Inside every one of us is an internal world known as your microbiome. This fascinating world has been extensively research in recent years, primarily investigating the many ways it may impact health and wellbeing. At Natures Aid, our inhouse experts have crafted a specialist range of microbiome supplements based on this research. Each product in our Microbiome Range has been individually formulated using by carefully selected bacteria and complimentary nutrients to create unique and targeted supplements.

Our OptiGUT-D microbiome supplement combines Saccharomyces boulardii with carefully selected bacteria, Vitamin A, L-Glutamine and Calcium to support your digestion.*

OptiGUT-D utilises Saccharomyces boulardii, a friendly yeast and one of the most extensively researched strains available. Sacchromyces boulardii has been combined with 3 carefully selected strains of bacteria: Lactobacillus casei, Lactobacillus rhamnosus and Streptococcus thermophilus, creating a unique and targeted microbiotic blend. The specially selected bacteria we use have been proven to not only be bile and gastric acid resistant, but to also colonise the microbiome after swallowing.

OptiGUT-D also includes specially selected nutrients, including L-Glutamine, Vitamin A and calcium.

  • Calcium supports the normal function of digestive enzymes, to support healthy digestion.
  • Vitamin A supports the normal function of the immune system and the maintenance of the mucous membranes which line many body cavities, including the gut.
  • L-Glutamine is a ‘conditional’ amino acid, which means it may become ‘essential’ during periods of stress or illness.

OptiGUT-D is a vegan friendly capsule, which can be safely used by adults and children over the age of 6. You can rest assured that OptiGUT-D is also free from gluten, wheat, yeast, dairy, and nuts. Even better, as Nature Aid we only select bacteria that are stable at room temperature, there is no need to refrigerate this product.

*Calcium supports normal function of digestive enzymes.
