Since magnesium and potassium information isn't required on food labels, you are most likely getting more than you think of those. If you look at the nutrition details in your tracker, you'll see that almost any packaged/branded food will show zero for both of those. That doesn't mean they don't have them; it just means the information field is empty in the database because the manufacturer doesn't have to provide that info. Calcium figures in your tracker are a little more reliable, but if you're deficient there, it's really better to add some higher-calcium foods than to take a supplement.
In general, with the exception of folic acid and a few other nutrients, supplements don't appear to be very helpful. There are quite a few long-term studies on supplementation that have been completed recently, and they pretty universally show that people who take supplements aren't any healthier than those who don't, assuming their diets are similar. Evidently, it may not be the potassium or magnesium itself that's good for you, but rather the magnesium mixed with all the other teeny nutrients that are found in a high-magnesium food. The elements in food somehow work together to do more than any one of them can. So, look for lists of "high ___ foods" and use those to guide you to healthy foods that are naturally high in the nutrients you think you might be missing.
if you are using this site to track, are you using items that are already on the site or are you entering your own. i have NEVER EVER trusted any items on this site to track with. I have always entered my own. Correction- I may use the ones for fresh fruit and veggies.
I am not sure I agree with the general population that you get all you need from a healthy diet. If it was 30 years ago or when my parents and grandparents were kids, i would probably agree. But with what man did to the soil, even an apple is not as nutritious as it was 30 or so years ago. I eat a healthy diet. I was tested and there were some nutrients that I needed to supplement. I find that the women's multi i take fits that bill.

If you are eating plenty of fruit and veges, then there is generally no need to worry about supplements.
Because you had your bloods done for magnesium and potassium, AND they came back normal, then you don't need to get more - especially in the supplement form. Too much can have serious consequences.
If you are consuming 2-3 serves of dairy products, then you will be getting enough calcium. It is also in fruit and veges. Once again, with this, if you have too much it can cause a lot of problems, including kidney stones and renal issues.
Despite my best efforts I continue to miss the mark in terms of appropriate intake of potassium, calcium and magnesium. I had lab work done a couple of weeks ago and all of my levels tested within normal limits. I know that if calcium is low the blood will steal calcium from the bones to keep an adequate level in the blood, but does the same concept hold with potassium and magnesium? I know that being above normal ranges can be very dangerous so I don't necessarily want to supplement, but I also want to make sure I'm doing right by my body.
I'm eating a varied diet with fruits and vegetables (not that today was a great example of that) so I don't know what else to do. Anyone else deal with this?
