Premium Bioactive Ingredients

  • Bioactive complex of choline and inositol
  • 250mg choline bitartrate and 250mg myo-inositol per capsule
  • Premium vegan raw materials of the highest quality
  • Choline was formerly known as vitamin B4 and myo-inositol was formerly known as vitamin B8

How are we different?

Our synergistic choline inositol complex contains only pure raw materials. Choosing the high quality available, we use myo-inositol, the most biologically available form of inositol, which naturally exists in 9 different forms, and choline bitartrate, a highly available form of choline.

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.


  • Premium active ingredients in their purest form
  • Sourced directly from the world’s best producers
  • Our select raw materials are the basis of all our formulations
  • Complete avoidance of all unnecessary additives and adjuvants
  • Exclusive use of valuable natural ingredients for additives
  • We voluntarily declare all ingredients
  • All extractions performed without the use of chemical solvents
  • Custom production when necessary, in order to achieve the highest possible level of purity
  • Independent laboratory testing available on product pages
  • Raw materials sourced only from premium suppliers who are committed to fair working conditions

Inositol is a vitamin-like compound that was previously known as vitamin B8 until it was discovered that the human body can produce it from glucose. Though this means that inositol is no longer considered a vitamin, it is still vital for important functions in the body.

Inositol exists in the form of 9 different isomers. All inositol compounds differ only in the spatial arrangement of their atoms. The two best-known inositol forms are myo-inositol and D-chiro-inositol. Inositol is mainly found in the brain, liver and kidneys.


Choline is an essential vitamin for many animals, and until it was found that the body can cover part of its requirements through its own synthesis using glutamine and ornithine, it was counted among the vitamins of the B-complex in humans. Today, although it is no longer called vitamin B4, choline is considered a semi-essential, vitamin-like substance.

Choline plays an important role in a variety of body functions. It is mainly found in the body in the form of phosphatidylcholine (lecithin) and acetylcholine. In fat metabolism, it supports the liver's enzyme system and is an important component of bile secretion. As a component of VLDL (very-low-density lipoproteins), it transports fat and cholesterol from the liver to other body tissues. Furthermore, choline functions as a methyl group donor. Just like betaine, vitamin B12, folate and S-adenosylmethionine, it helps regulate homocysteine levels.

Health Benefits of Choline

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

  • Normal homocysteine metabolism
  • Normal lipid metabolism
  • Maintaining normal liver function


Recommended Dosage

Take 2 capsules (500mg choline + 500mg inositol) daily with 200ml water and a meal.

Daily Requirements

There are no official guideline values for choline and inositol. These substances can be synthesised by the body, so many people can completely cover their daily requirements endogenously. The following recommendations for dietary supplementation are provided in the literature:

Choline: 400mg (EFSA)/550mg (DGK)
Inositol: 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.


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

In addition to the eight essential B vitamins (B1, B2, B3, B5, B6, B7, B9, B12), there are vitamin-like compounds, or vitaminoids, that work closely with the B vitamins as cofactors and were therefore counted as B vitamins themselves until recently. In ideal conditions, these cofactors can be produced by the body itself. Particularly when taking high doses of B vitamins, it is important to ensure a parallel supply of these compounds to avoid nutritional imbalances:

  • Choline (formerly vitamin B4) is mainly found in the form of phosphatidylcholine (lecithin) and acetylcholine.
  • Betaine (in the form of trimethylglycine/TMG) is another activated form of choline which plays an important role in the methylation cycle as well as in homocysteine metabolism.
  • Inositol (formerly vitamin B8) is found primarily in the brain, liver and kidneys.
  • PABA (formerly vitamin B10) functions as a coenzyme and is involved in the formation of red blood cells via vitamin B9.
