Hi @kanetuck, I agree that we shouldn’t need supplements in a perfect world. Unfortunately, the world is not perfect, the lives we live are not perfect, our genetics are not perfect, and the upbringing and nutrients we received while we were growing were not perfect. All of these things contribute to what we may need to add to our diets on an individual basis.
I stopped eating dairy products quite some time ago because I realized it was causing skin and joint issues. Since all the “experts” talk about how important dairy is for healthy bones, I supplemented with something called Citrical (calcium citrate and vitamin D) for years. I was still having back problems and recently stopped the calcium supplements, although I did add in some vitamin K2. Within a few days, my back was greatly improved. Why? Well, I wonder if I had excess Ca settling in my joints from the supplements and the combination of stopping the excess Ca and the vitamin K helped pull the calcium into my bones? 
So, here was an example where it turns out the supplement may have been doing harm. I mean, it was Ca. We all need calcium, right? I have to admit, I may not have ever thought of the Ca causing harm, except for a thread on this forum about just that.
Magnesium on the other hand, seems to be something I have to take in largish quantities. I have even tried lowering the dosage and quitting it several times, but my symptoms of magnesium deficiency return fairly quickly. Why do I need large doses of Mg? I don’t know. Genetics? Diet as a growing child?
I do take vitamin D3 and K2 along with magnesium. I work in an office with no windows 
for forty hours a week, so…
Finally, electrolytes. They have been my bane on low carb. Not enough salt causes me to get aches and cramps. I have also tried stopping extra salt supplementation, but to no avail.
So, I guess my story boils down to: I would love not having to add supplements to my diet. I’ve tried not adding supplements to my diet, but my lifestyle, genetics, and who knows what else, seems to say otherwise.
I will add that it is easy to fall into the trap of trying supplements. Many of us want to find that magic pill that will solve health problems be it medication, vitamins, or some kind of herbal supplement.
I think in this day and age, with plants and animals genetically modified or bred to grow as quickly and big as possible, the amount of nutrients per calorie of food has gone way down. Someone my age and size, 56 year old female, 63 inches tall, for example, would probably have to eat way more than her body needs calorically to get everything it needs nutritionally.
but we can follow our path to get there wtih learning us thru eating changes.
, definitely missed that.
