Global snack bar market hits $32.66 billion projection

According to new data from Mordor Intelligence released on September 8, 2026, the global snack bars market size is projected to grow from $21.94 billion in 2026 to $32.66 billion by 2031. This growth is driven significantly by "protein reformulation," where manufacturers are increasingly fortifying standard snacks with higher protein content to meet mainstream demand rather than just athlete-specific needs. The market's trajectory highlights a shift where protein is no longer niche but a primary driver of consumer choice in the broader food sector.

FDA warns on supplements with undeclared anabolic steroids

In enforcement actions highlighted over the past week, US Imports reported that the FDA has issued warnings for five supplements that triggered alerts in 2026 due to labeling violations and safety issues. One specific product was found to contain anabolic steroids—a controlled substance—that appeared nowhere on the label, leading to adverse event reports of liver damage. These cases underscore the ongoing challenge regulators face in policing the dietary supplement market, where contamination with banned substances remains a critical risk for consumers and athletes alike.

New Zealand tribunal rules on intercepted supplement parcel

The Sports Tribunal of New Zealand recently published a ruling concerning an athlete involved in a case where a parcel containing Methandienone (Dianabol), an anabolic agent, was intercepted by New Zealand Customs. The tribunal addressed the possession and attempted use of the prohibited substance, which was found within supplement packaging. This case serves as a recent reminder of how strict liability principles apply even when substances are hidden within commercial supplement products, reinforcing the need for rigorous third-party testing by athletes.

Local view

German consumer press continues to scrutinize protein bar quality and creatine efficacy. General-Anzeiger (GA) reported on Ökotest findings where two protein bars were rated "insufficient" (ungenügend) out of twenty tested, citing misleading claims about sugar content and protein quality. Meanwhile, F.A.Z. Kaufkompass highlighted ESN Designer Protein Bar as a top performer in their September 2026 test, noting it contains a substantial amount of protein with low sugar, reflecting the German market's high sensitivity to nutritional transparency.
