I would consider myself a seasoned probiotic user yet I still find the dazzling array of products on the market quite confusing! So full marks to Optibac Probiotic (OP) for providing a free, pre-booked telephone consultation service with one of their friendly and professional in-house nutritionists who recommended the best OP products for my needs. There was no hard-sell or pressure to buy then and there which I appreciated. As a result, I purchased a couple of OP products that arrived quickly and nicely packaged. With regards to the actual products (including the OP Every Day Extra), it is early days but the results so far are impressive and I have experienced none of the digestive issues that I typically encounter when starting a new probiotic range. Overall, an 'optimal' product and service from Optibac Probiotics - thank you!
