In our daily lives we often encounter additional advice from our doctors, friends and relatives. Several American experts (including Dr. Lorraine Maita, a doctor in New Jersey and a graduate of the American Academy of Anti-Aging and Regenerative Medicine) share 5 vitamins and minerals that are simply not needed in the form of supplements - some of them may even to be harmful.
1. Calcium

For many years, the following message has been passed on among women that calcium supplements are crucial for healthy and strong bones. According to Dr. Maita, the latest research shows that calcium supplements may not enter the bones, but instead calcify the arteries and soft tissues, which increases the risk of heart disease.
Moreover, calcium supplements can increase the formation of kidney stones in those who are susceptible.
You can get all the calcium your body needs from the following foods: green leafy vegetables, salmon, sardines, white beans, almonds and broccoli.
2. Vitamin E
It has once been thought to reduce the risk of cardiovascular disease, Alzheimer's disease, cataracts and cancer, but in reality vitamin E may increase some cancer risks.
One study found that the overall risk of death was higher in men and women who took high doses of vitamin E than in those who did not. If you are worried about the level of this vitamin, then the amount of vitamin E in most multivitamins is not enough to cause this adverse effect. You can use vitamin E on your skin to keep it hydrated.
3. Iodine
Although some natural healers recommend supplements, iodine should only be taken under medical supervision. The mineral is most often associated with the thyroid gland, as it is a key component of the hormones produced there, says Dr. Maita. Too little or too much iodine can cause underactive thyroid, known as hypothyroidism, so it's especially important to make sure you don't take iodine when you don't need it. The best way to find out? Ask your doctor to measure the levels of iodine in your urine to determine if your levels are low before taking a supplement.
According to Hara Lucius (an oncologist at the Cancer Centers in America), food in America is already supplemented with iodine, which means that iodine deficiency is rare.
4. Iron
This mineral helps form hemoglobin, a component of your blood that delivers oxygen from your lungs. Iron is also needed for normal cell function and the synthesis of certain hormones. However, you should only take it as a supplement when you have laboratory confirmation of a deficiency from your doctor.
This is because iron overload due to excessive supplementation or dietary intake can damage the liver and possibly other organs such as the pancreas and heart. Too much iron can also cause inflammation of the liver and oxidize in the body, causing cell damage, says Dr. Maitra.
5. Vitamin B6
The eight B vitamins, called B complex, are crucial for optimal health, helping our body turn food into fuel and stimulate healthy skin, memory, pregnancy and more. Because B-complex vitamins are present in many foods - especially those that are part of a healthy diet, such as fruits, vegetables, whole grains, poultry and fish, most of us get enough.
And research shows that taking B6 supplements for a long period of time can actually lead to serious problems. Although vitamin B6 is water-soluble and safe in moderation, taking too much can be toxic, says Dr. Maita. - High doses have been shown to cause abnormal sensations in the nerves called neuropathy.
