Nutrition Certifications- AASDN AFPA ISSA

[BlueJayMuscle]

I am currently only ACE certified as a personal trainer and plan to get NSCA certified but I want to complete my certifications with a nutrition cert.

The ones that have most stuck out in my search are AASN, AFPA, and ISSA. Does anyone have any of these? Any info on the exams?

Any other respectable associations you know of?

Thanks in advance
