Top 7 Best Vitamin B Supplement Reviews

While vitamin B is big news for keeping you feeling great, it’s also proven to have real impacts on longevity. Research studies have shown that the prevalence of people who have heart attacks and certain types of cancer is significantly less among those with higher vitamin B intakes. And then there’s this fun fact: A study on the long-lived Japanese island of Okinawa found that the further people live from their optimal blood level of vitamin B, the more likely they are to die at an earlier age!

7. Thorne Research – B-Complex

Primary Supplement TypeVitamin-b
BrandThorne Research
Item FormCapsule
Specific Uses For ProductNervous System, Cellular Energy, Metabolism,Energy
Age Range (Description)Adult

Thorne’s B-Complex #12 contains an optimal balance of B vitamins, with extra B12 and folate. Unlike many multi-B formulas, B-Complex #12 contains the active forms of the B vitamins for optimal utilization by the body.

The potential for adverse impacts on neurological health (the health of the brain and nerves) is increasing and becoming more prevalent because of increased lifespans, environmental toxicity, and poor diet with subsequent nutrient deficiencies.

It is believed that mitochondrial sufficiency is at the foundation of brain and nerve health. But the mitochondria, the cell’s energy-producing powerhouse, are also a significant source of free radical production, even in healthy individuals. The aging process, poor diet, and environmental toxins can stress the body’s built-in antioxidant system, making it less capable of quenching free radicals, such as those produced in the mitochondria.

The B vitamins help mitigate these stressors.* Thorne’s B-Complex #12 helps maintain good neurological health.

Well-Researched Benefits

The B vitamins in Thorne’s B-Complex #12 support mood, cellular energy production, and brain and nerve health.

Designed for Sensitivities

The ingredients in B-Complex #12 are not derived from yeast like many other B vitamin supplements

Greater Absorption

The bioactive forms of the B vitamins in each capsule ensures you will get the most bioavailable vitamin B complex available.

Unique Formula

Unlike many multi-B vitamin supplements, B-Complex #12 contains the active forms of several of the eight water-soluble B vitamins.

Sourcing Exceptional Ingredients

We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility – and ultimately better health.

Four Rounds of Testing

We perform four rounds of testing for each product we manufacture – far above the industry standard. Thorne has invested in two state-of-the-art in-house laboratories that enable us to conduct four rounds of testing, including raw material testing, in-process batch testing, finished product testing, and expiration date stability testing for each lot of product that we manufacture.

Manufacturing the Right Way

We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified.

Thinking Sustainably

We’re thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards.

B Vitamins in Different Forms

Most complexes will include eight vital B vitamins that can help with energy levels and cell metabolism. Following is some further information about each B vitamin.

B1 (Thiamin)

Thiamin can aid in the digestion of meals and the release of energy for utilization. It can be found in peas and nuts in nature.

B2 (Riboflavin)

Riboflavin aids in the release of energy from food and may benefit your eyes, skin, and neurological system. Vitamin B2 is found in mushrooms, yogurt, milk, and eggs. (3)

B3 (Niacin)

Niacin can improve your neurological system and skin, as well as aid digestion by helping your body to extract energy from food. Niacin is found in wheat flour, eggs, fish, and meat. (4)

B5 (Pantothenic Acid)

Pantothenic acid can also assist the body in releasing the energy provided by food. Pantothenic acid can be found in avocados, mushrooms, eggs, poultry, and cattle. (5)

B6 (Pyridoxine)

Pyridoxine may aid in the storage of energy as well as the formation of the oxygen-carrying molecule haemoglobin. Pyridoxine can be found in oats, soy beans, bananas, peanuts, pork, chicken, and turkey. (6)

B7 (Biotin)

Biotin aids in the production of fatty acids in the body. Nuts, seeds, legumes, and liver all contain it. (7)

Folic Acid and Folate

Folic acid is a human-made type of folate that aids in the formation of red blood cells. Broccoli, leafy greens, peas, chickpeas, and kidney beans are high in folate. (8)


Vitamin B12 may aid in the release of energy from food as well as the formation of red blood cells. Milk, eggs, cheese, seafood, meat, and nutritional yeast all contain it. (9)

B Vitamin Advantages

Vitamin B can assist your body to acquire energy from food while also enhancing cellular activities in all of its forms. Below, we go over further specifics.

Levels of Energy

Vitamin B, particularly B6, pantothenic acid, thiamin, riboflavin, and B12, can aid in the digestion of meals. Digestion is the process of obtaining energy from food in order to fuel your body’s processes. Vitamin B can help maintain and improve your body’s energy levels by helping to make more energy accessible to you after eating by assisting with digestion and food breakdown. (10)

Functions of Cells

B vitamins such as folate and biotin can aid in a variety of cellular activities that aren’t always related to digestion. Biotin may help in the creation of fatty acids, while folate (or folic acid in supplement form) and B12 may aid in the development of red blood cells. (11) Vitamin B6, commonly known as pyridoxine, can aid in the formation of hemoglobin. (12) All of these cellular activities can assist in keeping your body in the shape it need to function properly.

When Should I Take a B Complex Vitamin?

Take your vitamin B complex capsule, tablet, or gummy with a meal, according to many vitamin B complex supplements. You might want to take your supplement with a morning meal so that you don’t get an energy boost right before bedtime because it can help with energy generation through digestion.

How We Selected The Most Effective Vitamin B Complexes

We wanted to make sure we were bringing you the best of the best with so many vitamin B complexes to select from, so we weighed dosage, purity, affordability, and more while compiling this list.


One of the most significant variations between vitamin B complex choices is dosage quantities. Because not all brands include the same levels of each vitamin, it’s critical to read the nutrition facts carefully to ensure that they match the requirements of your specific diet.

There isn’t a set of vitamin B dosages that any of these products follow, and there isn’t one set for the entire market. Knowing what daily percentage gain you want to achieve with each vitamin can help you find the optimal selection. We’ve included alternatives in a variety of dosages so that no matter what you’re looking for, you’ll find it on this list.


When purchasing any supplement, it is critical to understand what is contained within each bottle. Labdoor is a fantastic place to go for impartial third-party testing, and it can tell you how accurate each nutritional label is. It’s also a good idea to double-check that the recipe for the complex doesn’t contain any superfluous or unnatural elements. We listed a product that has been third-party tested here to save you some time.

Features Not Included

Almost every vitamin B complex product contains some of each of the eight B vitamins. However, to set themselves apart from the competition, some will use additional components such as vitamin C or other natural substances. This could be appealing depending on your dietary requirements. To satisfy a variety of consumer needs, we’ve included both plain B complexes and B complexes with extra components on this list.


Vitamin B complex is often found in the form of capsules or tablets. If you have trouble swallowing tablets, it is also available as a gummy. Because the nutritional value of these goods does not alter depending on the form in which they are delivered, determining which form is best will ultimately come down to personal preference or lifestyle. As a result, we’ve included a range of forms so you can pick one that suits your needs.


Divide the total cost of each supplement by the number of servings in the container to get the price of a product. This will provide you with a particular value for each serving, allowing you to compare items directly. This list has a wide range of pricing, so you should be able to find something to fit any budget.

What to Think About When Purchasing Vitamin B Complexes

Vitamin B complex supplements typically contain eight different forms of B vitamins, each of which has a different role to play in the regulation of various biological activities. While most people obtain enough of these vitamins from a well-balanced diet, some people may benefit from supplementing. This includes pregnant women and those who maintain a strict vegan diet (particularly if they dislike nutritional yeast). Consider some of these crucial aspects before choosing if a B complex is an appropriate decision.

Circumstances of Life

Because energy levels can be difficult to control while pregnant, and because folate and folic acid might help reduce the chance of certain birth abnormalities, you might want to discuss taking a vitamin B complex with your doctor.

Diet Right Now

Most necessary types of vitamin B can be found in vegan and vegetarian foods. However, if you’re a vegan who doesn’t enjoy nutritional yeast, which is usually supplemented with B12, you can find it difficult to incorporate all of the required B vitamins into your diet. In that situation, you might want to consider taking a supplement.

Even if you aren’t vegan if you suspect you aren’t receiving enough B vitamins in your diet or are experiencing fatigue, consult your doctor to determine if a B complex is good for you.

Form and Taste

Some people have a hard time swallowing capsules. Tablets are too much for others. Others are concerned about the extra calories and sugar that gummies may contain. Regardless of whose group you belong to, there are a few options available to you. The majority of vitamin B complexes come in capsule form, although there are a few gummy and tablet varieties as well. Greens powder with B vitamins is sometimes available. Before diving into your alternatives, decide on your form/flavor priorities.

Final Word

B group vitamins do some pretty amazing stuff in the body. They help convert carbohydrates into energy, aid in brain function, contribute to digestion, and help red blood cell development. Plus key B vitamins are essential for keeping the immune system strong and preventing anemia. While deficiencies aren’t extremely common in North America, it’s worth adding one of these supplements to your diet for their antioxidant properties and overall health benefits. Many brands on this list also offer a variety of B vitamin options—stick with a few of these suggestions if you can’t find one that works for you.
