Generally speaking, adults and children should all be able to safely consume a daily multivitamin & mineral formula (MVM), and if needed, calcium & vitamin D supplement, as well as omega-3 fish oil. Also meal replacements or workout shakes formulated for recovery and energy are also fine as long as they are not spiked with herbs or any substances not on the Generally Regarded as Safe (GRAS) list. In other words, a simple protein, fat and carbohydrate drink or nutrition bar formula would be acceptable for most anyone.
Below is our general health recommendation for kids and adults:
Multivitamin & Mineral formula (Proper gender, age or activity specific with at least 600IUs of vitamin D)
Take as directed
Use if you do not meet the daily needs of calcium (~1000-1200 mgs) and vitamin D (1000IU) from sunlight, multivitamin and food intake; kids should always try to achieve requirements through diet
Take 1 daily if not consuming 2-4 svgs/wk of fatty fish
