Which brand. Start now or wait till symptoms?
I picked one based on ratings
Resveratrol doesn’t work long term without 30mg zinc.
I also noticed extra virgin olive oil helped. Probably the polyphenols are antiviral.
Keeping the carbs low and staying away from technology to keep cortisol levels low is very important.
Taking 500mg Niacinamide and accidently eating aflatoxins from nuts made things worse.
I believe I still have a viral load. It’s been up and down. Feel great and then feel sick again. Weird.
My diet has creeped from around 25 grams net carbs to 57. I exercise 2 hours a day, a mix of walking, airbike, resistance training that burns 1,000+ calories above my 1700 calorie RMR. I want to believe the reletively high amount of activity compensates for the extra carbs. Am I right?
Since we have the virus to think about I’ve wondered about the impact of exercise on the immune system and found this.
Watch Queen Elizabeth’s address to the UK, inspiring, reminds me of why I’m so fond of the British.
Sunshine is required to gain long term immunity against viruses.
Thanks for sharing this. This connection found between light exposure and human immune response is fascinating!
The one thing that stumped me, though, was the final sentence of the Abstract… if non-polarized light reduced “IC” (immune content) more than polarized light, then, given that direct sunshine is largely non-polarized light (unlike artificial surface reflections of sunlight, which often produce polarized light), what does this study imply for direct sunshine’s effects on our immune systems?
I’m pretty sure it’s both polarized and non-polarized depending on time of day and cloud coverage. 9-11am and 4pm onwards being the healthiest from my experience.
I find starring into this phone is making me sicker because it’s non-polarized.
I believe people who are sick should open their curtains during this pandemic. How else do bats gain immunity against these viruses?
… I think most bats generally hide from the sunlight. They’re nocturnal
I’m seeing some sleeping on trees. Maybe some aren’t? Maybe those sleeping in caves have a reversed biology to ours?
Vitamin D Plus Zinc And Vitamin C:
I’ve taken all those supplements for weeks and they do help to an extent but I’m not gaining long term immunity with my light/infrared blocking curtains closed.
Interesting regarding the Vitamin C. Thanks for sharing. I’m going to increase my acerola extract intake.
I think there are multiple reasons why people who are insulin resistant or metabolically deranged would be more susceptible to COVID-19. I wondered in another post if one reason is that an immune response could demand more glucose, and for someone who is insulin resistant, their ability to efficiently utilize glucose is impaired. That ability would probably be further impaired by the added stress of their body trying to fight off an invading virus. Here is the link to those posts:
To take this a step further, Dr. Saladino’s podcast with Dr. Stephen Hussey mentioned a study noting that T cells and other immune cells have insulin receptors that mediate their stimulation and that these immune cells have the potential to become insulin resistant. This would mean that an immune response would possibly be less effective in someone who is insulin resistant because their immune cells would not be able to effectively use glucose (or fat for that matter). That immune response would probably also demand more glucose and more insulin than it should, which could contribute to a cascade of detrimental effects.
I think there is another reason why coronavirus, or viruses in general, might be more detrimental to people with insulin resistance. I’ve been hearing Thomas DeLauer talk about how a virus is more likely to thrive in an environment where more glucose is present and a bacterial infection is more likely to survive when the predominant fuel source is fat. If we think of insulin as a lever that switches your body to using glucose rather than fat, in someone with insulin resistance with high insulin levels, there is going to be more glucose present in their body and more fuel for the virus.
For someone who is on a ketogenic diet I think the best way to help your body out if it is fighting a virus like this is to increase protein consumption while limiting carbohydrate consumption as much as possible. The protein would supply enough glucose to fuel the immune system’s fight against the virus while not causing too much of an insulin spike. In someone with a very healthy metabolism they might benefit from eating more carbs to help fuel the fight against the virus, but for most people who are insulin resistant I think carbs would just put more stress on an already stressed system.
This medication is usually used for arthritis (inflammation) or bone cancer patients but supposedly has some bad side effects long-term but short term (a very small intravenous dose?) for a viral induced pneumonia, might prove useful?
According to the bio-hackers (#chaga) out their Vitamin C and Zinc with a little D throat lozenges can prevent (viral overload) the virus from making a person with an impaired immune (function) system critically ill if exposed?

Children are largely unaffected by COVID-19, remaining disease-free or manifesting few or mild clinical signs and symptoms. Understanding how the infection affects children is critical to preventing the further spread of the disease. A recent study explored the characteristics and transmission patterns of COVID-19 among children in China.
The study involved more than 2,000 children (average age, 7 years) living in mainland China who had been diagnosed with COVID-19. Children were classified as asymptomatic, mild, moderate, severe, or critical cases, based on diagnostic criteria that included fever, upper or lower respiratory involvement, diarrhea, and other symptoms.
Approximately 4 percent of the children with COVID-19 were asymptomatic cases, and 51 percent and 38 percent were mild or moderate cases, respectively. Among children manifesting symptoms of the disease, only 5 percent had shortness of breath and fewer than 1 percent progressed to acute respiratory distress syndrome (ARDS) or multiorgan system dysfunction (MODS). These figures are in stark contrast to those observed in adults, where shortness of breath, ARDS, and MODS are far more common, especially among older adults.
The data also indicated that children younger than one-year-old were at greatest risk of COVID-19 complications. A commentary on the study’s findings suggested that children who had pre-existing respiratory problems or were immunocompromised were also at greater risk. These findings underscore the need for further research into how COVID-19 manifests in younger patients to improve treatment and prevent disease spread.
The most common symptoms of infection from SARS-CoV2, the virus responsible for COVID-19, include fever, cough, shortness of breath, and indications of widespread respiratory system involvement. Recent evidence suggests that SARS-CoV2 can attack other organ systems, as well. In fact, some infected patients report loss of smell and taste, potentially signaling SARS-CoV2 infiltration of the central nervous system.
SARS-CoV2 exploits the angiotensin-converting enzyme 2 (ACE2) receptor to gain entry into cells. One group of scientists described the expression of ACE2 in neurological tissue and assessed the possible contribution of neurological tissue damage to the death and disease associated with COVID-19.
They noted that long before the neuronal damages occur, the endothelial tissues in cerebral capillaries rupture and bleed into the surrounding tissue, which is often fatal. They suggested that early signs of impaired smell or taste in an otherwise uncomplicated early-stage COVID-19 patient should be investigated thoroughly for central nervous system involvement. They concluded that although widespread homeostatic dysfunction is the primary cause of death among COVID-19 patients, cerebral edema due to neurological damage might expedite death before the onset of homeostatic failure. These findings can influence the triaging of patients with COVID-19.
Sepsis is a potentially life-threatening condition caused by the body’s innate immune response to acute infection. Under some circumstances, aspects of this response that are typically associated with defense against infection can induce extensive cell and tissue damage, leading to multiple organ failure, the hallmark of sepsis. Acute respiratory distress syndrome (ARDS) is a common sepsis-associated organ injury that can lead to respiratory failure and death. A 2019 phase 2 trial found that intravenous vitamin C reduced death rates among patients with sepsis and ARDS.
The randomized, double-blind, placebo-controlled, multicenter trial took place in seven medical intensive care units in the United States over a period of three years. The study participants included 167 male and female patients (average age, 55 years) with sepsis and ARDS. Every six hours for four days, the patients received either intravenous vitamin C (50 milligrams per kilogram of body weight) or a placebo.
The authors of the study noted a substantial difference in the death rates among the two groups. Whereas approximately 30 percent of patients who received intravenous vitamin C died, more than 46 percent of patients who received the placebo died. Patients who received vitamin C also had fewer ventilated days, spent less time in intensive care (seven days versus ten), and their hospital stays were approximately one week shorter than those who received the placebo.
These findings suggest that intravenous vitamin C administration might be beneficial in critically ill patients who have sepsis and respiratory failure.
The bulk of scientific research on the effectiveness of vitamin C in fighting infection has centered on reducing the symptoms and duration of the common cold, with mixed results. Most of these studies have used doses of approximately 1 gram per day, however. Findings from a 2017 study suggest that much larger doses might be more effective at reducing a cold’s duration.
Although most adults typically have only one or two colds per year, cold symptoms are the reason for many lost days of work or school. Some evidence suggests that the financial costs associated with having a cold are similar to those associated with having high blood pressure or a stroke.
The author of the study reviewed the findings of two randomized trials focused on the effectiveness of vitamin C in reducing cold symptom duration. One of the trials had four treatment groups: one group that took a placebo, two groups that took 3 grams per day, and one group that took 6 grams per day. The 6-gram dose reduced cold symptom duration by about 17 percent – roughly twice as much as that observed with only 3 grams. The placebo had no effect on symptom duration. The other trial had three treatment groups: one that took 4 grams per day, one that took 8 grams per day, and one that took a placebo. Taking 8 grams per day reduced symptom duration by 21 percent, compared to the placebo group.
These findings suggest that large doses of oral vitamin C might reduce the duration of symptoms associated with the common cold, but self-dosing should commence as soon as cold symptoms appear for the greatest benefit.
Mechanical ventilation – a therapeutic measure used to assist or replace spontaneous breathing – is an important strategy used to treat people experiencing respiratory failure. A recent meta-analysis found that vitamin C treatment shortened the duration of mechanical ventilation among patients in intensive care.
The investigators looked at the findings from eight trials involving 685 patients. They found that vitamin C shortened the duration of mechanical ventilation an average of 14 percent. But the investigators noted major differences in the effect of vitamin C between the trials, with the greatest benefit, observed among patients who were on mechanical ventilation for the longest duration – the patients who were most critical. In five trials involving more than 470 patients requiring ventilation for more than 10 hours, providing 1 to 6 grams of vitamin C per day shortened ventilation time an average of 25 percent.
These findings indicate that vitamin C shortens the duration of mechanical ventilation, especially among critically ill patients.
Inflammation is a biological phenomenon triggered by the immune system in response to a physical injury or infection. Vitamin C’s immune-boosting and antioxidant properties can mediate the body’s inflammatory response, reducing the symptoms or risk of various diseases. Evidence suggests that vitamin C can lower C-reactive protein (CRP), a marker of inflammation.
C-reactive protein is a protein that increases in the blood with inflammation and infection as well as following a heart attack, surgery, or trauma. It is one of several proteins that are often referred to as acute phase reactants. Blood levels of CRP greater than 1 milligram per liter are indicative of elevated cardiovascular disease risk.
The randomized study involved nearly 400 healthy adults (average age, 44 years) who took 1 gram of vitamin C, 800 international units of vitamin E, or a placebo every day for two months. The findings revealed that vitamin E had no effect on lowering CRP; however, vitamin C supplementation decreased CRP 16.7 percent compared to pre-treatment measurements, but only in participants who had baseline CRP levels above 1 milligram per liter. This reduction in CRP was comparable to those achieved with statins (cholesterol-lowering drugs).
Interestingly, the study identified a strong link between obesity and elevated CRP levels. Whereas 25 percent of normal-weight people had elevated CRP levels of CRP, 50 percent of overweight participants and 75 percent of obese participants had elevated levels.
These findings suggest that vitamin C might decrease inflammation to a similar magnitude as some statins in people at a higher risk of cardiovascular disease based on CRP levels.
Catechins are bioactive compounds present in green tea. Some catechins, such as epigallocatechin gallate (EGCG), are potent scavengers of reactive oxygen species with demonstrated antioxidant, anti-inflammatory, and anticarcinogenic properties in both clinical and in vitro studies. Evidence suggests that vitamin C might increase the bioavailability of the catechins present in green tea.
Consumers of green tea commonly add milk, lemon, or other substances to their tea. To assess the impact that these additives have on catechin bioavailability, the authors of the study added varying quantities of citric acid, BHT and EDTA (common preservatives), ascorbic acid (vitamin C), milk (cow’s, soy, and rice), and citrus juice (orange, grapefruit, lemon, or lime) to prepared tea. Then they subjected the tea formulations to simulated digestive processes and measured the amount of catechins they recovered.
They found that overall, green tea catechin recovery was poor, with more than 80 percent loss of catechins during digestion. Adding milk to tea increased catechin recovery considerably, but the greatest improvements were observed with the addition of vitamin C or citrus juices, the latter of which increased recovery to 98 percent.
Citrus juices contain bioactive compounds that might influence catechin recovery, but they are also rich in vitamin C. These findings suggest that consumption of green tea with vitamin C, especially in conjunction with other bioactive compounds in citrus juices, increases the recovery of the beneficial components present in the tea.
Exercise-induced bronchoconstriction – a narrowing of the airways in response to exercise – occurs in up to 10 percent of the general population and up to 50 percent of some competitive athletes. Findings from a meta-analysis suggest that vitamin C might reduce the incidence of exercise-induced bronchoconstriction.
Previous research demonstrated that vitamin C can triple respiratory tissue levels within an hour or two of a single oral dose of 1 or 2 grams. This local increase in vitamin C concentration appears to protect against acute increases in airway oxidative stress. In addition, vitamin C inhibits the production of prostaglandins and leukotrienes, biological compounds that participate in the pathogenesis of exercise-induced bronchoconstriction. In addition, vitamin C halved the incidence of the common cold among people experiencing heavy short-term physical stress – an indication that vitamin C might also have other effects on people experiencing heavy physical exertion.
The authors of the current study conducted analyses of nine studies that investigated varied aspects of the effects of vitamin C on exercise-induced bronchoconstriction. Three placebo-controlled studies analyzed the relative exercise-induced decline in forced expiratory volume, or FEV1, (a measure of respiratory capacity) with or without vitamin C. These trials found that doses ranging between 0.5 and 2 grams of vitamin C reduced FEV1 decline by half. Similarly, five studies investigated the effects of vitamin C supplementation on respiratory symptoms after short-term heavy physical work and found that incidence was halved. One study investigated the duration of respiratory symptoms in young male swimmers and also found that incidence was halved.
The authors noted that a variety of factors might influence whether and to what degree vitamin C affects respiratory function during exercise, including the type of activity and the conditions under which it is performed, among others.
The human body responds to mental stress by releasing hormones called corticosteroids, triggering the body’s fight or flight response. Chronic activation of these hormones can impair immune function, increasing susceptibility to infection and disease. Findings from an early study in mice demonstrate that vitamin C mitigates the body’s stress response, thereby improving immunity.
The authors of the study immobilized mice for an hour every day for three weeks to induce stress. They also fed the mice 200 milligrams of vitamin C daily – roughly equivalent to several grams per day in humans. A control group of mice also received vitamin C but they were not subjected to stress.
The stressed mice that received large doses of vitamin C in their diets exhibited fewer signs of stress as evidenced by lower levels of corticosteroid hormones as well as other physical manifestations, such as weight loss. The mice also exhibited higher levels of IgG, the most abundant antibody in circulation, responsible for binding a broad selection of pathogens such as viruses, bacteria, and fungi, to prevent infection. Interestingly, the non-stressed mice that received large doses of vitamin C exhibited even greater increases in IgG, suggesting that stress cancels out some of the beneficial effects of the vitamin.
These findings suggest that high dose vitamin C might improve immune function, especially during times of mental and physical stress.
Vitamin C is essential for the synthesis of carnitine, a compound required for fatty acid oxidation – the utilization of fatty acids as energy – commonly referred to as “fat burning.” Carnitine deficiency is associated with fatigue and poor exercise tolerance. Findings from a new study suggest that high doses of vitamin C improves fatty acid oxidation.
The two-part clinical study involved 22 men and women between the ages of 18 and 38 years. Fifteen of the participants had marginal vitamin C blood levels (less than 34 micromoles per liter) and seven had adequate vitamin C blood levels (greater than 34 micromoles per liter).
In the first part of the study, all of the participants completed a 60-minute treadmill walk at 50 percent of their VO2 max. Fat utilization during the treadmill walk was 25 percent lower among participants with marginal vitamin C status, suggesting that vitamin C status affects fuel utilization during exercise.
In the second part of the study, the participants’ vitamin C levels were depleted over a period of four weeks. Then they took either 500 milligrams of vitamin C or a placebo every day for four additional weeks. At the end of the eight-week period, the average blood vitamin C levels in the supplemented group were 41.7 micromoles per liter, but average levels among the depleted group were 9.7 micromoles per liter. Fatty acid utilization in the supplemented group was approximately four times greater than the vitamin C depleted group. Poor fatty acid oxidation during exercise was related to higher levels of fatigue.
These findings suggest that low vitamin C status is associated with poor fatty acid oxidation during exercise and may explain why some people are unsuccessful when trying to lose weight.

HOW COVID-19 IS DIFFERENT FROM THE FLU–Dr. V Interviews A Virologist
Iron and COVID-19
Down at the village cafe this morning a retired agricultural scientist told me about a paper in The Lancet that correlated serum iron levels with serious COVID-19 disease.
Does anyone have a link to a paper like that?
On a quick scan the one I found had a reverse correlation of serum iron to severe COVID19.
The Ag scientist has stopped eating red meat and gets his protein from fish during the pandemic based on the Lancet paper.
Whereas, I have been eating more beef and more steak during the pandemic tending toward ruminant-based low carb carnivore way of eating.
These data highlight the potential
hypoxic effect of anaemia in COVID-19
fatalities for sickle cell anaemia carriers
and for β-thalassaemia carriers. They
also indicate that haemochromatosis
type 1 might confer some protection.
Ferritin level increased with older age, increasing proportion of hypertensive study participants, and increasing proportion of mortality.
Not the Lancet but could it be this one?
and why did ya tag me here? LOL
about iron and covid? I sure have no experience or info on anything covid related for sure
