HAIR ANALYSIS FOR THYROID ASSESSMENT by Dr. Wilson Hair analysis is excellent to help assess thyroid difficulties. It can indicate imbalances in many steps involved in thyroid hormone metabolism: PRIMARY HYPERTHYROIDISM In these cases, which are less common than secondary hyperthyroidism, the hair mineral analysis will reveal a fast oxidation rate. That is, calcium is often less than 40 mg% or 400 ppm and magnesium less than 6 mg% or 60 ppm. Sodium and potassium are often high if the hair is not washed at the laboratory. The thyroid is overactive, usually due to the presence of toxic metals such as mercury in the thyroid or pituitary glands or other toxic metals such as copper, lead, iron, cadmium or others. Metabolic balancing is usually very effective at restoring normal thyroid activity. SECONDARY HYPERTHYROIDISM This is the most common type of hyperthyroidism in my experience. Serum levels of T3 and T4 are often elevated. TSH may be high, normal or low. The patient will have symptoms of hyperthyroidism such as anxiety and exothalmos. Yet the patient is often fatigued as well. The hair analysis will show a slow oxidizer pattern, often with very low sodium and potassium levels and quite an elevated calcium level.
PRIMARY HYPOTHYROIDISM A hair calcium above 50 mg% and magnesium above about 9 mg% indicate some degree of biounavailable calcium and magnesium. This occurs mainly in slow metabolizers. One is often fatigued and may have other symptoms of low thyroid activity such as dry skin and hair, weight gain (though in some cases one is very thin), cold intolerance and others. If serum hormone levels are normal or elevated, physicians may not give thyroid support when it is in fact needed. WHEN THYROID HORMONE IS HARMFUL When hair tissue calcium and magnesium are low, as in fast metabolizers, cell membranes are more permeable. This causes more rapid uptake of thyroid hormone into the cells and an increased thyroid effect. The patient may present with fatigue or other symptoms suggestive of low thyroid activity. Serum thyroid hormone levels may be low normal or even decreased. A physician who only measures serum hormone levels (T3 and T4) or TSH might conclude that the patient needs thyroid hormone. This will make the patient's condition much worse, although it may provide a temporary energy boost. * The hair calcium level is an approximate thyroid effect indicator because thyroid hormone lowers calcium in the body. The higher the level of hair calcium, in general, the lower the effective activity of the thyroid gland. OTHER HAIR THYROID INDICATORS * The potassium level is associated with sensitivity of the tissues to thyroid hormone. Low hair potassium is associated with reduced sensitivity of the mitochondrial receptors to thyroid hormone. Even if circulating hormone levels are normal and hormones can be absorbed into the cells, when tissue potassium is low they may not be utilized, resulting in a low thyroid effect. This commonly contributes to thyroid problems in slow metabolizers. Potassium supplements rarely help because the problem is a loss of potassium due to kidney dysfunction and electrical imbalances at the cellular level. * Manganese deficiency can reduce thyroid activity. Manganese is required for T4 production. Manganese deficiency or biounavailability are very common today. Deficiency is associated with a hair manganese level less than 0.03 mg%. A level greater than 0.07 mg% often indicates biounavailability. Adrenal exhaustion causes manganese to become biounavailable as the binding protein, transmanganin, is not produced in sufficient quantity. * Metabolic typing can assess vitamin needs. Vitamins C and B-complex, for instance, tend to enhance thyroid activity. Higher doses are given to slow metabolizers and less to fast metabolizers to help balance thyroid activity. Supplementation without testing for the metabolic type is often ineffective or can aggravate thyroid imbalances. * Hair calcium and magnesium levels are associated with cell permeability. Biounavailable calcium and magnesium stabilize cell membranes. This causes reduced cell membrane permeability that decreases thyroid hormone uptake into the cells. This produces a cellular thyroid hormone deficiency. Serum hormone levels may be normal or even elevated. When the serum levels are elevated and the hair test shows a high calcium and low potassium, it is a secondary hyperthyroidism. * Copper is an important thyroid indicator. The key here is that one cannot use the hair copper level as the only copper indicator because copper often does not accumulate in the hair, but rather in the brain, liver and other organs. One must not supplement copper simply on the basis of the hair copper level. Other test numbers, however, offer excellent information about copper status: 1) Copper raises calcium and lowers potassium. Elevated calcium and low potassium is a slow metabolizer pattern associated with the presence of excess tissue copper. It does not matter if the hair copper is low, normal or high. The pattern is associated with reduced thyroid utilization and hypothyroidism. 2) Compensatory effects may occur. Copper stimulates the production of biogenic amines - epinephrine, norepinephrine and dopamine. These can cause anxiety, sweating and other symptoms similar to hyperthyroidism. The body may compensate for the inhibitory effect of high calcium and low potassium by increasing T3 and T4 to force more thyroid hormone into the cells. TSH may vary. The symptoms and blood tests cause some physicians to diagnose hyperthyroidism. Irradiation or even surgery may be recommended when the real problem is copper imbalance. This occurs commonly. 3) Weak adrenals cause copper to become biounavailable. This produces another mixed picture. Often this is indicated by a sodium/potassium ratio less than 2:1 or a hair copper less than 1.0 mg%. In these cases, even if hair copper is high, one must give some copper to relieve symptoms until copper becomes biologically available. 4) Fast metabolizers are copper deficient. They have a relatively low hair calcium level and elevated hair potassium. Their cells are excessively permeable and sensitive to thyroid hormone. Fast metabolizers all require copper supplements even if their hair copper level is normal or elevated. * Other Toxic Metals and Imbalances. Energy production requires many nutrients, and can be blocked by toxic chemicals and heavy metals. Hair analysis may provide indicators of an impaired energy such as cadmium toxicity or zinc deficiency that causes thyroid hormone to be ineffective in stimulating energy production. * Autonomic Balance. Most slow metabolizers have depleted their sympathetic nervous systems and are in a pathological parasympathetic state. This can affect thyroid hormone release.
