I was taking 250mg CDP 2x a day and have noticed brain fog/tiredness. Any thoughts?

 

Current Regimen:
Centrum Multi 1x Morning

2.4g Piracitam 2x Day
1.2g Omega-3 2x Day
5k IU Vitamin D Every Other Day
1000mg Ester-C 1x Morning

250mg twice a day is a massive dose... CDP choline's half-life is like 4-5 days... you're accumulating significant amounts in your body at that dose, i'm surprised you haven't gotten any neck stiffness from it

 

to compare... i take 50mg once a day with 2 racetams...

Hmmm, I was just reading the bottle and it states to use 2 caps of 250mg per day.

when i first got CDP choline... i was also doing 250mg BID... and within 3 days i got bad neck pain and brain fog... I thought I was doing everything right and it just didn't make sense... until i researched the half-life and then cut back my dose down to 50mg... now with 50mg a day i experience no headaches or brain fog and can utilize my racetams more effectively... and sometimes when i've had a more stressed day or if i'm doing a ton of reading and analyzing, i'll take maybe 20mg or 30mg more in response to racetam headaches, but i don't go anywhere near 250mg even once a day...

This is interesting. What if I took one 250 mg capsule before bed and didn't take anymore for 4-5 days or maybe a day sooner depending on how I felt? Could I do that instead of messing with micro 50 mg doses? CDP choline makes me really tired for some reason which is why I mention taking it before bed. It also gives me a massive erection, but what good is that if I want to fall asleep haha.

if you can handle a 250 dose without getting side effects like cognitive dulling or stiff-neck then that would work. but be careful about stacking with other nootropics... for example of you took coluracetam, which enhances choline uptake, then you're enhancing the uptake of choline on top of giving yourself a 250mg dose of CDP... so make sure to do your research carefully when you stack that kind of dose with other nootropics

Well, since the cdp makes me tired I guess the negative effects don't matter much cause I'll be asleep. The only other nootropic I take right now is noopept and I'm having varying results with that.

To my understanding noopept only depletes choline stores a little bit, not as much as say piracetam. So I should be ok yea?

Thank you for this. I'm glad I hung onto my bottle of citicoline, I'll try your method

I believe the only potential issue with choline intake at night is you will not get the full potential of memory consolidation.

Weird my post didnt go up. Examine.com recommends Choline Bitartrate at the level the op is doing, but not for cdp. I always wonder why they put the dose they do on bottles. When ai take Choline with my b complex i sleep like a baby

Could someone please clarify the issue with choline at night and memory consolidation issues.

 

Is it recommended for b complex to be taken before bed?

I took one 300mg alpha gpc cap and one 250mg cdp choline cap last night a couple hours before bed. Slept soundly and for 10 hours without waking up. Woke feeling pretty refreshed with a very minor headache and a slight bit of tension but really nothing bothersome. I like both of these choline sources for their varying effects which is why I took them together. I suppose if I took this once a week say on a friday night it might be beneficial. I could never sleep 10 hours on my work days haha. Theres just no time for that.

Nice. I took a 750 mg cap of aniracetam and the headache is dissipating some. Maybe a slight lift in mood but thats about it so far.

I've never taken b2 by itself, but I do take a b complex in the morning which balances my mood some. Don't take b6 by itself in the morning though, that just about knocked me out before work. It was not good lol. Turns out it is good for sleep.

Is it necessary for me to take more cdp or alpha gpc then what I have taken for the week if I was taking 1400mg of aniracetam a day? I'm not going to at the moment, gonna wait it out a few days and see if I get any headaches. I know one thing though, the low grade headache I had earlier today was due to the high dose of choline I took last night and once I took the aniracetam the headache left quickly, about 45 minutes.

i think the best way to deal with choline supplementation is to take it in response to racetam headaches instead of the other way around. if choline in your brain gets too low, racetams will let you know by giving you a headache... and that headache goes away within 30 min by taking a choline supp.

 

taking it your way will create excess choline... and removing/reducing something that's already in your body is harder/riskier than replacing something that's low in your body.

Thanks for the reply! I have one other question that I've gotten mixed answers on. Should I take cdp choline before taking aniracetam or after?

Thanks for the reply! I have one other question that I've gotten mixed answers on. Should I take cdp choline before taking aniracetam or after?

 

once you know how you respond to aniracetam (i.e. how often you might get racetam headaches), you'll know if you need a daily CDP intake or just taking it as needed.

 

therefore take it after aniracetam and in response to a headache. from my personal experience, I have gotten racetam headaches maybe twice but have gotten choline overload a handful more times... and I take CDP 50mg once a day every day. the 50mg dose works best for me to minimize choline overload and my track record for racetam headaches means the baseline CDP intake is keeping them at bay.

Choline makes me depressed.

 

The best explanation I could find for this issue was the balance between choline and other neurotransmitters. If ACh is too high then it displaces? dopamine and serotonin.

 

I run naturally high on choline (or maybe just naturally low on other neurotransmitters), I stay away from choline after trying ALCAR, CDP and A-GPC.

If you look at studies using Citiocholine doses are almost always 1gram + a day. There are rarely any adverse effects recorded and those that are very minor. After about 5-10 days a stable dose will appear in the tissues. I took Citocholine for a few weeks at around 1-2g a day and had nothing but positive effects.

I've been taking cdp choline off and on this week and found it makes me tired. I also noticed that if I take to much it dampens the effects of aniracetam. I find Aniracetam really lifts my mood, relieves anxiety, and give me a certain clarity and calmness in my mind. Its like my mind becomes still and I can really focus and take in everything thats happening around me right now in the moment. If I take to much cdp choline I find myself tired, irritable, and in a negative mood and dampens out all of those positive effects of aniracetam. So finding the right balance I'm finding is crucial.

I took 250 mg CDP-Choline (LEF) two days ago in the morning. Nothing noteworthy so far during that day. Yesterday I took one 250 mg CDP-Choline in the morning and another around 2.00 p.m.. After about 60-90 mins I became really tired and had to take a 2 h nap on the couch, which is absolutely uncommon for me.

So the tiredness-inducing phenomenon seems to have ocurred... It would be interesting to have blood-melatonin values in those who become tired after CDP Choline... I will try it again and possibly will take the second portion in the evening then.... How about gene polymorphisms in those individuals who become tired taking CDP-choline...

addendum:

the phenomenon of becoming tired after CDP-choline did not happen again and in order not to produce exaggerated experiences I am posting this addendum.

I use CDP-Choline 250 mg: 1-1-0,Uridine 1-0-0 with two days off /week.
