Does Vitamin B Give You Energy?

Why is vitamin B important for our bodies? Does vitamin B give you energy? You might be asking this question, but here's a twist you may not see coming: there's no single "vitamin B." What you might know as "vitamin B" is actually a collection of eight different water-soluble vitamins known as B vitamins.

Each of these 8 B vitamins is unique, with its own benefits, but overall, B vitamins support energy metabolism by helping convert the food you eat into cellular energy. Cellular energy is the fuel our cells need to function, and it differs from perceived energy and focus.^†

Many supplements offer a bundle of B vitamins in a convenient package; this is known as a B-Complex supplement. B-complex vitamins support cellular energy along with brain and nervous system function; let’s break down their individual functions so we can better understand vitamin B complex benefits.^†

What Are the 8 B Vitamins?

B Vitamins are a collection of 8 water-soluble vitamins. That might seem like a lot to keep track of, but don't worry! When you take them one at a time, you'll find understanding your B-complex may be-simple.

Vitamin B1 – Thiamin

Our first B vitamin is found in many foods, though it is particularly rich in whole grains and legumes like beans and lentils.^[1] Thiamin has several benefits in the body; along with helping convert food into cellular energy like other B vitamins, it also supports nervous system function. Nature Made^® offers Vitamin B1 Tablets for those looking to supplement their daily thiamin intake.^†

Vitamin B2 – Riboflavin

Vitamin B2 has one of the more fun names to say of the B vitamin collection. Dietary sources of riboflavin include dairy, eggs, fortified breakfast cereals, almonds, fish and chicken.^[1] Riboflavin supports cellular energy production by helping to convert food into cellular energy.^†

Vitamin B3 – Niacin

Nice! Niacin is vitamin B3, and you may notice it listed on boxes of fortified breads and cereals. In addition to fortified cereals, niacin is also found in poultry and fish.^[1]

Vitamin B5 - Pantothenic Acid

Wait, shouldn't there be a vitamin be-fore this one? There's actually no vitamin designated B4, so we hop on over to B5, pantothenic acid, which is found in meats like chicken and pork, along with plant sources like avocado, sweet potato and lentils!^[1] Vitamin B5 supports normal adrenal function, along with the synthesis of the stress hormone cortisol. It supports the body's natural stress response and helps support cellular energy production. Pantothenic acid is also included in Nature Made^® Focus Boost Capsules as one of 5 essential B vitamins.^†

Vitamin B6 – Pyridoxine

Like other B vitamins, vitamin B6 helps convert food into cellular energy. But vitamin B6 does more than just that! Vitamin B6 supports the production of neurotransmitters that are needed for mood health and helps support healthy brain cell function. Vitamin B6 is also one of the 5 essential B vitamins included in Nature Made Focus Boost Capsules.^†

Vitamin B7 – Biotin

This B vitamin is found in eggs, fish and soybeans, but you can easily find a range of biotin supplements.^[1] Biotin is a skin support nutrient, and many people looking to support healthy skin and hair seek biotin supplementation. Biotin Softgels can function as a daily source of this essential B vitamin, and our Hair-Skin-Nails^▲ Gummies provide 2500 mcg of vitamin B7 to support healthy hair, skin and nails.^†

Vitamin B9 – Folate

Mostly found in leafy greens and legumes, folate is also readily available in its synthetic form, known as folic acid, in fortified breads and cereals.^[1] Folate or folic acid is especially important for pregnant women or women of childbearing age, as it helps support the development of the baby's nervous system. Nature Made Prenatal Multivitamin Tablets are specially formulated with folic acid and key nutrients to support baby's development and mom's overall health. We also offer Folic Acid Tablets for a daily source of this essential nutrient.^†

Vitamin B12 – Cobalamin

Last but not least, vitamin B12 is found in clams, oysters, extra-lean beef, seafood, eggs, milk, yogurt, chicken, cheese and miso. Because most dietary sources of vitamin B12 are animal products, vitamin B12 is an important nutrient for vegetarians and vegans who may not consume enough from their diet alone. Vitamin B12 deficiency can happen if you are not eating enough vitamin B12, or your body isn’t absorbing it; in fact, older adults over 75 are more at risk of B12 deficiency because their absorption rate lowers.^[2] Nature Made Energy^‡ B12 Gummies help reduce fatigue for those low in vitamin B12. Vitamin B12 is included in Nature Made Focus Boost Capsules along with four other B vitamins.^†

How Do B Vitamins Affect Energy Levels?

So, now that you know all the different B Vitamins, instead of asking, "Does vitamin B give you energy?" you're asking, more accurately, "Do all B vitamins give you energy?" B vitamins play a vital role in your body's metabolic process, or metabolism. Your metabolism is how your body takes in what you eat, processes it and turns it into what your body needs.^†

As part of this process, B vitamins help convert the food you eat into cellular energy. For example, thiamin (vitamin B1) is necessary to complete biochemical steps in the energy metabolism cycle to supply your nervous system with energy in the form of ATP.^[3] This is known as cellular energy.^†

Vegetarians and vegans may experience low energy or fatigue if they do not consume enough vitamin B12 in their plant-based diet. Approximately 6% of older adults have deficient levels of vitamin B12, and over 20% have low levels. A vitamin B12 supplement may help reduce fatigue associated with vitamin B12 deficiency if you are in either of those sections of the population.^†

If you’re looking for a quick-acting focus supplement, our Focus Boost Capsules provide a blend of l-theanine and caffeine to help support attention and reduce mental fatigue.^†

How to Choose Vitamin B Supplements for Energy Support

Before you start taking either vitamin B complex or specific B vitamin supplements, consider if you fall into populations more likely to benefit from supplementation. Folic acid, vitamin B9, is an especially important B vitamin for women of childbearing age and pregnant women, which is why Nature Made Prenatal Multivitamin Folic Acid + DHA Softgels are specially formulated with a daily 800 mcg of folic acid to help support the baby's nervous system.^† Adequate folic acid in healthful diets may reduce a woman's risk of having a child with a neural tube defect.

Vegans and strict vegetarians may not consume enough vitamin B12 from their diet alone and may want to consider a supplement.^†

Nature Made Vitamin B12 Time Release tablets extend vitamin absorption so you can get the support you need throughout the day. For all-around B vitamin support, Nature Made Super B Energy Complex includes all 8 B vitamins to help convert the food you eat into cellular energy. When you choose Nature Made, you're choosing the #1 Pharmacist Recommended Vitamin & Supplement Brand.*^†

How Focus Boost Supports Focus and Cellular Energy Production

Support fast-acting focus with our Focus Boost Capsules, which provide a clinically studied, synergistic combination of green tea caffeine and l-theanine to help support attention and reduce mental fatigue that may occur due to everyday stressors.^[4] These daily stressors cause your body to release cortisol, which triggers physiological changes as part of the stress response.^[5]†

This focus supplement works within one hour to support focus and attention, helping with feelings of alertness and mental calm similar to how you might feel after a warm cup of tea in the morning. Each daily capsule also includes 5 essential B vitamins (B6, B12, thiamin, niacin and pantothenic acid) to support cellular energy production and brain cell function.^†
