Phosphatidylcholine, acetyl-l-carnitine and magnesium for managing bipolar states

I am developing a hypothesis for the management of bipolar states through the supplementation of phosphatidylcholine at the onset of a manic phase, and acetyl-l-carnitine at the onset of a depressive phase, to even out the peaks and troughs. The full regime would involve a low-carbohydrate medium-fat diet and ad hoc magnesium supplementation.
