Magnesium, Calcium and Potassium – Supplementation
Click here for High Potassium Foods
Lilian put this source of data up, a couple of years ago.
the general advice is to take your thyroid meds away from foods high in calcium but as you can see, that also includes quite a lot of magnesium
of the two or more reasons to avoid high intake of calcium at the same time as your thyroid meds, the ‘binding’ of the thyroxine to calcium ‘salts’ would prevent absorbtion; in some respects magnesium ought not to be quite so bad as calcium, but it will be included with many foods ~ also high in calcium.
Hence, the best advice is to avoid food(s) at the same times as your thyroxine ( and/or NDT ).
Leslie’s Home Lab Experiment was carried out some five or more years ago and she was well able to tolerate thyroid meds at night ( thyroxine or NDT ).
Dutch workers repeated this experiment on a small scale, a year or so back and recommended the addition of T3 ( slow release ) at night time to mimic the circadian rhythm of TSH/T4/T3 release overnight.
This would obviate the problem of food in the morning, too close to thyroid meds.
I managed to find a source of light magnesium carbonate to add to acidic drinks so that I could expect to absorb more ‘soluble’ magnesium when I did decide I needed to add some extra magnesium to my ‘diet’.
A while back, it was estimated that about half of people with adverse cardiac events showed no signs of atherosclerosis at post mortem.
Hypothyroid folk tend to loose magnesium from their ‘hypoxic’ cells, whilst hyperthyroid people tend to need more to cope with the enhanced metabolism required in cells that are ‘overstimulated’.
During the transition from hypo- to hyperthyroidism, there is a point of quite high danger when the cells start to ‘demand’ far more magnesium than is easily available from the blood stream.
Both potassium and magnesium are needed at that point to readjust the cell content of electrolytes in favour of higher a metabolic rate ( more potassium and magnesium and less sodium ).
