Overview

Probiotics are live bacteria and yeasts that are good for you, especially your digestive system. Total CFU (Colony Forming Units) is the measure of viable cells in a probiotic supplement. A higher CFU count does not necessarily mean a better product; the specific strains and their research backing are more important.

Key Benefits

Improved Gut Health

Helps to restore the natural balance of gut bacteria, which can be disrupted by illness, medication, or poor diet.

Enhanced Immune Function

A healthy gut microbiome contributes to a strong immune system, and probiotics can help to support this.

Better Digestion

Can help to alleviate symptoms of digestive issues like bloating, gas, and diarrhea.

Dosage & How to Take

Probiotic dosage is highly variable and depends on the specific strains and the intended use. A general dose is between 1-20 billion CFU per day for maintaining digestive health.

PurposeDoseNotes
General Wellness1-10 billion CFUFor daily maintenance of gut health.
Specific Health Concerns10-50 billion CFU or higherHigher doses may be used for specific conditions, as recommended by a healthcare provider.

Best Time to Take

Often recommended to be taken on an empty stomach, about 30 minutes before a meal.
