A lactic acid strain that produces bioactive tripeptides to support mood balance, sleep quality, and bone health.
What it is
Lactobacillus helveticus is a dairy-associated lactic acid bacterium known for its powerful proteolytic system that releases bioactive peptides during fermentation. Manufactured commercially via bio-fermentation and lyophilisation, L. helveticus hydrolyzes milk proteins into functional molecules. In Velobiotics products, L. helveticus is protected using patented MEP lipid microencapsulation, safeguarding live bacteria against gastric acidity to ensure effective delivery into the intestinal canal.
Also known as: L. helveticus
What it does
- Generates bioactive tripeptides (IPP, VPP) supporting vascular relaxation.
- Promotes emotional stress resilience via gut-brain signaling.
- Enhances dietary calcium bioavailability and bone mineralization.
- Supports gut lining integrity and immune homeostasis.
Amplified by probiotics
Lactobacillus helveticus displays unique biochemical synergy when combined with Bifidobacteria and other Lactobacilli. Its exceptional proteolytic machinery cleaves complex proteins into short-chain peptides and free amino acids, including tryptophan and proline. These peptide cleavage products serve as essential growth factors for companion strains like Bifidobacterium longum, accelerating multi-strain colony establishment. L. helveticus-derived peptides also act as ACE-inhibitory molecules and GABA precursors that modulate gut-brain axis communication. Furthermore, the organic acids produced by L. helveticus lower luminal pH, increasing calcium ion solubility for enhanced bone absorption. Velobiotics MEP microencapsulation preserves L. helveticus viability, allowing sustained enzymatic peptide generation in the upper intestine.
Typical dose
1–10 billion CFU/day
The evidence
Evidence: strongClinical trials demonstrate that Lactobacillus helveticus (often combined with B. longum) significantly reduces anxiety scores, stress-induced cortisol, and sleep disturbance. Studies also confirm its capacity to produce blood pressure-supporting tripeptides and increase bone mineral density markers.
