These days, all the pieces from bottled water to orange juice appears to have souped-up ranges of nutritional vitamins and minerals in it. Which will sound like a method to assist cowl your dietary bases, particularly in case your weight-reduction plan is lower than stellar. However routinely getting an overload of nutritional vitamins and minerals can harm you.

An excessive amount of vitamin C or zinc may trigger nausea, diarrhea, and abdomen cramps. An excessive amount of selenium may result in hair loss, gastrointestinal upset, fatigue, and delicate nerve injury.

Whereas most individuals don’t get megadoses, in the event you eat a fortified cereal at breakfast, seize an vitality bar between meals, have enriched pasta for dinner, and take a day by day complement, you might simply be over the really helpful day by day consumption of a number of vitamins.

This is what you must know to keep away from overdoing it.

Likelihood is, the unfortified meals you eat aren’t an issue. “It is fairly exhausting to overdo it from meals alone,” says Johanna Dwyer, RD, a senior analysis scientist with the Nationwide Institutes of Well being’s Workplace of Dietary Dietary supplements.

So you may wish to take into consideration the dietary supplements you’re taking and fortified meals or drinks.

“Most individuals do not understand there is not any actual benefit to taking greater than the really helpful quantities of nutritional vitamins and minerals, and so they do not acknowledge there could also be disadvantages,” Dwyer says.

“In the event you’re taking a complement, stick to at least one that is not more than the day by day worth,” Dwyer says. (Day by day worth is the quantity of a vitamin or nutrient that an individual ought to get for optimum well being.)

Speak together with your physician about any dietary supplements you take, together with nutritional vitamins and minerals, and the dose you take, too. That method, your physician might help you retain doses in a protected vary.

“In the event you’re taking a fundamental multivitamin, there is not any have to concern taking an excessive amount of,” says Andrew Shao, PhD, senior vp of scientific and regulatory affairs for the Council for Accountable Diet, a commerce group for the dietary supplements business.

“Most multivitamins have such a large margin of security that even once you’re combining them with fortified meals, it is nonetheless not going to trigger you to keel over,” Shao says.

“I’ve not seen somebody off the road who was taking a poisonous degree of vitamin A or D — these are very uncommon,” says David Katz, MD, director of the Yale College Prevention Analysis Heart in New Haven, CT, whose medical follow focuses on diet. “What I am extra more likely to see is an individual with a dosing degree of dietary supplements that is increased than optimum.”

Scientists do not but know if routinely getting a little bit bit an excessive amount of of a vitamin or mineral (versus a megadose) is an issue, Katz says.

“There is perhaps hints of concern, however they’d be very delicate indicators,” he says.

These pretty delicate signs might embody problem sleeping or concentrating, nerve issues equivalent to numbness or tingling, or feeling extra irritable — relying on the nutrient that is going overboard.

The larger concern, Katz says, is that we’re “garnishing the meals provide with overfortification.”

He says producers have shifted their focus from what they’ve taken out of meals — equivalent to its fats, sugar, or salt — to what they’re placing in, whether or not it is vitamin D, probiotics, or omega-3 fat — no matter nutrient is in vogue.

“When increasingly meals are enhanced, it turns into unimaginable for shoppers to know what dose they’re getting over the course of a day,” Katz says. “Clinicians have to understand we is perhaps introducing new dietary imbalances due to this follow.”

Dwyer says vitamin D, calcium, and folic acid are three vitamins you could get an excessive amount of of, particularly via dietary supplements.

Adults who usually far exceed the 4,000 worldwide items (IUs) day by day protected higher restrict for vitamin D would possibly might find yourself with critical coronary heart issues.

Folic acid is added to enriched grain merchandise — white flours, pasta, rice, breads, and cereals — to assist stop delivery defects in infants on account of folic acid deficiency in pregnant ladies. Whereas folic acid fortification has minimize the variety of delivery defects by 25% to 50%, it might need created different well being issues in folks getting an excessive amount of.

It isn’t exhausting to get greater than 1,000 micrograms of folic acid a day (the protected higher restrict for adults) from fortified meals and dietary supplements frequently. Doing so would possibly cover the indicators of a vitamin B12 deficiency in older adults. Vitamin B12 deficiency can generally result in everlasting nerve injury if left untreated.

There is no want to fret about meals which might be naturally wealthy in folate.

“Most individuals can now get sufficient folic acid with out having to depend on dietary supplements,” Dwyer says.

In actual fact, she says, “most individuals haven’t any drawback [with getting too much vitamins or minerals] if they begin with meals, which is the healthiest and most secure strategy to get them.”
