You May Want to Reconsider Taking Multivitamins
If
taking multivitamins is part of your daily routine, what follows may
just convince you to reconsider. Most people tend to believe that
vitamin supplements are excellent for their health. Yet, across the
board, research conducted on supplements found that placebo-controlled
scientific studies have consistently shown that vitamin supplements do
not in actual fact prevent disease.
Why do we need vitamins?
And
by vitamins, I'm not only referring to nutrients like vitamin A (which
helps maintain good vision), but other minerals too, such as calcium,
potassium, and beta-carotene, all of which serve similar functions in
the body. Prolonged deficiency of certain vitamins can lead to illness
and disease, so in some cases, taking vitamins is vital.
But,
are vitamin supplements necessary for healthy individuals? A varied
diet rich in fruit, vegetables, and whole grains would presumably mean
that you are already reaching your suggested daily intake. But, even if
your diet is not top-notch, many types of processed foods are fortified
with vitamins and minerals too. So, taking a vitamin supplement in
addition to eating well and consuming fortified foods may mean that your
vitamin levels are higher than what is recommended.
The dark side of multivitamins
Is it possible to overdose on
vitamins? Consider this analogy: Would you take a powerful antibiotic
every day, just in case? So, why do we think that it's okay to have
multivitamins, just in case? Needless to say, individuals at risk of a
vitamin deficiency, due to a poor diet, or a preexisting medical
condition should consider supplementing with a multivitamin to address
that deficiency. However, in healthy individuals who don't suspect a
deficiency, the downsides of multivitamins easily outweigh the benefits.
Are multivitamins too much of a good thing?
What
happens when you start pumping too many vitamins and minerals into your
body? Studies on the effects of multivitamin use in more than 400,000
patients found that individuals who took a daily supplement had an
increased mortality rate. In a 2007 study, women who took multivitamin
supplements (vitamin C, E, beta-carotene, selenium, and zinc) increased
their risk of developing skin cancer. Clearly, multivitamin supplements
do have alarming effects. But, can a single vitamin supplement still
hold benefits for the body? Unfortunately, for healthy adults, probably
not.
Vitamin A: This
vitamin is responsible for vision and the immune system. It is found in
bright yellow and orange fruits, and vegetables. Add a quarter cup of
sweet potatoes, a third cup of butternut squash or half a medium-sized
carrot to get your recommended daily value. Vitamin A can also be found
in dark leafy greens - a cup of kale or two cups of spinach will give
you your daily fix. Most breakfast cereals also contain 1- percent of
the recommended daily value per serving.
Getting too much: According to a number of studies, too much vitamin A ingested through supplements has been shown to increase the likelihood of developing lung cancer among smokers. In one study, the supplement increased lung cancer by as much as 28 percent.

Vitamin E: This
fantastic antioxidant can be found in wheat germ, dark leafy greens,
nuts and seeds, and vegetable oils. Cereal will also give you nearly
half of your recommended daily value of vitamin E.
Getting too much: Too much vitamin E can seriously impact your health. One study found that excessive amounts increased a patients' risk of heart failure. Supplemental vitamin E also correlated with increased mortality rates in another study. In a 2011 study conducted on 35,000 men, showed that excessive vitamin E supplements significantly increased the risk of prostate cancer.

Calcium:
Usually recommended to women to build stronger bones as they age. But
in addition to the usual tablet form, three cups of milk and two cups of
yogurt or tofu can provide you with your recommended daily value of
calcium. Fortified sources such as soy or almond milk provide the same
benefit.
Getting too much: Despite calcium being needed for stronger bones, a study found that patients taking calcium supplements were at risk of a hip fracture. Furthermore, it was found that those taking calcium supplements were at a higher risk of death from cardiovascular.

So,
unless your doctor advises you to take a supplement, there is no real
benefit to taking vitamins. In fact, they may just do you more harm than
good!
