A simplistic approach to nutrition and supplementation On one side of the spectrum cheap multis give a false sense of security. A mere 100% RDA in a base of rice bran, silica or sawdust will might prevent Beriberi, scurvy and other diseases in those with healthy absorption and metabolism but that's about it. On the other end blowing bucks on high end designer formulas usually isn't the answer either.
Age, underlying health issues, activity level, exposure to environmental toxins, anticipated susceptibility to disease based upon familiar history are a few of the things to consider when putting together a supplement plan. Most should begin with an individual assessment which includes the above considerations along with serum testing.
Many will benefit from as much as 5,000% RDA of B vitamins ( careful on B6, pyridoxine ) or may need to dose more than once a day. Understand what your body can and can't store. There are ideal intake levels of zinc for example and it should be taken with copper but not at the same time as other nutrients. Just because it's on the label doesn't mean it is absorbed or bio-available.
As we become good label readers we gain awareness of high levels of adulterants, useless fillers and low grade ingredients. We're likely better off with mixed tocopherols in the right amount than a cheap synthetic acetate which is not only useless but may be harmful. Ditto ergocalciferol instead of cholcalciferol which many will want to supplement at 5000 IU daily not the microgram amounts in the multi. One of my biggest gripes with multis is the listing by name of ingredients that consumers may have heard are beneficial but do not understand the insignificant quantities contained therein. Lutein/zeazanthin is a good example. One can't pop 2 or 3 multis without getting too much selenium for instance where a Brazil nut or two a day is a better source.
The sector that will never take more than one tab or capsule a day should at least take a high quality multi that has been independently assayed someplace like Labdoor. Better than nothing but far from ideal.
The presentation mentions chronic illness. Some of the best resources on supplementation are sites dedicated to cancer and HIV where absorption, metabolism and toxic therapies are factors.

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.
The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
