Human free radicals occupy too much cell space, which makes cells lose their normal metabolic function and life activity function. The negative ions released by tourmaline material can effectively scavenge free radicals, make them nontoxic, enhance the secretion function of gastric juice and strengthen the digestion and absorption function of intestinal tract.

The tourmaline energy cup can inhibit bacteria. The antibacterial rate of silver ions in tourmaline cup to pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus is over 95%, which effectively kills harmful bacteria, keeps the water safe and clean, and establishes a defense barrier for human body.

Improve human immunity. The activated water of tourmaline can accelerate microvascular circulation, promote metabolism, improve physical fitness, improve human immunity and eliminate fatigue.
