How are we different?

Our Bioactive B Complex Sensitive is specially designed to prevent overmethylation while supplying the entire B complex (except vitamin B9). It does not contain folate, betaine or any methylated B vitamins; vitamin B12 is included not as methylcobalamin, but rather as adenosylcobalamin, while folate and betaine are completely omitted due to their strong stimulating effect on the methylation cycle.

In addition to the B vitamins, this complex also includes the important cofactors CDP-choline (formerly vitamin B4) and myo-inositol (formerly vitamin B8), as well as a special mixture of three vegan amino acids (either pharmaceutical grade or derived from fermentation): taurine, L-glycine and L-glutamine.

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.

Effects

B Vitamins

The B vitamin group includes eight water-soluble essential nutrients: vitamins B1, B2, B3, B5, B6, B12, biotin and folic acid. Unlike many vitamins, B vitamins cannot be stored in the body over a long period of time and must therefore be obtained daily through food. The only exception is vitamin B12, which can be stored in the liver.

It is crucial to ensure a balanced intake of all B vitamins due to their interdependent effects, but this is sometimes difficult to achieve due to their wide distribution across all food groups; only a very balanced diet can provide all B vitamins in sufficient quantities. Indeed, large nutrition studies consistently reveal clear gaps in their supply.

The Seven B Vitamins in B Complex Sensitive

  • Thiamine (B1) is involved in energy production as well as the normal functioning of the nervous system and brain.
  • Riboflavin (B2) plays a role in energy production, the reduction of fatigue and in maintaining healthy skin and mucous membranes as well as in the protection of cells and DNA against oxidative stress.
  • Nicotinamide (B3) contributes to the regulation of energy and fatigue and is needed for the function of the nervous system, brain, skin and mucous membranes as well as being involved in serotonin and melatonin synthesis.
  • Pantothenic acid (B5) plays a role in energy production in the mitochondria and is required for the synthesis of protein, cholesterol, steroid hormones and neurotransmitters as well as for the metabolism of vitamins A and D.
  • Pyridoxine (B6) contributes to erythropoiesis and supports energy metabolism, hormone activity and the immune and nervous systems as well as playing a crucial role in amino acid metabolism.
  • Biotin (B7) contributes to the maintenance of normal skin, mucous membranes and hair as well as to the normal functioning of energy metabolism, the nervous system and macronutrient metabolism.
  • Folic acid (B9) plays a role in cell division, blood formation and amino acid and homocysteine metabolism as well as being essential for healthy pregnancies.
  • Vitamin B12 (cobalamin) is required for erythropoiesis and for building DNA and proteins.

Important Cofactors in B Complex Sensitive

There are several vitamin-like nutrients that work together with the B vitamins as cofactors. Due to their close interaction, these compounds were considered B vitamins themselves until recently.

  • Choline (formerly vitamin B4) is part of acetylcholine, one of the most important neurotransmitters in humans, and supports fat and homocysteine metabolism as well as healthy liver function.
  • Inositol (formerly vitamin B8), part of the cell membrane, is a precursor of many chemical messengers and plays an important role in cell metabolism as a secondary messenger.

The Amino Acids in B Complex Sensitive

In addition to the B vitamins, this complex supplies the three important amino acids taurine, L-glycine and L-glutamine. These amino acids are required for the synthesis of glutatione, a tripeptide and the body's central antioxidant, from cysteine (from taurine), L-glutamine and L-glycine.

Health Benefits of B Vitamins

According to the European Food Safety Authority (EFSA), B vitamins contribute to:

  • Maintaining normal skin and mucous membranes
  • Maintaining normal hair
  • Maintaining normal cognitive function
  • Normal macronutrient metabolism
  • Normal energy metabolism
  • Normal functioning of the nervous system
  • Normal heart function
  • Maintaining normal iron metabolism
  • Maintaining normal red blood cells
  • Protecting DNA, proteins and lipids from oxidative stress
  • Cell division
  • Maintaining normal cysteine synthesis
  • Maintaining normal amino acid synthesis

Dosage

Recommended Dosage

Take 1 capsule daily with food and 200ml water.

Daily Requirements

The official daily requirement (NRV) for each B vitamin can be found below:

  • 1.1mg vitamin B1
  • 1.4mg vitamin B2
  • 16mg vitamin B3
  • 6mg vitamin B5
  • 1.4mg vitamin B6
  • 50µg biotin
  • 200µg folate
  • 2.5µg vitamin B12

Daily Cofactor Requirements

There are no official requirements for choline, inositol or betaine. All three can be synthesised in the body, so many people cover their daily needs endogenously. The following recommendations for dietary supplementation are stated in the literature:

  • Choline: 400mg (EFSA)/550mg (DGK)
  • Inositol: 2,000mg
  • Betaine/TMG: 500mg–2,000mg

Food Supplement

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

Storage

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