Vitamin D destroyed my deep sleep

I want to tell the whole story of how I figured this out, but I will just cut to the data.  Here is a graph of the amount of deep sleep.  Its almost a year of data (Jul 30, 2011-Jul 8 2012).



You'll notice that the first night I had 54 minutes of deep sleep which is the highest amount of deep sleep in the time period.  There was one other 50+ night  and 9 40+ nights of deep sleep and they were all before Aug 27 2011 (the red line).

For perspective, according to Zeo, the average amount of deep sleep for males aged 30-39 is 59 minutes.

After the red line, my deep sleep cratered. It hovered in the 10-20 minute range. Except for one period from the middle of January to February, it stayed that way for almost a year.

I have done all kinds of tests in the year trying to improve my deep sleep and haven't experienced much success. So what was the red line?  It was when I switched from 4000IU to 5000IU Vitamin D every day.

There has been research suggesting that a Vitamin D deficiency can cause sleep issues. In March of 2011 (before I switched to 5000IU) I was tested at 44ng/mL...so no reason to think I was deficient at any point in the sleep tracking.

In the alternative health blog world, there is a lot of discussion that Vitamin D timing can affect sleep quality.  In most of 2011, I took it at night.  Most of 2012, I took it in the morning.  You can see from the graph it didn't make much of a difference.

I haven't seen anything before that suggests too much Vitamin D (at any time) can cause sleep issues. Also, to be clear, I had my Vitamin D level tested in December (after 4 months of 5000IU).  It was 89.5 ng/mL - well under the level considered excessive (100 ng/mL).

But I still think too much Vitamin D is what caused the decrease in deep sleep.

I made this determination on July 8 (the other red line).  I stopped taking any Vitamin D and put on suntan lotion when I went outside.  The halflife of Vitamin D in the body is a month.  So what happened a month after I stopped?



My deep sleep went way up.  That's what happened.  I have had multiple nights of 50+ minutes of deep sleep and my first ever 60+ minutes of deep sleep. I have gotten more deep sleep  in the past 11 nights than the last 33 nights while I was taking Vitamin D. Pretty awesome.

I went and had my blood tested the first time my sleep broke 50 minutes.  It was 55.5 ng/mL.

I'd love to hear any comments/questions. I think a lot of people in the paleo/alternative health world are taking a lot of Vitamin D so I think it would be great

EDIT:  I updated the post to go into a little more detail about what time of day I took Vitamin D.

February Lab Results

Well.  What can I say?  It is a good month for the cholesterol.  Lets just get to it.

Original                                       January                                 February
HDL - 29                                    HDL - 35                              HDL - 38
Triglycerides - 276                      Triglycerides - 139                 Triglycerides - 103
 LDL - 93                                    LDL - 101                            LDL - 88
VLDL - Not tested before           VLDL - 28                            VLDL - 21

Records for everything.  This is definitely nice after such a lackluster month After almost (a short) month of Niacin I had hoped my HDL would be higher but still the highest level on record (31% increase in HDL).  Particularly impressed with the drop in triglycerides (83% decrease).  5% decrease in LDL.

Plan is to continue Niacin and low carbing it (Only 3 cheat days in February).  I will probably delay exercising until April.

January Lab results

The month was pretty solid with less than 5 cheat days.  Pretty much a constant stream of eggs, beef, fish, veggies and berries.  I was rewarded with an average of 85 morning blood sugar.  I was looking forward to my lab results coming back with some solid numbers.  I was a bit dissapointed


Original                                       December                             January
HDL - 29                                    HDL - 37                              HDL - 35
Triglycerides - 276                      Triglycerides - 148                 Triglycerides - 139
LDL - 93                                    LDL - 118                              LDL - 101
VLDL - Not tested before           VLDL - 30                            VLDL - 28

Slight dips in everything - INCLUDING HDL.  Very frustrating.  It appears it takes more than a steady stream of saturated fat to increase HDL for me.  If it had even been a slight uptick I probably would have stuck with what I was doing.  Since it didn't I am upping the ante by adding 100mg of Niacin to my daily routine.  I'll let you know what comes of it

I am also adding a bit more carbs to my meals.  That will mainly mean adding some rice to my near daily mongolian grill and berries to my dinner.  My morning blood sugar was rising even thought my diet wasn't really changing.  I think this is because of increased insulin resistance due to eating VLC.  Gonna add some back.  I can already tell you that morning blood sugar has dropped back into 80's after a day.

Blood Pressure improving slowly but surely

Inspired by this Hacker's Diet tactic of taking a running 10 day average of weight, I did the same thing with my blood pressure readings.  I think this one speaks for itself.

I think a couple of interesting notes come from this

• Other than Vitamin C, there was no magic bullet that had an obvious immediate impact.  There is no dramatic drop at any point, but I think the trend is pretty clear.  I can only conclude that reduction in carbs, increase in potassium, addtion of Vitamin C, and regular emWaving has had a cumulative effect.
• I think this 10 day average technique is good for things that have a lot of noise.  There are a lot of variables that make tracking blood pressure difficult. The smoothing that a 10 day average gives makes the trend clearer than a simple graph of every data point
• From a motivational perspective, this is invaluable.  I can now stop freaking out over a single bad morning measurement and have faith that I am on the right track in one fell swoop.
