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.

Ping
Dr. Muhammad ?
Oh I’m gonna listen to you fur sure
Life will kill ya.
Dr. Mercola had an article a couple months ago on the importance of supplementing with Vitamin K2 if you’re going to supplement with Vit D3. Some studies showed that K2 helps keep calcium from being leached from your bones by the D3 and being depositied, among other places, in your arteries. So, that might explain the heart health issues that this study was finding.
Johns Hopkins is considered among the best, if not the best, medical facility in the country. I don't care what his name is, the study should be viewed on its merits and findings.
I’m interested in what is considered “the low end of normal”.
Well, maybe I’m not, lol, I don’t “do blood”, and only partially remember numbers...is it 4 - 5000 IU’s?
Disclaimer: I take D supps to up my levels, and then back off a bit.
gator...life is one long trauma - no one gets out alive ;)
(’cept two that I’ve read of)
decimon, I appreciate your posts - much larnin here!
I wish... Actually as a person with heart problemsI have had a broad range of discussions with my cardiologist on subjects such as this. Being under the care of a cardiologist I felt qualified to make a joke about this...
smile a little
PS I am not bad with weapons either....
Thank you!
(that’s what I was talkin about with much larnin)
What are good food sources of K”2”? (see? I only knew of “K” - not surprised that I know only half as much as I think I know)
IMO, Hopkins is the best! I worked as an RN in their emergency room for a while, and I was thoroughly impressed!
Oh, the tales I could tell about some of the patients we saw there..................
About ten years ago my school system purchased a reading and math system based on the fact that it was produced by Johns Hopkins. The elementary teachers use it with glee because everything is scripted. Every Monday the students do the same thing, every Tuesday the students do the same thing, etc. There is even a scripted list of how to complement the students when they do well. The teachers have to do very little. Unfortunately I have classrooms full of functional illiterates and the math department can’t even get students to do simple math without calculators. This is all thanks to the Johns Hopkins program that we accepted on faith of the creator. Of course we will not get rid of the program because it’s not the program’s fault doncha know.
Everyone's different so it's not the amount ingested but the blood level. I've never had a blood test for vitamin D level and don't think one test would suffice. I just guess. Right now I'm taking 8,000IU daily but I'll back off of that before long.
FWIW, here's Dr. Cannell's formula: Purity Products. It contains K2.
I don’t understand why it would be important to take K2, magnesium or anything else with vitamin D as those things don’t come with sunlight. Maybe the fact of ingesting the vitamin D changes the equation somehow.
The only source of K2 that he had listed was Natto. I take a K2 supplement that is derived from organic Natto because I’m a skeptic on the safety of GM soy.
His explanation was that if you get your D solely from sunlight you didn’t need to worry about it, because that form of D is actually water soluble. But the D3 supplementation is only fat soluble and had something to do with the difference in the two types. Even though sunlight does produce D3 in the body the two (sunlight vs. supplement) aren’t identical.
What KIND OF Vitamin D!!!!!????? Sheesh, we have really crappy “journalists.” And, maybe researchers, too.
Followup....Vitamin D3 is the D vitamin to supplement... this article doesn’t even mention it.
Thanks! That is the correct form of K. Dr. Mercola claims we actually need about 200 mcg per day. Maybe I missed it, but I didn’t see the source of the K2, and I’m always interested in the source of each vitamin. I’m a skeptic on the safety of GM food and since soy (Natto) is a source of K2 I’d be afraid that they’re using conventional soy, which is probably GM. At this point foods aren’t allowed to be called organic if they’re GM.
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!
