nutrient for men

This necessary nutrient is a powerful immune booster, and some studies suggest it may prevent skin and bladder cancer. Additionally, B6 protects against the formation of kidney stones (a problem that affects twice as many men as women) and can help prevent restless sleep. Your need only two milligrams of vitamin B6 daily—about the amount in two large bananas. Active men need a few milligrams more, since it’s burned up during exercise, says Paula Trumbo, Ph.D., assistant professor of nutritional biochemistry at Purdue University. Other dietary sources include chicken and fish, liver, potatoes, avocados and sunflower seed. High doses of B6 supplements can be toxic over time, so experts recommend taking no more than 50 milligrams a day.
