Vitamin B12: the Fuel for a Healthy and Vibrant Life!

Imagine a potent nutrient that keeps your metabolism firing on all cylinders and plays a vital role in numerous functions of your body. This is Vitamin B12. It not only safeguards your DNA, but also elevates your immunity, mood, focus, and memory, acting to reduce stress and migraines. But that’s not all – Vitamin B12 is also a crucial ally in the absorption of other essential nutrients, impressively boosting your well-being.

Bid farewell to days of low energy and say hello to optimal health! Vitamin B12 is like a conductor leading the symphony of your body, ensuring your energy is always at its peak. Furthermore, it plays a critical role in maintaining bone health and contributes to the proper functioning of your gut, warding off unpleasant issues like bloating, constipation, and diarrhoea.

It is a vitamin produced by bacteria in the intestines and is directly linked to gut health, as it is a key player in the nutrient absorption process. When Vitamin B12 consumption is insufficient or deficient, it could be associated with an increased risk of infections and neurodegenerative diseases, as brain functions may not operate correctly, potentially hastening the onset of conditions like Parkinson’s, Alzheimer’s, and other serious brain-related problems.

Additionally, Vitamin B12 is closely connected to immunity. As a nutrient that assists in red blood cell formation and cell repair, when the immune system is under attack from environmental toxins or poorly digested food, the defence mechanism may react irregularly, failing to adequately protect the body.

Furthermore, immunity can be compromised due to damage inflicted on intestinal cells. This situation can harm and breach the intestinal wall cells due to the poor quality of ingested foods, often including fast food and/or processed items. Such foods hinder the absorption of Vitamin B12 as they lack healthy nutrients in their composition, thus triggering infections and negatively impacting the body’s functionality.

So, how can you incorporate Vitamin B12 into your dietary routine?

To ensure adequate consumption that contributes to health and quality of life, foods rich in Vitamin B12 should be included in your daily intake (meat, eggs, fish, and pork, among others). But what about a vegetarian diet? Even with minimal consumption of animal-derived foods, achieving desired levels of Vitamin B12 is possible through a vegetarian diet. In such cases, consider incorporating algae like chlorella, spirulina, and nori seaweed, and always evaluate the potential for appropriate vitamin supplementation.

Ideally, include a source of animal protein in one meal per day, complemented by other natural and healthy foods like fruits and vegetables to ensure you receive the necessary vitamin intake.

How do I know if I have the right levels of Vitamin B12 in my body to function well?

You can do a blood test and find out the levels of vitamin B12 in your body. Remember, excess vitamins can be toxic and also cause adverse effects on your body.

If you want to check your B12 levels or you are concerned about any symptoms mentioned above, seek help from a registered dietitian. Find more information here. 

Vitamin Deficiencies: What are the Main Signs and Symptoms?

Vitamin deficiency signs and sympotoms

Vitamins Explained by a Nutritionist in London

Vitamins are called essential micronutrients because they are necessary to the body in small amounts, but they are essential for the maintenance of good health.

The body does not store most of the vitamins. The deficiency of these vitamins usually develops in weeks to months. Therefore, people should consume them regularly. Vitamins A, B12, and D are stored in significant amounts, especially in the liver. Vitamins A and D are also stored in adipose cells (fat cells).

Some vitamins (A, D, E and K) are lipo-soluble which means they are absorbed in fat and we store them. Others, like vitamins B and C, are water-soluble. B vitamins include biotin, folate, niacin, pantothenic acid, riboflavin (vitamin B2), thiamine (vitamin B1) and vitamins B6 (pyridoxine) and B12 (cobalamines). The water soluble vitamins excess usually are efficiently eliminated by our urine.

The state of nutritional deficiency occurs when the intake of nutrients does not correspond to the needs for optimal health of an individual. With this, there are some signs and symptoms that we should be aware of.

Some examples of nutritional deficiencies of the major vitamins:

Vitamin A

Vitamin A is related to immune functions, skin health, vision, reproduction and cellular communication.

Signs and symptoms of deficiency: increased risk of infections; night blindness; dry skin and hair; recurrent conjunctivitis; colour blindness; infected and ulcerated eyes; macular degeneration and acne.

Vitamin C

Vitamin C is a powerful antioxidant and prevents various diseases.

Signs and symptoms of deficiency: Dry skin, dry or brittle hair, bleeding gums, delayed wound healing, immune problems – colds and recurring flu, tooth loss, anemia, nose bleeding, bruising, muscle weakness and fatigue.

Vitamin E

Vitamin E is an antioxidant that protects cells and prevents muscle weakness and neurological problems.

Signs and symptoms of deficiency: Eye problems such as retinopathy and cataract, skin problems such as acne, wounds, scars and stretch marks; mild anemia; fertility problems and abnormalities in brain function.

Vitamin B12

This vitamin plays a key role in the functioning of the brain and nervous system, as well as in the formation of red cells.

Signs and symptoms of deficiency: Numbness and twinges in the hands, legs or feet; lack of balance; anemia; swelling or inflammation of the tongue; jaundice (yellowish skin); weakness; paranoia and hallucinations; lack of air; cognitive difficulties and loss of memory and loss of vision.

Complex B Vitamins

Other B vitamins include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B7 (biotin) and folate. One of their very important functions is to aid in the metabolism of nutrients in our body.

Signs and symptoms of deficiencies: vision problems; fatigue; adrenal insufficiency; oedema (fluid retention); pallor and dandruff.

Vitamin D

Vitamin D plays an important role in the immune system and promotes bone growth.

Signs and symptoms of deficiency: overweight or obesity; depression; bone pain; low mineral density in bones; osteoporosis (porous and brittle bones); osteomalacia (softening of bones); rickets (a disease that causes severe bone deformities) and muscle weakness.

Other nutritional deficiencies and risks

There are other symptoms related to nutritional deficiencies not only of these vitamins but of minerals as well, so it is ideal that everyone undergoes periodic nutritional screening throughout life by a nutritionist to perform nutritional assessments regularly.

The consumption of large amounts (megadoses) of certain vitamins (usually supplements), without the supervision of a professional, can have harmful effects.

In order for these deficiencies to be identified, it is important to do a blood tests for vitamins.

At Raquel Britzke Clinic in London, we perform blood tests for the main vitamins (A, C, E, B1, B2, B6, B12, and folate). If you are concerned and have one or more of the symptoms above seek professional advice.
