Effective potency is multi-faceted; not simply measured in milligrams or CFU alone. The measure of a truly potent supplement takes into consideration the clinically-proven dosage and the bioavailability of the dose form.

This ultimately produces an extensive selection of probiotics and enzymes for gastrointestinal health, suitable for even the most sensitive of individuals.

What are Pro-biotics ?

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.

The gut microbiota plays a direct and indirect role in overall health and wellness. However, a healthy intestinal balance of microorganisms can be disrupted by stress, disease, poor nutrition, toxins, and medications. Examples of such medications include antibiotics, immune suppressants, and gastric acid inhibitors. As a result, the intestinal and systemic health will be disturbed. 

Research has shown that diverse probiotic species are able to inhibit the growth and control populations of undesirable microorganisms by competing for nutrients and adhesion sites; producing supportive compounds such as organic acids, hydrogen peroxide, and bacteriocins; and modulating the body’s own healthy immune and inflammatory responses. Probiotic microorganisms maintain and strengthen intestinal barrier function as well as regulate bowel motility. They promote normal colonic blood flow, produce essential nutrients for the colon mucosa, synthesize vitamin K and B vitamins, and facilitate nutrient and mineral absorption, especially calcium, magnesium, and zinc.

Therefore, dietary probiotic supplementation can support the body in restoring and maintaining a healthy, balanced gastrointestinal microbiota.
