How We Chose the Best Vitamin B Complex Supplements

We chose our picks for the best B vitamin complex supplements using a combination of criteria, including: product quality and safety, reputation of the manufacturer, third-party certification status, affordability and customer reviews.

What Is Vitamin B?

“Vitamin B” is somewhat of a misnomer, as there are actually eight types of B vitamins that form the vitamin B complex family.

B-complex vitamins are water-soluble vitamins generally involved in metabolic processes. They help the body convert carbohydrates into sources of energy it can use to carry out physiological and neurological functions.

Because there are multiple types of B vitamins, vitamin B is implicated in a range of bodily functions from head to toe, including immunity, heart health, cell formation, hormone regulation, brain function and DNA synthesis.

The 8 types of vitamin B

  • Vitamin B1 (thiamine)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6 (pyridoxine)
  • Vitamin B7 (biotin)
  • Vitamin B9 (folate)
  • Vitamin B12 (cobalamin)

Vitamin B complexes

Vitamin B complexes contain multiple B vitamins within one serving unit, whether it be in tablet, capsule, softgel, gummy or liquid form. Complex supplements typically contain all eight B vitamins; however, some don’t.

How to Take a B Vitamin Complex

A vitamin B complex supplement is taken by mouth, usually once daily or as directed. Follow all directions on the product package. If you have any questions, consult your doctor or a licensed healthcare professional.

If you are taking a vitamin B complex that contains vitamin C, take the supplement by mouth with a full glass of water (eight ounces/240 milliliters) unless your physician directs you otherwise.

If you are taking gummies or chewable tablets, chew them thoroughly before swallowing.

If you are taking a liquid B vitamin complex, use a medication-measuring tool to carefully measure the dose. Do not use a household spoon. Some liquid products must be shaken before each dose. Follow the directions on the label carefully to get the most benefit.

B vitamin complex supplements should be taken regularly over an extended period of time in order to get the most benefit from them.

Who Can Benefit from a B Vitamin Complex?

The B complex vitamins are essential vitamins, meaning they cannot be synthesized by the human body, so they must be consumed in food. Thus, a B vitamin complex supplement will benefit anyone failing to achieve the recommended daily intake of vitamin B from their diet.

Additionally, older adults, people with restricted diets (e.g. vegetarians and vegans) and individuals who have conditions that limit their ability to absorb vitamin B from food may benefit from taking B vitamin complex supplements.

A vitamin B complex supplement is also beneficial to people with a history of, or susceptibility to vitamin B deficiency, especially vitamin B12 deficiency.

Lastly, a B vitamin complex supplement with vitamin B12 (cobalamin) is recommended for women who are pregnant or breastfeeding and follow vegetarian or vegan diets.

The Best Time to Take a Vitamin B Complex

The best time to take vitamin B complex supplements is whatever time is most convenient for you. However, because vitamin B complex helps the body convert food into energy, you might consider taking your supplement early in the day with a meal. This way, you’ll be primed to enjoy certain health benefits from your supplement throughout the day (e.g. increased energy levels).

What to Look for in a Vitamin B Complex

Finding the right vitamin B complex supplement can be a hassle, as there are dozens of options to choose from. You can simplify your purchasing decision by looking at the vitamin’s dosage, form and cost.

Dosage

A vitamin B complex supplement will have varying amounts of each B vitamin depending on the manufacturer. For instance, some supplements may include an extra amount of one type of B vitamin while excluding another type of B vitamin altogether.

A balanced vitamin B complex supplement will include all eight B vitamins and contain at least 100 percent of the recommended daily value. If you are interested in getting a high dose of a particular B vitamin, choose a supplement that contains a high concentration of that vitamin.

Form

Vitamin B complex supplements come in multiple forms. Tablets, capsules and softgels are swallowed. Chewable tablets and gummies are chewed. Liquid supplements can be mixed with beverages or food.

You should choose whichever form is most comfortable for you to take on a daily basis.

Cost

A one-month supply of vitamin B complex can range from two to $75.

FAQs

What are the symptoms of vitamin B complex deficiency?

The symptoms of B vitamin deficiencies vary depending on the B vitamin.

Vitamin B12 deficiency typically carries a higher risk rate of deficiency than the other B vitamins. The symptoms of vitamin B12 deficiency include:

  • Anemia
  • Seizures
  • Vision loss
  • Fatigue
  • Weakness
  • Memory loss, confusion
  • Dementia
  • Depression
  • Pale yellow skin color
  • Mouth ulcers and canker sores
  • Constipation
  • Vision disturbances
  • Balance issues, difficulty walking
  • Tingling in hands and legs

How long does it take vitamin B complex to work?

Anecdotal evidence from individual users of vitamin B complex suggests that the effects of vitamin B complex can be felt immediately. However, research has shown that at least two weeks of consistent daily intake are required to feel the health effects of vitamin B complex.

How much B complex should I take a day?

In general, you should take one serving of a B complex supplement daily.

The recommended daily intake of each individual B-complex vitamin varies and depends on your age, sex and medical history.

According to the National Institutes of Health (NIH), the recommended daily intake for women is:

  • Vitamin B1: 1.1 milligrams
  • Vitamin B2: 1.1 milligrams
  • Vitamin B3: 14 milligrams NE
  • Vitamin B5: 5 milligrams
  • Vitamin B6: 1.3 milligrams
  • Vitamin B7: 30 micrograms
  • Vitamin B9: 400 micrograms DFE
  • Vitamin B12: 2.4 micrograms

For men, the NIH recommends the following daily intake:

  • Vitamin B1: 1.2 milligrams
  • Vitamin B2: 1.3 milligrams
  • Vitamin B3: 16 milligrams NE
  • Vitamin B5: 5 milligrams
  • Vitamin B6: 1.3 milligrams
  • Vitamin B7: 30 micrograms
  • Vitamin B9: 400 micrograms DFE
  • Vitamin B12: 2.4 micrograms

Older adults, pregnant women and people with digestion issues or other medical conditions may need a higher daily intake of B vitamins. Talk with your doctor to receive dosage information tailored to your unique health needs.

Does B complex make you sleepy?

B complex does not typically make you sleepy. In fact, taking a vitamin B complex supplement may increase your energy level and alertness.

Does B complex cause weight gain?

B complex on its own does not typically cause weight gain. B-complex vitamins are involved in metabolism and help the body convert food into usable energy sources. B complex supplementation combined with a low caloric diet and exercise may promote weight loss. On the other hand, B complex supplementation combined with a high caloric diet and weight lifting may help increase muscle mass.

Final Thoughts

A vitamin B complex supplement is by no means a magic pill, despite its many health benefits. It’s important to remember that a vitamin B complex supplement is meant to complement, not replace, a healthy diet and regular exercise.

If you suffer from any of the medical conditions that vitamin B is thought to help prevent or treat, do not rely on a vitamin B supplement as a sole method of treatment. In the face of disease, supplements must be combined with additional therapeutic interventions approved by the American Medical Association or another official medical organization.

Lastly, always consult your doctor before starting a new supplement regimen.
