Riboflavin is sometimes called the energy vitamin, so for men on the move, this is one of the most important vitamins around. As mentioned previously, the B complex vitamins all work together, but that doesn't stop certain ones from being more important than others.
Riboflavin, like its counterpart niacin, is an essential component of energy production. It works to increase metabolism and is required for a variety of cell processes. It's found in many of the same places as niacin, including almonds and proteins, as well as milk, leafy vegetables, liver, and yeast.
Because it helps in blood movement, riboflavin is especially important for men experiencing a period of growth or if they're eating large amounts of protein to build muscle. There is also evidence that it may be beneficial to men who suffer from migraines or tinnitus (a hearing problem) [source: Evans]. Overdoses are rare because riboflavin is easily absorbed and excreted.
Things are about to get strange as we look at the next vitamin.
