Nutrients for Bone and Joint Health Interview

This interview was given to Whole Foods Magazine, excerpts were published in the February 2011 issue:

Despite evidence in recent medical journals, including several review studies calling for a far higher RDA and UL (upper limit) that would be five times the previous levels, the IOM held true to its conservative bent and raised the RDA and the UL; but only by 50% by only 100%, respectively . Observers are somewhat disappointed, but not really surprised. The most controversial part of the IOM committee’s report is that the only proven role for vitamin D is in bone and calcium metabolism, combined with its finding that most Americans already get enough for those benefits. That should come as news to researchers from Mayo Clinic operating under an NIH grant who recently reported that “Vitamin D insufficiency is common globally and in the United States. Approximately 25-50% of patients seen in routine clinical practice have vitamin D levels below the optimal range…” It also should be news to European regulators that recognize vitamin D’s beneficial effects on muscles, immunity, inflammation, cellular health, and reproduction. We recognize the new increased recommendations for vitamin D and the new higher safety recommendation, but believe that these numbers are insufficient to support vitamin D’s roles that go beyond calcium and bone health.

The need for joint and bone health nutrients in general increases with age. Aging also tends to reduce absorption of nutrients, forcing us to take higher amounts and better forms in order to assure adequate nutrition. The tendency of many seniors to cut back on meals, for reasons such as loss of taste or smell or interest in cooking, may also increase the need for supplementation of essential nutrients. The major joint and bone problems increase with age, and studies have shown the ability of relevant nutrients to maintain healthy bone and joint structures during these vulnerable times of life. Older customers that are more likely to take calcium supplements also tend to have diminished stomach acid available for digesting calcium from food and non-chelated (predigested) forms, so tend to do better with the predigested forms. These include calcium as citrate, malate, ascorbate, or bonded to specific amino acids; all are weak acidic sources that form a stable bond with the alkaline calcium and the resulting compound simulates the calcium complexes formed naturally during proper digestion.

While calcium and vitamin D are known for their role in bone and calcium metabolism, there are other nutrients necessary for bone health. These include silica, boron, magnesium, vitamins C and K, etc. protein. Comprehensive bone formulas include over a dozen nutrients, which are also available singly.

Children need to get sunshine, exercise, and a variety of calcium from food sources to ensure the body’s needs for bone health. If the child does not eat ample amounts milk and dark green leafy vegetables, they may need to complement the diet with appropriate dietary supplements.

Adults need to take care of their bodies and not impact the joints too much with hard exercises or excess weight. Support the joints nutritionally with glucosamine, vitamin C, a good multivitamin, and natural substances that modulate inflammation.

One should not neglect the long-term benefits of glucosamine to maintain joint distances that may otherwise erode, for example, while seeking fast-term temporary relief of aches and pains. By providing those products in both categories as well as overlapping combination products, we can supply a more holistic and sustainable nutritional joint support program.

Many of the Joint Structural Support Products contain varying amounts of glucosamine and/or chondroitin, as well as MSM, Hyaluronic Acid, and other well-known ingredients.

Increased US Vitamin D Recommendations

Chicago Tribune’s report “Don’t overdo vitamin D, calcium, experts warn” focused only on the risks of taking very high doses of these essential nutrients but missed the most important part of the new NIH Institute of Medicine (IOM) report by omitting that there are now higher daily recommended allowances (RDA) for vitamin D intake. It’s uncommon to take toxic amounts of vitamin D but far more common for some to be deficient, with resultant health deficits and increased healthcare costs.

Trib readers didn’t learn that the IOM panel raised vitamin D’s RDA by 50% to 600 IU (800 IU if over age 70), while doubling the tolerable Upper Limit (UL) to 4,000 IU.

In Chicago, it’s already been months since we could make any of the “sunshine vitamin” from sunlight, since the sun must be high enough in the sky so one’s shadow is shorter than his/her height. Darker skin allows less vitamin D production even with adequate sunlight; sunscreen blocks it. Chicagoland residents must rely on fortified foods and dietary supplements as primary sources of vitamin D for over half the year.

The IOM statement that people get enough vitamin D refers only to its conclusion that bone health is the only as yet proven role for this nutrient. Yet the IOM’s European counterpart, the European Food Safety Agency, recognizes an established cause and effect relationship between vitamin D and normal muscle health, immunity, inflammation, reproduction, and cellular health. Researchers have estimated that these additional benefits occur when people take 1,000-2,000 IU daily. Scientific toxicity reviews show safety up to intakes of 10,000 - 20,000 IU daily; multiples of the recently doubled UL.

By ignoring vitamin D’s increased RDAs and other benefits, and publishing broad statements that focus primarily on the unlikely “risks” of vitamin D and calcium supplementation, Tribune readers missed important parts of the IOM report.
