Earlier this year, we dove into the importance of vitamin B12. Vitamin B12 is like the motor of a car. We need it to keep humming along. It’s an essential vitamin, just like vitamins A, C, D, E, and K. Separately and synergistically, they all keep your body working properly. We love ‘em. We need ‘em. B vitamins, in particular, are crucial for energy, moving oxygen, and more. And while B12 is the most popular of the bunch, there are seven other B vitamins to get to know. Today, we’re chatting about why you need B vitamins, if it’s possible to consume too many, and most importantly, foods that are high in vitamin B.
What Is Vitamin B?
B vitamins (otherwise known as vitamin B complex) are a class of water-soluble vitamins. They’re important for cell metabolism and the synthesis of red blood cells. These vitamins share similar names, but they’re chemically distinct compounds (often coexisting in the same foods)—think dairy, meat, shellfish, dark leafy greens, beans, seeds, and more. Beyond unprocessed foods, they’re also available as dietary supplements.
What Are All of the B Vitamins?
Every day, your body needs a variety of vitamins and nutrients to support your wellbeing. Foods that are high in vitamin B help get that job done. Of the 13 vitamins that your body needs, eight of them are B vitamins:
- Thiamin (B1): Thiamin, or thiamine, enables the body to use carbohydrates as energy. It is essential for glucose metabolism, and it plays a key role in nerve, muscle, and heart function.
- Riboflavin (B2): Like B1, vitamin B2 helps break down proteins, fats, and carbohydrates. It plays a vital role in maintaining the body’s energy supply. Riboflavin helps convert carbohydrates into adenosine triphosphate (ATP).
- Niacin (B3): The key role of niacin in your body is to synthesize two coenzymes which are involved in over 400 biochemical reactions in your body—mainly related to obtaining energy from the food you eat. Your body gets niacin through food, but it also makes small amounts from the amino acid, tryptophan.
- Pantothenic acid (B5): B5 is one of the most important vitamins for human life. It’s necessary for making blood cells, and it helps you convert the food you eat into energy.
- Pyridoxine (B6): Vitamin B6 helps maintain a strong immune system by supporting chemical reactions in the immune system.
- Biotin (B7): Biotin, or vitamin B7, is needed to metabolize fats, carbohydrates, and protein. Deficiency can lead to hair loss and skin problems, but it is rare.
- Folate / folic acid (B9): Your body needs folate to make DNA and other genetic material. It’s especially important during pregnancy! Your body also needs folate for your cells to divide. A form of folate, called folic acid, is used in fortified foods and most dietary supplements.
- Cyanocobalamin (B12): Vitamin B12 is important to maintain the health of your metabolism, blood cells, and nerves.
Why You Need B Vitamins
Vitamin B complex plays a special role in your body. B vitamins help enzymes (which break down what you eat and drink) with several functions, including:
- Releasing energy from proteins, carbohydrates, and fats
- Breaking down amino acids
- Moving oxygen and energy around your body
As the building blocks of a healthy body, B vitamins have a direct impact on your energy levels, appetite, muscle tone, eyesight, brain function, and cell metabolism. Specifically, B vitamins also help your cells grow and multiply. Some B vitamins also aid the body’s production of hemoglobin (very important for red blood cells!). Hemoglobin gives blood its red color. It also helps transport oxygen throughout your body.
Health Benefits of B Vitamins
What are some other health benefits of B vitamins? Immune function, brain health, and help prevent birth defects in a growing fetus, to name a few. Vitamin B6, for example, supports biochemical reactions in your immune system. Vitamin B6 doesn’t often get a chance to shine, but it’s a very hard-working nutrient. As far as brain health is concerned, data suggests that the more B vitamins there are in your blood, the better you’ll perform on tests involving memory, problem-solving, and sentence formation. Furthermore, if you’re a woman of childbearing year, your folate / folic acid needs will increase when you become pregnant. Vitamin B9 can help to reduce your baby’s risk for developing birth defects, including spina bifida and other neural tube defects.
What Is a Water-Soluble Vitamin?
Unlike vitamins A, D, E, and K which are fat-soluble, B vitamins are water-soluble. But, what does this mean? As its name suggests, a water-soluble vitamin can dissolve in water. Water-soluble vitamins are carried to the body’s tissues but are not stored in the body. Because they’re easily absorbed by the body, you won’t store large amounts of them at once. One of the jobs of the kidneys is to remove any excess water-soluble vitamins that aren’t needed.
Can You Get Too Much Vitamin B?
Given that vitamin B is water-soluble, it’s quite unlikely to get too much. If you intake too many B vitamins, no need to fret. You’ll simply excrete them when you urinate. Plus, taking extra vitamin B12 won’t give you more energy than the daily-recommended amount of B12. All of that said, overdose is possible, particularly if you’re taking a supplement without receiving a deficiency diagnosis from your doctor. Always chat with your healthcare provider before making a change to your supplement routine.
What Are Symptoms of Vitamin B Overdose?
Symptoms of a vitamin B complex overdose vary (and again, are not common), but they include: Excessive thirst, abdominal cramps, blurry vision, increased urination, skin flushing, nausea, and more. Furthermore, taking too much vitamin B can lead to nerve damage. On the flip side, if you think you might be deficient in B vitamins (or you’re newly plant-based and want to ensure you’re getting all of the vitamins and minerals you need), schedule an appointment with your health care practitioner.
