A friendly probiotic strain that supports your immune system, breathing health, and intimate balance.
What it is
Lactobacillus fermentum is a helpful strain of friendly bacteria found naturally in sourdough, yoghurt, and a healthy human body. It produces natural antioxidants that protect your cells from daily stress. In Velobiotics products, these friendly bacteria wear a protective micro-shield so they pass safely through stomach acid and reach your gut alive.
Also known as: L. fermentum, Limosilactobacillus fermentum
Key benefits
- Supports your body's natural defences so you can recover quickly from daily exertion.
- Helps protect your airways and lungs, keeping your breathing clear.
- Maintains a healthy balance of good bacteria in intimate areas so you stay comfortable.
- Neutralises harmful free radicals in your gut so your digestive lining stays calm.
Amplified by probiotics
Lactobacillus fermentum works alongside other friendly bacteria by producing natural acids and antioxidants in your gut. This lowers gut acidity and removes excess oxygen, creating an ideal home for other good microbes like Bifidobacteria to grow. Protected by a microscopic shield against stomach acid, it settles onto your gut wall to support a strong lining and help your body absorb nutrients smoothly.
Typical dose
1–10 billion live bacteria (CFU) a day
The evidence
Evidence: strongHuman clinical studies show that Lactobacillus fermentum helps lower the frequency and length of common chest and stomach bugs in active adults. Research also confirms it helps maintain a healthy balance of intimate flora and reduces cellular stress.
