“Alpha-GPC actually had the same affect on me every day for more than a year, maybe even 18-months. Then suddenly the effects changed dramatically and it made me feel so horrible, physically sick and horribly depressed and anxious. I tried diferent brands and the effects were the same. I tried taking very long breaks and still the same. My theory is that Alpha-GPC permanently fixed a deficiency that I had. I am not sure if that’s scientifically possible, but that is my experience. I loved it, but now cannot tolerate it at all.”
U/BAKED_POTATO123 ↗“Still taking it but less frequently than before, and I switched to CDP-Choline as my daily driver. The TMAO link is real but worth putting in context. The studies showing elevated TMAO from choline supplementation are mostly observational, and TMAO from supplements behaves differently than TMAO from red meat which is where most of the cardiovascular data actually comes from.”
U/NOISEPROOFSTACK ↗“I got the Jarrow brand 300 mg formulation and have been taking 2 per day. One in the morning, one early afternoon. It’s now been a full week and my review is still nothing but positive. All of my relationships are improving, work, home, love, even with myself. I was looking for something and I believe I found it with alpha gpc.”

Add context that might help others — skin type, conditions like PCOS, what you'd tried before. The more specific, the more useful.
