New formula is disgusting, old formula was amazing!!

Massively disappointed in Mary Ruth taking their BEST product and making it gross and indelible. I used to put a dropper full in my kids milk or water or whatever and they could not detect it. It was clear and odorless and had not taste. The NEW formula is THICK, has a weird color and smells rancid. I tried to sneak it in my kids milk and she actually gagged and spit it out and said her milk tasted rotten. It also is extremely oily and the oil pools up and floats on top of any food or drink you add these drops to. I’m so sad our favorite product is ruined. Mary Ruth please bring back the old formula!

The new formula is awful

My kids used to the love the water based formula and would take it happily. The oil based one is terrible. I am really sad they changed this because my kids were so happy to take the original version

New formula is the worst

I know MCT oil is becoming popular now, however when mixed in a drink all it does is get stuck to the sides of the cup or any plastic piece. I do not know if it affects how much is actually absorbed. I mix this in my kids water bottles but if you use even slightly cool water it gets stuck on the sides forget it if your kid likes to drink a beverage with ice. Also the MCT oil leaks and makes the bottle/dropper so greasy. Poor choice Mary Ruth! I used to tell everyone about this product.

Change it back!!!

My son does not like the oil base! Please offer both!! This is the only way I could get it in his water. I’m sooooo sad😔

The formula changed

My daughter is having a hard time taking it now that the formula changed. It is super heavy and oily.

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.

Why are probiotics important for my child?

Developing a healthy microbiome is an important factor for immunity, digestion, and overall health. Several factors can impact the microbiome. Building a good foundation for your child during their early development, with probiotic strains that may help support digestion, gut health, and immunity, which may support their overall health. Adding a probiotic supplement to your child’s diet may be positive for their health, but we always recommend doing so under the recommendation of your physician, since each child varies in their health needs. Your child’s physician, pediatrician or healthcare professional can help you determine if the probiotics are suitable for your child and, if so, what constitutes an appropriate dosage.

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 child’s 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 your child prefers 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 child’s needs, we recommend you check with your physician or healthcare professional to assist you in determining which probiotic and dosage is suitable!
