Vitamin B is crucial to our health. Learn about the various types, benefits and the best Vitamin B complex supplements you could take to ensure your well-being.

What Is Vitamin B Complex?

Best Vitamin B Complex Supplements

The B vitamins are water-soluble where they are eliminated via the urine. It is vital to monitor our daily intake of essential B vitamins by eating a healthy, well-balanced diet. Due to the hectic lifestyle of most individuals at the present, a healthy diet can be complemented with a vitamin B complex supplement.

As B vitamins are water-soluble, they could not be stored in the body which is why it is necessary to include them in the diet daily. The B vitamins can be depleted by refined sugars, alcohol, caffeine, and nicotine.

Let us take a closer look at each component below. (1)

  • Thiamine (vitamin B1) – This has several vital functions including working with other B vitamins to help break down and release energy from food as well as keeping the nervous system in check. Thiamine is present in various food including fresh and dried fruit, vegetables, liver, eggs and wholegrain bread.
  • Riboflavin (vitamin B2) – Contributes to the maintenance of the eyes, skin, nervous system and metabolism. Riboflavin is found in eggs, milk, fortified cereals and rice.
  • Niacin (vitamin B3) – There are 2 forms of niacin – nicotinic acid and nicotinamide which are both present in food. Niacin contributes to normal metabolism and promotes the normal functioning of the nervous system. Ideal sources include fish, meat, wheat flour, milk, and eggs.
  • Pantothenic acid (vitamin B5) – Has various functions such as releasing energy from food eaten and reducing fatigue. It is present in most foods such as beef, chicken, potatoes, tomatoes, broccoli, eggs, and whole grains.
  • Pyridoxine (vitamin B6) – This contributes to normal energy levels to allow the body to utilize and store energy and aids with the formation of red blood cells. It is found in a variety of foods such as poultry, pork, fish, eggs, bread, whole cereals, vegetables, peanuts, soya beans, potatoes, and milk.
  • Biotin – Contributes to the normal metabolism of the body. Biotin is naturally present in various foods such as liver, egg yolk, yeast, nuts, seeds, salmon and avocados.
  • Folic acid – It is folate in its natural form. It has vital functions in the body such as working with vitamin B12 to form healthy red blood cells and lowers the risk of defects in the central nervous system. Good sources include liver, green leafy vegetables, chickpeas, and fortified cereals. Folic acid could not be stored in the body which is why it is necessary for the diet daily.
  • Cyanocobalamin (vitamin B12) – This has various functions and contributes to the production of red blood cells, releasing energy from foods eaten and supports normal functioning of the nervous system. It is present in salmon, meat, milk, cheese, eggs, and some fortified cereals.


Health Benefits Of Vitamin B Complex

The B vitamins play a vital role in overall health. Some of the health benefits of the B vitamins are the following:

  • Gene regulation – The body requires only 400 mcg of folic acid daily to maintain overall health. (2) This small amount is utilized by the body to synthesize new cells and genes especially during periods of growth and healing. Folic acid also aids in the repair of damaged cells which slows the aging process and necessary to produce chemical compounds specifically methyl groups (CH3) which control gene activity such as suppressing any cancer-promoting genes.
  • Lower the risk for heart disease –According to a scientific analysis, a drop in the level of folic acid can lead to an increase in the blood levels of homocysteine. This is a chemical that damages the blood vessel walls and allows the buildup of cholesterol.
  • Mood regulation – The B vitamins have been recognized as anti-stress nutrients. A study has indicated that most of the vitamins have a direct effect on perception and mood. Vitamin B1 can help improve overall mood. Vitamin B6 is also necessary to produce serotonin which is a neurotransmitter with antidepressant benefits.
  • Blood sugar control – Vitamin B1 and biotin are essential in maintaining normal blood sugar levels. The body requires biotin to produce insulin which is a hormone that regulates the blood sugar levels. (3)
  • Improve cognitive function – Using vitamin B12 can restore cognitive function among those with vitamin B12 deficiency. Some clinical studies suggest that deficiency in vitamin B12 can mimic Alzheimer’s disease and other forms of dementia. Other B complex vitamins such as folic acid and niacin are also useful in combination with vitamin B12.
  • Macular degeneration – Using a vitamin B complex supplement can lower the risk for age-related macular degeneration.(4)

How To Take Vitamin B Complex

The recommended daily allowance (RDA) for B vitamins depends on the age, overall health, and other factors. Most can get an adequate intake of these nutrients from a healthy, well-balanced diet. Certain health conditions or lifestyles might influence the recommended intake of the vitamins you need.

Individuals with malabsorption disorders or other chronic health conditions, drink large amounts of alcoholic beverages, had gastric bypass surgery, under parenteral nutrition or the elderly might require dietary supplements containing B vitamins.

Consult a doctor if you have concerns about your intake of B vitamins. Some of the supplements containing the vitamins might interact with certain medications. Pregnant and nursing women must see a doctor since they require more of each nutrient.

Precautions And Side Effects of Vitamin B Complex

There are potential side effects when taking vitamin B complex supplements. Following the recommended daily intake prevents any undesirable side effects. The vitamins are widely classified as safe however high levels can lead to some side effects.

Some of the possible side effects include:

  • Abdominal pain
  • Black-colored stools
  • Constipation
  • Nausea
  • Vomiting
  • Diarrhea
  • Frequent urination
  • Itchiness
  • Redness of the skin

In rare instances, large doses of B vitamins can lead to allergic reactions such as itchiness and skin rashes. The effects of each vitamin vary and are often uncommon. Nevertheless, the side effects are likely if these vitamins are combined in large doses.

Pregnancy and breastfeeding concerns

Inform the doctor if you are pregnant before using a supplement. Most supplements are safe to use during pregnancy if used as instructed. Spinal cord birth defects can be prevented by maintaining the right intake of folic acid during pregnancy.

Since the vitamins can pass into breast milk, it is best to consult a doctor first before breastfeeding. Although there are no reports of detrimental issues among nursing infants.


If you are using a vitamin B complex supplement under the direction of your doctor, there are possible drug interactions. Do not stop, start or change the dosage of any medication unless consulting the doctor first.

When using a supplement for the first time, inform your doctor of all prescription and over-the-counter/herbal products you are using.

There is also a likelihood for the B vitamins to disrupt with some laboratory tests (urobilinogen or intrinsic factor antibodies) leading to false test results. (5)

How to Choose the Right Vitamin B Complex Supplement

Most of the vitamin B complex supplements have some variability in their components, usually with some form or combination of B vitamins. Due to this, you must identify which vitamin B complex supplement is a suitable choice for you.

  • When choosing a product, check if it contains any fillers, synthetic dyes or coloring as well as artificial additives since these can potentially cause side effects or dilute the quality of the product.
  • Check the label for the list of vitamins included in the supplement.
  • Look for reputable brands supported by concrete scientific background as well as offering strong value especially those that are Good Manufacturing Practices (GMP) compliant.
  • Check if the supplements are in the most biologically active and absorbable forms. Most formulations include vitamins in their most commonly used and often cheap form. The bioactive form provides superior action and health benefits. This is an advantage since you have a better value from a smaller dosage with better absorption. Remember that not all supplements are created equal since some use poorly absorbed forms.
  • Among B vitamins, the ingredients vary in dosage for every brand. There is no specific dosage for each, but it should be at least 100% of the recommended daily allowance (RDA).
  • As water-soluble, the body can store some of the B vitamins but absorbed, used and eliminated. When using a supplement, expect the urine to turn yellowish. In case the urine will not turn at least slightly yellow than normal, the dosage might be too low.

Where to Buy Vitamin B Complex

You can get Vitamin B Complex in pharmacies or health stores. There are also various suppliers of vitamin B complex supplements available online. When comparing the different brands of vitamin B complex supplements in a hassle-free manner, Amazon is the ideal place to start. You can also find reviews from other buyers to find the right one for your needs.
