B. lactis (transit time)
A probiotic strain studied for its ability to improve gut motility and reduce transit time.
Also known as: Bifidobacterium animalis subsp. lactis • HN019
Overview
Bifidobacterium lactis, especially the strain HN019, is a probiotic that has been clinically shown to support healthy gut motility. It helps to reduce the time it takes for food to travel through the digestive system (whole gut transit time). This can be particularly beneficial for individuals experiencing occasional constipation and associated symptoms like bloating and discomfort.
Key Benefits
Decreases Gut Transit Time
Clinical studies have demonstrated that B. lactis HN019 can significantly decrease whole gut transit time, promoting more regular bowel movements.
Relieves Occasional Constipation
By improving gut motility, this strain can help alleviate symptoms of functional constipation.
Supports a Healthy Microbiome
B. lactis is a beneficial bacterium that contributes to a healthy and balanced gut microbial environment.
Dosage & How to Take
Dose-response studies on B. lactis HN019 show that even low doses can be effective, with higher doses providing a greater effect on transit time.
| Purpose | Dose | Notes |
|---|---|---|
| Improving Gut Transit Time | 1-10 Billion CFU/day | Strain HN019 is well-researched for this benefit. |
| General Digestive Support | 5-20 Billion CFU/day | Often included in multi-strain probiotic formulas. |
Best Time to Take
Consistent daily intake is recommended for best results.
