The parathyroid glands sit behind the thyroid and release parathyroid hormone (PTH). PTH raises blood calcium by absorbing bone, increasing gut absorption, and holding calcium in the kidney. It is a stress signal when dietary calcium or magnesium is low or when energy fails.

Calcium and magnesium

[edit]

Low calcium or magnesium intake stimulates PTH. Chronic high PTH pulls calcium from bone into soft tissues under poor energy conditions. Milk and fruit, or milk and meat, supply calcium and magnesium together and quiet that axis.[1]

See Calcium, Magnesium, Milk, Vitamin D.

Practice

[edit]

Food calcium and magnesium first. Fix thyroid oxidation so calcium stays in bone.

High PTH with low dietary calcium is a common modern pattern under seed-oil, low-dairy diets. See Calcium, Hypothyroidism, Stress.
