Calcium In Human Physiology
Calcium is essential for bones, teeth and nerves. The world’s largest human nutrition study indicated that vegetarian diets are a more effective source of Calcium. Need for supplementation has probably been exaggerated – Ignoring the need for Strontium and Silicon. Studies indicate that crude Calcium mineral supplements and dairy-form may actually interfere with assimilation of the plant-form of dietary Calcium.
Role of Calcium in Your Body
About 99% of our calcium is found in bone structures. However, calcium is essential for 4 other critical roles:
- Cell Membrane Regulation – affecting cell permeability, muscle contraction and nerve impulse conduction.
- Body Fluid Regulation – affecting blood clotting, acidity and alkalinity
- Regulation of cell division
- Regulation of hormone secretion – insulin
Function of Calcium
Circulatory – excites the heart, constricts small blood vessels
Excretory – inhibits water loss
Digestive – in excess, is constipating
Nervous – slows nerve impulse transmission
Reproductive – required for normal cell division
Endocrine – inhibits release of thyroid-releasing and other pituitary hormones
Blood – stimulates blood formation and is required for blood clotting
Muscular – reduces muscular irritability and contractibility
Skeletal – main component of bone
Metabolic – required for phosphorus metabolism and energy production in the Krebs cycle.
Detoxification – inhibits uptake of lead, antagonizes cadmium.
Cellular – decreases permeability of cells to sodium and potassium ions.
Calcium Deficiency Symptoms
Fast oxidation, muscle cramps and spasms, tooth decay, irritability, nervousness, anxiety, fight-flight reaction, insomnia, bruising, high blood pressure, osteoporosis, increased tendency to absorb lead and cadmium.
Symptoms Associated with a Calcium Excess
Slow oxidation, fatigue, apathy, depression-mental, withdrawal-social, kidney stones, gall stones, arthritis, hardening of arteries, constipation.
Nutrients that are Synergistic with Calcium
Absorption – vitamin A and D, stomach acidity, protein in diet.
Utilization – magnesium, copper, vitamin C
Absorption – fluoride, low stomach acidity, low protein in diet, phosphorus in excess.
Utilization – lead, cadmium, sodium, potassium, high protein diet increases calcium loss in urine.
Hair Analysis Notes
High calcium usually indicates that calcium is leaving the bones and accumulating in the soft tissues of the body. High calcium is associated with a slow oxidation rate and is a good indicator of hidden copper toxicity. High calcium on a retest often means the body is eliminating excess calcium.
Low calcium levels usually means calcium is being lost in the urine. Low calcium is also associated with a fast oxidation rate – alarm stage of stress. Low calcium is often associated with copper deficiency.
Reasons for Calcium Supplementation
To slow the oxidation rate, to help detoxify lead and cadmium, to balance key mineral ratios.
Seafood – sardines, caviar, smelt
Nuts/seeds – almonds, sesame seeds, filberts
Vegetables – kale, collards, mustard greens, turnip green, green vegetables, dandelion greens, soybeans, celery, broccoli
Miscellaneous – molasses, kelp, brewer’s yeast, torula yeast
Fruits – oranges, strawberries, raspberries, prunes,
Herbs – comfrey leaves, coltsfoot, chamomile, blackstrap molasses, figs, watercress, broccoli, olives.

The Effects of Calcium on Personality
Emotionally unstable, irritable, hyperkinetic behavior, nervous, short tempered, tense, unable to slow down, extroverted, lack of psychological buffering or defense mechanisms
Rigid, defensive, withdrawn, calcium shell, introverted, sluggish, numbed, tired
