>>22435Not to encourage you if you are underweight to an unhealthy degree, but anorexics don't actually die as soon as you'd think. Malnutrition isn't good, but vitamins are buffers for the reactions in your body so the reactions will happen regardless, just far less efficient. Minerals are needed, but if you live in the first world and eat any amount of meat you should be fine enough that your body shouldn't be more than vaguely malnutritioned, but not enough to turn your bones to Swiss cheese from metabolizing and using the minerals stored there. But again, so long as you're not severely undereating of underweight. For some skeletons the BMI isn't totally accurate right at the outskirts of "ok".
You kind of have to look objectively at your body and decide if you are more skin and bone than healthy but if you look healthy skinny then probably the only thing you might have issues with is micronutrients as it's harder to get enough when your calorie requirements are less like in shorter women and those with smaller skeletons overall. I would highly, HIGHLY recommend a multivitamin to be safe, or a green juice powder if you have issues with pills (multivitamins can be a little harsh on sensitive stomachs due to the minerals), especially for iron due to obvious female reasons. Also if you bleed a lot, start taking an iron supplement a day or two before your period starts and during it (every other day if you have a sensitive stomach or eat high iron foods instead). If you're American go for the Walmart brand or other store brand stuff as it's sadly the safest supplements in America (most likely to contain what it claims without extra expensive filler), in Canada you can chose any of them but the cheapest the better, Jamieson and Equate are great quality. More expensive stuff tends to be proprietary blends and molecules with less research behind them but created so they can sell something "unique", sometimes the molecular structure can change everything for the worst and dangerous so trust the basic molecules until at least 10 years of research is out for "alternative" molecular structures.
If you're smaller honestly all your tiredness could literally just be from iron as women need lots and if you don't eat as much it's harder to get. Especially in a world where we don't eat as much organ meats as we once did. If you can stomach them I highly recommend eating organ
