<!-- UNPLACED NOTE: on nutrients that the calculator deems excessive: | |||
* The UL for iron can be set higher when dealing with vegan diets with nonheme-only iron. Side note: the target for iron is set conservatively as well, in the ''other'' direction; it's high enough to be sufficient even with a vegan diet that has only nonheme iron. {{cn}} | |||
* The UL for niacin is set conservatively low to prevent a ''niacin flush'' when consuming a lot of niacin at once. The same nutritionists also mention that a niacin flush is completely harmless and maybe even beneficial, but might can feel like a "symptom" and might cause unnecessary worry for people who take a supplement for the first time. | |||
* The UL for folate was set low to handle cases where that level of folate is combined with a lack other nutrients (such as taking a folate-only supplement, not multivitamin). For people who get enough of every nutrient, the UL for folate would be higher. {{cn}} | |||
* The UL for manganese is low because there are limited studies on it; no one in any of the studies had any manganese toxicity from food, so nutritionists just set the UL to the highest intake seen ''so far''. | |||
* In a perfect world, a multivitamin could be customized the diet, to not have the nutrients that are already naturally abundant(close to their ULs)in the foods. But in any case, it's not a big deal. | |||
* <small>For these above points, the term "UL" stands for "upper level" or "tolerable upper level" of a nutrient.</small> | |||
One excess that might be some cause for concern is magnesium (loose stools but no other harm in this case). Maybe the diets that exceed the UL could be readjusted. <sup>[TODO]</sup> | |||
