Detecting Vitamin B Deficiency

What is Vitamin B Complex?

If you experience any of the following symptoms, you may have a vitamin B deficiency.

  • Weight loss

Regular occurrence of these symptoms may be an indicator of vitamin B deficiency. To overcome the same, you need to consume B complex vitamin supplements or foods that may help you fulfil your requirements. However, before we move to the foods, let us understand the components of B complex vitamins.

How Much Vitamin B Complex Is Safe To Take In A Day

A vitamin B complex supplement typically contains riboflavin, pantothenic acid, folic acid, niacin, biotin, thiamin, vitamin B6 and vitamin B12. Most people get enough from foods high in B vitamins.

However, people with restricted or poor diets or those with certain medical conditions may benefit from taking a vitamin B complex supplement. Always talk to your doctor to determine if supplementation is appropriate in your situation.


While personal vitamin needs vary from person to person, you shouldn’t get more than 100 percent of the RDA from your vitamin B complex.

Tolerable Upper Intake Levels

The tolerable upper intake level is the maximum amount of a vitamin or mineral you can take without running the risk of experiencing unpleasant side effects.

Although it may be beneficial to take more than the recommended dietary allowance of certain vitamins, you should never take more than the tolerable upper intake level unless specifically instructed by a doctor to do so.

Some B vitamins, such as vitamin B12, thiamin, biotin, pantothenic acid and riboflavin, don’t have tolerable upper intake levels. This means that you’re unlikely to experience adverse reactions when taking these vitamins, even if you take high doses.

However, folate, vitamin B6 and niacin do have a tolerable upper intake levels. Getting more than 1,000 micrograms a day of folate, 35 milligrams a day of niacin or 100 milligrams a day of vitamin B6 may cause unpleasant side effects. Avoid taking a vitamin B complex supplement that contains more than these amounts.

Can You Take B Complex And B12 Together

Taking both isn’t the best idea. This isn’t because it’s dangerous ââ¬â instead, it’s just because it’s unnecessary. Your B complex supplement probably already has vitamin B12, so there’s no need to take a separate pill, explains the Mount Sinai Health System.

But if you do take both supplements, you don’t have to worry about overdosing on B vitamins. If you take too much vitamin B12 via supplements, your body will use the amount that it needs and eliminate any excess amount through your urine, according to the Mayo Clinic.

But extremely high levels of vitamin B12 may bring on some mild side effects, including headaches, fatigue and nausea.

Produces Red Blood Cells

What are the side effects of Vitamin B Complex?

Some B vitamins, particularly vitamin B12, play an essential role in the formation of red blood cells. Healthy red blood cells are needed to transport oxygen to every part of the body, and when there’s a vitamin B12 deficiency, the body will struggle to produce enough red blood cells, often leading to anemia.

Vitamins B2 and B9 are also needed for red blood cell production and growth. While vitamin B5 plays a role in red blood cell production, it also helps reduce the amount of cholesterol produced by the body. And vitamin B6, which is required for more than 100 different enzyme reactions in the body, aids in the formation of hemoglobin, which also allows red blood cells to carry oxygen through the blood.

B vitamins involved: B2, B5, B6, B9, B12

Supplements can provide you with a combination of B vitamins and other nutrients. But you can also get B vitamins from food. The top sources of B vitamins include the following, per the University of Wyoming:

  • Fortified grain products, such as fortified cereal and fortified bread
  • Nuts and legumes
  • Dairy products
  • Meats, especially organ meat
