I've been thinking for some time about how carbs affect my mood and considering other people's anecdotal reports. I recently read Lyle McDonald's
Carbohydrate Intake and Depression - Q&A and (while he doesn't directly recommend this supplement) I'm looking for information on supplementing with L-Tryptophan. I've been googling and most of what I've found is anecdotal, over my head, or a sales pitch from someplace that just happens to sell L-Tryptophan.
Also Lidtke appears to sell USP certified L-Tryptophan. Anyone have any experience with them?
