How are we different?

Vitamin B6 is present as a variety of different active compounds. Pyridoxine, which is the form that most manufacturers use, is not actually biologically active until converted by the body. We have therefore chosen pyridoxal 5'-phosphate (PLP) as the active ingredient in our formulation, the directly active coenzyme form of vitamin B6, which the body can use directly in all important metabolic pathways.

Our premium PLP is a pure, high-quality and vegan active ingredient with the highest possible bioavailability.

The only other ingredient is premium acacia fibre, cultivated without the use of plant protection products. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural, fibre-rich food. Our fair trade acacia gum is climate neutral and is sustainably cultivated to conserve resources.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Vitamin B6 (Pyridoxine)

Vitamin B6 (pyridoxine) is the precursor of pyridoxal 5'-phosphate (PLP), one of the most important coenzymes in humans. As an active coenzyme form of vitamin B6, PLP enables about 100 enzymatic reactions and plays a central role in the metabolism of amino acids.

Vitamin B6 supports the breakdown of homocysteine and contributes to the normal synthesis of cysteine, an amino acid which serves as a central building block of important compounds such as coenzyme A, creatine, glutathione and taurine.

Vitamin B6 is also involved in the synthesis of the neurotransmitters serotonin, noradrenaline, dopamine and GABA. In addition, by modulating the effect of testosterone and oestrogen, vitamin B6 makes an important contribution to normal mental function and a healthy nervous system through these steroid hormones.

The influence of vitamin B6 in the nervous system extends to the synthesis of important components of the cell membrane, including myelin, a protective nerve layer, as well as phospholipids and sphingolipids.

Vitamin B6 is also important for energy metabolism, as it is involved in the metabolism of protein and glycogen. Glycogen is a carbohydrate that serves as an energy store in cells.

Directly Bioactive Vitamin B6 in the Form of PLP

In the form of pyridoxine, vitamin B6 does not have any direct biological activity. It must first be converted by the body into bioactive pyridoxal 5'-phosphate (PLP), a coenzyme form of vitamin B6, in order to be metabolically active.

Health Benefits of Vitamin B6

According to the European Food Safety Authority (EFSA), vitamin B6 contributes to:

  • Normal energy metabolism
  • Normal protein and glycogen metabolism
  • Normal functioning of the nervous system
  • Normal immune system functioning
  • Normal mental function
  • Hormonal activity regulation
  • Reducing tiredness and fatigue
  • Normal red blood cell formation
  • Normal homocysteine metabolism
  • Normal cysteine synthesis


Recommended Dosage

Take 1 capsule (25mg vitamin B6 in the form of PLP) daily with 200ml water and a meal.

Daily Requirements

The requirement for vitamin B6 is between 1.2-1.8mg daily and increases according to protein intake.

Larger quantities of vitamin B6 are required by individuals who are pregnant, breastfeeding or of advanced age, during sports or stressful periods and with high-protein diets. Smoking and alcohol consumption, as well as many medications, further increase B6 needs. Moreover, this vitamin is very sensitive to heat and can be disintegrated during cooking or frying.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.

All eight essential B vitamins work together. Numerous metabolic processes in the body require them; they can only achieve optimal functionality if each vitamin is in sufficient supply. Therefore, in many cases, it makes sense to supplement these vitamins together.

Magnesium, iron and zinc support the effects of vitamin B6.
Vitamin B6 is particularly synergistic with folate and vitamin B12.
Vitamin B2 deficiency increases the excretion of vitamin B6.
Nicotinic acid (B3) acts as an antagonist in high doses.
Coenzyme Q10 and vitamin B6 work together synergistically.
Vitamin B6 works together with vitamin B12, folate and betaine/choline to break down homocysteine.
