CDP-Choline, also called citicoline, is a naturally-occuring compound and nootropic that is typically supplemented to improve cognitive performance. Inositol, also referred to as Vitamin B8, is a molecule that is structurally similar to glucose. This was even after controlling for age, sex, and smoking status.20https://www.ncbi.nlm.nih.gov/pubmed/20875835 Am i better off taking 250mg every 2 or 3 days? By preventing overstimulation of striatal DA receptors, uridine may help promote more stable and consistent levels of circulating DA in the brain. Rats were subjected to eight weeks of a food-reinforced running-wheel exercise. I would like to give some food for thought: uridine and citicoline are probably redundant, because supplementation of one increase the other; the oral dosage for citicoline for a person of 75kg would be of about 1000mg, but as I know, sublingual administration increase bioavailability by a factor of 4-5, so the sublingual dosage shoud be 200-250mg to achieve 11% increase in D2 receptors (I don’t think that it is worth trying to achieve the 18% increase, because to less than double the dosage you have to increase dosage by a factor of five); even if percentage of receptors increase with inositol is not reported, I don’t think is negligible, because at high dosage it has the same efficacy of SSRIs for OCD and there are studies that reports a noticeable increase in SSRIs for OCD; about forskoline I don’t have a reference on dosage, but it worried me more than others supplements due to the risk of developing mania (inositol don’t increase responsiveness to amphetamine like substance, while forskoline does). Lately, the mental health benefits of exercise are gaining a lot of traction. CDP Choline works best for me at 125mg/day in the morning. For example, many people debate between taking CDP Choline (Citicoline) and Uridine, but you should base your decision on the type of stack that you are building and exactly what you want to achieve. Interestingly, D1 receptor densities were decreased.9http://www.ncbi.nlm.nih.gov/pubmed/9353595, In this third study relating to forskolin supplementation, similar results were found. So they both serve the same general purpose: a choline source so the body can make more acetylcholine but are metabolized differently, because they both shortcut to different parts of the acetylcholine production cycle. In one study, CDP-choline was provided to aged rats over the course of seven months. The long-term meditators were found to have blinked less often and had a different pattern from the the new meditators.17https://www.ncbi.nlm.nih.gov/pubmed/26871460, The study concluded that “long term meditation practice induces stable changes in baseline striatal DA functioning.”17https://www.ncbi.nlm.nih.gov/pubmed/26871460. My first two weeks i felt amazing, but just the last few days i started to feel a little down. The herb was shockingly good I take daily doses of tianeptine sulphate and CDP form of choline,will probably add in forskolin and uridine but these have made a big difference in motivation energy mood and focus so I can vouch for a few of these. CDP-choline was discovered in 1955. This post is already too long so I'll get to the point - I'm interested in starting up a cdp-choline regimen once again, but I have reasons to suspect that I could run into choline related depression with frequent dosing. With tianeptine gone now, you’re basically left with uridine/cdp choline, inositol, and forskolin. Have you noticed any of the classic pro-choline effects from phosphatidylcholine, verbal fluency, memory benefits, etc.? CDP-choline, or citicoline, is an intermediate in the synthesis of phospholipids, which are essential components in the assembly and repair of cell and mitochondrial membranes.Therefore, CDP-choline may have neuroprotective qualities as well as therapeutic effects in Parkinson’s disease. In order to get the same bang for your buck, you have to push the stakes higher, effectively pulling from an ever shrinking store of dopamine. Here, the authors stated that meditation has been shown to affect cognitive functions such as mind wandering, cognitive flexibility, and attention. CDP Choline (also known as Citicoline or Cytidine diphosphocholine) is a potent nootropic and a highly bioavailable choline source that is praised for its ability to cross the blood-brain barrier quickly, improving memory and protecting the brain against memory injury. It’s just scary when that happens. Because Citicoline is water soluble, the body readily absorbs it into the bloodstream, giving it a 90% bioavailability rate and increasing its effectiveness. “The herb was shockingly good”. This is because DA receptor densities decrease with age, at a rate of about 3% per decade.6https://bpspubs.onlinelibrary.wiley.com/doi/pdf/10.1111/j.1476-5381.1991.tb12471.x. If you can’t do everything at once? Skip Inositol because you need to take so much? I’m curious what makes you think that for example the inositol induced increase in dopamine receptor density will stay after you stop taking inositol. Meth and Cocaine Addiction Citicoline reduced depression in 60 methamphetamine (meth) addicts but didn’t impact drug use (2,000 mg/day for 3 … In regards to receptor densities, forskolin increased D2L receptor densities by 43%, and increased of D2S receptor densities by 107.5%.9http://www.ncbi.nlm.nih.gov/pubmed/9353595. No issues at all. CDP-Choline is unique as a choline source. Inositol is considered a pseudovitamin, as inositol is metaboized in the kidneys from glucose. Do you mind if I ask some questions about your historical usage: 3-Have you seen tolerance effects (need more to get the same effect). The Choline element of CDP Choline is thought to directly increase levels of norepinephrine and epinephrine, while the Uridine element is thought to strengthen dopaminergic signalling. Dopamine is essential for our pleasure and reward system. I’m a 38-year-old male and in fairly good health. Your email address will not be published. The meditation, excersise and b8 didnt give any actual data for the increase which leads me to believe receptor density increase by these methods are negligible. That said I do think some of the supplements may induce lasting changing even upon cessation, uridine for instance actually repairs dopaminergic neurons and that in and of itself is a long-lasting effect. Hence, CDP-choline is traditionally grouped with cholinergic rather than dopaminergic supplements. This was accomplished by comparing 68 volunteers who had either high levels of sunlight exposure or low levels sunlight exposure. Hi all, several years ago I collected a lot of research and notes about neurotransmitters and it’s modulators. CDP-choline is a nootropic compound that is essentially a prodrug for both choline and uridine, conferring both of those molecules to the body following oral ingestion of CDP-Choline.Specifically, the CDP-choline dissociates into choline and cytidine, with the cytidine then converting into uridine. There is now an increasingly large amount of evidence that exercise can increases DA receptor availability in the striatum.11https://www.ncbi.nlm.nih.gov/pubmed/26503310, In one study, exercise was shown to reduce the neurological damage that occurs from methamphetamine abuse. Any experience with CDP + caffeine? However, the only foods that contain any appreciable amount of CDP-choline are liver, brain, and other organ meats. CDP Choline, also known as Citicoline, is a supplement for cerebral metabolism. I would be very surprised if it is longer than 4hrs. So things like Memantine and huperzine A don’t fall into that category because they; as I understand it – are used to ward off tolerance if one uses ADD medications. In this study, the goal was to identify the correlation between sunshine exposure and DA levels. This list will include both supplements and physical tasks; I will attempt to explain the mechanisms behind each in relationship to this goal. I already take a stack with Alcar, NALT, and P.S. In the one treated group, a dose of 100mg/kg was used, and an 11% increase of DA receptor densities was found. Citicoline, also known as CDP-choline, is a chemical produced naturally in our brains. Discussion of nootropics and cognitive enhancers. If you want to skip ahead you can feel free to do so, but this information is worth knowing. When the body performs positive behavior patterns, the release of dopamine acts as a reward for these behaviors and motivates us to continue seeking that feeling – hence its nickname as the ‘motivation molecule.’ Achievements su… I hear that if you can take under 150mg per day you can prevent the depressive feeling, but is that dose actually effective? She must have been talking about the forskolin extract. One very interesting study measured spontaneous eyeblink rates, which is strongly correlated with striatal DA activity. But researchers have also noted that CDP-choline has dopaminergic effects. This process is commonly referred to as reuptake inhibition. https://www.ncbi.nlm.nih.gov/pubmed/8372096, https://www.sciencedirect.com/science/article/pii/009130579500169W, https://www.ncbi.nlm.nih.gov/m/pubmed/20504471, https://www.ncbi.nlm.nih.gov/pubmed/2906500, https://www.ncbi.nlm.nih.gov/pubmed/16055952, www.ncbi.nlm.nih.gov/pmc/articles/PMC1908237/, https://bpspubs.onlinelibrary.wiley.com/doi/pdf/10.1111/j.1476-5381.1991.tb12471.x, https://www.tandfonline.com/doi/abs/10.1080/10623320600934341, http://www.ncbi.nlm.nih.gov/pubmed/9353595, https://www.sciencedirect.com/science/article/pii/0922410694900817, https://www.ncbi.nlm.nih.gov/pubmed/1352895, https://www.ncbi.nlm.nih.gov/pubmed/11267629, https://www.ncbi.nlm.nih.gov/pubmed/26503310, https://www.mdpi.com/2076-3425/3/1/39/htm, https://www.ncbi.nlm.nih.gov/pubmed/20875835, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3044190/, https://www.ncbi.nlm.nih.gov/pubmed/11958969/, https://www.ncbi.nlm.nih.gov/pubmed/26871460, https://www.ncbi.nlm.nih.gov/pubmed/9376541, ttps://www.ncbi.nlm.nih.gov/pubmed/26503310, https://www.ncbi.nlm.nih.gov/pubmed/11981225, How to Upregulate Dopamine Over the Long-Term, Fasoracetam, the Latest Member of the Racetam Family, N-Acetyl Cysteine (NAC) – The Ultimate Brain Health Supplement, Coluracetam, an Exotic Cognitive Enhancer, Alcohol Defense – The Hangover Cure That Actually Works, Red Reishi Mushrooms for Reducing Inflammation, Becomes sensitized to DA by increasing its availability to be absorbed.
