Probiotic plus vitamin/mineral supplement reduces upper respiratory tract infection incidence and symptoms

Although the role of nutrition in preventing colds and flu has been questioned, a study published in the July 2005 issue of the International Journal of Clinical Pharmacology and Therapeutics found that supplementing with a probiotic plus vitamins and minerals for at least three months reduced the incidence of upper respiratory tract infections as well as lessened their symptoms.

For the current double-blind trial, J. Schrezenmeir, MD and colleagues at the Institute for Physiology and Biochemistry of Nutrition, Federal Research Center for Nutrition and Food in Kiel, Germany enrolled 477 health men and women who had not been vaccinated against influenza. The participants were randomized to receive a placebo or a probiotic containing Lactobacillus gasseri, Bifidobacterium longum and Bifidobacterium bifidum in addition to 13 vitamins and 13 minerals commonly included in multinutrient supplements. The subjects were divided to receive their regimens for 3 months in the spring or 5.5 months in winter through spring. Questionnaires were used by the participants to record respiratory tract infection symptoms. Immune response was evaluated in a group of 120 subjects before and two weeks after the beginning of the study.

It was found that the incidence of viral respiratory tract infections was 13.6 percent lower in the group that received the supplements compared to those who received the placebo. For those who received the supplements and acquired an infection, symptoms were reduced by an average of 19 percent, with this group suffering half the amount of days spent with a fever than the number of days reported by the placebo group. Immune response as determined by white blood cells (particularly T-lymphocytes) was significantly higher in the supplemented group than the placebo group.

The authors conclude that these results provide “some evidence of the positive effects of long-term consumption of a dietary supplement containing probiotic bacteria plus vitamins and minerals on the symptoms of respiratory tract infections, particularly influenza symptoms, and the occurrence of fever in otherwise health adults.” They attribute these benefits to stimulated cellular immunity.

Protocol

Common cold

The common cold is caused by more than 300 serologically distinct viruses. Since there are so many different types, it is impossible to develop a single vaccine effective against them all.

A randomized, double-blind, placebo-controlled clinical trial has shown that zinc gluconate lozenges produce a reduction in the duration of cold symptoms. In this study, patients received zinc lozenges or placebo lozenges every 2 hours for the duration of cold symptoms. The median time to complete resolution of cold symptoms was 4.4 days in the zinc group, compared with 7.6 days in the placebo group.

Another study to test the benefits of zinc gluconate lozenges showed that the time to complete resolution of symptoms was significantly shorter in the zinc group than in the placebo group. The zinc group had significantly fewer days with coughing, headache, hoarseness, nasal congestion, nasal drainage, and sore throat (Mossad et al. 1996). By dissolving two zinc lozenges in the mouth every few hours, the zinc will help inactivate cold viruses multiplying in the throat.

Life Extension Mix is a broad-spectrum multivitamin formula that contains ingredients that have been shown to boost the immune system. Life Extension Mix contains N-acetyl-cysteine, selenium, and other antiviral nutrients. Suggested dose is 9 tablets daily. An additional 600 mg daily of N-acetyl-cysteine may be taken along with the 600 mg contained in Life Extension Mix if there is a need to break up pulmonary mucus.

Zinc Lozenges

Zinc is a mineral essential for formation of superoxide dismutase, one of the body’s most important free radical scavengers and one that cannot be directly supplemented. Zinc also promotes wound healing, immune function, taste sensitivity, protein synthesis, insulin production, and reproduction including organ development and sperm motility.

Dissolving zinc lozenges on the tongue can provide dietary support during the cold and flu season.

Life Flora Capsules

When beneficial intestinal bacteria are destroyed by antibiotics or disease, digestive problems, poor absorption of food and nutrients, fungal infections, and generation of toxins by harmful intestinal bacteria may occur. The bacteria contained in Life Flora™ can recolonize the GI tract with beneficial bacteria, helping to end digestive problems and drive out the harmful, toxic bacteria.
