On April 3, 2026, the FDA warned consumers not to use Addall XR Shot and Addall XL capsules, products promoted for energy and focus, after FDA testing found they contain undeclared drug ingredients that are not permitted in dietary supplements and may pose serious health risks.

(See ConsumerLab’s B Vitamin Supplements Review for more information about energy drinks and shots, and see our Top Picks among B vitamin supplements.)

FDA analysis showed that Addall XR Shot (orange-flavored liquid) contains phenibut and undeclared 1,4-DMAA, while Addall XL capsules contain DMHA and undeclared 1,4-DMAA. DMHA and 1,4-DMAA are stimulants that can raise blood pressure and increase the risk of serious cardiovascular events such as shortness of breath, chest tightening, or a heart attack. Phenibut can cause neurological effects, including sedation, and loss of consciousness. It can be addictive and cause withdrawal symptoms, even after only a few uses, and can cause life-threatening adverse effects if taken in combination with other substances or medications.

Addall XR Shot and Addall XL capsules are distributed by ZMB Enterprises and were sold nationwide online and in retail locations such as gas stations and convenience stores. ZMB has recalled both products.

Consumers should stop using these products immediately and discard them. Consumers who have experienced symptoms associated with the use of these products should contact their health care provider.
