Kirkland Signature allulose lawsuits
The short answer
- One verified proposed class action challenges “Sugar-Free” claims on Kirkland Signature Hydration Electrolyte Drink Mix.
- Rule in play: 21 C.F.R. § 101.60(c)(1) (the sugar-free rule, which Franco addressed).
- None of these cases is in the Seventh Circuit, so Franco v. Chobani is persuasive authority only.
- No liability finding, class certification or court-approved settlement has been identified in the records reviewed as of October 3, 2026.

The rule in play
The federal rule treats “sugar free” and “no added sugar” claims under separate subsections. Claim families below come from our case record; they group reported allegations.
21 C.F.R. § 101.60(c)(1)
Sugar Free
Addressed in Franco: The sugar-free rule, § 101.60(c)(1), which Franco v. Chobani addressed.
Franco v. Chobani held that allulose falls within the federal definition of sugar for the regulation it interpreted. It did not decide liability, and its binding effect is limited to the Seventh Circuit.
