Probiotics and prebiotics

A probiotic (aka probiotics) is a supplement containing live bacteria that are beneficial for your health. A lot of probiotics occur naturally in fermented or yeast-fed foods, such as sauerkraut and yogurt. Probiotics are often resistant to gastric acid and reach the intestines alive, where they do most of their work. Some bacteria colonise the intestines and become part of your own gut flora. Other probiotics are merely short-term visitors, but still perform their tasks during their temporary stay.

Prebiotics are nutrients (often plant-based fibres) for healthy intestinal bacteria that contribute to human health. These bacteria help support digestion and keep the intestines healthy. Prebiotic fibres feed a balanced mix of intestinal bacteria that support regular bowel function.

BiOptimizers Leaky Gut Guardian: both pre- and probiotics

Leaky Gut Guardian contains three carefully selected types of probiotic bacteria along with the prebiotic fibre to support them. These bacteria are Lactobacillus Rhamnosus, Gasseri and Helveticus. The prebiotic fibres we use are inulin and isomalto-oligosaccharides (Vitafiber). This combination of bacteria and fibre is designed to permanently change your intestinal flora.

Immunised egg powder
BiOptimizers Leaky Gut Guardian contains egg powder from immunised eggs. The egg powder contains IgY, antibodies made by birds.

Two formulas with different flavours
Leaky Gut Guardian is available in the flavours Chocolate and Vanilla. The chocolate flavour contains beef collagen and beef bone broth. The vanilla flavour doesn't contain these ingredients and is therefore suitable for vegetarians.
