Mary Ruth ships expired product

Check the bottom of your probiotic bottle. Two of my three are for 06/2024. This means what when it shipped on 26 May, Mary Ruth's shipped expired product.

Not a great taste and very oily

I should have read the reviews first before buying this. They have changed the formula. I’m not impressed. I gave it to my son and he immediately spit it out. So I taste it and it was very oily and tastes awful.

New formula is horrible!

I loved the old formula. No taste and was easy to give to my kids without them knowing. Now it comes out with brown spots and has a taste so my kids won’t take it. Please bring back the old formula. In the mean time I’ll have to try to find another product.

I also decided to pour out to see why I kept getting brown spots in the dropper. Not sure if it’s mold or wet, but definitely looks disgusting.

Do not like the new formula with oil

I loved the original probiotic drops and our entire family would take this probiotic including my young kids. They recently changed the formula and it now has oil in it. I don’t love it but the taste is tolerable. My kids however absolutely hated it so I will sadly have to find a new probiotic for them. I really hope they go back to the original truly flavorless and clear drops/formula.

Switched formulas taste like oil

I used to love this product but they switched formulas and it now taste like oil. I don’t want oil in my probiotic, so unsure why they thought this am was a good idea.

Have A Question? Great, Ask Us!

Really. We are here to answer any question you may have.

I noticed some changes to this liquid probiotic. What’s different?

There have been some updates to this product, and we are so excited about these changes as they are in line with many requests we’ve gotten over the years! First things first, we are thrilled to share that we are now including the CFU count! We know that the CFU is a meaningful piece of information for people selecting a probiotic product, and we are happy to be able to include it in our Supplement Fact Panel. Additionally, we are excited that we have added the probiotic strain Bacillus coagulans Unique IS-2® to the formula. We know that customers often look for specific strain types to guide their decisions when choosing a probiotic product, and we are happy to include this clinically studied, spore-forming probiotic in our proprietary probiotic blend, as research across all ages shows that this strain supports with digestion, gut health, and immune function! This proprietary probiotic blend now also has a new carrier liquid: MCT oil! With the mild, virtually flavorlessness of MCT oil the taste is very neutral and light, though you can expect a difference in the viscosity. One of the great benefits of this change is improved shelf and temperature stability; refrigeration not required! You’ll also notice some cosmetic changes to our packaging, but most excitingly, we are now using marked pipettes for easier and more precise dosing (no more counting out 60 drops)! This also means all the Suggested Use and Serving Sizes have been updated to mL measurements.

How should I use this? Can I take it with drinks or food?

Our liquid probiotic is easy to take directly or can be added to another cold liquid. Based on your preference, some prefer to add it to the Liquid Morning Multivitamin in the morning, some prefer to take it later in the day or as recommended by your physician or healthcare professional.

Can my kids use the Liquid Probiotics too?

In general, everyone — children and adults — should check with their physician, pediatrician, or healthcare professional before beginning any new wellness supplement to make sure the supplement is suitable for their health. Your physician, pediatrician, or healthcare professional knows you and/or your children best, knows what other supplements or prescriptions you or your child are already on, as well as knowing if you, or your child, are facing any health challenges. If your child’s physician, pediatrician or healthcare professional feels the probiotics are suitable for the child, we recommend considering the dosages, broken down by age, on the box and label of the probiotics. Additionally, your respective provider can assist you in determining the appropriate dosage for your child.

What are the differences between the liquid probiotics, probiotic gummies, capsule probiotics and probiotic powders?

That is a great question! We have a variety of probiotics available for many reasons. We believe that you know what is best for your specific needs, and we want to provide you with the choice to pick what probiotic would best suit your goals, as well as the way that you prefer to take probiotics. Our liquids are easy to take on their own or add to a beverage, the gummies are great for those who prefer a tasty gummy supplement, and many of our capsules and powders are also formulated with specific benefits in mind. If you aren’t sure which probiotic is best for your needs, we recommend you check with your physician or healthcare professional to assist you in determining which probiotic and dosage is suitable for you!
