CD-Biotic is a specialty probiotic, formulated to support healthy gastrointestinal flora when certain difficult to control bad bacterial strains are involved. This probiotic was designed to used with CD-Herbal, a powerful blend of herbs, which also targets strains of undesirable flora that are difficult to eradicate. Under certain circumstances and frequently among sensitive individuals, certain strains of bad bacteria become concentrated in the gastrointestinal tract and are very difficult to eradicate using conventional probiotics or drugs. This is especially true if the strain of bacteria is a spore-forming organism. Spores of these types of organisms can lie dormant in the gut following various types of control procedures, only to repopulate when conditions are right. CD-Biotic is a blend of three probiotic strains including Lactobacillus rhamnosus, Lactobacillus plantarum and Saccharomyces boulardii. These three strains of good bacteria have a history of supporting healthy gut flora under difficult circumstances. CD-Biotic, when used with CD-Herbal, forms a concentrated duo that have a profound impact on gastrointestinal flora to support gastrointestinal health. Probiotics are defined scientifically as "living microorganisms that when ingested or locally applied in sufficient numbers, can fill one or more specified, demonstrated functional or health benefit on the host." Probiotics have been called nature's "internal healers" because of their crucial role in the health and functioning of the intestinal tract. Probiotics are actually friendly (desirable and beneficial) bacteria that help keep the flora of the gastrointestinal tract with the correct balance of good and bad organisms. Kirkman recommends taking these products under the supervision of a doctor. Lab testing may be necessary to evaluate progress and any dosage changes required. It is important when using this duo of products together, that dosage instructions are carried out accurately. The typical dosage is one CD-Biotic capsule one hour before lunch and one more near bedtime (two hours after dinner). The CD-Herbal capsules should be taken just before breakfast and two more before dinner.
