Excellent!
Let me start by saying over the last 10+ years I've tried just about every brain supplement I could get my hands on. I work in a very fast-paced work environment that demands a high-performance brain. I've now been taking this product for almost a year and it's been the only supplement that has made a lasting noticeable change with me. Others are very inconsistent with good days and off days but X-brain is the only one so far that is pretty consistent every single day. I'd recommend it to anyone...and I do!
