Total CFU (Probiotics)
Live microorganisms that provide health benefits when consumed.
Also known as: Probiotics • Colony Forming Units
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.
| Purpose | Dose | Notes |
|---|---|---|
| General Wellness | 1-10 billion CFU | For daily maintenance of gut health. |
| Specific Health Concerns | 10-50 billion CFU or higher | Higher 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.
With or Without Food
Some evidence suggests taking probiotics with a small amount of fat may improve survival of the bacteria.
