If you want to have energy that lasts for the entire day, you need to understand what vitamins can help to provide you with the power you need. And if you notice that you are feeling fatigue, lethargy and lack of energy, you may be deficient in at least one of the essential vitamins that help to keep you up and active.

Every vitamin has its own role in keeping you nourished and in good health, but the ones that specifically work to supply you with energy are B vitamins or Vitamin B complex. Here are the eight B vitamins that help to power you up with energy:

1. Vitamin B1 (Thiamin)

Vitamin B1 or thiamin is your body’s provider of strength of the immune system. It works to enhance the synthesis of neurotransmitters to ensure that your brain and nervous system can perform its functions more efficiently. It is also essential for the nourishment of the skin and blood vessels and to optimize the body’s metabolic process.

2. Vitamin B2 (Riboflavin)

This B vitamin works to enable the body to produce energy by way of certain chemical reactions. It improves the body’s oxygen utilization to optimize cellular function and it helps to provide relief from joint pains due to arthritis.

3. Vitamin B3 (Niacin)

Niacin helps to lower high cholesterol which is the cause of many health problems including fatigue and lack of energy. It also works with the other B vitamins to allow the body to produce energy.

4. Vitamin B5 (Pantothenic Acid)

This vitamin provides the body with energy and resistance to combat infections and disease-causing organisms. Its main job is to nourish and strengthen the body’s immune system.

5. Vitamin B6 (Pyridoxine)

Pyridoxine strengthens the arteries and keeps your circulatory system in good health. Efficient circulation is vital in energy production because blood and oxygen are essential to allow the cells to produce energy that the body needs.

6. Vitamin B9 (Folic Acid)

Folic acid is another B vitamin that helps to nourish and protect the arteries. It is also responsible for the development of red blood cells which carry oxygen to the rest of the body to keep it energized. It is an essential nutrient that helps to prevent birth defects in pregnant women.

7. Vitamin B12 (Cyanocobalamin)

Vitamin B12 works with vitamin B9 to form red blood cells. It also helps the body to absorb food efficiently. Foods are the body’s main sources of energy.

8. Biotin

Although it is also known as vitamin H, biotin is a part of the vitamin B complex group of vitamins that help to convert food into energy. Your body uses biotin to metabolize carbohydrates, fats, and amino acids which are the building blocks or protein.

Biotin helps to provide health and nourishment to your nails, hair and skin.

These are the eight B complex vitamins that work together to provide the body with energy. But there are other substances that your body needs to maximize its power, resistance and health. These include iron, magnesium and zinc. The best way to get all of these is through healthy diet, exercise and taking multi-vitamins and minerals supplements.
