\"vitamin<\/p>\n

Clinical trials involving vitamin E supplementation have been mixed\u00a0\u2013 some showed benefits, while others did not.\u00a0Some trials even\u00a0reported negative\u00a0outcomes associated with taking vitamin E.<\/span><\/p>\n

Is it time to\u00a0ditch your vitamin E supplement?<\/p>\n

Perhaps – but find out why first.<\/p>\n

Although it wasn’t the first trial to show negative effects of these supplements, the\u00a0SELECT cancer prevention study showed that\u00a0men who took 400 IU of vitamin E each day had\u00a0an increased risk of developing prostate cancer. Based on this and a few other quality studies, the Linus Pauling Institute ceased\u00a0recommendations for high-dose vitamin E supplements.<\/p>\n

But remember: no matter what a clinical trial on supplements shows us, vitamin E is still important for\u00a0your health. It has important\u00a0antioxidant roles in cell membranes that can affect the function of nerves and organs and mitigate oxidative stress throughout the body. E\u00a0is also\u00a0critical in brain development and, therefore, is especially needed during pregnancy. Research studies on Alzheimer\u2019s disease, lung function, and risk for miscarriage have shown positive results with supplementation, but much of the data is preliminary and requires further evaluation.<\/p>\n

At the LPI, Maret Traber,\u00a0PhD explores the health effects and metabolic functions of vitamin E. Along with her collaborators at Tufts, Dr. Traber\u2019s research team used a labeled version of the vitamin in collard greens to show that blood lipids – like cholesterol – can alter how long alpha tocopherol (one form of vitamin E)\u00a0remains in the body.\"Maret<\/p>\n

Since it dissolves in fat, vitamin E normally travels with blood lipids into tissues. People with chronically high blood lipids have trouble clearing them \u2013 forcing\u00a0vitamin E to remains in the blood stream. That sounds like a good thing until you think about where it\u00a0is NOT\u00a0going: if more E stays in the blood, less may be getting into tissues. This is especially problematic in people with metabolic syndrome, where high lipids are associated with inflammation, and a higher demand for antioxidants\u00a0like vitamin E\u00a0in tissues.<\/p>\n

\"Vitamin<\/a>The current evidence suggests most people\u00a0are not eating enough vitamin E.\u00a0Estimates are that over 90% of the adults in the US do not reach the recommended levels of\u00a0vitamin E per day in the food they eat to maintain good health. Children and teenagers are also falling short.<\/p>\n

A\u00a0change in the recommendations or recent headlines\u00a0should no reason to\u00a0avoid vitamin E. \u00a0The LPI\u00a0supports the recommendation by the Institute of Medicine of obtaining 22.5 IU\/day of alpha tocopherol. This can be achieved through eating rich food sources, including almonds, sunflower seeds, wheat germ, olive oil, and vegetables that are naturally oily (like avocados).<\/p>\n

However, if you aren\u2019t eating enough E, you’re not alone. To make sure you get what you need, the\u00a0LPI now recommends taking a multivitamin supplement containing 100% of the Daily Value for alpha tocopherol.\u00a0Clinical trials like SELECT only saw negative health outcomes of\u00a0vitamin E when\u00a0far exceeding these levels, so the amount\u00a0in many\u00a0multivitamins is generally considered safe.<\/p>\n

Along with other research topics, the LPI\u00a0highlighted vitamin E in the 2015\u00a0Diet and Optimum Health conference. Top researchers in the field with breaking research on the subject, including Dr. Traber,\u00a0discussed vitamin E\u2019s role in stroke and metabolic syndrome, the prevalence of deficiency, and the interactions with vitamin C.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
