B Vitamins: Your Secret To Good Skin Health

What is Vitamin B Complex?

When we look in the mirror as part of our daily skincare routine and spot a new blemish, wrinkle, or dull patch of skin, most of us reach for an appropriately marketed beauty product without much thought. We may know this product treats acne and that one smooths wrinkles, but we arent necessarily sure why, or how, they do it. And we would hardly ever think to eat or drink something to treat our skin problems.

Perhaps its time to rethink that approach. Our skin is the bodys largest organ, and its affected by everything we put on it, as well as everything we ingest. Remedying poor skin requires us to treat not only our symptoms but the root causes as well, and that begins with good nutrition.

B vitamins in particular support skin health in a multitude of ways, making their inclusion in your daily regimen whether through diet, supplements, personal care products, or a combination of the three an effective and safe way to treat skin issues.

May Support Bone Health And Prevent Osteoporosis

Maintaining adequate vitamin B12 levels may support your bone health.

One study in more than 2,500 adults showed that people with a vitamin B12 deficiency also had lower than normal bone mineral density .

Bones with decreased mineral density can become delicate and fragile over time, leading to an increased risk of osteoporosis.

Other studies have also shown a link between low vitamin B12 levels and poor bone health and osteoporosis, especially in women (

10 ).

A study involving 5,000 women aged 40 or older concluded that supplementing with vitamin B12, along with folic acid and vitamin B6, may reduce this risk .

The group receiving these supplements for seven years had fewer cases of macular degeneration, compared to the placebo group. The risk of developing any form of the condition was 34% lower, while it was 41% lower for more severe types .

Ultimately, further studies are needed to fully understand vitamin B12s role in promoting vision health and preventing macular degeneration.


Maintaining adequate levels of vitamin B12 decreases homocysteine levels in your blood. This may help prevent the development of age-related macular degeneration.

How Can You Tell If Youre Deficient

As we just mentioned, most people can get the recommended amount of B vitamins through diet since they are found in a wide variety of foods. However, its still possible to be deficient despite eating healthy.

The following symptoms might indicate youre not getting enough B vitamins:

  • Abdominal Cramps
  • Peripheral Neuropathy
  • Migraine Headaches

Make sure to consult your doctor if you think you may be deficient in B vitamins. They can help determine whats causing your symptoms and, if needed, run the necessary tests as well as recommend ways to increase your B vitamin intake.

  • Those with a poor, low calorie diet
  • Aging and other conditions that impact food intake

Your doctor can order a simple blood test to diagnose a deficiency. As you can see from these groups, anyone who is not eating a well balanced, adequate calorie diet may benefit from a vitamin B complex supplement.

Helps With Red Blood Cell Formation And Anemia Prevention

Vitamin B12 plays a vital role in helping your body produce red blood cells.

Low vitamin B12 levels cause a reduction in red blood cell formation and prevent them from developing properly .

Healthy red blood cells are small and round, whereas they become larger and typically oval in cases of vitamin B12 deficiency.

Due to this larger and irregular shape, the red blood cells are unable to move from the bone marrow into the bloodstream at an appropriate rate, causing megaloblastic anemia .

When youre anemic, your body doesnt have enough red blood cells to transport oxygen to your vital organs. This can cause symptoms like fatigue and weakness.


Vitamin B12 is involved in red blood cell formation. When vitamin B12 levels are too low, the production of red blood cells is altered, causing megaloblastic anemia.

What Happens If You Get Too Much Vitamin B Complex

Youre unlikely to get too much vitamin B complex from your diet. Thats because B complex vitamins are water soluble. That means they arent stored in your body but are excreted in your urine daily.

Youre also unlikely to get too much vitamin B if youre taking any supplementation as directed.

That said, as with most supplements, its possible to consume too much at once especially if youre taking a supplement without receiving a deficiency diagnosis from your doctor.

When consumed in excess, a few different B vitamins can have specific side effects. For instance:

  • Vitamin B6. Too much B6 may lead to peripheral neuropathy, which is a loss of feeling in the arms and legs.
  • Folate or folic acid. Too much of this vitamin can cover up the symptoms of a vitamin B12 deficiency, which can eventually lead to nervous system damage.
  • Niacin. Too much niacin may cause skin flushes. Long-term excessive use may lead to liver damage.

While there isnt enough research to say exactly what will happen if you consume too much B complex, more is not necessarily better, especially over the long term.

Detecting Vitamin B Deficiency

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

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.

B Vitamin Deficiencies In Developed Societies

A general assumption tends to be made that the populations of developed countries have adequate nutrition, and are therefore free from deficiencies in essential micronutrients. In order to encourage adequate nutrition, governments typically define a set of dietary reference intakes or similar for individual nutrients. These always include something akin to the recommended dietary allowance, or RDA. These government figures describe the minimum daily intake of the specific nutrient that is considered to be sufficient to meet the nutritional requirement of the majority of the healthy population. However, meeting the requirements in this context typically refers to simply preventing chronic, nutrition related diseases or a disease state related to a specific deficiency of that nutrient .

Vitamin B Complex Dosage & Side Effects

Vitamin B Deficiency: Symptoms, Causes, Sources, Treatment || Vitamin B Rich Foods || Practo

Because vitamin B complex vitamins are water soluble, they are not stored in our body and typically an overdose is not a concern.1 However, you may experience side effects of very large doses of any particular vitamin or supplement.

For example, starting a Niacin supplement can cause flushing of the skin, and pantothenic acid can cause an upset stomach.6,7

The following list shows the amounts of each B vitamin needed daily for adults keep in mind that we obtain a lot of this amount from food, so a supplement need not contain more than these amounts:

  • B1 Thiamin: 1.1-1.2 mg per day2
  • B2 Riboflavin: 1.1-1.3mg per day 3
  • B3 Niacin: 14-16mg per day4
  • B5 Pantothenic acid: 5mg per day5
  • B6 Pyridoxine: 1.2 1.3 mg per day 6
  • B7 Biotin: 30 mcg per day of biotin7
  • B9 Folate: adults 400mg daily and pregnant women 600mg, but not more than 1000mg8
  • B12 Cobalamin: 2.4mg per day9

Two items to note: there is an established upper limit for folic acid , meaning more than this amount can be detrimental to health.8 B12 is one vitamin that is commonly supplemented alone because it is not always well absorbed from its food sources.

For this reason, its available in several different oral supplement forms, as well as a prescription strength injection.11
