Looking at the article.
Consuming Butyrate, available online will boost levels.
Butyric acid has a nasty odor. Is this stuff sufficiently different so as to avoid that problem?

The easiest way to feed this bacteria is via resistant starch. It is a starch that passes through the small intestine undigested. When it gets to the large intestine the bacteria feed on it and produce butyric acid as a by product. The best food sources are potato starch and green bananas. You can buy the potato starch and stir in a few teaspoons into a smoothie. You shouldn’t heat it. Alternatively you can boil, steam or microwave potatoes (preferably whole). Allow to cool a bit and cool further in the fridge (overnight is good). Eat them cold. Green bananas are good but not that palatable. Rolled oats brought to a boil and cooled as per potatoes is another good source. Oats have a fair amount of phytic acid in them so eat a vitamin C rich food with them. Like cooled oats and orange juice. You can expect a little wind. Nothing out of the ordinary. Once the gut bacteria start cranking out the butyric you will sleep better. Dream better. Have more get up and go. I have been doing this for months now and I feel more alive.
