How To Choose the Best Vitamin B Complex

Dosage

When taking a vitamin B complex, always follow the instructions for dosage indicated by the supplement. Recommended daily allowances vary depending on the person's age and other medical conditions. Always consult a primary care provider if you are unsure if a B complex vitamin is right for you.

Type

There are eight types of B vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). Each type of B vitamin has a distinct function. B1 can help turn the food you eat into energy and boost your immune system. B2 may prevent headaches and migraines and support other B vitamins in their functions. B3 can help you maintain a healthy cardiovascular system.

If you're feeling stressed, B5 can help your body produce hormones to help your body combat stress. B6 can assist in the communication between your brain and your cells. Looking for healthy hair, skin, and nails? B7 can help you keep those in good condition. B9 also may support your cardiovascular system by reducing your chance of heart disease and B12 can help you maintain your nerve health. Depending on your needs, you might choose a supplement that includes all eight B vitamins or a variation of a few.

Ingredients

Other than looking for the B vitamin varieties of your choice, you'll also see other ingredients. Some include other vitamins and minerals such as calcium, vitamin C, or zinc. You'll also see the ingredients used to make the capsules, which are often made out of vegetables. Silicon dioxide is also a popular ingredient since it is an anticaking agent. If you choose a gummy or liquid vitamin B complex, you'll see more ingredients used for flavoring or texturizing. Overall, it's always a good idea to look up any ingredients you don't recognize and to choose supplements with the fewest additives.

Benefits of Vitamin B Complex Supplements

Each B vitamin has its unique benefits, but overall having a combination of them or all eight could benefit body processes such as metabolism, energy levels, brain function, and cell metabolism. It is important to note that many foods contain B vitamins, so it's always a good idea to check with your primary care provider before taking any supplements since too much vitamin B can cause side effects.

FAQs About Vitamin B Complex


Is it OK to take vitamin B complex everyday?

Always consult with your doctor before taking any supplements, but generally if you're following the recommended dosage you can take one serving each day. Some vitamin B complex pills need to be taken with food, but some can be taken on their own.

What is the best time to take vitamin B complex?

Since these could impact your energy levels, it's recommended to take them earlier in the day, but the best time depends on your health and needs. Getting into a routine of taking it at the same time every day can help you establish the habit so you don't forget or second guess yourself.

How long does it take for vitamin B complex to work?

Research has shown that after two weeks people start to report feeling more alert. However, these claims are not backed by the FDA (Food and Drug Administration). Typically, if you're consistently taking a vitamin B complex supplement, you can take note of how you're feeling after a few weeks to see if you notice a difference in your overall health.
