Bacopa Monnieri + Gingko Biloba and Lion's mane mushroom have contributed individually or all together to excellent memory retention although I feel the introduction of CDP-Choline along with the Alpha GPC and morning eggs could potentially be negatively affecting these gains?
I've stopped taking all of these nootropics, the only thing I consume now is:
Vitamin D3
Zinc Gluconate
Vitamin B Complex
Before I stopped with last stack I completey cut out Alpha GPC, CDP Choline and Tyrosine in the middle/end of Feb.
I added Ashwagandha which I believe to have been a mistake in my opinion as I feel it has negatively affected my ability to think clearly and led to very frequent mood fluctuations.
For now I'll just stick with the vitamins I'm on, I still have eggs every 2nd to 3rd day instead of daily.
