Ingredients That Improve Bone-Joint Health

Bone and joint health is one of the most common areas of health that people deal with on a daily basis. The numbers back it up:

• The CDC reports that 30 percent of Americans experience some type of joint pain each month. That number increases depending on who’s doing the reporting.
• One in five people suffer from chronic pain and the same amount, according to the CDC, have been diagnosed with arthritis by their doctor.
• By 2030, an estimated 67 million Americans ages 18 years or older are projected to have doctor-diagnosed arthritis.

These statistics have led to a surge in the bone & joint health industry, as experts predict that the sale of bone and joint supplements will exceed $9 billion globally by 2017. This booming market has led researchers to identify the top ingredients for bone and joint health – not from a marketing perspective, but to let the public know what actually works to help improve your bone and joint health.

Outside of calcium and vitamin D – long proven to benefit your bones – there are a multitude of ingredients and products claiming to improve your bone and joint health. So what works? Recently, the experts weighed in, and here’s what they found:

Vitamin K: The correlation of vitamin K to cardiovascular and bone health directly focuses on supporting proper calcium utilization. Known as the calcium paradox, it simply means getting calcium in the right place: into the structure of the bone structures instead of the artery walls). One particular form of vitamin K – vitamin K2 – promotes the synthesis of proteins involved with calcium utilization, thereby supporting bone retention and arterial health.

Magnesium: According to researchers, up to 80 percent of people do not get enough magnesium. This can have a lasting effect on bone & joint health, as magnesium is a critical component of the mineralized part of bone and supports the normal metabolism of potassium and calcium in adults. Magnesium – the fourth most abundant mineral in the body – also supports more than 300 enzyme systems, including nerve function, adaptation to stress, metabolism and more.

Glucosamine: Naturally produced by the body and a key component of cartilage, glucosamine is concentrated in joint cartilage, and has been scientifically proven to support healthy joint function and promote the normal production of synovial fluid, which lubricates your joints and regenerates cartilage.

Omega 3s: We’ve written about the benefits omega 3 fatty acids have on inflammation before, and the bone and joint health industry is catching up. The American Heart Association has recommended omega-3 fatty acids to reduce the risk of inflammation not just to improve your heart health, but your overall health, as well.

One ingredient the experts failed to mention that has been shown to help the body’s inflammatory response is Pycnogenol. Research has shown that Pycnogenol – a water-soluble, flavonoid complex extracted from the bark of the French Maritime Pine tree – may inhibit the activation of NF-kappa B and AP-1, both of which are proinflammatory mediators. In addition, studies have shown the ability of Pycnogenol to cross-link collagen fibers and strengthen connective tissue proteins.

Study: Fish-eaters stay sharper with age
Researchers say one meal a week slows decline by 10 percent

CHICAGO, Illinois (AP) -- Eating fish at least once a week is good for the brain, slowing age-related mental decline by the equivalent of three to four years, a study suggests.

The research adds to the growing evidence that a fish-rich diet helps keep the mind sharp. Previous studies found that people who ate fish lowered their risk of Alzheimer's disease and stroke. Fish such as salmon and tuna that are rich in omega-3 fatty acids also have been shown to prevent heart disease.

For the new study, researchers measured how well 3,718 people did on simple tests, such as recalling details of a story. The participants, all Chicago residents 65 and older, took the tests three times over six years. They also filled out a questionnaire about what they ate that included 139 foods.

"We found that people who ate one fish meal a week had a 10 percent slower annual decline in thinking," said co-author Martha Clare Morris, an epidemiologist at Rush University Medical Center. "Those who ate two fish meals a week showed a 13 percent slower annual decline."

The study was posted Monday on the Web site of the Archives of Neurology and will appear in the journal's December issue. It was published early online because of its general interest.

The researchers looked for, but failed to find, a link between omega-3 fatty acids and protection from brain decline. Previous studies found such a link.

Morris said it is possible that something else about eating fish worked to keep people's minds sharp. Or the food questionnaire might have been too broad to allow researchers to estimate omega-3 intakes accurately, said Dr. Pascale Barberger-Gateau, who does similar research at the University of Bordeaux in France but was not involved in the current study.

In the questionnaire, "only four seafood items were included, which did not allow this distinction," Barberger-Gateau said in an e-mail.

The questionnaire included four broad seafood categories: tuna fish sandwich; fish sticks/fish cakes/fish sandwich; fresh fish as a main dish; and shrimp/lobster/crab.

Testing participants' blood for omega-3 fatty acids would have given a more definitive measure, said Dr. William E. Connor of the Clinical Nutrition Department of Medicine at Oregon Health & Science University. He was not involved in the study.
