Just so you're aware, as I stopped taking Alpha GPC because of this, but Alpha GPC has been possibly implicated in adverse cardiovascular events.

"Recently, concerns have been raised about the potential of alpha-GPC to increase the risk of cardiovascular disease (CVD) because it serves as a substrate for the synthesis of trimethylamine-N-oxide (TMAO) in the gut, and TMAO is associated with adverse cardiovascular outcomes in people with CVD and in mechanistic studies.

A 2021 cohort study of more than 12 million participants (at least 50 years old), including 108,877 alpha-GPC users, reported that alpha-GPC use for at least 12 months was associated with an increased risk of stroke over 10 years. Moreover, a 2021 mouse study found that alpha-GPC supplementation promoted atherosclerosis.

However, the currently available evidence is preliminary in nature, so randomized controlled trials and large cohort studies are needed to confirm these findings."

I am aware of this. I am doing my blood test every 3 months where i check TMAO levels too. I managed to get the levels back to my base line with garlic extract. I think Andrew Huberman mentioned it somewhere. Also important, I don’t take Alpha GPC every day. Maybe 3 to 4 days a week

I found the same eating vegetarian when I tried it a while back

I think it was due to eating less heavy foods in general and less oil/grease
