking calcium, magnesium, or iron within 4 hours can cut its strength. Ask your doctor about how best to time it.

    Why I Don’t Take Vitamin D Anymore

    I dont take vitamin D. I used to before I learned more, but since I get my vitamin D tested every year, Ive found that with just minimal sun exposure , my vitamin D levels are optimal, year after year, even at Utahs northern latitude where, compared to Florida, sunshine is scant much of the year.

    Also, D can be toxic when consumed in excess, as is common with fat-soluble vitamins. Did you know that either ergocalciferol or cholecalciferol is actually the main ingredient in the category of rodenticides known as hypercalcemia rat poison?

    They work by dosing the rats with significantly more vitamin D than the tiny amount they need , which elevates blood calcium to a lethal level . Symptoms of excess serum calcium are the same as symptoms of rat poisoning.

    The Resources section at the end of this article includes a couple of links on this topic if you check them out, Im pretty sure youll learn a few things!

    If you eat animals, its easy to get vitamin D second hand, from food. For plant-exclusive folks, look to sunlight, sun lamps, or mushrooms if you want to avoid supplements and synthetically fortified foods.

    Youll have to read up on these topics. For example, you have to set your mushrooms outside in the sun or under a sun lamp to bathe in UVB rays. And youll need to learn some things about sun lamps .

    The appeal of safe, natural treatments is undeniable. Its true for age-old conditions such as the common cold, and for new diseases, especially if they have no known cure. So it makes sense that there would be a lot of interest in supplements for COVID-19, whether as prevention or treatment.

    The Role Of Vitamin D In The Immune System

    Adequate vitamin D levels in the body can be achieved by sufficient vitamin D consumption and sun exposure. The risk factors for vitamin D deficiency are age, smoking, obesity, and chronic diseases such as diabetes and hypertension . 25-hydroxyvitamin D levels were inversely correlated with acute respiratory infection, as reported in the National Health and Nutrition Survey 20012006 . Sufficient concentration of 25-hydroxyvitamin D was associated with a reduction in the risk of acute respiratory tract infections in adults . In addition, sufficient levels of 25-hydroxyvitamin D in the serum were inversely correlated with the risk of viral respiratory tract infection in children . Moreover, there was a small case study conducted with 10 COVID-19 patients in Indonesia . On blood analysis, nine patients had vitamin D deficiency, and one patient had insufficient levels of vitamin D. Therefore, there was no patient with adequate vitamin D levels in the study. This indicates that vitamin D deficiency might be a risk factor for viral infection.

    Vitamin D modulates helper T cell responses. It reduces T helper type 1 immune responses and induces Th2 responses . Th1 cells produce pro-inflammatory cytokines, such as IFN- and TNF-, while Th2 cells produce IL-4, IL-5, IL-10, and IL-13 . As vitamin D induces a shift from Th1 to Th2 phenotype, it decreases Th1 cytokines but increases Th2 cytokines .

    Other Effects Of Vitamin C

    Food as Medicine – Sources Of Vitamin C, D, Polyphenols, Zinc, and Quercetin

    Vitamin C’s collagen-boosting property keeps other tissues — including your skin, connective tissue and blood vessels — strong and resistant to damage. Low vitamin C levels reduce your body’s collagen levels, causing skin tearing and tooth loss. Vitamin C keeps you energized by helping your cells derive useable fuel from fat, supports brain function by aiding in the production of brain communication molecules and helps control your blood cholesterol levels. It also functions as an antioxidant, protecting you from free radicals that age your cells and contribute to disease.

    If You Take Iron Supplements

    You absorb iron best on an empty stomach. Take it with water or, better yet, a citrus juice: Iron and vitamin C have a tag-team effect. If it makes you queasy, save it for right after a meal. But donât mix it with calcium or high-calcium foods — these interfere with iron. You wonât take in either one fully. Men and postmenopausal women should skip supplements with this mineral unless a doctor says otherwise. The average MVM has more than you need.

    Why Experts Say You Should Be Taking Vitamin C Vitamin D3 And Zinc

    While the warmer months promote the proliferation of bugs , the colder months can encourage the spread of other kinds of bugs .

    Though theres no surefire way to avoid getting sick, enhancing your immune system is a smart place to start. Vitamins, essential minerals, and other nutrients are needed by the immune system to help protect your body from billions of potentially harmful bacteria, viruses, and other germs.

    Some home remedies that support healthy immunity include such staples as garlic, ginger, and echinacea. But these arent essential for the immune system to work. Recent research has underscored the potential synergetic effects of essential nutrients such as vitamin C, vitamin D3, and zinc in supporting the immune system.

    Lets take a closer look at the benefits of this potent vitamin/mineral trio.

    Vitamins Might Offer Immune Support But They Don’t Treat Covid

    Scientists often study zinc, vitamin C, and vitamin D in relation to viral infections.

    Some research suggests that zinc might prohibit viruses from replicating, and populations at high risk of acquiring viruses like HIV or hepatitis C are often deficient in zinc. Vitamins C and D also have anti-inflammatory properties that may help ward off severe disease.

    Based on this knowledge, Beran said, some countries have promoted “vitamin cocktails” for COVID-19. Early in the pandemic, Egypt required doctors to prescribe vitamin D, vitamin C, and zinc to symptomatic COVID-19 patients.

    “At that time, there was no enough evidence for that, but they just made this conclusion based on non-COVID data,” Beran said.

    As of August 2021, Egypt’s COVID-19 treatment protocol still included zinc and vitamin C. India also commonly prescribes vitamin C, vitamin D, and zinc for COVID-19, according to a June 2021 editorial in The Lancet.

    But the National Institutes of Health has found “insufficient evidence” to support vitamin C, vitamin D, or zinc as COVID-19 treatments.

    Beran said some patients in his Ohio clinic still believe vitamins will improve their COVID-19 symptoms.

    There’s no evidence for those beliefs, either: A February 2021 study found that zinc and vitamin C supplements neither reduced COVID-19 symptoms nor led to faster recovery.

    What Is The Difference Between Vitamin D And Vitamin C


    Posted by Wen Dan Jiang on

    The human body requires these two vital vitamins as part of our daily routine. For this, it is good to be aware of the sources from where we can get them. Instead of taking pills, food sources are always preferred.

    • 4-8 years old: 1,000 mg
    • 9-18 years old: 1,300 mg

    We all have heard that excess of anything is bad. Consuming these two vitamins in the right quantity is important. The following side effects may occur if consumed more than the quantity mentioned earlier.

    Final Word

    The above-mentioned differences prove that both vitamins C and D act differently in the body, yet play a significant role in sustaining a healthy body. Not only vitamin D or C, each and every vitamin is essential for healthy growth and sustenance. The golden rule is to have a balanced diet because, in this modern era where junk food has a global impact and is ruining health, including children’s, only nutritious food can save us.

They include C and the Bâs: thiamin , riboflavin , niacin , pantothenic acid , pyridoxine , biotin , folic acid , and cobalamin . Take them with or without food, with one exception: Youâll absorb B12 better with a meal. If you also use vitamin C, put 2 hours between them. Vitamin C can keep your body from using B12.

    What Are The Health Benefits Of Vitamin C

    Vitamin C is most commonly known for its ability to support the immune system and its immune health benefits have long been studied by researchers and scientists. While evidence is mixed, most of this research on vitamin C points to positive benefits on the immune system. One meta-analysis reviewed 60+ studies on the effect of vitamin C on the common cold and concluded that while vitamin C does not help prevent colds in normal adults, it may help support healthy immune function.

    Vitamin C is considered a potent antioxidant involved in sequestering free radicals to minimize the damage they cause to our bodies due to oxidative stress. Vitamin C is also well known as a helper vitamin for Iron. Research has shown that taking vitamin C can help our bodies better absorb iron from food or supplements.

    Fun fact: In the 1700s, scurvy was a common problem for sailors on long trips out at sea and in 1747, a Scottish Naval surgeon, James Lind, discovered citrus fruits, high in vitamin C, can help prevent scurvy.

    You Get More Vitamin C From Foods Than Supplements

    It’s Time To Boost Your IMMUNE System – Vitamin C, D, & Zinc Rich Foods

    Fascinating fact: In a 2000 study in the journal Nature, Cornell Professor Rui Hai Liu and his team showed that just a half cup of apple contained the vitamin-C-like activity equivalent to 1,500 milligrams of vitamin C , But when they analyzed that small portion of apple, they found just 5.7 milligrams of vitamin C in it!

    Did you catch that? You might want to read it again. Its important, if youre spending hundreds of dollars on supplements, to think about how science knows little-to-nothing about how bioavailable nutrients arefrom FOOD. Isolated synthetic supplements, not so much.

    In his book Whole: Rethinking the Science of Nutrition, author T. Colin Campbell discusses the significance of this groundbreaking study:

    The vitamin-C like activity from 100 grams of whole apple was an astounding 263 times as potent as the same amount of the isolated chemical! Said another way, the specific chemical we refer to as vitamin C accounts for much less than 1 percent of the vitamin C-like activity in the apple a miniscule amount. The other 99-plus percent of this activity is due to other vitamin C-like chemicals in the apple, the possible ability of vitamin C to be much more effective in context of the whole apple than it is when consumed in an isolated form, or both.”

    Look For Quality Checks

    Since the FDA doesnât regulate supplements, look for brands that have been âverifiedâ by one of the three companies that test supplements in the U.S.: Pharmacopeia, Consumer Lab, or NSF International. These testing organizations verify that whatâs on the label is in the bottle in the right amounts.

    The Advantages Of Taking Vitamin D And C

    Vitamins D and C play a part in keeping you healthy by promoting strong bones and tissues. However, evidence casts doubt on the idea that they can actually prevent serious diseases in adult life or even minor ailments such as the common cold, according to the University of Maryland Medical Center. The most effective way of ensuring that your body gets enough of both vitamins is to eat a balanced diet. If you are worried that you might be experiencing a deficiency of either vitamin and wish to take supplements, you should seek the advice of your health provider.

    If you are experiencing serious medical symptoms, seek emergency treatment immediately.

    Synergistic Action Of Nutrients On Physical Barriers

    The outer and inner surfaces of an organism, such as the skin and mucous membranes, are the first line of defense against pathogens, toxins and other foreign bodies, as they form physical barriers that prevent entry . SARS-CoV-2 is able to penetrate physical barriers when they are vulnerable. Thus, it can be transmitted directly, when there is physical contact with the infected person, or indirectly, when the infection occurs through droplets and aerosols in suspension or through fomites, where steel and plastic are the materials in which this virus is more viable .

    Droplets containing SARS-CoV-2 are transmitted when they come in contact with the oral, respiratory tract and intestinal mucosa and the conjunctiva, tissues that express ACE2 necessary for the entry of this virus into the body. However, whether the consumption of food contaminated with SARS-CoV-2 can cause its transmission through the digestive system remains to be confirmed . Thus, the physical and functional integrity of the physical barriers, especially epithelial cells, is important for reducing the risk of SARS-CoV-2 contagion.

    The epithelial cells are joined by distinct intercellular junctions, known as the epithelial junctional complex, which is formed by tight junctions, adherens junctions and desmosomes . Because they act as a selective barrier, this complex prevents the entry of pathogens and toxins into the bloodstream.
