Your experience matters to us! Just know that we have a full money-back guarantee so while, high-potency probiotics are expensive to produce, if you don't get the results you're looking for, you get your money back! Most companies don't do that but for over 20 years we have had an excellent track record and rarely get returns. Thank you for taking the time to leave a review.

Thank you for that feedback! We know how important it is to maintain momentum in your wellness journey. Fast and easy to track shipping is part of that commitment and I apologize we missed on that part.

Thank you! We do run monthly promos on various items and guarantee results or your money-back!! We like to say the most expensive supplements are the ones that don't work!

The black background is gone on the website. It was chosen initially because the black screens are easier on the eyes and also use less energy, so from a eye health and environmental standpoint it was good. We did not change the color of the label but on the new website have added extra large bottle images to help with reading the font on the labels. Thanks for the feedback!
