Vitamin B Complex | What do you need to know?

The B group or complex of vitamins plays an important role in maintaining health and physical activity. You may have heard that B-vitamin supplements improve energy levels. This is because many of the functions of vitamin B are related to food metabolism.

Optimal levels of B vitamins can help the body better absorb and use the nutrients from the food you eat. This article will let you know about the benefits of vitamin B complex, as well as food sources and potential signs of deficiency.

From this article you will learn:

• what is vitamin b complex
• vitamin B complex deficiency symptoms
• who should take the complex
• Benefits of B Complex Vitamins
• dosage of B complex

What is a vitamin B complex?

Vitamin B complex is a term used to refer to a group of B vitamins that our body needs to maintain optimal health. Because they are water-soluble and not fat-soluble, they do not accumulate in the body and must be obtained daily from the diet or supplements. B vitamins have a positive effect on appetite, vision, skin, nervous system, and red blood cell formation.

Vitamin B complex includes:

B1 (thiamine) – essential for cell growth, development and function.

B2 (riboflavin) – plays a key role in the use of food for energy.

B3 (niacin) – Plays a role in converting food into energy and aids digestion, skin and nerve function.

B5 (pantothenic acid) – helps convert food into energy; is critical for the production and breakdown of fats.

B6 (pyridoxine) – used for many metabolic functions, immunity and plays a role in brain development.

B7 (biotin) – plays an important role in the metabolism of all three macronutrients (proteins, carbohydrates and fats).

B9 (folate) – is critical for cell division and DNA formation, making it especially important in the diet of pregnant women.

B12 (cobalamin) – similar in function to other B vitamins (red blood cell development, neurological function, DNA formation), but only found naturally in animal sources.

It is worth noting that some B complex vitamin supplements also contain vitamin C, since it is also water soluble.

Food sources of vitamin B complex

B vitamins are present in many animal protein sources such as meat, fish, eggs, milk, and pork. Plant-based sources of B vitamins include leafy greens, beans, whole grains, and nuts.

Because B vitamins are so important to health, they are added to many foods. Foods such as breakfast cereal and bread (because they are so widely consumed) are usually fortified with B vitamins.

Vitamin B deficiency symptoms

When you don’t get enough B vitamins from your diet, a deficiency can manifest itself in a variety of ways. The most common is anemia, when you have low levels of B12 and/or B6 and your blood cannot carry enough oxygen around your body. Anemia can occur in those on a vegan diet, as animal products are a rich source of B vitamins.

Symptoms of anemia include headaches, fatigue, weakness, colds, or dizziness. While there are many causes of anemia, low levels of B6 and B12 can contribute to chronic anemia.

Other common symptoms of vitamin B deficiency appear on the skin, nails and hair, such as rashes or cracked skin. Prolonged thiamine deficiency causes beriberi (tingling/numbness, loss of muscle mass). Chronically low levels of vitamin B3 or niacin lead to a condition known as pellagra, which causes digestive and cognitive problems. Folate affects the production of cells and protein, so its deficiency can affect the growth of adults and children.

Who Should Take Vitamin B Complex?

Although B vitamins are commonly found in food, there are several groups of people who benefit from vitamin B complex supplementation in particular.

• For those on a low calorie diet.
• Vegans (usually low in B12).
• Aging and other conditions affecting food intake.
• People with digestive disorders who may have malabsorption of food.

Your health care provider may order a simple blood test to diagnose a deficiency. As you can see, anyone who does not eat a balanced, high-calorie diet can benefit from a B-complex supplement.

Vitamin B complex properties

The benefits of taking a vitamin B complex are due to its many functions for the normal functioning of the body. In addition to preventing diseases associated with a deficiency of this group of vitamins, such complexes can help increase energy levels and increase the effectiveness of training.

Proper levels of B vitamins improve digestion and nutrient absorption, and keep hair, skin and nails healthy. Ensuring adequate levels of B vitamins can improve mood and cognitive function.

Vitamin B complex dosage and side effects

Since the B vitamins are water soluble, they do not accumulate in the body, and overdose is usually not a concern. However, you may experience side effects from very large doses of any vitamin or supplement.

For example, starting niacin (B3) can cause skin redness, and pantothenic acid (B5) can cause stomach upset.

The following list shows the amount of each B vitamin that adults need daily. Keep in mind that we get most of this amount from food, so the supplement should not contain more than these amounts:

B1 – Thiamin: 1.1-1.2 mg per day 3 mg daily (dairy free, vegans and vegetarians may need more)
B3 – Niacin: 14-16 mg per day
B5 – Pantothenic acid: 5 mg per day
B6 – Pyridoxine: 1.2-1.3 mg per day 7 mg)
B7 – Biotin: 30 mcg of biotin per day
B9 – Folic acid: adults 400 mg per day and pregnant women 600 mg, but not more than 1000 mg
B12 – Cobalamin: 2.4 mg per day

There are two points Things to watch out for: There is a set upper limit for folic acid (B9), meaning that exceeding this amount can be harmful to health. B12 is a vitamin that is usually taken alone because it is not always well absorbed from food sources.

For this reason, it is available in several different oral supplement forms as well as injections.

Conclusions
Many of the B-complex vitamins are found in daily diets, but deficiency can occur due to malnutrition or absorption problems. For this reason, a B complex (on its own or as part of a multivitamin) can help meet your daily needs. Because the B-complex vitamins are water soluble, they do not accumulate in our bodies and must be taken daily.

B Complex MF

Have you experienced Have you ever had side effects from taking B vitamins? For example, nervousness, headaches or unpleasant arousal? This may be due to methylated nutrients!

This article will help you determine if you need a non-methyl supplement.)

B Complex MF contains folinic acid and vitamin B12 in unmethylated forms. It contains folate as folinic acid and B12 as adenosylcobalamin and hydroxocobalamin.

Similarly, the “adeno” and “hydroxo” forms of vitamin B12 can easily be converted to the active form of methylcobalamin. This slower delivery may provide comfort for those who are sensitive to methylated nutrients.† MF Complex does not contain: Methylated B vitamins Methylcobalamin Methylfolate S-adenosylmethionine (SAMe) Cholines Inositol Trimethylglycine (TMG or Betaine) You should never feel sick agitated, restless or nervous after taking the supplement.
