Berberine Beats Crestor? This is BIG!

Berberine treats atherosclerosis via a vitamine-like effect down-regulating Choline-TMA-TMAO production pathway in gut microbiota
Trimethylamine-N-oxide (TMAO) derived from the gut microbiota is an atherogenic metabolite. This study investigates whether or not berberine (BBR) could reduce TMAO production in the gut microbiota and treat atherosclerosis. Effects of BBR on TMAO production in the gut microbiota, as well as on plaque development in atherosclerosis were investigated in the culture of animal intestinal bacterial, HFD-fed animals and atherosclerotic patients, respectively.
We found that oral BBR in animals lowers TMAO biosynthesis in intestine through interacting with the enzyme/co-enzyme of choline-trimethylamine lyase (CutC) and flavin-containing monooxygenase (FMO) in the gut microbiota. This action was performed by BBR's metabolite dihydroberberine (a reductive BBR by nitroreductase in the gut microbiota), via a vitamine-like effect down-regulating Choline-TMA-TMAO production pathway.Oral BBR decreased TMAO production in animal intestine, lowered blood TMAO and interrupted plaque formation in blood vessels in the HFD-fed hamsters.
Moreover, 21 patients with atherosclerosis exhibited the average decrease of plaque score by 3.2% after oral BBR (0.5 g, bid) for 4 months (*P < 0.05, n = 21); whereas the plaque score in patients treated with rosuvastatin plus aspirin, or clopidogrel sulfate or ticagrelor (4 months, n = 12) increased by 1.9%. TMA and TMAO in patients decreased by 38 and 29% in faeces (*P < 0.05; *P < 0.05), and 37 and 35% in plasma (***P < 0.001; *P < 0.05), after 4 months on BBR. BBR might treat atherosclerotic plaque at least partially through decreasing TMAO in a mode of action similar to that of vitamins.

I find this study very interesting, as the danger of TMAO has been downplayed in the past. Seafood is high in both choline and TMA (which is metabolized to TMAO) itself (the fishy odor is actual TMA). A seafood meal has been shown to spike urinary TMAO quite high, so why don't cultures consuming substantial dietary seafood (Japan) have notoriously wicked rates of heart disease?
Another fun fact; I've seen berberine poo-pooed as as an effective supplement, as it is notoriously poorly absorbed. This study appears to indicate berberine does its best work inside the gut. If it never made it to the colon, it would not downregulate TMAO!

"Pass the liver and egg yolks please. And maybe some folks fasting for Lent may say pass the fish, shrimp or octopus. Consuming these choline-rich foods will produce much better mental health than worrying in the face of contrary evidence that they are clogging your arteries."
These guys say lecithin & dietary choline DO cause TMAO spikes, and they are in fact harmful: Intestinal Microbial Metabolism of Phosphatidylcholine and Cardiovascular Risk

"Increased plasma levels of TMAO were associated with an increased risk of a major adverse cardiovascular event"

Perhaps we can have our cake and eat it too? Just have a 500mg cap of berberine with every high choline meal!
Stay Healthy My Friends!
