(Uses): Helps to regulate calcium metabolism and normal calcification of the bones in the body as well as influencing our utilization of phosphorus. Very important in children. Helpful in maintaining the nervous system, heart function, and for normal blood clotting- all which are affected by calcium levels.

(Deficiency): In children, the bone disorder is rickets.

Alfalfa, bladder, horsetail nettle, parsley.
(RDA): 400 IU’s per day. There is new research that these levels may be too low. According to the Vitamin D Council, “If you use suntan parlors once a week or if you live in Florida and sunbathe once a week, year-round, do nothing. However, if you have little UVB exposure, my advice is as follows: healthy children under the age of 2 years should take 1,000 IU per day—over the age of 2, 2,000 IU per day. Well adults and adolescents should take 5,000 IU per day”.
(Assimilation): Works best with adequate calcium and phosphorus.
