Awesome for premature baby

Baby in NICU

My daughter was born, via C-Section, a month early due to some medical complications. Unfortunately, she had to spend 19 days in the NICU. Somehow her blood showed that she got an infection. Doctors aren't sure how this happened when everything is so sterile. The doctors immediately started an IV on our daughter and started her on antibiotics. From what I understand is that antibiotics potentionally can kill good strains of gut bacteria. Having good gut health can help prevent autoimmune diseases and future health issues. With me having 2 autoimmune diseases I wanted to help my daughter start this world on the right foot. So as soon as she got released from the hosptial I started her on Evivo. My daughter is thriving and despite being born a month early is hitting and nailing every milestone as is she was born full term.

This was life-changing for us

My poor baby had such bad colic, always uncomfortable and unsettled. Within 4 days of regular use everything changed. My baby is finally a happy baby! Additionally, his sleep schedule is much more regular and I’m getting a nice stretch of sleep! My baby doesn’t always love taking it with the dropper but it’s worth it, if I could go back my only change would be to take this sooner!

Everything we wanted... and more!

My baby was delivered via c-section and after dealing with multiple issues, including severe reflux, thrush, etc, we were desperate to find a probiotic that could give our baby the peace she needed... and we found that in Evivo! We saw a difference within two weeks, and now at 4 months, our baby girl is shining! Bye bye throw-ups after every feed, so long thrush... and helloooo strong, healthy, warrior child! Thank you, Evivo, for providing such a life-changing, quality product... our baby girl is shining because of you!

Life changing

I can’t recommend Evivo enough! My baby was pooping 8-12 times a day and in terrible pain each time. He was gassy and fussy all day. It was taking all the joy out of being a new mom! Within 3 days of starting Evivo we started to see changes. Our baby was happier, had 3-4 stools a day, less gas, and he even slept better. This was a life changer for us! I recommend Evivo to all my friends with new babies and can’t thank the company enough for making this product. So, so happy my baby is no longer in pain and we can enjoy life together!

Evivo for the win!

These little miracle packets cured my son's colic. Now his gas passes easily, his bowel movements are under control, and thankfully (knock on wood) he has not gotten sick as of yet despite every other person in the house being ill. I’m forever thankful for this product and am about to reorder. If you’re on the fence just order! You’ll be happy you did.

Miracle product

At 9 days old our newborn had a fever and was in the hospital for 3 days with a high dose of antibiotic. He already was fussy but he was miserable with a constant upset stomach and the worst diaper rash I have ever seen. We tried every cream and after doing some research we found Evivo. I tried a probiotic at Target that did nothing for the problem. After hours of screaming one night, we made the first purchase of Evivo. After a week the rash was almost gone and after 2 weeks he did not have colic or upset stomach. He went from pooping every hour to once every other day. We love Evivo and have recommended it to many friends.

Complete game changer

Wow- I cannot recommend Evivo enough. It was a complete game changer for our baby who has had digestive issues since she was born. We tried 3 other pro/pre biotics before giving Evivo a try and although some of those helped, none worked like Evivo. One thing to note- it didn't kick in automatically for us. In fact the first 3 days baby was very fussy, so much so I almost stopped the drops thinking she was allergic to them. After talking to the support line and a doctor, I learned it was her body clearing out her system and gave it one more day. Absolute game changer. She started nursing better, sleeping better, and was overall a happier baby. Thank you Evivo!!

Finally we can relax

We feel safe with Evivo. Our preemie was delivered via emergency c-section and spent 2 weeks on antibiotics. Evivo has truly helped this baby’s wrecked guts and we believe it’s continuing to do so. We feel good about that.

No more bloody stools, and no more crazy elimination diet!

My LO had bloody stools with gross blood every day since 3 weeks old, with no other symptoms - happy baby with healthy weight gain. The pediatrician suspected food protein intolerance and told me to eliminate problematic foods from my diet. By 3 months old, I was on a crazy elimination diet of no dairy, soy, egg, wheat, peanut, coconut, fish, shellfish, oats, rice, peppers, and all seasonings besides salt - still, nothing improved her situation. I was referred to a pediatric GI specialist who conducts probiotic research by my coworker, who recommended Evivo, as it contains the Bifidobacterium for populating the large intestine where she was showing inflammation. The change was obvious after only 2 days! No more blood and I've been able to slowly add all the foods back into my diet within 2 months!

Love love love Evivo

My experience using Evivo was overall amazing! As a new mom, I didn’t know how to help my little one. Then I was introduced to Evivo! I was leary at first, but I could notice a huge difference with my baby girl. I recommend Evivo and mention it to all the mommas I know! Thank you, Evivo, you have been a lifesaver!

Baby in NICU

When we got our NICU baby home after 6 weeks it was clear that he was very colicky and not sleeping more then 1 hour stretches a night and nothing would soothe him. We started using Evivo a few weeks ago and we are already up to 6 hours a night in one stretch. It’s clear he is much more comfortable and happy!! Thank you!

Baby in NICU

After our 24 weeker came home from the NICU it was a no brainer that we were going to continue evivo. It definitely helps her digestive tract and we can’t imagine being off it.

So helpful!

Baby in NICU

My daughter ended up being in the NICU after she was born because she had fluid in her lungs which turned into pneumonia. She was put on a 5-day course of antibiotics. We brought her home and we knew she needed a good probiotic. We started using Evivo and she was less gassy and slept longer. We could tell her stomach was less bloated and she had less discomfort. She also started having a bowel movement at least once a day. Huge difference from when we originally brought her home. Highly recommend.

So much relief for my little guy!

Baby in NICU

Evivo has been exactly what my little guy needed! After spending his first 3 weeks of life in the NICU and having multiple rounds of antibiotics, his digestive system was not functioning normal and I knew his gut health needed help. After trying a few probiotics without any change, I finally tried Evivo and I wish I would’ve started here! His digestive system is functioning normal and he seems so much more comfortable all day long. So thankful for this company!

Worth every penny!

Baby in NICU

As a microbiome scientist, I have known about Evivo for the past 2 years and have been impressed with the strength of the scientific evidence behind it. I purchased it for my daughter prior to her birth and she started taking it at 5 days old. She spent 2 days after her birth in the NICU and received 2 doses of IV antibiotics, so I worried this would wipe out any good bugs she received during vaginal delivery. However, now she is a very happy and healthy, minimally fussy baby, and I imagine Evivo helped with that! She regained her birth weight within a week of taking it. Proper establishment of the gut microbiome is critical to proper immune system education and development and Evivo has strong evidence that it does this, especially in breastfed babies. The investment in my daughter's future health is well worth the price!

Individual results may vary. Evivo is intended for infants consuming some HMO in their diet. If you have questions concerning your baby's health i.e allergies, immunocompromised, please consult with your physician before use.

Frequently Asked Questions

Only Evivo contains B. infantis EVC001, an infant-specific strain that has evolved with humans for millions of years to work with human milk, and should be naturally found in the infant gut. B. infantis EVC001 uses the HMOs (human milk oligosaccharides) in breast milk to colonize (grow & thrive), favorably changing the gut biochemistry to significantly reduce potentially harmful bacteria and intestinal inflammation, both of which have been linked to increased risk of short- and long-term health problems. Evivo paired with a human milk diet creates a protective infant gut environment and helps guide immune development towards healthy function, thus setting a baby on a lifepath of health.  

Not all bifidobacteria are adapted to the gut or can use HMOs (human milk oligosaccharides). For example, B. lactis (e.g. BB-12), cannot use HMOs. While B. infantis is the most adept at utilizing HMOs, the capacity to utilize HMOs is very strain dependent. Most infant probiotics that contain a B. infantis strain are H5 negative, meaning they have mutations in the H5 gene cluster which renders these strains unable to efficiently access HMOs. Only EVC001, was found to contain a fully functional H5 gene cluster that encodes for a critically important ABC transporter providing a mechanism that brings core HMOs into the bacterial cell, allowing it to transport and fully metabolize HMOs in the infant gut. Read more here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7690671/

All infants should naturally have B. infantis in their microbiomes as a natural process part of their development, but 90% of babies in the US no longer have B. infantis due to high antibiotic use, and modern birthing and feeding practices. Evivo is recommended for all human or mix-fed (human milk + formula) babies, and in particular: Newborns exposed to antibiotics or of mothers treated with perinatal antibiotics E.g., Born by C-section, infants of GBS strep-positive mothers and cases of chorioamnionitis. Also, infants with a family history of food allergy, asthma, eczema, or autoimmune disease

Evivo is a Food for Special Dietary Use (FSDU), manufactured in the USA, and meets all FDA regulations for food products. Evivo is the only product in this category designated as a FSDU given its unique and critical role of providing the functional capacity to metabolize HMO, a foundational part of human milk that optimizes the principal nutrition for newborns. Additionally, within the FDA, the Office of Food Additive Safety oversees a process called GRAS status for many types of products, including Evivo. These products must complete an extensive process of scientific and data review by independent qualified experts, who are assessing whether the product is safe under the conditions of its intended use. Evivo gained GRAS status for use with both term and preterm infants after successfully completing this process, with consensus by all independent qualified experts. 

Evivo contains lactose derived from dairy. Lactose is the carbohydrate portion of milk. Lactose is naturally present in human milk, which is why we chose to use it in Evivo. The milk protein and other components are separated to produce high-purity lactose. 

When making Evivo, one of the components of the fermentation media contains broken pieces of soy and casein (peptides). These peptides are consumed by the bacteria when growing. At the end of the process, the media is discarded. 

We do not expect any intact milk protein, soy or casein protein in the final product but cannot guarantee it. Notably, results have come negative for milk, soy, or casein protein in the instances when we tested the product.
