1: Color, the real chelated calcium is pure white. Fake chelated calcium will be yellowish.
2: Particle size, our products are very fine, can be evenly spreaded to the skin, and can be directly absorbed by the skin, while the imitation chelated calcium will not be absorbed by the skin.
3: Dissolve in the water. The real chelated calcium will be completely dissolved in water (about 30 seconds), no deposition,no impurities. Imitation chelated calcium will not dissolve or dissolve very slowly, will be deposited at the bottom of the cup, the water is not transparent and has impurities.
4: PH. We can use PH test paper or phenolphthalein. PH is 7 for true chelated calcium, neutral. The water will not change color when you add phenolphthalein into the water. PH >7 for imitation chelated, drop the phenolphthalein reagent, the water become pink or red.
