......The world's first personal device for checking your vitamin and mineral status using a smartphone."

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.

Vitastiq 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.

This bit doesn't fill me with confidence...

So, what's the trick? There isn't one – just a synergy between traditional knowledge and modern technology. A thousand years of acupuncture knowledge proves that acupuncture points differ from the surrounding skin. In terms of electrical current, there is an increased conductance and decreased resistance at these points.
