The Vitamin B complex is a collection of eight B vitamins that work together to conduct vital tasks in your body.
The eight different types of B vitamins are water-soluble vitamins that are necessary for many different body processes. The diet alone can supply many people with all the B vitamins they need, and there is no proof that consuming more B vitamins than the body needs is beneficial.
Still, there are certain groups of people who might benefit from taking a B complex supplement: older adults, pregnant women, people with gastrointestinal disorders, people with restricted diets, and people who have had bariatric surgery.
Explore the world of B vitamins in this article, including what vitamin B complex is, how it helps your health, and if it’s the right supplement for you. We’ll discover the actions of this dynamic complex of eight B vitamins and how it can improve your energy and overall well-being.
What is B-complex vitamin?
Vitamin B, encompassing a range of vital nutrients such as B1, B2, and B12, plays a fundamental role in supporting optimal body functioning. In particular, supplements that contain all eight of the B vitamins in one easy-to-take tablet are called vitamin B complex. This ensures that people get complete support for their general health and wellbeing. Since vitamin B is soluble in water, it is possible that the body does not process it. This is why your diet needs to provide them every day. The maintenance of good health depends on vitamin B, which plays numerous important roles.
What are the benefits of B vitamins?
Vitamin B complex supplements are a group of essential nutrients that consist of eight different vitamins, specifically B1, B2, B3, B5, B6, B7, B9, and B12, each playing a distinct role in supporting various aspects of health and well-being. Vitamin B1, for example, is essential for the body’s cells to grow, develop, and function. In order to help the body turn food into energy, other vitamins, like B2, collaborate with other B vitamins. Niacin (B3) is mostly produced by food and is necessary for healthy cell function. B2 transforms B6 into a form that is useful.
Vitamin B6 is necessary for immune system function and is needed by the body to use and store protein and carbohydrates from food as glycogen. Vitamin B5 breaks down fats and carbohydrates for energy and aids in the body’s utilization of other vitamins, such as riboflavin (found in B2).
Proteins, fats, and carbohydrates from food are all converted by the body into energy with the aid of B7. Moreover, it is required for the synthesis of fatty acids, which support and enhance general health, as well as the maintenance of healthy bones and hair. The nutrient vitamin B9, or folate, is essential for maintaining cellular function because it helps make and preserve DNA, the basic genetic code that all cells in the body use as a guide. As for vitamin B12, it’s a necessary nutrient that helps the body’s processes related to protein metabolism.
Who should get B-complex vitamin?
The majority of foods contain B vitamins, so if you eat a well-balanced diet, you should not have any problems becoming deficient in them. But under some conditions, B vitamins become even more important, necessitating the need for supplements.
The potential beneficiaries of vitamin B-complex supplementation are examined in the following sections:
- Pregnant people
During pregnancy, the demand for essential B vitamins, including vitamin B12 and folate, significantly increases as these nutrients play a crucial role in supporting proper fetal development and ensuring the baby’s growth and health throughout the gestation period. These vitamins are particularly vital for preventing neural tube defects and supporting overall maternal and infant well-being.
It is imperative to supplement with a B-complex vitamin for individuals who are pregnant, nursing, or chest-feeding, particularly those who eat vegetarian or vegan diets.
An insufficient amount of B12 or folate either during pregnancy or during nursing may cause serious brain damage or birth defects in the developing child.
- Older adults
Studies indicate that vitamin B12 deficiency is more common in older adults. Higher B12 levels may help prevent the aging of the brain, according to some research. More investigation is necessary to validate this discovery, though.
As per a systematic review and meta-analysis, depression in the elderly population may be linked to low levels of vitamin B9, folate (a dietary equivalent of folic acid), and B12.
- Those with certain medical conditions
Vitamin deficiencies, particularly those involving B vitamins, are more common in people with specific medical conditions, including alcoholism, hypothyroidism, Crohn’s disease, celiac disease, cancer, and anorexia.
Furthermore, a folate deficiency and other health issues may result from the MTHFR genetic mutation impact on how your body metabolizes folate.
Moreover, B vitamin deficiencies are more common in those who have had specific weight-loss surgeries.
in situations like these, individuals are commonly recommended to include a B-complex vitamin as part of their daily regimen in order to remedy any existing deficiencies or prevent new ones from occurring.
- Vegetarians and vegans
Vitamin B12 is an essential nutrient that can be obtained naturally from a variety of animal-based sources such as meats like beef, poultry, and pork, as well as dairy products including milk, cheese, and yogurt, along with eggs and different types of seafood like fish and shellfish.
If strict vegetarians and vegans don’t consume enough fortified foods or supplements containing this vitamin, they may become deficient in B12.
People who choose to follow vegan or vegetarian diets may find that they are getting adequate of these vital nutrients if they take a daily B-complex vitamin.
Which foods are enriched with B-complex vitamin?
B vitamins are widely available, so obtaining adequate through diet is simple. Consuming a diverse range of food items is the optimal way to obtain B vitamins. This makes it more likely that you will receive adequate of each kind.
Vitamin B can be found in milk, cheese, eggs, red meat, chicken, fish, shellfish, spinach, vegetables, whole grains and cereals, kidney beans, black beans, chickpeas, nuts and seeds, banana, watermelon, soy products, wheat germ, yeast and nutritional yeast.
What is the daily dosage of vitamin B complex?
While there isn’t a standardized daily intake of vitamin B listed in tables, it is important to note that vitamin B supplements are usually quantified using milligrams (mg) or micrograms (mcg) depending on the specific type of vitamin B being consumed. As a result, the amounts of each vitamin in various supplements will vary.
Likewise, there are no recognized Recommended Dietary Allowance (RDA) standards for supplements containing the B-complex.
That being said, the National Institutes of Health’s Dietary Supplement Fact Sheets contain established RDAs and ULs for each of the individual B vitamins themselves.
It is common for supplement ingredient labels to show higher amounts of B vitamins than the Recommended Dietary Allowance (RDA), which may catch your attention as you browse through the information on the product packaging. The amount that your body can truly absorb and use the vitamins depends on a number of factors, which affect the bioavailability of nutrients. Supplement manufacturers often exceed the recommended daily allowance (RDA) because your body might not utilize all of the additional amount.
You may also be more vulnerable to a deficiency if you take a vegetarian or vegan diet, drink alcohol frequently, or have had stomach or weight loss surgery.
Vitamins B6, B12, and folate may be more necessary for those who are expecting or nursing a child. The following are specific dosage guidelines for vegans and expectant mothers:
- Vegetarians and vegans: Vegetarians who eat dairy and eggs should supplement with 250 micrograms of vitamin B12 every few days, while vegans should take this dosage daily.
- Pregnancy: 400 mcg of folic acid, or folate, should be consumed daily by women who may become pregnant, according to the CDC.
What are the side effects of B-complex vitamin?
It’s highly improbable that you will adhere strictly to the prescription of a B-complex supplement or inadvertently consume excessive amounts of B vitamins, given their water-soluble nature that facilitates their efficient excretion from the body, minimizing the risk of toxicity or overdose. On the other hand, taking supplements that are overly high in unnecessary amounts of B vitamins may cause major adverse effects.
Excessively high doses of some B vitamins can be harmful, even though a standard dosage doesn’t appear to be harmful. See a clinician before taking B complex supplements at very high doses.
During your consultation, it’s important to openly express your health objectives and the reasons behind considering supplementation. Your healthcare provider will evaluate your individual situation to ascertain if incorporating supplements aligns with your treatment needs.
Potential adverse effects of Vitamin B Complex:
- High blood sugar: Nicotinic acid, a synthetic version of vitamin B3, has the ability to elevate blood sugar levels at high doses. Diabetes medication interactions may result from this. Nicotinic acid doses should be kept low for people with diabetes or elevated blood sugar.
- Excess nicotinic acid: Low blood pressure, exhaustion, headaches, rashes, and liver damage can also result from excessive nicotinic acid consumption.
- Excess nicotinamide: An elevated risk of diarrhea and bleeding is associated with high dosages of nicotinamide, another form of vitamin B3. At 500 mg per day, this can happen. Over 3,000 mg can damage the liver and induce vomiting.
- Excess folic acid: A kind of anemia brought on by a vitamin B12 deficiency can be concealed by taking more than 1,000 micrograms of folic acid daily.
What are the symptoms of vitamin B deficiency?
Anemia and other symptoms can arise from a vitamin B deficiency, according to the National Health Service (NHS) in the United Kingdom.
Insufficient vitamin B levels can cause:
- Fatigue and weakness
- Diarrhea or constipation
- Loss of appetite and weight loss
- Problems with balance
- Depression
- Cognitive difficulties
- Mouth or tongue soreness
- Headaches
- Pale or yellowish skin
- Heart palpitations
Best B-complex vitamin supplements of 2024
Vitamins are included in a B complex, which can be helpful if you have a higher nutrient requirement, are vegetarian or vegan, or have a medical condition that makes it difficult for your body to absorb nutrients. The items that we recommend the most for your consideration based on our analysis and experience are thoughtfully presented in the comprehensive list below:
- Nutrilite Vitamin B Dual Action: Nutrilite Vitamin B Dual Action, a dietary supplement distributed by Amway, is formulated to provide a comprehensive blend of all eight essential B vitamins. This innovative product features a bi-layer tablet design, incorporating advanced dual-action technology for optimized delivery of the vital nutrients.

Additionally, this Super B-Complex has 167 percent of the recommended daily intake of vitamin C, an essential antioxidant that supports immune system function.
- Thorne Research B-Complex #6: We would not advise pregnant women or those who are childbearing age to take this supplement because, although it contains sufficient amounts of the majority of B vitamins, its folate content is somewhat below the daily necessary amount. Moreover, it can be noted that Thorne’s B-Complex 6 contains higher niacin than the upper intake level (UL) that is advised. But Thorne makes sure to carefully craft their supplements, and the niacinamide form of niacin used in this supplement hasn’t shown any negative effects until much higher doses than what’s included in this supplement and beyond the upper limit.
- Garden of Life Vitamin B Complex: A great choice if you value taking supplements made from whole foods is Garden of Life Vitamin B Complex. Garden of Life B complex supplement contains different amounts of all eight B vitamins, from 113 percent to 5542 percent of your daily requirements. Organic broccoli and spinach are among the whole food blends that Garden of Life supplements are made from, unlike many other supplement brands that do not disclose the source of their vitamins.
- Nordic Naturals Vitamin B Complex: Not only is this supplement vegan-certified, but it might also be a great option for vegetarians or vegans. The majority of B12 in food comes from animal sources, and only about 1% of the B12 we get from supplements is absorbed by our bodies. For this reason, nutritional experts advise vegetarians who consume dairy and eggs to take this amount of vitamin B12 a few times a week, and vegans to supplement with more than 10,000 percent of the daily value of the vitamin every day. This specific dosage of vitamin B12 is provided by Nordic Naturals B-complex.
FAQs
In this part, let’s take a look at a few commonly asked questions by the users.
Should you stop taking vitamin B if your urine is yellow?
No, if you take vitamin B supplements, yellow urine by itself isn't always a reason for alarm. This is particularly true in the case of bright yellow pee.
Is vitamin B complex the same as vitamin B12?
Despite the fact that vitamin B12 is one of the vitamins included in a B-complex supplement, vitamin B complex and vitamin B12 are not the same.
Is it okay to take B complex every day?
Taking B complex daily is generally considered safe and well-tolerated by the majority of individuals who incorporate it into their daily routine. This is because B vitamins are water-soluble, which means that your body excretes them through urine rather than storing any excess.
When should you take vitamin B complex?
B vitamins and other water-soluble vitamins need enough water to be absorbed to their full potential. As such, it's usually advised that you take this kind of supplement with a glass of water and an empty stomach.
should you get vitamin B complex injection?
Most people do not require a vitamin B complex injection if they consume enough vitamin B through a varied diet.
Summary
A diverse, well-balanced diet full of naturally high-B vitamin foods—like leafy greens, nuts, beans and legumes, whole grains, lean protein, mushrooms, and eggs—will provide you with all you need to maintain your health. Since there isn’t much evidence to support any health benefits from taking large doses of B vitamins, you don’t need to do so if your body doesn’t naturally lack them. It is important to be mindful of your individual nutritional needs before considering any unnecessary supplements.
When taken as prescribed, a B-complex supplement is usually safe for consumption. But only take B vitamins in extremely high doses under a doctor’s supervision. These supplements can be purchased online from various brands, or they can be found in drug or health supply stores.
