Vitamin D is one of the most important, if not the most important Vitamin for our health and immune system. Vitamin D deficiency can disrupt a whole host of systems in your body. Causing your body to age faster, get more colds, and according to Why We Sleep author Matthew Walker on the Joe Rogan podcast, even disrupting sleep. How do you know if you are getting enough?
There is only on way to know your current Vitamin D levels, and you need to do a blood test. Without a blood test there is no real way to tell. There are no other signs or symptoms you can look at because overall your body will be running at sub-optimal levels across all your key systems.
The good news is that you can supplement Vitamin D and anyone that takes 1000IU of Vitamin D should see their blood levels increase by 5ng/ml. Even science researchers like Dr Rhonda Patrick’s supplement list features Vitamin D quite heavily. She takes as much as 5000IU a day now after COVID19 related research has shown that it improves respiratory immunity.
Now that you know how important it is, the first step is to go and get the blood test. Then, start a supplementation regime that elevates your levels to what we truly need, which is between 40 and 60 ng/ml. Continue testing and adjust as you go along. Your doctor will advise you on how long you should wait between test. Keeping it at those levels will need consistent tests and changes to your lifestyle.
