So not the same as the LOLA supplement but I have taken this:

For years, I'd use it just once in a while and noticed that sometimes when I took it right before bed, I'd wake very slight refreshed for about 20 minutes before my day would crash back to normal.
I always felt it must be helping to lower ammonia. Plus, I've also used it as an antidote two times when I trialed amino acid supplements. Within a very short time after taking the aminos, my neck and shoulder muscles were burning like they were being flooded with liquid fire (ammonia?). The pain moved from there down my spine and eventually even into my legs. It was bad and it happened both times I trialed amino supplements.
Once I figured out that it could be ammonia I took that supplement. It reduced the symptoms a lot and again in just a short time...though not completely.
I've also purchased a different brand from Piping Rock that doesn't have the mucuna or the Alpha-GPC. It doesn't seem to work as well.
Anyway, now I take it daily because once I got my Garmin watch, I noticed this product and later oregano oil (unrelated) lowers my heart rate. It's nice since I feel I also have OI issues. (Again, the Piping Rock brand doesn't seem to do this as much.)
Two more things: I have taken just L-ornithine (and L-Citrulline) by themselves but don't seem to get the same benefit as this product and Yucca is another supplement that is supposed to reduce ammonia but I haven't tried it.
