What are Hiya vs First Day Vitamins?

Hiya Vitamins are a child-specific multivitamin supplement recommended for children two years old and above. These were specifically formulated to address key aspects of childhood, namely healthy growth in terms of height and weight, mental and physical development, and strengthened immunity against viruses and other potential infections.

Hiya Vitamins also address growing concerns regarding excessive sugar consumption among children, juvenile diabetes, and juvenile obesity as these are sweetened with monkfruit extract rather than cane or beet sugar.

First Day

First Day’s kids’ formulation has just nine key nutrients – which isn’t really a lot considering the massive nutritional needs of children in the growing-up years. We also noticed that your child needs two gums a day. Another thing that makes us uneasy about First Day is the fact that its marketing material claims that it can reduce the symptoms of ADHD – a claim that has yet to be confirmed by the US FDA.

Winner – Hiya! Hiya gets the plus points here between First Day Vitamins vs Hiya.



In terms of flavor and whether or not it can easily be swallowed, Hiya scores well among both parents and children. Also, the fact that it is sweetened with monkfruit extract as opposed to sugar means it is completely sugar-free which means it can safely be taken by children with juvenile diabetes. We also like the fact that, being a one-a-day vitamin and a non-sugar-based one at that, it staves off juvenile obesity.

First Day

While First Day claims that their product isn’t made with animal gelatin, parents may not be so keen as to allow their children to keep taking it as it poses a choking hazard, especially to younger children. Likewise, despite its claims of being low-sugar, it still has around 2g of sugar per gummy – making it more like candy than a nutritional supplement.
