On January 31, 2013, the FDA issued a warning letter to Liquid Health, Inc. following a facility inspection which found the company's dietary supplements, including Attention, Calcium and Magnesium, Diabetic Support, Immune Balance, and Ultra-Antioxidant to be adulterated because they were prepared, packed, or held under conditions that violate Current Good Manufacturing Practices for dietary supplements.

These violations include failure to conduct at least one appropriate test or examination to verify the identity of a component that is a dietary ingredient, failure to establish specifications for the identity, purity, strength, and composition of the finished batch of each dietary supplement and releasing for distribution dietary supplements that did not meet specifications on their labeling.

Liquid Health also failed to report a Serious Adverse Event Report within 15 days, after a consumer complained that Liquid Health Complete Multivitamin had a different taste and smell from the same previously purchased product. The consumer continued using the product and subsequently developed a bacterial infection requiring antibiotic treatment.

The FDA found the company's written responses regarding these violations to be inadequate.

Additionally, the FDA found statements made about Attention, Calcium and Magnesium, Diabetic Support, Immune Balance, and Ultra-Antioxidant on labels and Liquid Health's website to be drug claims.

Attention contains B vitamins, vitamin C, calcium, magnesium, chromium, choline, a blend of phospholipids and essential fatty acids, gamma-aminobutyric acid, taurine, L-tyrosine, extracts of banana, kiwi, mango, pineapple, cranberry, cherry, raspberry, red pepper, plum, apricot, ginger, broccoli, spinach, kale, cabbage, orange, grapefruit, lemon, lime, green tea, DMAE, red algae, stevia rebaudiana, grape seed extract, L-theanine and pumpkin seed extract.

It was promoted for the treatment of ADHD with statements such as "designed to supply nutrients thought to reduce symptoms of ADD/ADHD."
