In a perfect world, we’d all eat a superbly balanced weight loss program every single day, getting 100% of the nutritional vitamins and minerals we’d like from contemporary, tasty, and home-cooked meals. In actual life, nonetheless, that not often occurs. That’s the place dietary supplements are available in—theoretically, at the least.
For many years, we have been taught that nutritional vitamins and minerals in tablet kind might assist make up for deficiencies within the typical American weight loss program, or present well being and power boosts that meals alone couldn’t. In latest years, nonetheless, many scientists have modified their tunes, as examine after examine reveals no proof that hottest dietary supplements have any actual well being advantages.
That hasn’t stopped the business from booming, nonetheless. Americans spend greater than $30 billion a 12 months on dietary supplements, and greater than 1/2 of adults have taken a complement prior to now 30 days, in accordance with a 2016 study in JAMA. Many of them repeatedly take multiple, and a few go to extremes: Celebrity chef Giada De Laurentiis lately instructed The Cut that she takes “20 pills a day” on the recommendation of her acupuncturist—“10 in the morning and 10 in the evening.”
But will all these dietary supplements really do you any good? And extra importantly, is it potential to take too many nutritional vitamins? We posed these inquiries to well being and vitamin specialists, and dug into the most recent analysis. Here’s what we discovered.
The newest science on dietary supplements
Scientists know that individuals who eat a lot of vitamin- and mineral-rich meals are inclined to reside longer and more healthy lives. But when these vitamins are served up in tablet kind, it’s nonetheless unclear whether or not they have the identical impact. For instance, a serious 2015 examine discovered that taking dietary dietary supplements does not appear to reduce the risk of cancer.
Several research, together with 1 printed final month within the Journal of the American College of Cardiology, have additionally discovered that common complement use has no net effect on heart health or danger of early loss of life.
“We found a surprising neutrality of effects,” lead creator David Jenkins, MD, professor of drugs and dietary sciences on the University of Toronto, instructed Health. “In other words, it didn’t seem to do anything.” Their findings have been true for multivitamins in addition to for vitamin C, vitamin D, and calcium dietary supplements—all vitamins which have been touted for coronary heart well being prior to now.
In mild of those and different research, most specialists now say that dietary dietary supplements aren’t all they have been as soon as made out to be. “For the average healthy person, you probably don’t need a multivitamin, multimineral supplement,” says Beth Kitchin, PhD, assistant professor of vitamin research on the University of Alabama at Birmingham. “And you definitely don’t want a lot of additional supplements on prime of that.”
In moderation, most gained’t damage you—and, sure, some may assist
That being mentioned, Kitchin does imagine multivitamin might help make up for some deficiencies in an individual’s weight loss program, particularly in the event that they keep away from sure meals teams like meat or dairy. She additionally recommends calcium and vitamin D supplements to a few of her sufferers who’re prone to osteoporosis, “but I always look at their diet first before prescribing them,” she says.
Kitchin takes a day by day multivitamin herself, however she really solely takes 1/2 a dose (1 tablet quite than a serving dimension of 2). “I like to give myself a little extra insurance without overdoing it,” she says.
She tells her sufferers that, in the event that they select to take a multivitamin, to search for 1 with not more than 100% of the day by day worth for anyone nutrient—and to not spend some huge cash, both. “There’s no strong evidence that it will help you, but as long as you keep the dose reasonable, it’s also not going to hurt you,” she says.
Dr. Jenkins agrees that, when taken carefully, most vitamin and mineral dietary supplements gained’t trigger hurt. He additionally stresses that his latest examine solely checked out cardiovascular issues and early loss of life, and that dietary supplements should have advantages in different areas.
“We didn’t look at overall health, we didn’t look at whether people got beautiful hair or skin, or whether your bones got stronger,” he says. “I’m not going to say that some supplements can’t be good for you in those ways.”
You can undoubtedly take too many
But simply because dietary supplements are secure carefully doesn’t mean that more is better. Combining a number of dietary supplements or taking higher-than-recommended doses can enhance the chance that they’ll really trigger hurt, says Kitchin. Plus, as a result of the business shouldn’t be effectively regulated, there isn’t any actual assure that the substances and dosage on the label are correct.
“You really can’t get toxic doses of nutrients through food, but you can absolutely get toxic doses through supplements,” she says.
Taking excessive doses of vitamin C can result in abdomen cramping and diarrhea, for instance. High doses of vitamin A, vitamin D, and different vitamins can result in extra critical, long-term issues—like liver and kidney issues, or a dangerous hardening of blood vessels.
“We’ve learned a very important lesson, in that when we isolate these nutrients out of food and put them in super-high doses, we may have some unintended consequences,” Kitchin says. Plus, some complement substances, together with caffeine powder and crimson yeast rice, have been proven to be probably dangerous even in low doses.
Even if none of your dietary supplements individually exceeds the higher restrict for a given nutrient, combining a number of capsules—like a multivitamin and an extra vitamin D capsule, for instance—might add as much as higher-than-recommended doses. Supplements may interact with each other, says Kitchin, or with drugs you’re already taking.
Always run issues by your physician
It’s a good suggestion to speak together with your physician concerning the dietary supplements you’re taking frequently, says Kitchin, particularly you probably have a well being situation, a dietary restriction, otherwise you’re on any kind of remedy. You must also run any new dietary supplements you’re contemplating by your physician or your pharmacist earlier than you add them to your routine.
It’s additionally necessary to deal with getting your vitamins from meals first, says Dr. Jenkins, and never from dietary supplements. “Pills are not a substitute for a good diet—plant-based, fruit, veggies, whole grains, nuts, and seeds,” he says. “They are packed with what you need.”
And whereas we’re right here, just a few extra ideas about these 20 capsules that Giada apparently takes every single day: The Food Network star elaborated that the majority of these dietary supplements “switch out” everyday, however that she at all times takes a probiotic and a probiotic, together with vitamin D and biotin.

It could also be good to work probiotics (wholesome micro organism) and prebiotics (the vitamins that feed these good bugs) into your day by day routine, however Kitchin says each of these will be present in meals, as effectively. “For the average healthy person, I would recommend eating things like yogurt and kefir,” she says. “Since we don’t have super-clear research yet, it’s hard to recommend specific supplements.”
