Includes information vitamin, minerals, elements and cellular / intracellular attributes and interactions, optimal levels of intake by age and certain conditions:
Calcium and Magnesium
The information presented is based on Cellular trace mineral analysis - not Serum / Blood measurements.
RDA / DRI, synergists, antagonists, side effects, and additional deficiency / overdose / toxicity symptoms are listed on Page 2.
Both elements share left / right-sided cell receptors and are essential to human health. Calcium (Ca) and
Magnesium (Mg) have become the "Gold Standard" when discussing nutritional supplements, mineral ratios,
paired cell receptors, or many nutrition-related health issues in general. [For detailed information on the
best Calcium to Magnesium Ratio see: "Mineral Ratios for Calcium, Magnesium and other Elements"].
Calcium is now the most promoted nutrient by proponents of conventional, nutritional, as well as alternative
medicine - yet at the same time, the assumed need is based purely on the speculation that the body's dietary
calcium intake is well below its requirements.
Of the approximately 1,000 g of calcium in the average 70 kg adult body, almost 98% is found in bone, 1% in
teeth, and the rest is found in blood, extracellular fluids, and within cells where it is a co-factor for a number
of enzymes. Calcium promotes blood clotting by activating the protein fibrin, and along with magnesium
helps to regulate the heart beat, muscle tone, muscle contraction and nerve conduction.
Parathyroid hormone (PHT) secreted by the parathyroid gland and calcitonin secreted by the thyroid gland
maintain serum calcium levels at a range of between 8.5 to 10.5, whereby calcium is mobilized from bone
reserves, and intestinal absorption of calcium is increased as needed. The parathormone can also affect
renal functions to retain more calcium. When blood calcium does up from too much parathyroid activity,
calcitonin reduces availability of calcium from bone.
The calcium to phosphorus ratio in bone is about 2.5 :1, while the ideal dietary phosphorus / calcium ratio
is estimated to be about 1 :1. Many dietary factors reduce calcium uptake, such as foods high in oxalic acid
(spinach, rhubarb, beets, chocolate), which can interfere with calcium absorption by forming insoluble salts in
the gut. Phytic acid, or phytates found in whole grain products, fiber-rich foods, excess caffeine from coffee,
colas, tea..., as well as certain medications may all reduce the absorption of calcium and other minerals, or
leach calcium from bone. Normal intake of protein, fats, and acidic foods help calcium absorption, however
high levels of these same sources increase calcium loss.
Chronic calcium deficiency is associated with some forms of hypertension, prostate and colorectal cancer,
some types of kidney stones, miscarriage, birth (heart) defects in children when the mother is deficient in
calcium during pregnancy, menstrual and premenstrual problems, various bone, joint and periodontal diseases,
sleep disturbances, mental health / depressive disorders, cardiovascular and/or hemorrhagic diseases, and
others (listed on Page 2).
Elevated calcium levels are associated with arthritic / joint and vascular degeneration, calcification of
soft tissue, hypertension and stroke, an increase in VLDL triglycerides, gastrointestinal disturbances, mood
and depressive disorders, chronic fatigue, increased alkalinity, and general mineral imbalances. High calcium
levels interfere with Vitamin D and subsequently inhibit the vitamin's cancer-protective effect unless extra
amounts of Vitamin D are supplemented.
For best absorption, calcium supplements should be taken with food, and doses should not exceed 500 mg at a time.
