Three Keys To A Healthy Gut Microbiome

Our powerful 3-in-1 combination of prebioticsprobiotics and postbiotics work together to promote a healthy gut microbiome, which is essential for maintaining good health in children. A healthy gut microbiome plays a key role in immunity, cognitive function, respiratory health and heart health - and can also help prevent a variety of health issues, including allergies, asthma, eczema and obesity.

A container of kids probiotics, a red and yellow kids’ toothbrush, and a green turtle-shaped object are placed on a white bathroom counter with candles in the background.

Probiotics

Probiotics are a healthy type of bacteria that live in the gut. They not only aid with digestion, but also improve overall immunity. Probiotics also aid in oral health, by helping reduce plaque, gingivitis and cavity-causing bacteria.

A container of First Day Kids Pre + Post Probiotics lies on a wooden board with whole and sliced kiwis, two yellow star-shaped gummies, a plant, and a white cup nearby. The scene is bright and colorful.

Prebiotics

Attack bathroom accidents at the source. Think of prebiotics as a type of "food" for probiotics, helping  them flourish & recover. When probiotics are thriving, they can help with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), two leading causes of accidents.

A container labeled first day kids pre, post, and probiotic sits on a marble countertop with fresh vegetables, lettuce, tomatoes, and a halved lemon on a wooden cake stand in the background.

Postbiotics

We included postbiotics, a natural byproduct of probiotics, to help kid’s bodies maintain a healthy immune response.  Studies have shown an increased antibody response to seasonal illnesses, as well as a decrease in symptoms from the common cold!

Why do you have less than 100% of daily values?

Remember the old adage "more isn't always better"? Many vitamins today use cheap chemicals that our bodies can't absorb in amounts that are much higher than we actually need! In the long term, taking these sorts of vitamins can be harmful to health because our bodies have a tough time getting rid of the excess.

Take plants as an example. Overwatering your plants can damage their roots, wilt the leaves, and ruin their growth. That's why First Day focuses on being a nourishing vitamin filling in the gaps, not overloading you with nutrients.

So, we've consciously formulated our vitamin around what we most commonly lack. Then we made our gummy to fill the gaps in our everyday needs with the finest ingredients.

What else is different about First Day?

We set out by asking the unaddressed questions in the industry. What are supplements really doing for us? Why are they made the way they are?

We found the average multivitamin uses outdated science from 50 years ago.

To separate truth from fiction, our team of experts investigated thousands of clinical studies. That’s why we use the latest science and source the most absorbable ingredients from all around the world so your vitamins are actually working for you and your health.

Should I subscribe if I've never tried First Day before?

Healthy habits are hard to start let alone maintain! We wanted to make it as simple as one-click to building healthy foundations. With your subscription, you get a discount on every order for being a loyal First Day family member! Plus, cancelling a subscription is easy.

For every order, we also have a satisfaction guarantee so you can rest assured knowing we'll always have your back!

Which scientific studies does First Day look at?

Micronutrients, absorption rate, and more! We've combed through the scientific studies so that you don't have to. But if you want to peruse, check out these scientific studies for yourself:

Prayers answered!

I hesitated for a month on whether to invest in these vitamins and the prebiotic. I'm so glad I took a leap of faith because it is the health of my 2 year old grandson . He is a terrible eater that displays some of the key hidden hunger examples. I'm happy to report we have seen a big difference in his eating habits! Hoping to afford the upkeep on providing these for him...he loves them!

Changed her life, thank you.

I just want to say that this vitamin has been amazing so far. I had a very fussy eater who is now eating more and trying more things. I have tried other vitamins before but the issue was always that she wouldn't like them so she wouldn't eat them. I have also been using the belly biotic and my daughter went from having little hard pellets that was hard for her to pass to having a normal looking number 2. Thank you so much for this product. I will continue to use the combo of the multi and belly biotic.

Wasn’t a winner for us unfortunately

My kid hates the taste of these (but will eat the multivitamin) so I have to make him eat them to see if it helps with his stomach/accidents. We gave it 3-4 months and didn’t notice a difference so I won’t be reordering.

Helps Digestion!

These are AWESOME! My son has always had gut issues and these gummies WORK for every other day pooping. He was only pooping once a week if even that before taking these gummies. I’m so grateful!

The actual best!

My daughter had constipation issues for as long as I can remember. We had tried everything! We tried probiotic powder in her water, miralax, Senna, and she was being managed by a GI specialist. I ended up starting her on the First Day 3-in-1 probiotic and she is now off all prescription medications, no longer has to see her GI specialist, and most importantly is able to pass stool regularly, on her own, without any pain! I never leave reviews on anything - but this was such a game-changer for us.

Kids love them

My kids love these vitamins! They always ask for them if I forget to give them to them. My only complaint is some of the vitamins come to us and they are dry and hard. We’ve had bags where they are soft and chewy and others that just seem old and dry. My kids don’t seem to care too much if they are dry but I feel like for the amount of money I’m paying for them the should all be soft. We came from a dry vitamin so I would expect a gummy to be squishy like a true gummy. Also customer service is fine. We’ve had a few order mix ups and they are semi consistent with responding. Again coming from another company where they never messed up an order and had excellent response times, just kind of makes me annoyed because of how expensive these vitamins are.

Best ever!

I was hesitant about giving my kiddo this - she’s never done a gummy probiotic. She LOVES these and would eat more than two if she could! A no brainer!

Tummy Troubles Gone

My 9 and 11 yr old kiddos love these gummies. They both were having a lot of tummy troubles with gas and discomfort. We've been using the multi-vitamin for years so when I saw the pre + pro biotic gummy option, I was thrilled. It has completely erradicated their gas and discomfort. They love the flavor too and it's not a fight to get them to take their new gummies. I could not recommend this enough!

Worth it!

Even if you can't SEE what this product is doing for your child, be assured it IS doing it's job!
I've been buying these for my 7 year old grandson quite a few years now, beginning with the daily vitamins. I believe so much in this product and this company, I literally drive over to my grandsons home every night to give them to him. He is on the spectrum and is very picky! I originally tried another company because, to be totally transparent, they were a bit less expensive, however, he refused to eat them. I decided no matter how inexpensive they were, if he wasn't eating them, then I was basically throwing my money down the drain and returned to first day.
He was pretty happy and said, "mimi! You got me the good kind again!" THAT is a high endorsement!
Thank you, First Day!

A happy mimi and a happier and healthier 7 year old

no more accidents

We were having numerous #2 accidents at school. Not a full accident, just skid marks and occasionally one turd (petrified by the time he came home).
We were furious, how could this guy keep doing this? He knows how to wipe and go when it's time...
BUT that all changed after we got him on this probiotics. We already use the daily vitamins which we all love. It's amazing for me to say but I can't remember the last time he had an accident. His underwear is clean everyday and wiping is less messy for him. I've always been a believer in probiotics as I take them myself, but super glad for this kid option. PLUS he loves taking them each night after dinner.

Easy and effective

My entire family takes the multivitamin and probiotics. Family of 6. It has been an easy and effective way for us to enhance wellness. No one complains about taking them and it gives this momma relief to know I am supporting our nutrition and immunity. Before purchasing, it was great to have the reviews to read to help with the decision to purchase. I am so happy with our regimen and we are about 6 months or so in. I also spoke to customer service about finding the best bundling package to make it more cost effective with such a large family. The customer service support is just beyond. Personable, fast, effective and solved my concerns/issues. I am very impressed with this company. Great product and service.

1 We offer a 45-day satisfaction guarantee for returns. It covers 45 days starting from the day that you place an order and includes only the very first purchase of any product so that families can try our gummies - for any reason you aren't happy with your vitamins.
