FDA Issues Warning Letters to Supplement Companies Using DMHA

Is this the death of the popular supplement ingredient DMHA? Well, if you are familiar with the workings of the FDA, it appears DMHA’s time is about over. The FDA recently issued 9 warning letters to different supplement companies that have been using DMHA in their products.

Ingredient suppliers have tried to stay one step ahead of the FDA by labeling DMHA by different names. Here is the list of the known aliases of DMHA, however, there could be more.

  • 2-amino-5-methylheptane
  • 2-amino-6-methylheptane
  • 1,5-Dimethylhexylamine
  • 1,5-DMHA
  • 2-aminoisoheptane
  • 6-Amino-2-methylheptane
  • 2-Heptylamine, 6-methy
  • 2-Isooctyl amine
  • 2-Metil-6-amino-eptano
  • Octodrine
  • Amidrine
  • Vaporpac


Once a company receives a warning letter, they have 15 business days from the date of receipt to notify the FDA of the specific steps they intend to take to make their products compliant with the law.

DMHA first became popular after the FDA made the popular weight loss and pre-workout ingredient 1,3 DMAA (OxyELITE Pro and Jack3d) illegal. The FDA argued that 1,3 DMAA was synthetic and thus mislabeled as a dietary ingredient. DMHA has been reported to give people similar effects to 1,3 DMAA, such as improvements in energy and focus.

Several supplement companies thought it was only a matter of time before the FDA sent warning letters pertaining to the use of DMHA as a dietary ingredient, and have already adjusted their existing formulas. While receiving a warning letter isn’t the nail in the coffin for a supplement ingredient, it’s just the beginning. If you are a fan of DMHA, you probably won’t have access to this ingredient much longer.
