If you have been taking vitamins and minerals, and haven't seen much improvement, please please check if the combinations you are taking enhance each other or cancel each other out.
This is important both for how you are feeling, but also for the health of your kidneys and liver!
For example, most of us need to have more iron and calcium as we get older. But if you take them together at the same time, your body absorbs maybe like 50% of the iron and the rest is filtered out of your body.
Magnesium has become big for a lot of people. But it blocks iron absorption even more than calcium. Magnesium however is great with vitamin D.
There are too many combos to get into but please look at what you are taking and see if you can maximize the effect. Invest in an am/pm pill box and see if that helps with keeping things separate. Also check your multivitamins. While taking some is better than nothing, you may get more out of skipping the multis and just taking the stuff you can maximize in the proper combinations for absorption.
