It’s old news that we should be taking a multivitamin every day, and that women should take calcium supplements. And we know that to be truly healthy inside and out, we need to make sure we’re consuming a wide variety of healthy carbohydrates, fat, and protein as well. But where do the eight vitamins that comprise the vitamin B complex fit into this scheme? When I asked around, not many people could outline exactly what they do or what food sources contain them—which is surprising, because without them, we’d pretty much fall apart. Detailed below, the complete B-list.
B1 (Thiamine)
What It Does: Vitamin B1’s primary purposes are metabolizing carbohydrates, facilitating the release of energy from food, and assisting cardiac and nervous system functions. It’s also been known to strengthen the immune system, reduce stress, neutralize free radicals (thus helping to prevent premature aging and senility), and stave off polyneuritis (the inflammation of multiple nerves at once).
Which Foods Include It: brown rice, egg yolks, wheat germ, brewer’s yeast, oatmeal, bran, bean sprouts, soybeans, cashew nuts, lean pork
B2 (Riboflavin)
What It Does: Vitamin B2, riboflavin, packs a serious punch in terms of its benefits. It plays an essential role in energy production by helping us metabolize proteins, fats, and carbohydrates, and in the formation of red-blood cells and antibodies. In addition, it ensures proper development of our reproductive organs, tissues, eyes, nervous system, and mucous membranes; regulates thyroid activity; strengthens our antibodies; prevents acne; protects the digestive tract; and helps treat nervous-system conditions such as Alzheimer’s, multiple sclerosis, and epilepsy.
Which Foods Include It: The most significant sources of riboflavin are dairy products, brewer’s yeast, and liver. Others include seafood, such as mackerel, eel, shellfish, salmon, and herring; lean meat; mushrooms, broccoli, avocados, dark leafy greens, and asparagus; millet and wild rice; dried peas, sunflower seeds, and beans.
B3 (Niacin)
What It Does: Vitamin B3, also known as niacin or nicotinic acid, is a crystalline substance that occurs naturally in various plant and animal tissues. It’s especially helpful in improving circulation and lowering LDL cholesterol while raising levels of good (HDL) cholesterol. Niacin is necessary for the formation of red blood cells, and helps maintain healthy blood pressure and blood triglyceride levels. It also supports the central nervous system, and high doses have been known to regulate mood. Finally, it keeps the stomach and intestinal tract working smoothly and, like its brethren, assists our bodies in metabolizing carbs, protein, and fat.
