Different nutritionists use different equipment. I am basing my choice of a nutritionist, based partly oponw what typpe of testing equiment they have in the office. Notritionists seem hesitant to send patients out for an EAV or MSA evaluation.
Currently, I am leaning toward the MSA equipment by Biomeridian. There were apparently some difficulties with some individuals in the company, but they have spent millions on researching thier results, and updating their evaluation software.
