I recall OTC L-Tryptophan was illegal years ago.

Being diabetic, fats & protein are important. But not all fat & protein sources are alike.

Do we have a Paleo Ping list?

Not that I know of. The Cancer Warriors have already been pinged by Tired of Taxes.

Yes, it was. The reason for that was that one Asian company, out of the dozens that make it worldwide, took shortcuts in its manufacturing process and created a toxic product.

The FDA banned all sales of L-Tryptophan for many years based on that incident.

L- Tryptophan was made illegal as a knee jerk reaction to a bad batch that circulated. I believe D-Tryptophan was the contaminant.
Anyhow, lots of L-Tryptophan in turkey. Thus John Madden referring to it as “trip the fan” during one Thanksgiving football game.
