RE: [_Chat] is anyone on here on growth hormone?

As this is relevant to the main thyroid forum, I have moved it from the

Chat group here.

Zinc: An essential trace

mineral. The functions of zinc are enzymatic. There are over 70 metalloenzymes

known to require zinc for their functions. The main biochemicals in which zinc

has been found to be necessary include: enzymes and enzymatic function, protein

synthesis and carbohydrate metabolism. Zinc is a constituent of insulin and

male reproductive fluid. Zinc is necessary for the proper metabolism of

alcohol, to get rid of the lactic acid that builds up in working muscles and to

transfer it to the lungs. Zinc is involved in the health of the immune system,

assists vitamin A utilization and is involved in the formation of bone and

teeth.

Hypo-and

hyperzincemia has been reported to cause alterations in the adrenal secretion.

To determine the acute effect of zinc on cortisol levels, we studied 27 normal

individuals of both sexes aged 20–27 y after a 12-h fast. The tests were

initiated at 7:00am when an

antecubital vein was punctured and a device for infusion was installed and

maintained with physiological saline. Zinc was administered orally at 8:00am. Subjects were divided into an

experimental group of 13 individuals who received doses of 25, 37.5, and 50 mg

of zinc and a control group of 14 individual who received 20 mL of

physiological saline. Serial blood samples were collected over a period of 240

min after basal samples (−30 and 0 min). We detected an acute inhibitory effect

of zinc on cortisol secretion during 240 min of the study period in the

experimental group.

Abstract

Circadian

variations of zinc and cortisol concentrations in plasma were studied in six

healthy adult men. Three of them were tested over two different 24-h periods.

Results were analyzed by computerizing a best-fit curve for each 24-h profile.

Plasma zinc displayed a morning peak between 8.00 and 9.00 a.m. followed by an

almost linear decline throughout the day with lowest values observed shortly

before 6.00 p.m. A transitory increase occurred between 6.00 p.m. and 8.00 p.m.

followed by a slow decrease reaching its nadir around midnight. Thereafter zinc

increased steadily until 8.00 a.m. A similar profile was observed in a seventh

subject who was undergoing therapeutic starvation for obesity (fifth day of the

starvation period). In all subjects the time course of plasma cortisol fluctuations

paralleled that of zinc. Our results confirm the existence of a circadian

rhythm in plasma zinc independent of zinc intake and temporally related to the

circadian rhythm of cortisol.

Sorry forgot to add - that low zinc can cause low growth

hormone - Vitamin A and zinc are linked - low A then low zinc - and A and D are

linked.

You may some issues with low minerals and vitamins etc. so I would

sort these out first - the liver is where the GH is converted and zinc is

involved heavily in the liver.

If you drink then try to avoid all alcohol to prevent the liver

being overloaded when it has so much to do converting everything else you need

at the moment.

My issues were also Vit A and zinc related.

best wishes
