Joseph Mercola dispenses a lot of good health advice, especially taking Vitamin D to prevent a serious case of Covid-19. From Mercola at lewrockwell.com:
In a June 22, 2020, Orthomolecular Medicine News Service press release,1 Damien Downing, president of the British Society for Ecological Medicine, outlines how we could resolve the COVID-19 pandemic in 30 days for about $2 per person, simply by taking affirmative action to raise vitamin D levels. The downside or risk of doing this is basically nil, while the potential gain could be avoiding another COVID-19 spike altogether.
“If we could arrange to give everyone vitamin D, and it failed to protect them, so what? The risk from not acting is much greater than the risk from acting,” Downing says, adding: “If you caught the COVID19 virus right now, having a good vitamin D status (from already having taken a supplement) would
- Reduce your risk of the disease becoming severe by 90%
- Reduce your risk of dying by 96%
This is not ‘proven’ or ‘evidence-based’ until we have done controlled trials comparing it to placebo … But the data, already strong, has been pouring in since the start of the pandemic.”
Although the required prospective randomized controlled trials using vitamin D have not yet been completed, they are indeed underway and results from many will be in before year’s end. You can visit the clinical trials registry to review the current state of these trials.2,3 As of June 2020, there were over 20 studies in progress on the use of vitamin D in COVID-19.
