Signs You May Need More B Vitamins In Your Diet

3 minutes to read

Unlike its term, Vitamin B Complex is pretty simple. The term B complex is commonly a mixture of eight B vitamins including Thiamin (B1), Riboflavin (B2), Niacin (B3), Pantothenic Acid (B5), Pyridoxine (B6), Biotin (B7), Folate/Folic Acid (B9) and Cyanocobalamin (B12).

Each play an essential role in maintaining good health. It is important to remember you should be able to get the B vitamins you need by eating a varied and balanced diet. 

In this blog we will highlight the symptoms of lack of vitamin B and the steps you can take to ensure you are getting your recommended daily intake.

Tiredness and Fatigue

If you’re missing out on vitamin B12, your body might respond with various signs and symptoms including fatigue. Vitamin B12 and Folate assist with healthy red blood cell production which carry oxygen to your vital organs so when you are deficient in these vitamins, it’s not uncommon to feel wiped out no matter how much you snooze. ¹

Vitamin B6, also known as pyridoxine, is another key vitamin that plays a role in storing energy from protein and carbohydrates in food as well as forming haemoglobin, the substance in red blood cells that carries oxygen around the body. ²

Tiredness is a common symptom amongst those who are lacking in B12, Folate & B6 so it’s important to ensure you are getting plenty of it through a varied diet. Good food sources for Vitamin B12 include meat, fish, eggs, dairy products, yeast extract and specially fortified foods. Vitamin B6 can include wholegrain cereals, vegetables and soya beans. Folate is found in small amounts of many foods. Good sources include broccoli, brussel sprouts, leafy green vegetables and peas. ³

Lack of Energy

To keep energy levels up, it’s important to eat a healthy balanced diet that’s full of energy sources. A common reason for a lack of energy could be because an absence of nutrients including Vitamin B1. Thiamin (Vitamin B1) breaks down and releases energy from food and like the other B vitamins, it also contributes to normal energy yielding metabolism. 

Common food sources of vitamin B1 include fortified breakfast cereal, enriched and whole-grain products (bread, breakfast cereals, rice, noodles, and flour), wheat germ, pork, trout, black beans, mussels, and tuna.

Muscle & Nerve Weakness

As playing an essential role in the production of our red blood cells, DNA and the nervous system, without vitamin B our bodies can’t work as well. Another sign that you may not have enough vitamin B in your body is muscle and nerve weakness. Muscle weakness occurs when your body doesn’t have enough vitamin B12 to make red blood cells, which transport oxygen throughout your body.

Weakened Immune System

If you’ve noticed that you’re often sick, feel fatigued or have other nagging symptoms you can’t figure out, it may mean your immune system is weakened. ⁴ Please reach out to a qualified doctor for a diagnosis or treatment.

Vitamin B6 is an essential vitamin needed to maintain normal brain development and keeping the immune system healthy. It plays a role in a wide variety of functions in the body and is extremely versatile, with involvement in more than 100 enzyme reactions including gluconeogenesis and glycogenolysis and immune function. ⁵

Good food sources of vitamin B6 include pork, fish, bread, wholegrain cereals, eggs, vegetables, soya beans, peanuts and milk. ⁶

Food supplements should not replace a balanced diet and healthy lifestyle, however if you sometimes struggle with your daily recommended intake of vitamins and minerals, VÖOST can help fill in the gaps.
