*This is a re-post of information for those who may not have seen it:* A new study (actually a review of many studies) concludes that people with a Vitamin D3 blood level of greater than 50 ng/ML [25(OH)D3] have almost a ZERO risk of dying from COVID. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8541492/ *How to Achieve Optimal D3 Levels* Historically, the level of Vitamin D3 recommended by the experts ranges from 400 IU to 2,000 IU a day, which falls far short of getting you to the 50 ng/ml level you need. This video explains why the "experts" are wrong (too low) and how to calibrate it for yourself. This doctor recommends 10,000 IUs a day for a healthy person. (Higher amounts may be needed if you have a compromised immune system, insulin resistance or genetic mutations.) It's a must watch. https://www.youtube.com/watch?v=NFxQJmvgXOQ This doctor says he targets 60 - 80 ng/ML blood level and once tested and determined a patient is low, prescribes 10,000 IU a day until the desired level is achieved, which will likely take weeks. Once achieved, the doctor adjusts the level to 4K-6K daily and retests to ensure optimal level is maintained. Watch here: https://youtu.be/6E9xfwyX6mQ?t=608 Unsure what level of supplements to take? The safest way to determine if you need to increase your Vitamin D3 intake is to get a simple blood test from your doctor (or you can order a home test online). **IMPORTANT: You need to add Vitamin K2 when taking high dose Vitamin D3 -- it prevents calcification in your arteries and soft tissue.** *Note: Vitamin D3 is fat soluable so it's best to take it with a meal to ensure absorption*
