Some Michiganders have turned to dietary supplements for the chilly and flu season to spice up their physique’s defenses.
Whereas nutritional vitamins might help enhance the immune system, an excessive amount of of an excellent factor can have unfavourable results, explains Sarah Hutchinson, registered dietitian with Henry Ford Well being.
“Complement toxicity is if 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 lots of or hundreds of proportion factors in extra of what’s really helpful day by day.
For instance, Hutchinson described a state of affairs by which a affected person would possibly take a day by day multivitamin, along with a day by day dose of a vitamin C complement reminiscent of Emergen-C, a zinc complement, and an elderberry complement that additionally incorporates zinc and vitamin C.
“They’re taking one product on prime of the opposite when perhaps they simply want this multivitamin daily or each different day,” she mentioned. “I heard an excellent metaphor not too long ago: If you happen to put extra gas in a automotive, it will not go sooner. In the identical method with nutritional vitamins and minerals, simply because we have now extra, it doesn’t suggest your physique will perform higher.”
Signs of getting an excessive amount of of a vitamin or mineral might be common or nonspecific, reminiscent of headache, stomachache, or coronary heart flutter. Extra critical reactions can embrace 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 troublesome to diagnose the issue by yourself. A blood take a look at might 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 lately to replicate vitamins that many Individuals usually are not getting sufficient of. Labels nonetheless want to incorporate calcium and iron, however as a substitute 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 weight loss plan; Citrus fruits and broccoli, for instance, are good sources of vitamin C. Dietary dietary supplements ought to solely be utilized in circumstances of deficiency, reminiscent of when you wrestle to get sufficient of a specific nutrient naturally.
Hutchinson additionally recommends avoiding dietary supplements that far exceed the day by day suggestions. A great way is to debate nutrient choices with a major care doctor to raised decide which of them are finest, and whether or not a complement might work together negatively with one other treatment.
For instance, the FDA warns that drugs for HIV/AIDS, coronary heart illness, melancholy, organ transplant remedies, and contraception drugs are much less efficient when mixed with an natural complement generally known as St. John’s wort. As well as, the mixture of a number of blood thinners, together with a vitamin E complement, might enhance the chance of inner bleeding or stroke.
Because the common American weight loss plan “has room for enchancment,” Hutchinson mentioned there’s typically nothing flawed with taking a multivitamin. However some are higher than others.
“The very best rule of thumb is to be sure to do not get greater than 100% of the[recommended daily allowance],” she mentioned. “It is far more useful to take smaller doses than to get 100% unexpectedly.”
