We're not aware of PHITEN products having harmful effects on children or pregnant women. We do recommend keeping certain PHITEN products with small parts away from children as it may be a choking hazard. PHITEN is a health and wellness product designed for consumers. However, we always recommend consulting your physician regarding any health-related questions.

The Titanium Discs can easily be placed directly on specific parts of the body, whereas the Titanium Tapes can cover greater areas and be easily applied to your knees, elbows or other joints. For the sake of good hygiene, we recommend replacing the tape after prolonged use or after a period of heavy perspiration.

Yes. We recommend hand-washing them occasionally with soap or diluted laundry detergent and leaving them out to air-dry. If this is not enough, you can try using laundry stain remover; follow application directions and hand wash afterward. Do not use bleach (even for white necklaces/bracelets) as this may affect the color. Washing the products excessively may speed up the wear and tear of the material.

Repeated wetting and drying of the fabric or the application of heat can accelerate the material's wear and tear. Also, if the necklace contains any metal parts, these can heat up and cause discomfort or burns.
