Reader Hanyun used the website's "Contact Me" to inquire: I followed a doctor's face and he just shared the help of vitamin D for muscle repair. Because you have also shared many myths about vitamin D, so please ask what are your opinions on the functions mentioned in this article?

The article said by this reader was published by Dr. Zhang Fengren on 2019-12-20 on a website called RACE ON (Running Medical Column). The title is [Running Medical Column] Lost Gold – Vitamin D. RACE ON is the website of a health care product company. Its products include "Hydrogenic Electrolytic Liquid", "Liquid Shield Vitamin D+E Drops", etc.

What are the inexplicable water products? 》

《Low deuterium water can cure cancer? 》

"Silky water, true and false"

Regarding "Liquid Shield Vitamin D+E Drops", this is of course the real protagonist of this article by Dr. Zhang Fengren, and isn't the illustration in the article a little boy holding a bottle of "Liquid Shield Vitamin D+E Drops"? Just play with children to see this kind of trick.

This article is very long, so I won’t reveal its scars one by one. I just opened the most important piece that the author believes. He said:

Muscle Recovery: I have to say this is the reason I wrote this article. The importance accounts for more than 50% and is very simple and clear. In the Randomized control trial, they conducted research on elderly people with muscle loss and found that when the elderly have sufficient vitamin D, there is a clear difference between the resistance training mechanism and the control group, that is, elderly people with sufficient vitamin D are stronger. The 2018 document recommended to replenish it to 4000 IU per day, and the concentration should be as high as 75 nmol/L or above. Based on the current domestic nutrition recommendation, daily intake of 200-400 IU is recommended, which personally thinks is far away. We don’t just avoid fractures. Sportsmen who pursue performance must also establish good muscle quality, just our exoskeleton!

The Randomized control trial mentioned in this article looks very professional and authoritative. But the question is, what exactly is Randomized control trial? Where is the reference? "2018 documentary suggestions to supplement to 4000IU…"? What kind of literature is this?

There are 5 References at the bottom of the article {twenty three} {twenty four}

No matter what, there is a conclusion about how vitamin D supplements can strengthen muscles. But can not male hormones strengthen muscles? What's more, it's still a strife research result. But, please, do you dare to take male hormones? Why are athletes banned from taking male hormones?

I have said many times that vitamin D and male hormones are both "sterol hormones", and all "sterol hormones" can be used to carry and overturn. And because of this, both male hormones and female hormones require a doctor's prescription. Only Vitamin D can be bought anywhere, and anyone can take it freely. Please watch "Vitamin D is a hormone and vitamin D, but it is not supplemented."

Yes, vitamin D supplements may strengthen muscle, but what is the price? Please watch "Calcium and Vitamin D supplements increase death risk".
