The hundreds of BioFit customer reviews and testimonials available both on the official website and elsewhere on the internet seem to corroborate the claims of the manufacturer. Even the few customers that I was able to personally interview confirmed the same, and with much enthusiasm.
Besides, the manufacturer offers a 180-day 100% money-back guarantee if you are not satisfied with the results. This suggests that they are quite confident about the supplement and its result. So the supplement must surely be legit. Also, to avoid scams and fake supplements, place your order through the official product website.
