InBody 970S vs Nutriguard-MS
InBody 970S and Nutriguard-MS: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 970S: when to consider it
For a comprehensive consultation when you want to follow water distribution and phase angles alongside fat and muscle. This newer 970 generation offers detailed outputs for clinical, nutrition, sports and research settings.
Nutriguard-MS: when to consider it
Nutriguard-MS measures bioelectrical impedance at 5, 50 and 100 kHz. Standard testing uses four adhesive electrodes on the hand and foot of one side. Body-composition and water estimates are evaluated from resistance and reactance using the relevant software; regional mode requires the appropriate procedure.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
