This is the second supplement on our list to specifically address hot flashes. That's because they're one of the most common occurrences of heat intolerance.
Fortunately, when it comes to treating hot flashes in menopausal women, there are supplement options. One that medical experts are starting to recommend is vitamin E. A placebo, double-blind, controlled trial conducted in 2007 found that participants taking the vitamin experienced a reduction in the severity of hot flashes [source: Ziaei, et. al].
It's uncertain whether vitamin E can help ease heat intolerance in men and non-menopausal women. However, the supplement does have a number of health benefits. If you'd like to give it a try, start with a lower dosage first to see if it has a positive effect.
