D-light-full CDP-Cholin Citicolin

Citicoline plays an important role in the production of neurotransmitters in the brain. It is often used for general improvement of cognitive performance during periods of high demand. Compared to other choline compounds such as the less expensive choline bitartrate, CDP-Choline Citicoline can act effectively directly in the brain since it can pass the blood-brain barrier.

Update: Vitamin D3 study at the Charité in Berlin

Between 2019 and 2025, D-light-full supported the first major longitudinal study in Germany, conducted at the Charité in Berlin, into the effects of high-dose vitamin D3 therapy for multiple sclerosis (MS), following on from the ultra-high-dose vitamin D therapy trial. The results are expected to be published by the end of 2026. We provided vouchers worth €60,000 for study participants. This ensured that all participants used a high-quality vitamin D supplement with a guaranteed dosage and high bioavailability. We would like to thank Coimbraprotokoll gUGmbH and the NeuroCure Research Centre at the Charité for their trust in our products!
