The role of vitamin D in preventing viral infections, including COVID-19, is gaining attention as more studies are released. In this video, Dr. Seheult of discusses a recent vitamin D review article published in the peer-reviewed journal Nutrients which has compelling implications for COVID-19 and overall vascular and endothelial health. (This video was recorded July 16, 2020).

  1. I found your videos at the beginning of Covid outbreak and the information provided has been helpful. Thank you for bringing to light all of latest research. I had been reading the studies on the CDC website, but you really breakdown the info. for easier comprehension.

  2. I wish I was smart enough to understand all of this! I have been getting a lot of sunlight, hope that is good enough for this summer.

  3. Hi Dr. Seheult, that's great news! Thank you so much for providing these videos! Do you think Dr.; that the use of activated charcoal can help in the treatment of this coronavirus? It has a nice long history of safe use and that Pliney used it for anthrax.

  4. Thank God! The timing of me finding your presentation have been a blessing. My family and I supplement our diet with Vit C on a daily basis due to seasonal allergies. However just a week ago, our son was suspected to have been exposed to the Cov-19 virus from a coworker. I had just listened to your presentation on some additional supplements that may aid the immune system. We started taking everything except Quercetin since it had to be ordered. His symptoms have been short-lived (less than a week of low fever, muscle aches, head pressure, fatigue), praise God and thank you, sir for your intelligence and willingness to educate.

  5. This could be a major contributor to the seasonal behavior of the common cold and the flu. With less sunlight in the winter, average vitamin D levels in the population falls, making people more susceptible to respiratory infections.

  6. Please note that 3 things are needed to make Vit D from the sun: 1. No sunscreen during sun time, 2. in the sun ~2 hours before or after solar noon (about 1p during DST), and 3. time your exposure to prevent burning. Try the phone app "Dminder".

  7. I got on the Vitamin D wagon a few years ago, during the winter months in northern US, my levels would readily drop to below 17-18 ng/mL, just before my annual November/December/January colds would arrive (I don't get the flu shot and I also don't catch the flu either since most people get the shot and I am thereby protected via herd immunity most years). Although Bolus dosing has not been shown to have a protective effect, for an obese darker skinned person like myself, getting on a weekly 50K IU dosing was necessary to make a difference. So I kept doing that for a month every winter, but did not actually ever develop a daily supplement habit otherwise. I haven't had a single respiratory infection, despite spending so much time on public transport and having a desk (unhealthy) job and being super unhealthy, not even a single cold, in 2 years. I have gone through some serious stressful travel and move situations that should have left my immune system pretty exposed, but nope, not a single respiratory infection since July 2018. However, I am also a germaphobe, do not have children, do not share my room with anyone, and I also have a diet rich in Vitamin C and I love fatty raw fish (tuna cans) and have milk and cereal multiple times a week. But I also have pre-existing conditions and happen to be immunocompromised.

  8. Thx, I have been supplementing w/ D3 for a couple months thx2u! You should mention that NO is a lethal, mutagenic toxin – for those undisciplined self-medicators out there! Blessings

  10. This is very good news, unfortunately, the bona fide of the journal has been questioned in the past. One reviewer (Wikipedia) explains "In August 2018, 10 senior editors (including the editor-in-chief) of the journal Nutrients resigned, alleging that MDPI forced the replacement of the editor-in-chief because of his high editorial standards and for resisting pressure to accept manuscripts of mediocre quality and importance."

  11. Genial,hace algún tiempo lei que uno de los factores mas importantes para vencer la pandemia de 1918 fue hacer tomar sol a los pacientes para aumentar su nivel de vitamina D..Sin duda la vitamina D será también imprescindible para vencer la actual pandemia.

  12. Very useful. Note that those Nitric Oxide pathways are enhanced by Red and Near Infrared light as well. Some of these cohort correlations are due to sun exposure by mechanisms that don't include Vitamin-D and UVB. "PhotoBioModulation" is mostly the study of what red and near-IR do for the metabolism. There's a lot!

  13. Look for NO & thrombosis studies direct causal link.. Nitric oxide is regulated by solar cycles.. Pandemics are directly associated with solar minimums.. Boom convid19..

  14. Th1 lymphocytes isolated from the lungs of patients with severe COVID-19 symptoms have an autocrine signaling pathway which should be activated, to turn the cells off their hyper-inflammatory program which produces pro-inflammatory IL-17 and instead make them produce the anti-inflammatory cytokine IL-10. However, this anti-inflammatory pathway is not working, due to lack of vitamin D. https://www.biorxiv.org/content/10.1101/2020.07.18.210161v1 , for a summary: http://aminotheory.com/cv19/icu/#2020-McGregor .

    This fits well with the observations from Newcastle upon Tyne that hospitalised COVID-19 patients have low vitamin D levels and that those in ICU had lower levels than those in the wards: https://www.medrxiv.org/content/10.1101/2020.06.21.20136903v2 and the recommendation that everyone needs 40 to 60ng/ml 25OHD for immune system health: https://doi.org/10.3390/nu12072097 – the article first mentioned in this video.

    Excessive adipocytes in obesity have ACE2 receptors and produce pro-inflammatory cytokines. There are apparently ectopic adipocytes in the alveolar interstitial tissue with both these properties: http://aminotheory.com/cv19/obesity/ .

    Vitamin D toxicity requires very high doses of D3 for a long time. See https://www.frontiersin.org/articles/10.3389/fendo.2018.00550/full , https://www.mayoclinicproceedings.org/article/S0025-6196%2815%2900244-X/pdf and https://vitamindwiki.com/Overview+Toxicity+of+vitamin+D .

    I have been trying to tell everyone about vitamin D, immunity and COVID-19 since late March: http://aminotheory.com/cv19/ . Dr John Campbell mentioned vitamin D for COVID-19 on 2020-01-28: https://www.youtube.com/watch?v=RECcmQQQOj8 though he only mentioned 0.025mg (1000IU) a day, which is about 1/4 of what normal weight people need, on average, to get close to 40ng/ml (100nmol/L).

  15. Vaccine science says they will inject you with the disease so you can get better by yourself , when nobody was sick in the first place . Flu shots are the same , you get some flu , in the injection , that you never would have ever caught in the first place .

  16. Thank you Dr Seheult for your lesson. Almost for 4 months, I have taken daily vitamin d3 iu 2000..but I have suffered of continuous consumption and colic pian …I have recovered to normal when I stopped talking vitamin d3.. I noticed also I lost 6 kilos of my weight during this period.

  17. And yet governments dnt advise vitamin d should be supplemented, especially for dark skinned people.
    I actually wrote a letter to my MPand requested that she bring this up in PMQs in Parliament. I received a reply, telling me that the NHS says that there is no scientist evidence showing that vitamin d has any effect on preventing respiratory infections.

  18. Currently I am taking Vitamin D and N.A.C. (N-Acetyl Cysteine) and L-Glutathione supplements. Do a little investigation and you will see the benefits of these supplements in the Covid-19 fight. Stay healthy
