Cold and flu stomping vitamin D?

No, it’s not a typo!  But it may be time to reach for vitamin D to fight the common cold, instead of the usual standby — vitamin C.A study conducted by the School of Medicine at the University of Colorado, the Children’s Hospital Boston and the Massachusetts General Hospital concluded vitamin D is essential in combating the common cold and flu. The study was reported in the medical journal Archives of Internal Medicine.

According to its lead author Dr. Adit Ginde of the University of Colorado: “The findings of our study support an important role for vitamin D in prevention of common respiratory infections, such as colds and the flu.”

This conclusions flies in the face of modern lore that vitamin C is important for cold prevention. Though vitamin C is widely promoted as a cold fighter, Ginde says the research has not substantiated this endorsement.

Vitamin D is considered the sun vitamin as the body produces it in response to exposure to the sun. Consequently, those living in northern climates — such as Canada – have lower levels than those to the south where the sun’s intensity is higher. Though we get the largest portion of vitamin D from the sun, it can also be found in vegetables and some species of fish.

As a vitamin, D is considered necessary for bone development and maintenance, but recent studies suggested it also boosted the body’s immune system against respiratory ailments. There is even indication it may aid the fight against more serious respiratory afflictions such as tuberculosis

This connection explains the higher incidences of cold and the flu during the winter months when sunshine and consequently vitamin D are at their lowest levels.

Since previous studies involved small test groups, Dr. Ginde and his team conducted a larger, broad-based study to determine how significant this connection was — if it existed at all.

The research group analyzed the blood of 19,000 individuals measuring their vitamin D levels and comparing it to their incidents of respiratory infection.

They found people with lower levels of vitamin D in their blood – 10 nanograms or less per milliliter of blood — were 40% more likely to report a recent respiratory infection than those who had 30 nanograms or more. This ratio remained constant despite the change of seasons.

The connection jumped dramatically for those who suffered from serious respiratory ailments. Asthmatics reported five times more incidents of respiratory problems if their vitamin D was at the lower level and for those suffering from chronic obstructive pulmonary disease (COPD), the incidents were double.

Ginde said, “We want to be careful not to say vitamin D is this wonder drug. But there’s a solid foundation for some of these hypothesis at least in the laboratory.”

Melaleuca Inc.’s vitamin D

Melaleuca provides vitamin D in its Vitality Calcium Complex which also includes calcium, phosphorous and magnesium. Melaleuca’s research recommended dosage ensures that you don’t get too much or too little of these important vitamins and minerals. This is important as too much vitamin D can be as harmful as too little.

The Vitality Calcium Complete is compounded using Melaleuca’s patent-pending oligofructose complex which uniquely binds the vitamins and minerals with organic compounds mimicking how they are found in fruits and vegetables.

One of the major problems encountered with mineral supplements is they are not easily absorbed by the body and tend to crystallize and pass through.

As a result of this new process, Melaleuca minerals remain nine times more soluble in your digestive track than many popular supplements. This increased solubility increases absorption.
