Overview
The Tanita BF 680W is a digital body composition monitor with an LCD display, not a vitamin or supplement, that reads body fat alongside weight up to a 400 lb capacity. It appears here under a Vitamins & Supplements category page but functions as a bathroom scale style device.
This is a hardware device rather than an ingestible supplement, despite showing up in a supplements category listing. Digital body composition monitors like this use a bioelectrical signal through the feet to estimate body fat percentage in addition to standard weight, giving a household a second data point beyond the number on the scale.

Who it's for
Fits households wanting one digital scale that reports body fat percentage as well as weight, with capacity up to 400 lb. Not a fit for anyone actually looking for a supplement, despite the category placement.
Pros and cons
- Reads body fat percentage, not just weight
- 400 lb weight capacity
- Digital LCD display
- Miscategorized here as a supplement rather than a scale
- Bioelectrical body fat readings vary with hydration
Performance notes
Body fat readings on scales like this come from a low electrical signal sent through the feet, which is why the special feature is listed as body fat measurement rather than weight alone. The LCD display shows the digital readout, and the 400 lb weight capacity sets the upper limit for accurate use.
