TUESDAY, Jan. 10 (HealthDay News) -- Studies have shown that vitamin D is critical for bone health and could have a protective benefit for the heart, but new research suggests that too much of it could actually be harmful.
"Clearly, vitamin D is important for your heart health, especially if you have low blood levels of vitamin D. It reduces cardiovascular inflammation and atherosclerosis, and may reduce mortality, but it appears that at some point it can be too much of a good thing," study leader Dr. Muhammad Amer, an assistant professor in the division of general internal medicine at the Johns Hopkins University School of Medicine, said in a Hopkins news release.
In conducting the study, published in the Jan. 15 issue of the American Journal of Cardiology, researchers examined five years of data from a national survey of more than 15,000 adults. They found that people with a normal levels of vitamin D had lower levels of a c-reactive protein (CRP), a marker for inflammation of the heart and blood vessels.
On the other hand, when vitamin D levels rose beyond the low end of normal, CRP also increased, resulting in a greater risk for heart problems.

What is the name of your K2 from Natto...can it be purchased online?
I see that again and again.
Life is a terminal, sexually transmitted disease.
WOW, a different side of you I didn't know.
Proud of you for being able to do that.
I order from iHerb.com, Nature’s Plus Source of Life Garden K2.
Too much of anything could hurt.
This is such crap.
You body can make 50,000 iu of vitamin d with about 20 minutes of large skin exposure around noonday sun. It is hardly deadly. It also keeps cholesterol down because cholesterol gets converted to vitamin d.
You will hardly take even 1/10 that amount in supplements a day.
This whole thing sounds funky, and it would likely fouled up by the journalist reporting it.
“Because there are a large number of disparate conditions that can increase CRP production, an elevated CRP level does not diagnose a specific disease.”
“The physiological role of CRP is to bind to the surface of dead or dying cells (and some types of bacteria) in order to activate the macrophage system that eliminates them. Thus, CRP participates in the clearance of necrotic and apoptotic cells.”
The “normal serum range” for vitamin D set by the Food and Nutrition Board is currently considered to be 30-90 ng/ml. Keep in mind, many, many experts consider this level inadequate for the prevention of most vitamin D deficiency related disorders.
This recommended blood level translates into a daily intake of 5000 IU for men and 6-10,000 IU of vitamin D per day for women. It is nearly impossible to maintain healthy levels of vitamin D through diet or sun exposure alone. Supplementation is almost always required.
Thanks.
10,000IU daily is far more than most people would consider taking.
Now I'll go bang my head for taking health advice from Coast to Coast. ;-)
actually the person the doctor is a heart doctor and has a lot of common sense.
Johns Hopkins and Johns Hopkins Medical are very different.
The medical school is considered very good. They also consider themselves very good. LOL
Yeah—I did a few things and had a few adventures before I settled down, got married, and produced 5 kids.
Now that I’m old and getting gray, I’ve got a heck of a lot of memories.........there’s not much I would change.
THanks
Thanks...I ‘goog’d’ it, and came up with:
Vitamin K2 (Menaquinone-4) is synthesized by animal tissues and is found in meat, eggs, and dairy products.
Always seems to come back to ‘moderation in all things’...
Found this all very interesting. My dr. had me start on D3 10/3 when my CRP was 4.2 just in range (needs to be under 5). I could tell something was going on after starting D3 cause I felt crappy. Had new bloodwork at the end of December now my CRP is totally out of range at 65!
Hmmm. Looks like a nice supplement but I’ve read not to take D and K at the same time of day as K inhibits D uptake.
