I hv been using silica for many years. Just recently while browsing came across Keiso soluble Silica made from rice husk. I bot two bottles as I read this Silica is highly absorb and safer for the body with a higher ppm 10 000. Thankyou Beauty and Health Senka for developing this Silica. I will certainly continue to drink this Silica. Been told I look 15 years younger than my age 😊
