Clif made their reputation with adult energy bars for athletes. The ZBar brings that approach to kids - but does the formula translate?
The Organic Foundation
Clif Kid ZBars carry USDA Organic certification, which means the ingredients meet federal organic standards. The base is organic oat flour, organic cane syrup, organic brown rice syrup, and organic oat fiber. You'll also find organic dates, organic soy flour, and organic flavors depending on variety.
The organic certification is meaningful. It means no synthetic pesticides on the oats, no GMO ingredients, and stricter processing standards. For families prioritizing organic, that label carries real weight.
The Vitamin Question
Clif promotes that ZBars contain 23 vitamins and minerals, including calcium, iron, zinc, and B vitamins. These are added (fortified), not naturally occurring from whole foods. Is that valuable?
My take: fortification is neither terrible nor ideal. It's better than nothing for picky eaters, but it's not the same as nutrients from real foods. If your kid eats varied whole foods, they probably don't need the fortification. If your kid lives on three foods, the added vitamins provide some insurance.
Nutritional Reality
Per bar (36g serving):
- Calories: 120
- Sugar: 10g
- Fiber: 2g
- Protein: 3g
That 10g sugar is my concern. Yes, it's from organic sources (organic cane syrup, organic brown rice syrup), but organic sugar is still sugar. The AAP recommendation is under 25g added sugar daily for kids - one ZBar takes 40% of that budget.
The protein (3g) and fiber (2g) provide modest nutritional value but won't keep hungry kids satisfied for long.
The Soy Factor
ZBars contain organic soy flour, which matters for two reasons:
-
Allergen: Soy is a top-8 allergen. Families avoiding soy (allergy or preference) should skip these.
-
Soy debate: Some parents prefer to limit soy for various reasons. If that's you, look elsewhere.
For families without soy concerns, organic soy flour is a reasonable protein source.
Taste and Texture Testing
My kids' verdict: "Good but not amazing." They'll eat them, but they don't request them. The texture is soft and chewy but noticeably processed - not the same as a homemade oat bar or the whole-food feel of Once Upon a Farm.
Flavor options include Chocolate Chip, Chocolate Brownie, Iced Oatmeal Cookie, Honey Graham, and Peanut Butter (which adds nut allergen concern). Chocolate varieties are the most popular in our house.
Value Calculation
At $8.49 for a 12-count box (~$0.71/bar), ZBars are mid-range pricing. Slightly more expensive than Nature's Bakery ($0.58) but less than RXBAR Kids ($1.25) or Once Upon a Farm ($1.75).
For 180 school days at $0.71/bar: $127.80 annually per kid. Reasonable but not budget-tier.
The Packaging Reality
Each bar is individually wrapped in non-recyclable packaging. Clif has made sustainability commitments, but the wrappers still end up in landfills. For environmentally conscious families, this is a consideration.
Comparing to Alternatives
vs. MadeGood ($0.72/bar): Similar price, but MadeGood is top-9 allergen-free (ZBars contain wheat and soy, possibly nuts). MadeGood wins for school safety.
vs. Nature's Bakery ($0.58/bar): Nature's Bakery is cheaper with similar sugar content. ZBar adds organic certification and fortification.
vs. RXBAR Kids ($1.25/bar): RXBAR has 7g protein vs. 3g, better for satiety. ZBar has organic certification RXBAR lacks.
Who Should Buy This
Families prioritizing USDA Organic certification. Parents who value added vitamins/minerals for picky eaters. Kids who enjoy soft, chewy bar textures.
Who Should Skip This
Families avoiding soy. Those seeking minimal-sugar options (10g is moderate, not low). Parents prioritizing allergen-free for school lunches. Anyone seeking high-protein sustaining snacks.
The Verdict
Clif Kid ZBars are a decent organic option but not exceptional. The USDA Organic certification and vitamin fortification are genuine positives. However, 10g sugar, soy content, and processed texture prevent them from reaching top-tier status. For organic-prioritizing families, these are fine. For those focused on minimal ingredients or allergen safety, better options exist.
