Some Michiganders have turned to dietary supplements for the chilly and flu season to spice up their physique’s defenses.
Whereas nutritional vitamins may also help enhance the immune system, an excessive amount of of a great factor can have unfavorable results, explains Sarah Hutchinson, registered dietitian with Henry Ford Well being.
“Complement toxicity is whenever you get an excessive amount of of a vitamin or mineral, normally from dietary supplements or artificial sources,” she mentioned. “It is changing into extra of a problem with available dietary dietary supplements.”
It is extremely unusual for people to ingest a poisonous quantity of a specific vitamin or mineral from meals sources alone. However including a number of dietary supplements may end up in taking a whole lot or hundreds of proportion factors in extra of what’s really useful day by day.
For instance, Hutchinson described a scenario wherein a affected person would possibly take a day by day multivitamin, along with a day by day dose of a vitamin C complement resembling Emergen-C, a zinc complement, and an elderberry complement that additionally comprises zinc and vitamin C.
“They’re taking one product on prime of the opposite when perhaps they only want this multivitamin every single day or each different day,” she mentioned. “I heard a great metaphor just lately: In the event you put extra gasoline in a automotive, it will not go quicker. In the identical means with nutritional vitamins and minerals, simply because we have now extra, it does not imply your physique will perform higher.”
Signs of getting an excessive amount of of a vitamin or mineral might be basic or nonspecific, resembling headache, stomachache, or coronary heart flutter. Extra critical reactions can embody blood clots and stroke-like signs, particularly in people with liver or kidney issues.
An excessive amount of of 1 nutrient can really feel like a deficiency in one other, making it tough to diagnose the issue by yourself. A blood check may also help assess unhealthy ranges; So dietary labels might be higher evaluated when deciding which dietary supplements to take.
The required vitamins listed on the everyday Diet Info label have undergone a change in recent times to mirror vitamins that many Individuals should not getting sufficient of. Labels nonetheless want to incorporate calcium and iron, however as an alternative of asking for nutritional vitamins A and C, they now require vitamin D and potassium.
When potential, nutritionists recommend forgoing dietary dietary supplements in favor of a nutrient-dense food regimen; Citrus fruits and broccoli, for instance, are good sources of vitamin C. Dietary dietary supplements ought to solely be utilized in instances of deficiency, resembling should you battle to get sufficient of a specific nutrient naturally.
Hutchinson additionally recommends avoiding dietary supplements that far exceed the day by day suggestions. strategy is to debate nutrient selections along with your main care doctor to find out one of the best acceptable choices to take, and whether or not the complement may work together negatively with one other treatment.
For instance, the FDA warns that drugs for HIV/AIDS, coronary heart illness, despair, organ transplant remedies, and contraception capsules are much less efficient when mixed with an natural complement often called St. John’s wort. As well as, the mix of a number of blood thinners, together with a vitamin E complement, might improve the danger of inside bleeding or stroke.
Because the common American food regimen “has room for enchancment,” Hutchinson mentioned there’s usually nothing fallacious with taking a multivitamin. However some are higher than others.
“The perfect rule of thumb is to be sure you do not get greater than 100% of the[recommended daily allowance],” she mentioned. “It is way more useful to take smaller doses than to get 100% .”
