Supplements can be incredibly beneficial to our overall wellness — just not all of them.<br />Some of them may even have negative effects.<br />Here are a few supplements that dietitians don't swear by:<br />- Apple Cider Vinegar: Apple cider vinegar can be incredibly useful in the correct context. As a supplement? Not so much. Though there aren't many downsides to taking a small dose of apple cider vinegar as a supplement, experts say it won't do much either.<br />- Green Tea Supplements: Ingesting green tea in its liquid form has many positive attributes, but the health claims made by green tea supplement manufacturers are baseless.<br />Touted as a helpful weight loss aid that can reduce the risk of developing cancer, scientific studies do not support such claims.<br />- Vitamin A Supplements: There is nothing wrong with vitamin A, depending on where you're finding it. Experts say in supplement form, vitamin A may be harmful. Especially if you're already not getting enough from your diet. Too much of it might result in headaches or nausea. The over-consumption of vitamin A can even cause birth defects in pregnant women. Experts say to be safe, ditch the supplement and get your vitamin A from fruits and veggies.
