i don't have hypothyroidism. my thyroid levels like free t3 etc were tested during the diagnostic process and came back all right. not sure what end of the ranges i was in so i might dig out those results and have a look.
zinc nutrition is important for optimal thyroid function.
research shows zinc deficiency is associated with constipation, loss of libido, tinnitus, eyesight, hair loss, and skin issues.
ms patients tend to have zinc levels in the low end of the normal range. healthy controls have average levels in the high end of the normal range (around 18 umol/L).
here's a study comparing thyroid hormones and high and low zinc levels in apparently healthy controls:
Effect of Zinc on Some Biochemical Indices of Metabolism
Riitta Hartoma, E.A. Sotaniemi, J. Määttänen
The role of zinc in some metabolic functions in man was investigated in 14 healthy male volunteers with primarily high or low serum zinc
. In all the subjects, results of laboratory tests reflecting
blood picture, metabolism of carbohydrates, fats and proteins and thyroid function
as well as serum calcium and phosphate levels varied within the normal range
. Significant differences between the subjects classified by serum zinc were found in α1-globulins. Serum thyroxine [JL edit: thyroxine is T4]
, effective thyroxine ratio and the immunoglobulins IgA showed a tendency to lower levels in subjects with low serum zinc
. Substitution with zinc sulphate resulted in an increase of
α1 -globulins, serum thyroxine
and effective thyroxine ratio, and a decrease of albumin. Other tests remained unchanged by the therapy. The results suggest that there is a relationship between zinc and some metabolic functions in healthy subjects without symptoms of zinc deficiency.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
