https://www.indiegogo.com/projects/vita ... tal-advice#/What the product claims to do is measure vitamin and mineral levels non-invasively by simply touching a small probe against a specific location on the skin. I was immediately skeptical of these claims – how can the blood level of vitamin B12, for example, be measured on the skin? Further, the probe just has a simple electrical conductor. At best it is measuring skin conductance, which can be used to measure sweat levels but not much else.
http://theness.com/neurologicablog/inde ... #more-8604Vitastiq makes extraordinary medical claims without the slightest bit of plausibility or evidence. The only way to characterize such a device, in my opinion, is as medical quackery. Anyone relying upon this device to monitor their health and make decisions about diet and supplements is at risk.
