There are millions of bacteria living inside you, forming an internal world which is often referred to as your microbiome.  There is a huge amount of ongoing research dedicated to investigating the many ways the microbiome may influence health and wellbeing. Many scientists believe that each bacterium has a different role to play.  At Natures Aid, our Microbiome Range is based on this scientific research. Our experts formulate each product by carefully selecting bacteria and nutrients to create unique and targeted supplements. Our award-winning products are manufactured to the highest standards; OptiGUT-C was a finalist in the Best Probiotic of the Year category, in the prestigious NutraIngredients European Awards 2019.

OptiGUT-C combines a unique blend of bacteria with prune, inulin fibre and calcium to support digestion.* Using carefully selected good bacteria and specific nutrients, our OptiGUT-C microbiome supplement has been carefully formulated by our expert nutritionists. This product combines scientifically researched bacteria with Inulin (a prebiotic fibre), Magnesium, Prune and Calcium. OptiGUT-C can safely be used by adults and children from the age of two.

OptiGUT-C utilises a unique blend of three species of bacteria that work together in synergy: Lactobacillus plantarum, Lactobacillus rhamnosus and Bifidobacteria animalis subspecies lactis. At Natures Aid, we select bacteria that are bile and gastric acid resistant and have been proven to colonise your microbiome after oral supplementation. Every teaspoon provides 15 billion selected bacteria and 3g of prebiotic fibre.

The carefully selected nutrients chosen for OptiGUT-C are:

  • Calcium – to support the normal function of digestive enzymes to support healthy digestion.
  • Magnesium – to support normal muscle function, including those in the bowel.
  • Inulin – a source of prebiotic fibre, extracted from raw fruits and vegetables, thought to provide a food source for the bacteria of your microbiome.

This vegan friendly microbiome supplement is a pleasant tasting powder and can be taken either directly or mixed into a cold drink or food. Manufactured to the highest standards, you can rest assured OptiGUT-C is free from such as gluten, wheat, yeast, dairy, nuts, and salt. Even better, OptiGUT-C requires no refrigeration.
