Vitamin C Glutathione And Whey Protein

Can Vitamin C help the immune system with COVID-19? Penn State Health Coronavirus

Glutathione is the bodys most important antioxidant. Depletion of glutathione levels through stress and aging has been found to increase the risk of chronic diseases and exacerbate poor immune function. In order to support optimal immunity, the body needs adequate glutathione. This can be accomplished by increasing vitamin C and whey protein in the diet.

Vitamin C is critical for helping the body maintain glutathione levels, protecting the body from illness. Taking vitamin C supplements has been found to increase levels of glutathione in the blood. One study found that 500 mg of vitamin C supplements increased glutathione by 47% in red blood cells.

Vitamin C is also an antioxidant. It is believed that neutralizes free radicals before glutathione, protecting levels of the bodys most important antioxidants. Vitamin C may also help regenerate glutathione, by helping it return to its active form once it has fought off a free radical.

What does this have to do with whey? Whey protein contains the amino acids cysteine and glutamine, precursors to glutathione. Glutathione supplements have not been found to be particularly efficient, so instead taking whey in combination with vitamin C may be the best way to increase glutathione and support immune health.

The Power Of Vitamin C D & Zinc

Vitamin C is one of the most popularly known micronutrients. One of the primary functions of vitamin C is to boost your immunity against immunodeficiencies. Vitamin C is absorbed by our bodies through the consumption of vitamin C-rich foods, such as fresh fruits and vegetables. Our bodies cannot produce, or store large amounts of vitamin C.

Scientific Data On Biochemical Action

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for the normal growth and repair of connective tissue, namely, bone, cartilage, blood vessels and skin.

It is a key for a strong and well-functioning immune.

  • Vitamin C supports the production of interferons.
  • Interferons are produced when the presence of pathogens is detected.

    They facilitate the ability of cells to initiate protective cellular defenses.

  • Vitamin C enhances the function of phagocytes.
  • Phagocytes are a kind of white blood cell that surrounds pathogens and other dangerous particles. Once the intruders are captured, they are digested and neutralized enzymatically.

  • Vitamin C is mainly found in white blood cells.
  • Some of these primary cells of the immune system have levels of vitamin C up to 80 times higher than the levels found in the plasma.

  • Vitamin C supports the cellular immune response.
  • There are 2 main ways that the body can respond to a pathogen: antibody immunity and cellular immunity. The cell-mediated response refers to the activation of macrophages, natural killer cells, and antigen-specific T-lymphocytes that attack anything that is perceived as a foreign agent.

  • Vitamin C enhances cytokine production by white blood cells.
  • Cytokines are communication proteins released from certain white blood cells and transmit information to other cells, thus promoting the immune response.

  • Vitamin C inhibits the apoptosis of various forms of T-lymphocytes.

    Can Taking Vitamin C Prevent A Cold

    Theres been a lot of debate about if vitamin C helps prevent the common cold. Its a topic that has been extensively researched, and theres some evidence that vitamin C may reduce how long your cold may last, says Dr. Radhakrishnan. But he says taking vitamin C on a regular basis doesnt reduce how often youll get a cold or how severe it will be.

    Although the medical evidence is not overwhelming, this vitamin may help reduce the duration of common cold, Dr. Radhakrishnan concludes. This is why some healthcare professionals recommend vitamin C for the common cold.

    Given how safe and relatively inexpensive vitamin C is, it may be alright to give your child a short course of vitamin C during a cold but this should be discussed with your childs physician, he says.

    Effects Of Ia Of Vitamin C On Mortality

    The Right Supplements For Your Immune System

    Of the critical outcomes considered the potential effect of vitamin C on mortality rates appears to be the most controversial one, with RCTs studies that underline promising results which are not supported by recent meta-analysis. A significant reduction of 28-day mortality during ICU hospitalization was observed in a small group of patients with sepsis treated with IA of vitamin C compared to the control group . More recently, findings from the CITRIS-ALI study showed a reduced mortality at day 28 in the vitamin C group compared to the placebo group . Conversely, according to the meta-analysis of Zhang and Jativa, although vitamin C IA seems to be linked to positive vasopressor effects, temporally reducing the need for mechanical ventilation, no positive effect in favor of overall mortality emerged , leading the authors to conclude that it does seem improbable that vitamin C, considered as a single agent, could be so dramatically decisive on the physiopathology of a critical illness as to influence the incidence of mortality . Similar conclusions were drawn by Wei et al. , who, by including recently published retrospective studies in their meta-analysis, suggest the lack of benefit on 28-day mortality, both in ICU and in-hospital patients with sepsis.

    Vitamin C Insufficiency Conditions

    Numerous environmental and health conditions can have an impact on vitamin C status. In this section we discuss examples which also have a link with impaired immunity and increased susceptibility to infection. For example, exposure to air pollution containing oxidants, such as ozone and nitrogen dioxide, can upset the oxidant-antioxidant balance within the body and cause oxidative stress . Oxidative stress can also occur if antioxidant defenses are impaired, which may be the case when vitamin C levels are insufficient . Air pollution can damage respiratory tract lining fluid and increase the risk of respiratory disease, particularly in children and the elderly who are at risk of both impaired immunity and vitamin C insufficiency . Vitamin C is a free-radical scavenger that can scavenge superoxide and peroxyl radicals, hydrogen peroxide, hypochlorous acid, and oxidant air pollutants . The antioxidant properties of vitamin C enable it to protect lung cells exposed to oxidants and oxidant-mediated damage caused by various pollutants, heavy metals, pesticides, and xenobiotics .

    How To Choose A Supplement

    The FDA licenses various supplements. However, some of them are not held to the same safety standards as pharmaceuticals. Therefore, if you wish to take a vitamin C supplement, you should ensure that its a high-quality one bought from reliable sources.

    People Under Heavy Physical Stress

    Some authors have reported a high incidence of respiratory infections in military training centers, probably also due to an overcrowding of individuals often coming from different geographical areas . More data are available on athletes, for whom daily high-intensity training and competitions have been associated with transient immune perturbations, inflammation conditions, and increased susceptibility to infections . Furthermore, compared to the general population, athletes have a higher exposure to pathogens, due to frequent travel and sports events , which may potentially increase the risk of developing viral infections.

    Data in literature referring to the effect of vitamin C supplementation on the prevention of the common cold in these subjects are interesting, despite being limited at present. As was well described by Hemilä and Chalker, vitamin C supplementation may decrease the incidence of colds by about 50% in people under extreme physical stress. More recently, Kim et al. carried out a large randomized, double-blind, placebo-controlled trial in 1,444 Korean soldiers, 695 of whom received vitamin C for 30 days. They showed that the vitamin C group had a 0.80-fold lower risk of getting the common cold compared to the placebo group .

    Support Your Immune Function With Good Nutrition

    One of the most valuable things you have is your health. As a dietitian, I have received numerous queries about recommended foods, supplements and diet patterns to boost immune function. While it is true that nutrition plays a large role in immune function, diet recommendations for the prevention of acute illnesses, like COVID-19 and other viruses, don’t look a whole lot different than general guidelines for healthy eating.

    I’ll start by saying that the concept of boosting the immune system through diet is flawed, as boosting refers to something that is stimulated above the normal level. A good diet cannot boost the immune system, but it’s important to maintain a functional immune system by avoiding immunodeficiency due to malnutrition or micronutrient deficiencies.

    It’s important to note that no single food or nutrient will prevent illness. Also, the immune system is incredibly complex and influenced by a variety of other factors, including stress level, age, sleep and other medical conditions.

    A few key micronutrients have been identified as critical for the growth and function of immune cells, including:

    What Is The Best Form Of Vitamin C To Take For My Immune System

    Vitamin C supplements come in different shapes and doses. You can find them as capsules, drops, effervescent tablets, and even chewables and gummies. It turns out that looking for the best vitamin C supplement for the immune system is all about the delivery system. In other words, how effective is the formula at making vitamin C accessible to the body and keeping it from being flushed out?

    Life Extension’s newest vitamin C supplement, Vitamin C 24-Hour Liposomal Hydrogel Formula, is a great example of why liposomal formulas can be more effective at ensuring the body has enough time to make use of ascorbic acid’s health benefits. “It uses a novel delivery system that makes vitamin C available to the body for up to 24 hours and offers up to seven times greater absorption than standard vitamin C,” noted Dr. Wilson.

    The body does absorb most of the vitamin C in conventional formulas, but you need to take it throughout the day if it’s not in liposomal form, rather than being “one and done.” Why? As Dr. Wilson explained, conventional vitamin C formulations won’t help maintain enough plasma concentrations to allow the body to use it before it’s been flushed out.

    Whichever brand or formula you choose, the secret to choosing high-quality supplements is to look for formulations that are clinically studied for optimal results. “When you purchase a supplement, you have to make sure you choose a reliable and transparent company,” Dr. Wilson added.
