Oh my goodness this stuff is absolutely amazing! I had heard that it is good to help gut problems like IBS-D so i ordered a bottle. Started taking 1 cap 4 times per day (hr before breakfast, hr before lunch, hr before dinner, just before bed). I increased that to 2 x caps each time and by the second day my stools were normal YAY! After about 4 days i noticed my mood was permanently fantastic! Things that would normally stress me out were not irritating or affecting me at all. I was totally amazed. Been taking these for 2 weeks now and my long term irritability has vanished and my stools are consistently formed. They say our gut is closely linked to our brain, this stuff proves it :) Will not be without it!

I was told by my trainer to use L Glutamine before and after workouts. It seems to provide a little burst of extra energy and prevents undue soreness.

I bought this supplement after reading that taking 2g of L-Glutamine before bed has been proven to cause an increase in HGH. I haven't had my before-and-after HGH levels measured, but something my husband & I are doing has significantly increased our energy levels, mental clarity and immune responses (no sicknesses since we started our low-carb, high nutrient, no-sugar regime + selected supplements a few months ago), so this one seems to be doing its part. We both take 2g of it every night before bed -- that's the recommendation I've read.

L-Glutamine is highly effective on me but effect wear off after about 10 days. Really improve concentration 20 minutes after ingestion for about 1 -2 hours.

I have found that Glutamine works to increase my energy and alertness. I highly recommend it to help those with low energy, alertness, and even focus problems due to fatigue.

The value is excellent - half the price I was paying for L-glutamine at my local gym. An essential supplement for anyone wanting to build muscle, especially important if cutting calories to lose fat at the same time.
