What are the ingredients?
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We found the average multivitamin uses outdated science from 50 years ago.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:

Toddler multivitamin gummies with clean ingredients praised for great taste and appeal to picky eaters. Customers said kids 'love them' and ask for more daily. Notable improvements in appetite, mood, and energy reported. Concerns include non-child-resistant lid, occasional taste/smell complaints, and shipping costs to Canada.
My 2 year old loves these vitamins. They’re her treat after she gets ready for the day. They taste amazing and I love the ingredients. The container is super cool too. I love the big lid.
After finding out I had a MTHFR gene mutation I was looking for a good multivitamin to help with methylated vitamins. Since I have 7 kids and they probably have a mutation as well, I got these to help us all. My kiddos take them and don’t complain. I think they’re helping as my blood tests came back in good/normal range.
The best Five star vitamins around. My 10 yr old son has been taking these for 7 yrs now. He loves the gummies that dont have a bad taste. Said, they are like candy. But good for him.
I definitely recommend these to any new toddler Moms out there. No junk in these vitamins.
Why all that sugar needed for kids why?
Since i started with First Day My kids have been More active in the park and at home whether there outside or inside there having a great time with better behaivors and less fuss definitley see a difference than before using First Day, Before FirstDay they showed alot of aggression and fatigue but thanks to First Day They are getting what they need! When they dont eat all there veggies all or even there food :) Thanks alot FirstDay!!! ,My kids love Them before school And come home excited and happy with no fights :) Definitley the Right Choice of Vitamins that kids love ! :)
My grandson has been taking them for two weeks. They seem to be working great for him. He is not hungry all the time and has calmed down and sleeping better.
My kids love these vitamins! I think they have helped improve meltdowns as well and I feel confident they’re getting a good healthy vitamin .
These vitamins are LEGIT. My kids (especially my daughter) used to get sick allllll the time and ever since we started these vitamins almost a year ago they haven’t been sick. It’s extremely impressive because there were some TERRIBLE illnesses going around our neighborhood and church. I’m forever grateful for these vitamins keeping my family healthy!!
My little boys definitely love these vitamins! It feels good to give them something that is nontoxic, yet good tasting!
I watched an online add on the First Day vitamins and decided to try them out. I’ve been a loyal customer ever since. It took under 2 weeks for me to notice the health benefits, and it only took running out for a week and half to see the impact of how much we appreciate the First Day vitamins. You can’t beat the price! My children are happier, and healthier taking this as an added nutritional benefit. My special needs child has been positively impacted by taking the First Day vitamins. Let’s face it, it’s hard to eat right all the time. I highly recommend this as part of your daily vitamins routine and you’ll see the changes within the first 14 days. I’ll continue to support this company and buy our family’s monthly vitamins. A must have in today’s busy parent or person world!
As a a father I often struggle figuring out what healthy options my kids can eat for breakfast, lunch and dinner ! To cut to the chase my kids are just like other kids in that they are such picky eaters. Luckily with First Day gummies I know that my kids are getting proper nutrition everyday! So glad I get these vitamins!
sin duda note cambios, les dio mas hambre a mis pequenos, pense que no les iban agradar por el olor., si dijieron k no eran dulces pero aun asi las comen .. asi que si creo que son diferentes a las wue les compraba, la textura, y eran dulces como gomitas regulares!! sin duda volvere a ordenarlas!
My 10-year-old son has been taking these for the past three months. We are enjoying the vitamins. However, the last batch we got was extremely gooey and sticky, however, he is taking them. I don’t know what happened during shipping, but they are difficult to pull apart so he can take his daily dose, hopefully the next batch will be better.
My son got ADHD diagnosed and he barely eat but nonstop snacks eater. Never finished his food. I thought I supplied him good food and balance with vitamins in veggies but since he took medicine for ADHD, it reduced his appetite. It makes me worried and his weight is too low for kids his age.
I saw FirstDay Kids many times and I thought "Hidden Hunger?? its impossible ". But when I see my son eat less portions every day, I need to do something.
I ordered and subscribes FirstDay kids and at first week I can see my son have his appetite back. When I feed him, he will eat and wont say No. When he feels full enough , he will stop. I keep feed him with balance proteins, veggies and fruits. I know FirstDay already have good vitamins but seeing my son's appetite is back, making me become a happy Mom. He become a happy person and enjoy foods, always requests for apple for his before-bed snack instead of candy/cookies.
I hope this gonna be stay good and help my Son always being a happy kid and love food.
When it comes to my children, I adopt a meticulous approach to selecting the products they consume. I initiate this process with thorough research, examining the ingredients and additives in vitamins and other supplements. This research often leads me to consult Google reviews, which enables me to make informed decisions about the best options for my kids. After several days of deliberation, I concluded that Firstday vitamins were the superior choice. Prior to making a purchase, I contacted their customer support team to assess their responsiveness and helpfulness. I found their team to be exceptionally friendly and supportive, unlike other companies I had interacted with. After selecting Firstday, I placed an order and was impressed by their ongoing communication, which ensured that I was informed about the status of my package until it arrived. Furthermore, after a couple of weeks, they reached out to inquire about my satisfaction and offer any necessary assistance. I highly recommend Firstday vitamins for both children and adults. Their commitment to customer satisfaction and well-being is truly commendable. Thank you, Firstday, for your dedication to ensuring the health and well-being of your customers.
We definitely love this amazing Vitamins for our children’s ! As a mother of 7 I 100 % recommend! Thanks Firstday .
Hola. Soy mama de 7 y Definitivamente nos encantan 100 % recomendado!!! Gracias Firstday
All natural vitamins! This is the only vitamins that we will give to our son, no unnecessary chemicals that you cannot even spell. We always read the ingredients before we purchase anything and this checks all the boxes. First day keeps my son healthy and it helps in building a great immunity. My son is very excited to take it everyday! Its like a reward for him after he eats his breakfast.
I received them in the time frame it said.
Opened one of 3 and they smelt amazing and tasted good.
Comes in cool jars.
First Day was very responsive to my emails and concerns.
They text you to keep you in the loop.
My 4 daughters like them Ages 5-7-9-11.
They almost taste too good to be vitamins.
My 9 year old has been in better moods but too early to tell if it is the gummies. Received Jan15.
Con- takes a while to receive to Canada,Ontario,Brampton.
-had to pay around 33$ more at the Canada Post for border inspections.
It’s all the in the video, but I 100% believe Kids Hiya multivitamin is why my kids have hardly been sick since the fall of 2024 to now. It’s all natural, no bunch of sugar in it, and more importantly, it works!
I love these vitamins and so do my girls. They are no fights or resistance when it is time to take them. This is worth its weight in gold. I hope to be able to continue purchasing these vitamins. They have been a lifesaver. Now if I could just get them to enjoy flossing…..
I never thought first day vitamins could resolve my 2 children's hidden hunger. I am even surprised they are eating new, healthy option foods that I prepare for them. They are more active than before! I could not imagine how these vitamins saved my kids. Notably, they have been sleeping straight through the night and sleeping for 10 hours every day, perfect for their age and body needs. I am delighted to have encountered First Day. You have helped busy moms like me. More power to your company!
Give your family the support they need now, with nutrients for everyday health.
