If I go low on carbs like you I shouldn't take them both?
Again - everyone is different - but I definitely wouldn't. When I first started taking the Fd2 I was taking it on empty stomach or with low carb meals and I felt like garbage for over a week. Nothing completely terrible, but stomach upset/clammy/dizzy. Brundell was awesome and helped me out with the dosage - once I started taking with carbs the issues completely went away.
So if you wanted to keep the R-ALA, I'd think you'd need to keep your carbs up. I find even 20g of carbs to be plenty for me to take the Fd2 and not have an issue. Usually I try to have 30+ if I'm taking 2 caps. I still take a 1 cap dose fasted once in a while when I workout on empty stomach on the weekends, and think I've adjusted to have it not affect me AS much
So if you were going to use both, I'd definitely recommend breaking up the carbs so you have some with each dose. I definitely wouldn't take the pills at once
