Vitamin D stops bone loss

It's the oldest trick in the book. If you want to "prove" a vitamin doesn't work, you use a low dose -- and when an ineffective dose proves to be ineffective, you can write the whole thing off.

Last week, I told you about a study that did just that. It dismissed vitamin D supplements by using paltry levels of 400 IUs per day, or less than what even mainstream health officials recommend.

Today, I want to show you the other side of the coin. I want to show you what happens when get closer to what you need -- because new research on the vitamin D benefits confirms that vitamin D supplements can stop the loss of bone mineral density that comes with age.

That's the bone loss that could lead to a crippling break or fracture, or even disease such as osteoporosis.

And vitamin D benefits can stop it cold -- but only if you get enough.

In this study, women given 1,000 IUs of vitamin D3 per day had no loss in bone mineral density measured at the hip after a year. None at all.

Women given 400 IUs per day -- the same amount used in that other study -- suffered a loss of 0.6 percent, not coincidentally the same bone loss suffered by women given a placebo.

In other words, 1,000 IUs a day can work wonders... while 400 IUs per day is like taking nothing at all.

And that, my friend, is why it's just not enough to take any old supplement. You need to make sure you get the right amount, too. While the 1,000 IUs in the new study is a good start, I recommend an absolute minimum of twice that, or 2,000 IUs per day.

And you might need even more.

Here in my clinic, I've found that some people need as much as 5,000 IUs of D3 per day to reach optimal blood levels.

And believe me you want optimal levels -- because along with protecting your bone, vitamin D benefits can help your heart and brain, boost your immune system and even fight cancer.

Your own needs will depend on your health, where you live, how much sun exposure you get and more. The best way to sort it all out is to get tested by a holistic physician who can help determine exactly how much you need and the best way to get it.
