Imbalances will cause either overactivity which can result in stress or underactivity, which can result in low energy levels and insufficiency. Calcium and postassium regulate the activity of the thyroid gland. If the ratio between them and the mineral levels is normal, the thyroid functions at maximum energy levels.
  Calcium slows down the activity of the thyroid and potassium speeds it up. If the level of calcium is too high, the energy level of the thyroid will be slowed down. If the level of potassium is too high, the thyroid will be overactive and will eventually wear out completely because of too much stress.
Why Dairy Products Are a Poor Source of Calcium
1) Dairy products are high in protein which increases calcium excretion from the bones and body.

2) Dairy products are high in phosphorus which inhibits calcium absorption.

3) Dairy products are very low in magnesium which is needed for bone to use the calcium which is absorbed.

4) Dairy products may contain saturated fat which makes calcium absorption more difficult.
We all can benefit from an absorbable calcium/mineral formulation, especially those most vulnerable to bone loss; women during and past menopause, anyone with questionable diets or sedentary lifestyles and seniors (men included).

While osteoporosis is commonly associated with calcium deficiencies, there are actually more than 150 diseases scientifically documented to be related to calcium deficiency. Prevention is the most economical way to approach this, as well as almost all other health problems. Following are some of the major deficiency problems:

Osteoporosis, high blood pressure, pregnancy-related high blood pressure, insomnia, colon cancer, breast cancer, menstrual cramps, muscles cramps, and restless-leg syndrome.

Calcium is used for much more in the body. It's also dissloved in the fluids in the body, those inside cells and those that bathe cells. There, it helps muscles spring into action and aids proper blood clotting. It assists nerves in transmitting impulses and helps launch hormones and enzymes on their journeys to inner organs.

Serum Calcium Levels Closely Guarded

Calcium levels in the blood rarely vary more than 5% above or below normal concentrations. When calcium levels fall below this, parathormone (produced by the parathyroid glands) act upon the body to replenish calcium levels in the blood. If calcium levels in the blood become too high, calcitonin (produced by the thyroid) lowers it. The active form of Vitamin D-3 (Chlolecalciferol), acting like a hormone, also regulates calcium levels in the blood.
