bVital pre and probiotic

Dairy-free bacteriophage/probiotic combination formula to support the proliferation of beneficial bacteria in the intestinal tract

bVital pre and probiotic is a specialized bacteriophage formulation combining:

• Four types of phages (as the proprietary bacteriophage blend PrePhage™)
• Seven strains of probiotics
This product is formulated to support the proliferation of beneficial bacteria throughout the small and large intestines in order to promote healthy GI and immune function. This dairy-free formulation is featured in a delayed-release capsule to increase intact delivery to the small intestine by protecting these organisms from stomach acid.

What is a bacteriophage?

Bacteriophages, or simply phages – whose name means to eat or devour in Greek – are benevolent viruses that exclusively infect bacteria. Phages are the most abundant naturally occurring organisms on earth and are relatively benign. We are surrounded by phages, as they can be found virtually everywhere, including in soil, food and drinking water. A single drop of seawater can hold millions of phages and the human body contains billions of them. They prey only on bacteria, never human cells, and bacteria have trouble becoming immune to them. They are considered to be a safe and effective way to help reduce the density of specific pathogenic bacterial populations. Phages continuously change and adapt with their host bacteria to destroy them more effectively. Thus, phage therapy may help to eliminate the vicious cycle of bacteria developing a resistance to antibiotics.

The PrePhage™ mixture in bVital pre and probiotic is a proprietary blend comprised of four bacteriophages, which:
• Are lytic, T4 phages
• Are able to replicate via the lytic cycle only
• Infect and inhibit the growth of E. coli only
• Have been shown to significantly increase bifidobacteria growth

Bacteriophages as prebiotics

Highly specific bacteriophages may be classified as prebiotics since they enhance the growth of beneficial bacteria in the gastrointestinal tract. Beneficial GI bacteria such as bifidobacteria, lactobacillus, and others, are in a constant battle for food and space. Inhibition of the growth of neutral or potentially harmful bacteria creates an availability of space and resources to allow the growth of beneficial organisms.

Advantages of PrePhage™ over traditional prebiotics

Most other prebiotics is non-digestible fibers that often produce the negative side effect of gas and bloating. They may be required in large doses and for prolonged periods, and may not be effective in the small bowel since their activity is localized to the large intestine. In some people, they may also increase the growth of unwanted bacteria in the GI tract.

In contrast, PrePhage™ has the following features:

• No fermentation and therefore no gas or bloating
• Independent of environmental conditions
• Effective in small doses
• Efficacious within hours
• Active in small and large intestines

The inclusion of phages as prebiotics helps to:

• Increase the survivability of probiotics
• Create more space for good bacteria by reducing counts of unwanted bacteria
• Provide a natural way to shift intestinal bacteria toward more beneficial organisms
