doesn’t pose an acute health risk, excess calcium levels can reduce the absorption of the minerals we care about (zinc and magnesium). Thus, a multivitamin specifically for athletes can safely omit calcium. Supplying superdoses of various micronutrients via poorly formulated supplements will not only fail to provide any benefits, but it can even be harmful. For example, vitamin A (retinol) was traditionally added because it is a vitamin, but it was later discovered that high dosages of retinol could actively harm the liver by cutting off the blood supply to its cells. 66 Due to this, the plant pigment -carotene is often used instead of retinol because it turns into retinol when needed and thus is safer, but it’s also abundant in most people’s diets. A better option would be carotenoids (plant pigments) that tend to be lacking in the average Western diet, such as the sea-based fucoxanthin or the egg- based lutein and zeaxanthin. The vitamin E found in many multivitamins can also be harmful. It’s often surprisingly overdosed on the assumption that including more antioxidants is better and, because it and vitamin C are cheap, both are usually included at high dosages. Unfortunately, not all antioxidants are similar, and regular supplementation of vitamin E above 400 IU per day is now suspected to increase the risk of all-cause mortality. 67 More is not always better. In many cases, supplement companies don’t bother determining optimal dosages of the essential vitamins and minerals for their target publics and simply choose the cheapest forms available. They also may choose needlessly expensive forms that sound nice in marketing copy but don’t confer additional benefits over cheaper forms. Going the cheap route provides higher profit margins, and going the unnecessarily expensive route adds needless expense to both the manufacturer and customer and results in a product that is ultimately less beneficial than it would be if the manufacturing budget were spent more intelligently. Another little gimmick to look for is the use of several forms of the same vitamin or mineral, which makes the product look more impressive (in many customers’ minds, more and fancier-sounding ingredients means a better product). For instance, using four different types of magnesium and calling it the “Magnesium Maximization Blend” looks impressive to the customer but means absolutely nothing in terms of effectiveness. And while we’re on the subject of forms of vitamins and minerals, let’s look at the controversial subject of natural vs. artificial. Many people believe that if something comes from nature, it must be better than something synthetically made. Hence, the all-too-common (and meaningless) marketing claims of “all natural” that we find on all kinds of food products.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
