This post is in partnership with Hiya. I only endorse products I believe in and use with my own family.

I look forward to the holiday season every year—the twinkling lights, the warm gingerbread cookies, and all the cheerful festive tunes. But to be honest, it’s also the time when everyone seems to come down with the sniffles and my family starts to feel run down. As a busy mom of two, the last thing I want is to be stuck at home and missing out on all the holiday fun.

This year, I'm on a mission to keep my kids healthy and give their immune systems a little extra support. I decided to look into two popular immune support supplements to see how they compare. Here’s my take on Hiya’s Kids Daily Immune and Emergen-C Kidz Zero Sugar Daily Immune Support. 

Criteria #1: Formula

When it comes to immune support, the most important factor is the ingredients that actually improve immune function. 

	Hiya Kids Daily Immune	Emergen-C Kidz Zero Sugar Daily Immune
Immune-boosting nutrients	Vitamin C, vitamin E, zinc, selenium, beta-glucans, immunity fruit blend including organic elderberry juice extract	Vitamin C, zinc, vitamin B6
Added Sugar	0 grams	0 grams
Dose	1 chewable	3 gummies
Safety	Third-party testing on every batch, free of artificial dyes, gummy additives, added sugars, gluten, dairy, and GMOs	NSF certified, gluten-free, no FD&C dyes and caffeine

Hiya Kids Daily Immune

Hiya’s Kids Daily Immune features a fruit blend rich in nutrients to keep kids feeling their best (think organic sweet potato, apple, camu camu, and organic elderberry!). I also love that it contains zero added sugar. Instead, it’s sweetened with sorbitol, fruit powder, and monk fruit (a superfruit that’s 100-250 times sweeter than sugar).

Plus, Hiya is packed with these immune-supporting nutrients:

• Vitamin C: This vitamin doubles as an antioxidant and protects our cells from free radicals which can cause oxidative stress (¹) and damage. (²) It plays a role in collagen production, a protein that helps with healing. (³) Vitamin C also helps the body absorb iron, an important nutrient for healthy growth and development. (⁴)
• Vitamin E: An important antioxidant that helps the body combat free radicals that can contribute to chronic diseases. (4)
• Zinc: Known for its antioxidant properties, zinc helps support the immune system by warding off bacteria and viruses. (⁵⁾ It’s also essential for wound healing. (5)
• Selenium: This mineral protects the body from free radicals and infections. (⁶)

Beta glucans: These fibers play a key role in regulating the immune system (7) and activating and strengthening immune cells.

Emergen-C Kidz Zero Sugar Daily Immune

Emergen-C Kidz Zero Sugar Daily Immune Support includes the following immune-supporting nutrients:

• Vitamin C
• Zinc
• Vitamin B6: An essential vitamin for producing cells for the immune system. (⁸⁾

While it has other important nutrients like vitamin B12 and biotin, their primary function doesn't directly support immunity. I also appreciate that it doesn't contain any added sugars, and is sweetened with stevia and allulose, a low-calorie natural sweetener.

Formula Winner: Hiya Kids Daily Immune

Criteria #2: Ingredient safety

I’m super picky about ingredient safety because I want to make sure what I’m giving my kids is safe. 

Hiya Kids Daily Immune

I appreciate that Hiya conducts third-party testing on every batch of their vitamins to ensure purity and quality to ensure they’re free from heavy metals and microbes. Each batch is certified by independent labs to meet strict federal and state safety standards, including compliance with California’s Prop 65. Hiya’s manufacturing facilities are also FDA-registered and GMP-certified, so I feel confident that their supplements are held to the highest quality and safety standards.

 Hiya’s Kids Daily Immune is free of:

• Synthetic dyes
• Gummy additives
• Added sugars
• Gluten
• Dairy
• GMOs

Emergen-C Kidz Zero Sugar Daily Immune

Emergen-C Kidz Zero Sugar Daily Immune Support is NSF certified, which means it meets strict standards and procedures, including thorough testing and material analyses. Emergen-C products are not third-party tested. It’s also free from:

• Gluten
• FD&C dyes
• Caffeine.

Ingredient Safety Winner: Hiya Kids Daily Immune

Criteria #3: Taste

Hiya Kids Daily Immune

They taste amazing—they’re fruity and sweet even without the added sugars!

Emergen-C Kidz Zero Sugar Daily Immune

They come in a sour and fruity flavor, which some kids might find fun and tasty, but not every child enjoys that puckered tart taste.

Taste Winner: Tied

Criteria #4: Cost

Hiya Kids Daily Immune

$35 per bottle containing 30 doses, or $1.17/dose

Emergen-C Kidz Zero Sugar Daily Immune

$14.99 per bottle containing 12 doses, or $1.25/dose
