IFF has introduced a new probiotic supplement brand called GutABAlite, which features the Levilactobacillus brevis LBR-6108 strain. The product is designed to support metabolic health by producing GABA within the gut.
Why it matters
As interest in metabolic health grows, this probiotic offers a new approach to managing glucose exposure and insulin sensitivity. The strain functions by increasing short-chain fatty acids, though its effects are not permanent and diminish after use ends.
A six-week study observed that Levilactobacillus brevis LBR-6108 reduced daily glucose exposure, fasting insulin by approximately 18%, and HOMA-IR by about 20% compared to baseline. Researchers noted that these metabolic benefits decreased after participants stopped supplementation.

IFF
An ingredient manufacturer that develops probiotic strains and solutions for the food and supplement industries.
The details
The probiotic works by utilizing the strain Levilactobacillus brevis LBR-6108 to produce GABA and elevate short-chain fatty acids in the gut environment. This process is intended to assist in modulating metabolic markers. The manufacturer plans to incorporate this ingredient into various functional foods and dietary supplement applications.
Timeline
The clinical study evaluating glucose and insulin measures lasted 6 weeks.
The probiotic strain will be showcased at SupplySide Global from October 28-30, 2026.
Health Landscape
This development aligns with the industry-wide trend of targeting metabolic health through gut-brain axis research and microbial interventions. It represents a growing shift toward functional ingredients designed to influence systemic glucose management.
If you are managing metabolic concerns, discuss with your doctor whether probiotic support is appropriate for your specific health plan. Be aware that these benefits appear dependent on ongoing intake, and evidence regarding long-term metabolic outcomes remains limited.
The takeaway
Probiotics like Levilactobacillus brevis LBR-6108 may offer a supplemental way to help maintain healthy fasting insulin and glucose levels. Always consult your physician before adding new supplements to your routine to ensure they do not interfere with existing metabolic care plans.
