Pittsburg, Kansas | We take some threonate on and off.
An interesting question is, why do we need these minerals or supplements when my parents and grandparents never took them?
I think there might be good reasons.
When I was a child and till about 30 years old I drank water from a shallow, farm, hand dug well. Fifteen feet from the surface to the top of water. It was hard water. Not terribly high in iron but enough that in a week the stool needed cleaned or it would get a red shade. And definitely high in calcium. If you had a tiny seep in a steel pipe joint in a week it would seal itself off with calcium accumulated around the joint.
Eventually we went on rural water line. It also was hard water but from a deep municipal well.
We got minerals from the water we drank and the vegetables we ate out of the garden.
Then we put in a reverse osmosis system for our drinking water and ice from the refrigerator. We almost never drink well water directly any more. Maybe some in cooking, but even then often the water comes from the reverse osmosis faucet.
Reverse osmosis removes nearly all the minerals. In fact so much so that in our espresso machine we add back in about 1/4 tap water so the universal solvent water does not erode the copper components in the boiler and lines. In our deep dive into coffee making we found out a certain level of hardness is desired both for extraction purposes and for equipment life (too little hardness is not optimal and too much is also bad).
A number of on line doctors claim that a lot of people are deficent in both magnesium and potassium. Some also claim the commercial vegetables we eat from the grocery store have a lot lower amount of minerals than they once historically had. I don't know if this is true or not. But the change in water drinking habits I'm convinced is a contributing factor to mineral deficiency.
We also occasionally will use LMNT brand electrolytes mix in our drinking water. Not all the time, but we do keep it on hand. We do the unflavored version.
Another tidbit of information. Don't count on blood tests for adequate minerals. The blood levels for some minerals are regulated very tightly. Too little or too much and you are either sick or die. So the brain will tell the body to rob minerals from bone and organs to maintain proper blood levels. So just because the blood test shows ok levels doesn't mean the level in the bone or organs are optimal.
My opinion based on what I think I've learned. It could be and often is wrong. Do your own research.
