When taking together, it is difficult to know which is doing what.

For me the acetyl carnitine seems to affect muscles more. It improves stamina for me. I used to use a gram a day when working out. When not working out 250mg is enough most days for me.

The RALA seems to do things in the brain and improve cognition and alertness.

If you stop the carnitine for a week or so, you might notice what it is doing for you. Carnitine is basically easily to tolerate, and the expense is what most people don't like about it. So keeping it as low as possible, helps with cash outlay issues. It has limited absorption in the GI tract so divide up large doses. If taken all at once, it may mostly be wasted.

My arthritis is flaring up this week, and that clouds my PN issues quite a bit. I don't know if it was a weather trigger or a mild viral attack of some kind. Today I seem better though. I've been on magnets and Aleve for most of the week. Also hitting the magnesium lotion more heavily too.
