More Vitamin D Information

Andy, who takes daily nutritional supplements, wrote to ask about if his general fatigue could be related to an excessive amount of Vitamin D. He said he takes 800 IU a day. He was worried about a toxic dose. I wrote Andy back and said it is very un-likely that an excess of Vitamin D is causing his fatigue or lack or energy. Much more likely that he is taking considerably less Vitamin D than he needs or that he is consuming low quality, food grade supplements and therefore cannot determine what amount he is really taking. Andy also asked about the benefits of Vitamin D as he had forgotten why he added them to his daily nutritionals.

First of all, the FDA's current recommendation of 600 IU a day of Vitamin D is thought to be too low. Many researchers are now suggesting that 2,000 IU a day may be the minimum amount. I currently take 5,200 IU of Vitamin D each day. Vitamin D is necessary for normal bone mineralization and growth including teeth. Vitamin D assists in the absorption and utilization in the body of phosphorus and calcium. Vitamin K is also important too for bones as Vitamin K helps direct calcium to the bones and not the in soft tissues such as organs or muscles.

I don't know if anyone has figured out what the minimum level for a toxic dose of Vitamin D is, although the Mayo Clinic has published an article stating "taking 50,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause symptoms such as poor appetite, nausea and vomiting. Weakness, frequent urination and kidney problems also may occur."

Vitamin D Deficiency Symptoms

I was happy to see this well written article on Vitamin D Deficiency and the symptoms explained from Natural News. I take about 5,000 IU daily in supplement form as I think Vitamin D is very important for the immune system and bone strength which helps maintains good joint health. A good quality Vitamin D supplement is actually pretty cheap and easy to take (small tablet). I'd like to see more senior citizens being placed on Vitamin D by their primary care managers. I'll just bet it would help reduce bone injuries related to falls and other trauma, as well as good for heart disease, blood pressure and joint pain.

I'm 55 years old with a usual BP in the range of 118/74.  I am told by my Doctor that I am in the bottom 1/6th of the population for risk of heart disease.  I haven't been sick in 9 years.  So even a skeptic would have to believe that there is a benefit to consuming high quality supplements which would include Vitamin D.        

The importance of vitamin D is well known. As far back as the 1930s, doctors first recognized the link between a vitamin D deficiency and the skeletal disease called rickets. Rickets causes a softening of the bones and teeth. Even if someone's diet has adequate levels of calcium, without enough vitamin D to properly control calcium and phosphate levels in the blood stream, demineralization of the bones can take place. The symptoms of rickets include bowed legs, bone pain, dental problems, a widening of the wrists, frequent bone fractures and skull deformities.

Because rickets is seldom seen in first-world countries, it's easy to think that vitamin D deficiencies are a thing of the past. However, new research has recently shed light on other, more subtle, symptoms of a vitamin D deficiency. Many illnesses which, at first glance, seem totally unrelated to something as physically obvious as rickets actually may have their roots in a lack of vitamin D.

Just what is vitamin D?

The term vitamin D, according to the Mayo Clinic's Drugs and Supplements site (1), actually refers to several different forms of the vitamin, including D2, which comes from our diet, and D3, which is manufactured by our skin when exposed to sunlight. Vitamin D's main purpose in the body is to regulate blood levels of calcium and phosphorous.

The sunshine vitamin?

It's actually hard to get enough vitamin D from a normal diet. It's found at the highest concentration in fatty fish such as tuna, mackerel and salmon. Some mushrooms are also high in D, and their level of the vitamin actually increases when exposed to ultraviolet light.

While our skin does manufacture some of the vitamin D that we need daily, sun exposure alone is usually not enough. Factors such as the time of year, the angle of the sun, cloud cover, pollution levels and even the use of sunscreen can greatly limit the amount of D made by our skin.

Vitamin D deficiency symptoms explained: the top 9 warning signs

Some people who have a vitamin D deficiency have no immediate symptoms. Those who do have symptoms may experience restless sleep, muscle cramps, general fatigue, joint pain, muscle pain or weakness, inability to concentrate, headaches, constipation or diarrhea, and bladder problems. Here are nine other serious medical conditions that have been linked to a vitamin D deficiency.

1.  Asthma - Vitamin D supplementation of 1,200 IU daily has been shown to lessen asthma attacks and reduce their severity.

2.  Depression - Vitamin D deficiencies have been linked to depression and other psychiatric illnesses. Even a woman getting enough D during pregnancy has been shown to lessen the chances that her unborn child will develop mental illness later in life.

3.  Heart disease - An article published in Molecular Nutrition & Food Research (2) reports that cardiovascular disease is much more common in people deficient in vitamin D. Some children, according to the article, with severe heart failure have also responded well to vitamin D treatment.

4.  High blood pressure - High blood pressure has been associated with deficiencies in calcium, magnesium, potassium and vitamin D.

5.  Rheumatoid Arthritis - RA is a devastating disease that causes systemic inflammation, severe pain and joint damage. Studies have shown that vitamin D can ease the pain and stiffness associated with RA.

6.  Multiple sclerosis - Studies have shown that geography matters when it comes to the odds of getting MS. The farther from the equator you live -- and the less sun exposure you get -- the more likely you are to develop the disease. This suggests a strong link between MS and vitamin D.

7.  Cancer - Several different kinds of cancer have been linked to D deficiencies, including breast cancer, prostate cancer and colon cancer. The causal link is so strong, in fact, that the Mayo Clinic  lists separate recommended dosing levels of the vitamin for both cancer prevention and prostate cancer treatment.

8.  Periodontal disease - This inflammation of the gums can cause pain, bleeding and tooth loss. Vitamin D helps in the formation of defensins and cathelicidins which, in turn, can lower the number of harmful bacteria in the mouth.

9.  Diabetes - An article from World's Healthiest Foods (4) lists poor blood-sugar control as a symptom of vitamin D deficiency. This, in turn, can increase the risk of developing diabetes.

Good Osteoporosis Article

A very good article on Osteoporosis from Real Age.  10 Facts About Osteoporosis and Bone Health Learn about common causes and risk factors for osteoporosis.

Throughout your life, you constantly lose old bone and form new bone. As a teenager and young adult, your body made more bone than you lost. But with age, bone production drops off and bone loss increases, putting you at risk for osteoporosis (porous bone, which fractures easily). According to the National Osteoporosis Foundation (NOF), roughly 10 million Americans have osteoporosis and 34 million have osteopenia (low bone mass). But osteoporosis and related fractures don't have to be inevitable. Here are 10 things you need to know to lower your risk.

A broken bone might mean you already have osteoporosis. A simple fall that results in a fracture is the most telling sign that you may have osteoporosis, says Connie Weaver, PhD, chairman of the department of nutrition science at Purdue University and a calcium researcher. "Many times, people just assume the fracture is due to the trauma and don't investigate if they need to be treated for osteoporosis," Weaver says. But it's possible that the fractured bone was already in a weakened condition due to osteoporosis before the fall. People who break a bone and have other risk factors for osteoporosis -- such as a small build or a family history of fracture and low body weight -- should be especially vigilant, she says.

Having diabetes can raise your risk for osteoporosis. People who have type 1 diabetes or type 2 diabetes are prone to weaker bones. "The quality of the bone they make isn't good," says Diane Schneider, MD, a geriatrician and the author of The Complete Book of Bone Health. "In people with type 1 diabetes, there is more bone breakdown, and in people with type 2 diabetes, the bones are more fragile." Medications for type 2 diabetes can also cause bones to be weaker. Even extra body weight doesn't help. "We're finding a growing connection between bone and fat," Schneider says. "Being overweight is not as protective as we once thought it was."

Being thin increases your chances for osteoporosis. Having a small frame and a slight build means you have bones that are less dense, making them more vulnerable to osteoporosis and fracture. Some studies show you may be especially prone to developing osteoporosis if you weigh 127 pounds or less, Schneider says. Since there isn't much you can do about the way you're built, women who are small-boned need to take charge of osteoporosis risk factors that they can control. "You have to pay special attention to what I call the ABCDs of bone health," Schneider says. "Activity, balance -- because you need core strength to prevent falls regardless of bone density -- calcium, and vitamin D."

Not getting enough calcium puts your bones at risk. Calcium is a mineral essential to bone strength, but a recent study showed that many Americans may not be getting enough of it in their diets. Before you reach for a bottle of supplements, new research suggests taking calcium supplements may raise your risk of heart attack and kidney stones. The fact remains that calcium is a necessary part of our diets. According to the Institute of Medicine, women need 1,000 mg of calcium each day up to age 50, and 1,200 mg of calcium a day after age 50. Schneider recommends getting the bulk of your calcium from food -- milk, yogurt, broccoli, turnip greens, and calcium-fortified foods -- and taking less than the recommended dose of calcium supplements.

A lack of vitamin D raises your risk for osteoporosis. Vitamin D is essential for bone health because it helps your body absorb calcium. Spending just 20 minutes a day in the sunshine -- without sunscreen -- during the summer months provides enough vitamin D to last you through the year, says Dana Simpler, MD, a physician in private practice in Baltimore, MD. "People with dark complexions may need up to an hour," she says. You can also get vitamin D from supplements and foods such as dark leafy greens, and vitamin-D fortified orange juice and soy milk. According to the Institute of Medicine, most people need 600 IUs of vitamin D a day. People aged 71 and over require 800 IUs of vitamin D daily, possibly more, depending on their health.

Some medications can hurt your bones. Certain medications -- among them antidepressants, corticosteroids and proton pump inhibitors -- can put your bones at greater risk for osteoporosis. Anti-seizure medications, certain cancer treatments, and diabetes drugs may also cause bone loss. In most cases, the risk of osteoporosis goes up the longer you take these meds and the higher the dose. Before going on any medication, ask your doctor about the impact on your bones. If you must take one of these drugs, work with your doctor to take the lowest dose possible, and discuss ways to lower your risk of osteoporosis.

After menopause, your risk for osteoporosis goes up. For women, menopause causes a steep drop in estrogen, a hormone essential for strong bones. The earlier you go into menopause, the higher your risk of osteoporosis. A recent Swedish study found that women who entered menopause before the age of 47 were nearly twice as likely to have osteoporosis later in life as those who entered menopause when they were older. "Women lose the most bone in the first three to five years of menopause," Weaver says. "They can lose as much bone as they gain during puberty." Menopause, says Weaver, is an important period to make lifestyle choices that protect against bone loss, namely with exercise and diet.

A bone density test can detect bone loss. Bone density is commonly measured with dual-energy x-ray absorptiometry (DXA), also known as a bone density test. This simple, painless test gauges bone strength by comparing your bone mass to those of young adults of the same gender at peak bone mass, using a T-score. A T-score of -2.5 or lower, means you have osteoporosis. A score between -1.0 and -2.5 means you have osteopenia, low bone mass. A T-score of -1.0 or higher means your bones are normal. "Women usually don't need a DXA scan until they're 65 and men until age 70," says Schneider. Talk to your doctor about when to get screened and about follow-up tests. The answer will depend on your age, osteoporosis risk factors, and previous bone density test results.

Being physically active protects you against osteoporosis. Weight-bearing exercises -- the kind that force your body to work against gravity, such as walking, running, dancing, and tennis -- are the best for keeping bones healthy. The key, Schneider says, is to simply be active. "It doesn't have to be exercise in the gym," she says. "You simply want to spend more time on your feet and move. You want to spend less time sitting."

Not everyone with osteoporosis needs medication. In recent years, some drugs used to treat osteoporosis have come under fire for potentially increasing the risk for breakage of the femur bone, esophageal cancer, and the death of bone tissue in the jaw. In reality, only women at high risk for a fracture need treatment, says Ruth Freeman, MD, a professor of obstetrics-gynecology at Montefiore Medical Center in the Bronx. "I always recommend lifestyle changes first," Freeman says. Women who have osteoporosis and other risk factors such as rheumatoid arthritis, low body weight, and a family history of fractures for instance, may want to take osteoporosis drugs. But women who have no other risk factors might consider opting out. Talk to your doctor about your best option.

The Truth? About Milk - I drink It!

Milk has been long thought of as a necessary component for healthy bones. Calcium, found in milk, is not only associated with bone strength but necessary for cardio-vascular and heart function as well. I have drank milk, usually 2% or Whole, both pasteurized and organic (and I highly recommend organic) for over 40 years now. I consider Milk, again especially organic milk, an excellent addition to the diet. I mix a low glycemic meal replacement powder and a fiber powder with my milk and have that for breakfast around 6:00 am. I usually don’t get hungry until well past noon.

The 12% or so of people who are lactose intolerant should consider Soy milk as a replacement. Some people who are lactose intolerant may want to try a high quality Pro-biotic and Digestive Enzyme which can often make the different in nutrient breakdown and absorption. I routinely use a very high quality pro-biotic and digestive enzyme and consider it a essential part of my nutritional program and overall health.

The Truth About Milk

By David Zinczenko, Dec, 2010

Milk: Healthy and nutritious drink, or fattening, contaminant-filled menace?

You might expect an organization called the Dairy Education Board to promote milk as a good thing. But instead, this advocacy group claims that “Milk is a deadly poison.” Oops. And as Americans have grown more wary of saturated fat, and more concerned about hormones and other substances fed to—and injected into—dairy cows, milk consumption has fallen dramatically. In the post-war days of 1945, the average American was consuming 45 gallons of milk a year. By 2001, per capita consumption was down to just 23 gallons.

But here’s the thing: Plenty of new research says that we should be drinking more milk, not less. In fact, swapping soda, juice, sweetened iced teas, and other beverages for milk might be one major reason why Americans are gaining weight at such a rapid pace. Milk not only helps boost protein intake and cut down on sugar, but consuming calcium through dairy foods such as milk may actually reduce the fat absorption from other foods. Who wouldn’t want that? Hungry for more hard-hitting nutrition facts and findings every day? Read the book series – “Eat This, Not That!” and “Cook This, Not That!” series.

Here are four milk myths you might have heard, and why you should consider answering the cowbell more often.

Claim #1: “Milk is a fat-burning food.”

The Truth: Maybe. In a 6-month study, University of Tennessee researchers found that overweight people who downed three servings a day of calcium-rich dairy lost more belly fat than those who followed a similar diet minus two or more of the dairy servings. In addition, the researchers discovered that calcium supplements didn’t work as well as milk. Why? They believe that while calcium may increase the rate at which your body burns fat, other active compounds in dairy (such as milk proteins) provide an additional fat-burning effect.

Claim #2: “Drinking milk builds muscle.”

The Truth: Absolutely. In fact, milk is one of the best muscle foods on the planet. Milk is full of high-quality protein: about 80 percent casein and 20 percent whey. Whey is known as a “fast protein” because it’s quickly broken down into amino acids and absorbed into the bloodstream—perfect for post-workout consumption. Casein, on the other hand, is digested more slowly—ideal for providing your body with a steady supply of smaller amounts of protein for a longer period of time, such as between meals or while you sleep.

Claim #3: “Cows are given antibiotics. Doesn’t that make their milk unhealthy?”

The Truth: No one really knows. Some scientists argue that milk from cows given antibiotics leads to antibiotic resistance in humans, making these types of drugs less effective when you take them for an infection. But this has never been proven. It is true that hormones and antibiotics have never been part of a cow’s natural diet, and they have been shown to have adverse effects on the animals. Canadian researchers, for example, discovered that cows given hormones are more likely to contract an udder infection called mastitis. If you’re uneasy, you can purchase antibiotic-free (and typically hormone-free, as well) milk from producers like Horizon and Organic Valley at most major supermarkets. The cows will certainly thank you.

Claim #4: “Fat-free milk is much healthier than whole.”

The Truth: Nope. While you’ve probably always been told to drink reduced-fat milk, the majority of scientific studies show that drinking whole milk actually improves cholesterol levels—just not as much as drinking fat-free does. One recent exception: Danish researchers found that men who consumed a diet rich in whole milk experienced a slight increase in LDL cholesterol (six points). However, it’s worth noting that these men drank six 8-ounce glasses a day, an unusually high amount. Even so, their triglycerides—another marker of heart-disease risk—decreased by 22 percent. The bottom line: Drinking two to three glasses of milk a day, whether it’s fat-free, 2%, or whole, lowers the likelihood of both heart attack and stroke—a finding confirmed by British scientists.
