About the Author

Darren Grant is the Founder and Managing Director of Probiotic.ie, Ireland’s specialist retailer for clinically formulated probiotics and high-quality food supplements. He is the sole official distributor in Ireland and the UK of the original De Simone formulation, including CDS22-formula.


With over a decade of experience in supplement distribution, formulation analysis and regulatory compliance, Darren works directly with manufacturers and clinical experts to review probiotic strains (including L. rhamnosus GG and Saccharomyces boulardii), CFU counts, ingredient quality and safety standards before products are listed.


His guides reference recognised authorities such as Cochrane reviews, NHS guidance, the Food Safety Authority of Ireland (FSAI) and HPRA frameworks where relevant. Content is written to help Irish consumers understand strains, dosages (for example berberine 500 mg or vitamin D3 2000 IU), and safety considerations before purchasing.
