This product takes the purified edible seaweed iodine salt as the primary raw material, is added with the Calcium selenite reasonably, then is made up strictly according to the standard. The formula is scientific, the craft is advanced. It has characteristics of complementing calcium safely, convenient, fixed time, and fixed quota.
Calcium: the essential nutrition ingredient by human body life activity. The middle-aged person and old person are possible to have contracture or twitch on muscle if lacking the calcium. The calcium-lacking in child may cause rickets, skeleton abnormal, uneven tooth and so on.
(Ingredient): the purified edible seaweed iodine salt, Calcium selenite
