Headache

I developed a terrible headache after taking this blend. I didn’t give up after the first day.. I actually skipped the second day and took the pills the on the 3rd day, and developed another headache. Maybe I’ll try the acetyl without the arginate blend...

Best Acetyl-L-Carnitine supplement

Excellent supplement! Having the Arginine in addition to the Acetyl-L-Carnitine is a huge bonus for memory support!

Gives me headaches and I’m unable to return.

Easy to swallow and I heard good things about this, as it came highly recommended but it gives me headaches 30 minutes after taking it.
