Zarbee’s is a generally well-regarded brand, especially for parents looking for drug-free alternatives to traditional cough and cold products. Founded by pediatrician Dr. Zak Zarbock, the brand built its reputation on honey-based formulas free of alcohol, artificial flavors, and common cough suppressants. But “good” depends on what you’re buying and what you expect it to do. Some Zarbee’s products have solid evidence behind them, while others rest on thinner ground.
What Zarbee’s Actually Sells
Zarbee’s flagship product is a honey-based cough syrup for children, formulated with vitamin C and zinc. The line has since expanded to include adult cough syrups, children’s sleep aids containing melatonin, multivitamins, and immune support supplements. The brand is now owned by Kenvue, the consumer health company that split off from Johnson & Johnson in 2023, which gives it the distribution and manufacturing backing of a major corporation.
The core selling point across most products is what they leave out: no dextromethorphan (the standard cough suppressant in most OTC medicines), no alcohol, no artificial dyes, and no gluten. For parents who are wary of giving young children conventional cold medicines, that ingredient profile is the main draw.
The Case for Honey-Based Cough Syrups
This is where Zarbee’s has its strongest footing. Honey is not just a folk remedy. Research has shown that honey is better than store-bought cough syrups at reducing how often coughing happens and how severe it is at night, according to the American Academy of Pediatrics. The mechanism is straightforward: honey coats and soothes the throat, encourages healthy mucus production, and calms cough sensors in the throat and upper airways.
That’s a meaningfully different approach from dextromethorphan, the active ingredient in most conventional cough medicines. Dextromethorphan works in the brain by essentially turning off the cough reflex. The downside is that coughing exists for a reason. It clears mucus, irritants, and debris from the lungs. Suppressing that reflex can slow the body’s natural recovery process. Honey, by contrast, reduces the urge to cough by addressing the irritation itself rather than blocking the brain’s ability to respond to it.
One important caveat: honey-based products should never be given to children under one year old. Honey can cause infant botulism, a serious illness. Zarbee’s does label its honey products accordingly, and the AAP recommends honey only for children aged one and older, in doses of about half a teaspoon to one teaspoon as needed.
Where the Evidence Gets Weaker
Not everything in the Zarbee’s lineup has the same level of support. A Penn State study funded by Zarbee’s itself looked at the company’s agave nectar cough syrup (designed for children too young for honey) and found that both agave nectar and a grape-flavored water placebo performed better than no treatment at all. However, there was no significant difference between the agave and the placebo. In other words, the act of giving a child something sweet and soothing appeared to help, regardless of whether it was the actual product or flavored water.
That doesn’t mean the product is useless. A soothing liquid can genuinely comfort a coughing child, and the placebo effect in pediatric cough studies is consistently strong. But it does mean you shouldn’t expect the agave-based products to work through any special medicinal mechanism.
Children’s Sleep Aids Deserve Extra Scrutiny
Zarbee’s melatonin-based sleep products for kids are among their most popular items, and they deserve a more careful look. Melatonin is a hormone your body naturally produces to regulate sleep, and giving it as a supplement is not the same as giving a child a vitamin.
A study of 31 different melatonin supplements found that the actual dosage can vary widely from what’s listed on the label, sometimes containing significantly more or less melatonin than advertised. This is an industry-wide problem, not specific to Zarbee’s, but it’s worth knowing. Melatonin supplements are regulated as dietary supplements, not drugs, so they don’t undergo the same testing rigor as prescription medications.
Potential side effects in children include drowsiness (beyond the intended effect), headaches, increased bedwetting, irritability, nausea, and dizziness. The American Academy of Pediatrics considers short-term use relatively safe but says more research is needed on long-term effects, particularly regarding how supplemental melatonin might influence puberty. Melatonin is not recommended for children under three. Calls to poison control centers about melatonin overdoses in children increased by more than 500% between 2012 and 2021, largely because these products are marketed in gummy form and can be easy for kids to access.
If your child has occasional trouble sleeping, Zarbee’s melatonin gummies aren’t inherently dangerous for short-term use. But treating them as a nightly routine without understanding the limitations of supplement regulation is a risk many parents don’t realize they’re taking.
How It Compares to Other Brands
Zarbee’s occupies a specific niche: parents who want something on the shelf that feels like “doing something” for a sick child without resorting to conventional cough suppressants. In that niche, it’s one of the more recognizable and widely available options. The honey-based cough syrups are backed by legitimate evidence, the ingredient lists are transparent, and the backing of a major consumer health company (Kenvue) provides some manufacturing consistency.
Where Zarbee’s is less compelling is when you compare the cost to simply buying a jar of honey. For cough relief in children over one, the AAP recommends plain honey in small doses. A Zarbee’s cough syrup adds vitamin C and zinc to the formula, but neither of those ingredients has strong evidence for shortening a cold once symptoms have started. You’re paying a premium for the convenience of a measured dose in a child-friendly bottle, which has real value for some families but isn’t medically necessary.
The Bottom Line on Zarbee’s
Zarbee’s is a solid brand for its core product: honey-based cough syrups for children and adults. The honey mechanism is well-supported by research, and the drug-free approach avoids the downsides of conventional cough suppressants. For the sleep and supplement lines, the picture is more mixed. The products aren’t harmful when used as directed, but the evidence behind them is thinner, and the lack of strict supplement regulation means you’re placing more trust in the brand than you would with a pharmaceutical product. If you’re buying Zarbee’s cough syrup for a sick toddler, you’re making a reasonable, evidence-informed choice. If you’re buying melatonin gummies for nightly use, it’s worth understanding what you don’t yet know about long-term effects.
