To support immune health, many people turn to zinc, but Cox reveals why that's not always a good idea. "Zinc supplements have been widely used to help prevent infection, especially during the COVID pandemic, but they can be harmful too. High doses of zinc intake can lead to depletion of copper levels.
"Iron supplementation should never be done without clear instruction from a healthcare professional.

If you're considering giving your child vitamins, Cox says, "The American Academy of Pediatrics stance is that healthy children receiving a normal, well-balanced diet do not need to supplement with vitamins (although they do note the importance of a vitamin D supplement of 400 IU daily for children under 1 and 600 IU daily for children over 1 year of age).

The 13 known vitamins are divided into 2 categories — fat-soluble and water-soluble ( 1 ).
Given that fat-soluble vitamins can accumulate in the body, these nutrients are more likely to lead to toxicity than water- soluble vitamins.
So, yes, I still recommend a multivitamin for most people, but read the labels. Look for a multi with no more than 3,500 IU of vitamin A and no more than 30 IU of vitamin E. Medical research supports these values as safe doses that can compensate for dietary insufficiency.

The FDA knows that hydrogenated fats are bad for us. The 2010 Dietary Guidelines for Americans [4] specifically states: “Keep trans fatty acid consumption as low as possible by limiting foods that contain synthetic sources of trans fats, such as partially hydrogenated oils, and by limiting other solid fats.”.
More than 6,300 reports of serious adverse events associated with dietary supplements, including vitamins and herbs, streamed into the FDA from supplement companies, consumers, health-care providers, and others between 2007 and mid-April of 2012.

Water-soluble vitamins, such as most of the B vitamin s, are easily excreted from the body every day in the urine. These vitamins are not stored in the same way and are less likely to ever cause toxicity.
Vitamin A—also known as retinol—is largely derived from beta-carotene, the red/orange pigment in many vegetables such as carrots. Vitamin A is another powerful antioxidant.

Although vitamin A is known to be important for bone growth, taking excess vitamin A is not necessarily beneficial. Vitamin A deficiency is associated with poor bone growth, but excess vitamin A results in increased bone resorption (bone clearance) with fragile bones and an increased risk of fracture. 5.
