As someone who has such a poor appetite that I’ve actually developed muscle twitches from calcium and magnesium deficiencies, I can attest that micronutrient supplementation has definitely worked for me and I suspect it’s probably still a good therapy for certain at-risk populations (as other commenters have pointed out).
I’ve yet to read the original studies and reviews (I know, I know— bad commenter! No likes for you!), but I’m curious to see if they address the confounds of (a) which forms of micronutrients were taken (e.g. mag oxide vs mag citrate) and even more importantly, (b) whether these supplements were being taken with the appropriate foods. Sautéed kale is a wonderful (and delicious) accompaniment to just about any micronutrient supplement and has a staggeringly high nutrient-to-calorie ratio— a nice bonus if you have a poor appetite.
