Meta Labs Pharmaceuticals, LLC
FDA issued a warning letter to Meta Labs Pharmaceuticals, LLC (Roswell, GA) following a December 2025 facility inspection and April 2026 website review, finding that six products — Diabetic Advantage, Yacon Root Extract, Nattokinase Max, Viral Immune Booster, Arthritis Bursitis Rheumatism, and Respiratory Response — bore disease-treatment and cure claims that rendered them unapproved new drugs under the FD&C Act. The products were also found misbranded for lacking adequate directions for use, and two products (Diabetic Advantage and Respiratory Response) were adulterated due to serious CGMP violations including absent finished-product specifications, missing component identity testing, and incomplete master manufacturing and batch production records. FDA demanded a written corrective-action response within 15 working days and warned that failure to comply may result in seizure or injunction.
