Vitamin B Complex

Alongside the better-known B vitamins, there are three that sometimes get overlooked: Vitamin B4 (choline), B8 (inositol) and B10 (para-aminobenzoic acid). They aren’t officially part of the “essential” eight, but they still play useful roles in cell function, mood, and metabolism. Some advanced B Complex formulas include them to cover every possible nutrient in the B family.

Vitamin B Complex is a group of eight essential B vitamins – B1, B2, B3, B5, B6, B7 (Biotin), B9 (Folate) and B12. They work together to support energy, metabolism, the nervous system and overall wellbeing.

Each B vitamin has its own role, but they often work best together. For example, some support energy release, while others help make red blood cells or maintain mental performance. A B Complex ensures you’re covering all bases at once.

Taking B vitamins on an empty stomach can cause nausea because they’re water-soluble and are absorbed quickly, which can irritate the stomach lining when there’s no food to buffer them. If this is a problem for you, having them immediately after your main meal of the day reduces stomach irritation and prevents queasiness.

The recommended daily amounts for each B vitamin vary depending on your age, whether you’re male or female, if you eat meat, or if you’re using more than normal - for example when you’re pregnant or when you’re going through physical or mental stress. There are also significant variations in each person’s requirements, depending on their genetic profile. Researchers are just beginning to discover that some people’s bodies use various B vitamins far more efficiently than others. Because B vitamins are water-soluble and quickly excreted, the best quality supplements typically contain far higher doses than the daily minimum - to ensure absorption of adequate amounts and support even in times of greater need - such as stress, age, diet, or specific health conditions.

“Methylated” forms of vitamins, such as methylfolate (B9) or methylcobalamin (B12), are the “active” versions your body can use straight away. Some people have genetic variations (like MTHFR) that make it harder to process standard folic acid or cyanocobalamin, so methylated forms can be more effective for them.

Stress increases the body’s demand for B vitamins, especially B5, B6 and B12, which are involved in energy metabolism and the production of stress-related hormones and neurotransmitters, including cortisol and adrenaline. This means it’s easier to become depleted in B vitamins during stressful times - this is why we often feel deeply exhausted and fatigued after prolonged stress. Taking a high-dose vitamin B complex helps support the body’s natural ways of coping with stress, bolsters mental resilience and reduces the risk of fatigue.

B vitamins help your body turn food into usable energy by supporting metabolism. Without enough of them, your cells can’t efficiently release energy from carbohydrates, fats and proteins, which may leave you feeling tired or run down.

Yes. Vitamins B1, B2, B3, B6, B12 and Biotin all support the normal functioning of the nervous system. Vitamin B5 also contributes to mental performance by helping produce neurotransmitters, the brain chemicals that carry signals between nerve cells.

Folate, B6 and B12 help regulate homocysteine levels in the blood. High homocysteine is linked with cardiovascular concerns, so keeping it balanced supports healthy circulation and heart function.
