Vitamin Profile: Vitamin B12 | Mindful Healing | Mississauga Naturopathic Doctor

Making sure you get enough vitamins can be confusing at times.

There’s so many different types of vitamins, and then when you get to the “B” vitamins there’s even more variety.

For the last few months, we’ve been looking at the B complex of vitamins. The last one was on the benefits of vitamin B9, but today we’ve reached the end of the road.

It’s time to take a closer look at the last B vitamin in the list, vitamin B12.

Vitamin B12 is a water-soluble vitamin which can occur in some foods, but also may be taken as a supplement or sometimes even prescribed by a doctor, however it cannot be produced by the body.

It has a number of functions related to forming red blood cells, neurological functions, and synthesizing DNA.

Let’s take a closer look at some of the benefits of B12.

Benefits Of Vitamin B12

The list of benefits of vitamin B12 is impressive. The ones we’ll look at today are supported by science, and can have huge impacts on your life if you’re deficient in B12.

1. Helps Your Body Absorb Iron

Vitamin B12 can help facilitate the body’s absorption of iron.

Iron is critical for healthy growth, and deficiency of it results in anemia.

In infants, iron deficiency can result in premature birth, low birth weight and delayed development.

Iron deficiency has also been linked to low IQ and poor performance at school and work.

2. Supports Bone Health

A study of over 2,500 adults showed those with a vitamin B12 deficiency were also more likely to have a lower than normal bone mineral density.

Low bone mineral density can result in bones becoming delicate and fragile over time, and an increased risk of osteoporosis.

3. Can Help Fight Depression

A study from 2000 in the American Journal of Psychiatry showed a link between low B12 levels in depressed subjects.

Those with a vitamin B12 deficiency were 2.05 times more likely to be severely depressed than those with normal levels of B12.

4. Contributes To Red Blood Cell Formation

Vitamin B12 is critical for helping your body produce red blood cells.

Low B12 levels can result in reduced red blood cell production, and the ones which do develop may not develop properly.

When there is a B12 deficiency, red blood cells can become larger than normal, and oval in shape, instead of round.

This causes them to be unable to enter your bloodstream, which means you won’t have enough red blood cells to transport oxygen to your organs.

5. Helps Prevent Neural Tube Defects During Pregnancy

A 2009 article in the journal Pediatrics showed mothers of children with neural tube defects were more likely to have low B12 levels.

Those with concentrations of 250 ng/L or less were at the highest risk for these complications.

It is recommended that prospective mothers have vitamin B12 levels of at least 300 ng/L before becoming pregnant.

6. May Slow Cognitive Decline

In 2016, a study in the Journal of Alzheimer’s Disease showed that in people with mild cognitive impairment, treatment with B vitamins lowered the rate of clinical decline.

B12 may play a role in preventing brain atrophy and neuron loss, which are causes of dementia.

Other Benefits

Other benefits of vitamin B12 include:

● A reduced risk of macular degeneration, which is a disease affecting vision
● Improvement of mood and lessening symptoms of depression
● Increased energy levels
● Improved heart health
● Healthier hair, skin, and nails
