A pediatric dietitian’s review of two popular kids greens supplements.
This post is in partnership with Hiya. I only endorse products I believe in.
I’m in the middle of a serious picky eating phase with my boys. My four-year-old refuses to eat anything green, and my two-year-old is stuck on his favorite beige foods (think: buttered pasta, crackers, rice, and bread). As a mom and pediatric dietitian, I know this is just a phase, and I’m working on expanding their palates, but I can’t help but worry when weeks go by without a single veggie in sight.
Knowing how important vegetables are for health, I started looking for ways to incorporate them into their diet without the usual mealtime battles. Since I’m a big fan of supplementing when kids need it, I decided to compare two popular kids' greens supplements to see how they stack up and if they could help. Here’s what I discovered.
Criteria #1: Formula
| Hiya Daily Greens + Superfoods | SmartyPants Kids Fiber and Veggies | |
| Vegetables | Greens blend, digestion blend, superfoods blend, core development blend, including dozens of organic vegetables and fruits such as broccoli, spinach, beet, acai and more. | Kale, broccoli, and spinach |
| Fiber | 2 grams | 3 grams |
| Dietary restrictions | Vegan, free of nine major allergens, gluten free | Vegan, free of nine major allergens, gluten free |
| Added sugars | 0 grams | 2 grams |
| Dose | 1 scoop | 2 gummies |
Hiya Daily Greens + Superfoods
Hiya Kids Daily Greens + Superfoods is a greens powder made specifically for kids. Unlike other greens powders that are formulated for adults that might include ingredients or dosages that aren’t safe for kids (like caffeine or adaptogens), Hiya’s green powder is packed with 55+ whole food sourced ingredients designed to support kids' brain health, digestion, and overall wellness.
SmartyPants Kids Fiber & Veggies
SmartyPants Kids Fiber & Veggies is a two-in-one supplement that combines greens and fiber. It features an organic blend of kale, broccoli, and spinach, along with 3 grams of prebiotic fiber to support digestion.

Criteria #3: Taste
Hiya Daily Greens + Superfoods
My son seriously thinks this is chocolate milk, and never leaves a drop left in his cup! It’s pretty impressive that Hiya’s Daily Greens+ tastes so great without any added sugars. It has a deliciously chocolatey flavor—none of that earthy, bitter greens taste. You can mix the greens powder into milk or plant-based milk alternatives to create chocolate milk or hot chocolate for your kids. It’s also perfect for blending into smoothies, oatmeal, yogurt, or even baking into breakfast cookies or pancakes. Shaking or blending with an electric frother works best.
SmartyPants Kids Fiber & Veggies
The gummies have a mixed berry flavor and taste fruity and sweet.
Taste Winner: Tied
