Weathered Shell Calcium is a weathered shell fossil of Kamionishi shellfish excavated from the stratum 15 to 20 million years ago in the Kuromatsu Fault in the Yakumo region of Hokkaido. Calcium SIMA powder is made by turning this weathered shellfish fossil into powder. Calcium from fossilized fossilized shellfish is an ideal inactive calcium that can be efficiently ingested into the body, which tends to be insufficient from food alone.
Also, unlike active calcium, inactive calcium has the ability to maintain a constant blood calcium concentration, so there is no need to worry about symptoms such as calcium paradox. Weathered shell calcium is recognized by bone specialists as it reaches the bones!
