When it comes to multivitamins, two brands that often spark interest are First Day and Hiya.

First Day, an innovative company in the nutritional supplement landscape, prides itself on providing scientifically-supported and meticulously crafted gummy multivitamins. They’re all about enhancing your well-being one gummy at a time.

On the other hand, we have Hiya, another powerhouse company that is well-known for its kid-friendly multivitamins. They believe in providing essential nutrients to support a growing child’s needs.

But which brand truly reigns supreme?

In this article, we’ll dive into the battle between First Day vs Hiya, so you can make an informed decision on which multivitamin brand is better for you and your family.

Importance of Vitamin Supplements

Micronutrient deficiency, a term you may not be too familiar with, refers to a form of malnutrition where people may be consuming enough, or even an excess of food, but not getting the necessary nutrients. And with over 2 billion persons suffering from micronutrient deficiency globally, the need for vitamin supplements has become increasingly important.

The problem with micronutrient deficiency are the symptoms. The symptoms are not as obvious or alarming as that of starvation, but if left unaddressed, can lead to serious health consequences for you and your kids. For example, a deficiency in Vitamin D may result in weaker bones and an increased risk for fractures.

The Essential Role of Vitamin Supplements

So, where do vitamin supplements come into play?

Well, they can help bridge the gap between what our bodies need and what our diets provide. Especially in cases of hidden hunger, people may not even realize they’re missing out on key nutrients. Vitamin supplements can ensure we’re getting the complete spectrum of nutrients our bodies require for optimal health. They serve as an insurance policy, so to speak, against any potential nutritional deficiencies in our daily diet.

Plus, the best multivitamin brands can support multiple bodily functions at once—think bone health, immune support, and energy production to name just a few. Not only can this help us feel better physically, but knowing we’re giving our bodies the nutrients they need can also boost our mental well-being. It’s a win-win situation!

First Day:  The Brand and Its Values

First Day’s mission is to make wellness accessible to all. They pride themselves on using the latest scientific research and high-quality organic ingredients to create multivitamins that actually work. Their goal is to help people feel their best every day, starting with just one gummy.

One thing that sets First Day apart from other supplement brands is its commitment to transparency. They want their customers to know exactly what they’re putting into their bodies, so they provide detailed information about the ingredients and sourcing of each of their products.

For example, First Day boasts a unique approach to sourcing their ingredients. They only use wholesome ingredients – 12 organic fruits and vegetables that are full of antioxidants and phytonutrients.

Not to mention, First Day isn’t just making guesses when it comes to their ingredients. They’ve meticulously sifted through 35,000+ studies on pediatric health. This means they’re not just throwing ingredients together and hoping for the best. Rather, their team, filled with doctors, scientists, and researchers, ensures that the multivitamins are not only effective but also safe for the whole family. Plus, they also confirm that all their products are free from artificial colors, flavors and preservatives, and excess sugar. 

With over 230,000 happy customers, First Day has established itself as a trustworthy and reliable brand in the supplement industry.

Hiya: The Brand and Its Values

Hiya’s primary focus is on providing essential nutrients for children. Similar to First Day, their multivitamins are specifically formulated to support their immunity, growth, and development needs. They also believe in making nutrition fun for kids, which is why they offer tasty chewable options that make taking vitamins easy to take for children. Hiya offers various multivitamins for kids such as Kids Daily Multivitamins, Kids Daily Probiotic, and their new Kids Bedtime Essentials.

First Day Vs Hiya: Nutritional Formula 

When comparing the nutritional content of First Day and Hiya multivitamins, both brands have a comprehensive range of essential vitamins and minerals in their products. However, there are some notable differences.


Both brands are committed to providing the best multivitamins for children, with both their products promising a wide range of essential vitamins and minerals. Also, they share a mutual goal of packaging these nutrients into kid-friendly, easy-to-consume formats, with First Day offering yummy gummy vitamins and Hiya providing tasty chewable options.

However, the similarities end there. When we delve deeper, we uncover quite a few differences in their approach to their ingredients and nutritional content.


First Day seems to take a careful approach to their multivitamins. They use beta carotene as the source of Vitamin A instead of retinyl palmitate which can cause potential risks such as Vitamin A overdose. They also exclude zinc to avoid potential health issues – which after some intense research, we found to be linked with nausea, vomiting and even decreasing copper levels in the body. First Day sweetens their gummies with a small amount of natural organic sugar so our kids don’t get into a sugar craze.

On the other hand, Hiya’s Kids Multivitamins include zinc in their formula. They also use retinyl palmitate as a source of Vitamin A and sweeten their products with monk fruit extract and natural flavors instead of organic sugar.  Now, at first glance, monk fruit may seem like the perfect natural alternative to sugar, but we discovered that this sweetener can cause diarrhea and nausea.

First Day vs Hiya: Price Comparison

When it comes to cost-effectiveness, Hiya truly stands out. With their subscription-based model, maintaining your child’s vitamin intake becomes not only convenient but also surprisingly affordable. 

For only $30 a month, you can ensure your child receives all the essential nutrients they need for healthy growth and development. 

This investment in your child’s health comes without any hidden costs or commitments—simply a straightforward, monthly fee. 

When you break it down, it’s less than a dollar a day to provide your child with top-quality and kid-friendly multivitamins. 

Now, that’s a deal worth considering! 

Plus, with a subscription, there’s no need to remember to reorder every month, making Hiya an effortless and cost-effective choice for busy families.

However, according to some customer reviews, the cancellation process has been reported to be a bit tricky. This could potentially make Hiya less ideal if you prefer to have the flexibility to stop or start your vitamin purchases based on your changing needs. 

On the other hand, with First Day, you have more flexibility in how you purchase your vitamins. They give you the freedom to either subscribe for regular deliveries or make a one-time purchase of $39 if you’d rather not commit to a subscription. This gives you more control over how much you spend and when.

All in all, both First Day and Hiya offer high-quality multivitamins, but it’s crucial to choose the one that fits your lifestyle and budget best.

Our Verdict: Which One Should You Choose?

The decision between First Day vs Hiya is ultimately up to personal preference, but here are some things to consider:

  • If you’re looking for multivitamins for the whole family, with a focus on using high-quality organic ingredients, then First Day may be the best choice for you.
  • If you’re specifically looking for vitamins that cater to your child’s digestive health, with the added benefit of probiotics plus bedtime gummies for sleep, then Hiya may be the way to go.

Ultimately, both First Day and Hiya offer top-quality multivitamins for children.

But First Day’s commitment to providing the best nutritional content for all life stages, along with their flexible purchasing options and decreased risk of vitamin toxicity, makes them slightly better when compared to Hiya. If we had to choose, we’d choose First Day.
