1. Boosts Immune System: The OptiBac Immune Support Probiotics contain beneficial bacteria that help to strengthen the body's immune system, making it more resistant to illness and infection.
2. Improves Gut Health: These probiotics promote a healthy balance of bacteria in the gut, which can improve digestion and alleviate symptoms of digestive disorders such as bloating, constipation, and diarrhea.

The Active Ingredient Is: Probiotic Cultures (Lactobacillus rhamnosus Rosell-11, Lactobacillus acidophilus/helveticus Rosell-52, Bifidobacterium longum Rosell-175, Lactococcus lactis Rosell-1058, Bifidobacterium breve Rosell-70, Bifidobacterium bifidum Rosell-71)

Probiotic cultures are live microorganisms that help support normal digestion and immune health through what they do in your gut.

This blend uses multiple strains with supporting fructooligosaccharides to nourish the good bacteria, and the product is vegetarian and free from common allergens.

What Does Probiotic Cultures Do?

Probiotic strains help with gut balance and immune modulation, with evidence suggesting connections to fewer infections and better mucosal defence in healthy people.

These effects line up with EFSA-inspired guidance on gut and immune function, recognising the role of specific strains in supporting normal immune and barrier function. This note cites Dr. Maldonado-Galdeano from the university in relation to probiotic research.
