Ignore if you're not fasting.
One of the reasons to do intermittent fasting is to avoid signaling 'food available' to mTOR - a very large molecule in the cell that seems to mediate the cell's reaction to nutrients - or the lack of them. It's known to react to glucose (sugar) and glutamaic acid (umami taste), and there's some evidence that it senses other amino acids. I've seen nothing on this amino acid, but have seen isoleucine, which is in gelatin. If you're not fasting, this is a don't-care. Same if you're only fasting to essentially 'exercise' your body's ability to switch from sugar metabolism to lipids and back as there'd be no glucose spike.
