How are we different?

We use the highly bioavailable form of choline bitartrate, which is a precursor of phosphatidylcholine (lecithin) and component of cell membranes. Choline in the form of choline bitartrate is 7 times more bioavailable in comparison to the direct cell component lecithin

We place value on the gentle production of ingredients without the use of additives or auxiliary materials, even those that we would not be legally required to disclose. Many generic supplements contain microcrystalline cellulose with nanoparticles which we are careful to avoid. Additionally, during production anti-caking agents such as silicon dioxide may be used which we also do not permit in our products. At Sunday we furthermore exclude unnatural additives used in the production of capsules, including lubricants.

Choline was long counted among the B vitamins as B4. Today, it is considered a semi-essential vitaminoid, since the body can cover part of the requirement through self-synthesis. However, it is not known by scientists if this self-synthesis is really sufficient.

Choline plays an important role in a number of bodily functions. In the fat metabolism of the liver, it supports its enzyme system and is an important component of bile secretion. Choline furthermore has an important transport function in fat metabolism: as a component of VLDL (Very Low Density Lipoproteins), it transports fat and cholesterol from the liver to other bodily tissues that need these compounds. Choline also plays a role as a methyl group donor. Just like betaine, vitamin-B12, folate and S-adenosylmethionine, it helps to regulate homocysteine levels.

Furthermore, choline is involved in production of various neurotransmitters (e.g. acetyl choline) and is one of the main components of cell membranes and myelin sheaths of nerve cells (e.g. phosphatidylcholine).

Health Benefits of Choline (According to EFSA)

  • Choline contributes to normal homocysteine metabolism
  • Choline contributes to normal lipid metabolism
  • Choline contributes to maintenance of normal liver function
