Natpro and hypothyroidism


Natpro UK recommends a natural solution to improve Thyroid function: 

  1. Natural Progesteron Natpro cream supplementation
  2. Vitamin D supplementation
  3. Iodine supplement suplementation
  4. Healthy diet for improved digestion of vitamins and nutrients and overal healthy body physiology.
  5. Exercise to improve circulation, oxigenation and metabolism of body tissues.

Progesterone, Estrogen and Hypothyroidism


Norman Shealy, M.D., Ph.D. in his Book Natural Progesterone Cream (Safe and Natural hormone replacement) writes:”Unopposed estrogen dominance can interfere with thyroid hormone activity and is a common cause of thyroid dysfunction. Commonly observed symptomes of hypothyroidism (underactive thyroid) include fatique, costipation, muscle weakness, memory loss, infertility, swelling of hands, feet, weakness, memory loss, infertility, swelling of hands, feet and eyelids, dry skin, intolerance to heat or cold, indigestion, menstrual disorders, sleep disorders, loss of hair, emotional instability, premenstrual syndrome, and weight gain.

Estrogen and thyroid are two hormones that have many opposing actions, probably at the thyroid hormone-receptor level. Unopposed estrogen will prevent the thyroid from performing its normal activities and can lead to relative hypothyroidism despite normal blood levels of thyroid hormone. Progesterone, being a normal counterbalance to estrogen, inhibits many of estrogen’s undesirable effects, including its interference with thyroid hormone activity. I strongly suspect that a majority of women with mild hypothyroidism would be better treated with progesterone than using thyroid replacement therapy. when there is estrogen dominance, there is also a decrease of libido with mood swings and irritability, depression, and headache, all symptomes of hypothyroidism. natural progesterone is the source of kibido or sex drive in women and markedly increases kibido in men”.

Iodine deficiency and Hypothyroidism

In the same book, Norman Shealy writes: “Another contributer to hypothyroidism is iodine deficiency. Over eighty-five years ago, we thought we had solved the problem of widespread iodine deficiency by adding iodine to salt. unfortunately, for the past fifty years physicians have recommended minimized salt intake. During this same time the entire world has suffered a marked increase in nuclear radiation; ironically, it is the thyroid gland that is the most sensitive organ to radiation damage.

Finally we have been advised to increase our intake of cabbage, broccolli, and cauliflower (the brassica family) for their protective efforts upon the colon. But all these foods block thyroid use of iodine to make thyroid hormone. Ninety percent of individuals we see have low body temperatures, a prime feature of hypothyroidism. Iodine replacement restores normal body temperature. Thus, individuals with low body temperatures may suffer even more because of either estrogen dominance or progesterone deficiency or both.

For those with low body temperatures we recommend iodine supplementation of 1.0 mg per day for six weeks. If body temperature comes up to normal (97.6 F in AM and 98.6 in PM taken orally0), then continue with just 300 to 400 micrograms per day”.

Vitamin D deficiency and Hypothyroidism

Dr. Theodore Friedman, a noted thyroid expert and endocrinologist, published a paper entitled Vitamin D and Thyroid Disease. In this paper, Dr. Friedman summarizes over 20 years of studies pointing to low vitamin D levels in thyroid patients, particularly hypothyroid patients. Vitamin D interacts with the body’s complex biochemistry to help or hinder thyroid production. Patients may have a potential genetic condition in which their intestines are unable to absorb vitamin D, or perhaps their bodies cannot use vitamin D properly. The result is that the body has too little vitamin D at its disposal, even if the patient is taking in the RDA for the vitamin.

Other studies support Dr. Friedman’s assertions. The U.S. National Library of Medicine lists a paper on vitamin D and thyroid hormones that also suggests the possible complex interaction between this essential vitamin and the thyroid gland. Too little circulating vitamin D may hinder the body’s ability to produce and regulate thyroid hormones.
