We have confirmed that "sai" does not contain platinum ion. (minimum limit of determination, LD:0.0021 ppm). We remove low molecular weight like ion substances from "sai" through ultrafiltration membranes.
Does drinking "sai" cause metal allergy?
Generally speaking, metal allergy is caused by ionized metals. Metals are ionized by body fluid like sweat and sputum and taken into the human body and absorbed into the system of the body. This is the mechanism of metal allergy. It is said that precious metals, platinum and gold, are used for ornaments due to their characteristic of not being ionized easily and that they don't usually show allergic reaction.

We have confirmed by observation under an electric microscope that platinum in "sai" is not ionized or oxidized and also we have confirmed by the metal allergy patch test that "sai" is safe to drink.

We suggest those who have experienced metal allergy or get allergy reaction after drinking "sai" should consult doctors.

Why does "sai" look black?
The color of a metal is fixed when it becomes particles and in colloidized condition. In case of gold, the color is from red to blueish purple. In case of silver, yellow. In case of platinum, black. Why does this phenomenon occur? Electrons around metal particles absorb light and the difference of colors depends on the length of absorbed light waves. Originally, the color of colloidized platinum looks brown, but in case of "sai", it looks black rather than brown due to the fact that "sai" contains highly condensed platinum particles.
